Notes from the Lab
Sort of. We finally had a chance to say THANK YOU to Jayne Dearborn, the Board of Max Blue Butterfly Campaign and Guests at the Fundraiser last October event. Max Blue Butterfly campaign continues to support our Leukemia biomarker project. Funds we received in 2014 had allowed us to show how small vesicles that circulate in the bloodstream can make for a new tool to discover leukemia relapse earlier than currently possible. That was in mice. Funds this time around will allow us to finally look at AML samples directly, and show how vesicles in the blood can be used to track and detect recurring leukemia.
Receiving a very welcome check: Peter flanked by Jayne Dearborn, Founder and President of Max Blue Butterfly Campaign and Jim Ervin, Executive Director of the Doernbecher Foundation.
All over the place!
"Feast or famine" seems to describe the flow of research and scientific publication pretty well. The work of many years and countless hours, all published within a short period of about 4 weeks. Certainly a banner monthfor several current and former members, as all three projects seemed to have reachedthat critical stage at more or less the same time.
Congratulations to all first(Noah, Ben, Young and Natalya) and co- (Santhosh, Sherif, Ashley, Kelsie)authors, as well as and our collaborators! Cool.
Santhosh discusses ournew gene therapy vector at the Annual Fanconi Anemia Meeting
More a road trip than business travel, we bolt-bussed it to Bellevuein September for the Annual Scientific Meeting of the Fanconi Anemia Research Fund. Santhosh had been invited to present an update on his episome gene therapy vector. With a broad audience from clinical to basic science investigators he found a friendly crowd at poster sessions and during his presentation. The match up with several presentations on clinical gene therapy trial updates may have been ambitious, but it certainly provided proper perspective. Company was great and discussions stimulating.
Kurre lab Alumni present as well: Ashley, on a break from labwork in Cambridge (UK).

Retreat from the heat!
Back by popular demand, or maybe Peter's whim, we left Portland for a well deserved lab retreat on the Oregon coast. It was nice to trade cell culture dishes, pipets and computers for nets, bait and buoys. Motoring around Nehalem bay proved to be fun and the drizzle was limited to the first hour. While in the end we may have failed in catching all the crabs we wanted to eat, we did fine with Pizza and it was great to catch up on what everyone was up to outside the lab.
Great fun and a few months to let the sunburn fade before next year's retreat.

As in years past, we participate in the 2016 Murdoch Trust Summer Internship Program and welcomed Michael Morin earlier this week. Michael just finished his Junior year at Linfield College and will spend the next few months working alongside Sherif on a project: Assay of Exosome miRNA as Minimally Invasive Biomarker for AML.
The Murdock selection is highlycompetitive and champions talented undergraduates to spend a summer of scienceimmersion and networking at OHSU followed by continued research involvement forthe subsequent academic year and capped by a Project Summary. The program(under guidance of Dr. Kent Thornburg) has been particularly effective inguiding students toward careers in biomedical science and was recently refunded.Periodic Table (of-chemical-elements) bowtie;nice touch, Michael!

And that's a wrap - Natalya is snowbound for the University of Minnesota
New beginnings all around. Bringing to its culmination a spring/ summer of farewells, we said our goodbyes to Natalya who enrolled in Graduate School at the University of Minnesota. During the past four years, she put her stamp on nearly every project in the lab and taught several "generations" of interns and fellows the ropes in the lab. No longer the wide eyed college graduate, she finished her time in style, directing activities in the lab and writing up her last experiments for publication. We will miss having her around and can't really imagine how to replace her Russian honeycake lab meeting treats. Also hard to imagine anyone better prepared for Graduate School. We expect great things.
June 16, 2015
With summer comes the annual ritual of graduation and farewells. And with so many on the team transitioning to their next career stages, work in the lab certainly won't be quite the same.
Ashley was the first to move on and has been on a well-deserved hiatus before picking up her post doc studies at the MRC in Cambridge, UK this summer. Reason enough to get everyone together for a send-off and head out this past week for a lab lunch at the OHSU Farmers Market.
Noah will soon resume his clinical rotations to complete the Medical School curriculum over the next two years and collect his next doctorate. Naturally moving on in style, with still a few experiments to go and always another paper to write.
Kelsie will follow her strengths and passions caring for kids with cancer while trying to balance playtime with Roe. As a committed Portlander she joins several previous Doernbecher fellowship graduates at Randall, across the river.
As for Shelton? The paper is out and we are worried! Moving to San Diego just sounds too much like SoCal Surfing Life, although he insists that the Navy actually has a job for him there. Actually, to be their Peds HemOnc Division Chief.
Natalya will matriculate with the University of Minnesota Graduate School Program in Molecular and Cell Biology, going out with the requisite burst in productivity and excitement. What a brain drain!
I could not be prouder of their individual achievements over the past few years and what everyone brought to the team. Grateful indeed and eager to watch their next steps.
Anyone else left? The stalwarts: Santhosh, Youngme, Jianya, Ben and our spectacular summer interns Merna and Kristina. Science and the lab will be in good hands with more to join soon. But that is another visit to the Farmers Market altogether.

Noah successfully defends his PhD Thesis - congratulations
Five years … lots of hard work with some long nights and weekends behind him, -as well as about 10 bike tire punctures and 2 replacement bike chains later- Noah defended his PhD Thesis. After having spent the better part of the past 3 months writing, editing and revising his PhD-thesis document, Noah finally had the opportunity to defend his dissertation. Cramming 5 years worth of studies into a 50-minute talk or even 140 pages of writing can be a challenge. Notwithstanding, Noah's seminar was as polished as his dissertation was complete. Much like Peter had predicted, the committee was no match for his insatiable appetite to consider a question and extemporize on its merits. In the end, all were satisfied and highly laudatory.
We could not be prouder of Noah's accomplishments and have a hard time imagining what things will look like around here once Noah returns to the Medical curriculum in July. For now, champagne, beer …and just a few more experiments? Well done.

Max Blue Butterfly fundraising for Doernbecher AML research
Max Blue Butterfly Campaign (based in Portland) has funded research to improve outcomes for children with AML. We had the opportunity to meet with founders Jayne and Chris Dearborn earlier this year and were delighted when they decided to dedicate their 2014 Fundraising to our work on early AML relapse detection.
The appeal at the Gala event in September was met with an outpouring of support and the group not only exceeded their stated 2014 goal, but all prior annual fundraising efforts. This past week Jayne visited with us at Doernbecher to present the check.
We are grateful for the confidence in our work and will be able to expand our efforts on developing exosome miRNA as biomarkers for early detection of childhood AML. Hard work by Jayne, the board and volunteers fills a critical gap in childhood cancer research funding.

Visiting the Capitol
Hyundai Hope on Wheels began to fund Childhood Cancer Research 16 years ago and has by now contributed a stunning $ 87 Mio to support the research mission at a number of US and Canadian institutions. $ 9 Mio were donated this year alone. Doernbecher-based cancer researchers have received an aggregate amount of over $1Mio in the last five years and all of us are grateful for the support. This especially, at a time when Federal (NIH) funding for Childhood Cancer research has been lacking.
As a 2014 Hyundai Scholar I had the opportunity to travel to Washington DC last week to meet some of the other grantees. The Thought Summit I attended was merely one of the events that were part of the Hyundai DC Days during Childhood Cancer Awareness Month. Others included the first Hyundai Hope on Wheels Scientific Symposium, a Gala Dinner at the Library of Congress and a visit with the Capitol Hill Childhood Cancer Caucus where Dr. Francis Collins (Director, NIH) gave a keynote speech. Perhaps I came away so impressed, because the money donated by Hyundai seemed to be thoroughly matched by advocacy for the cause.
Below a picture from the press conference on Capitol Hill when the grants were announced. Holding the check is Hyundai America CEO Dave Zuchowski. Also present were several members of the US House of Representatives, the Head of the Dealers Association and the Korean Ambassador to the US.

With all sorts of grant-, abstract- and manuscript deadlines met, it was time to take a break for our annual retreat. This year we headed to Garibaldi for a guided Kayak tour of Miami Cove followed by Picnic and a Hike to Cape Falcon. While we did not see any bald eagles or 4-foot long beavers, we did spend a glorious day with warm weather and spectacular views of the coastline. It was also a way of thanking Jennifer and Kendra for spending time with us during their summer internships. And about Natalya's Russian Honey Cake: delicious!
July 23, 2014
Why we do what we do? Ask Kendra
Summer in Portland - Interns join the lab. For several years we have had students at all levels (High School, College and Medical School) join us for a few months in the summer to learn about cancer and stem cells. This year, we were fortunate to have Kendra Jackson (Lake Oswego High School) and Jennifer Wherely (OHSU School of Medicine, Class of 2017) come on board. Both have been great team players, working on projects and helping others with their work.
Energy and enthusiasm go along way, and Kendra pitched in when a visiting videographer asked for something slightly more lively than Peter behind his office desk explaining exosomes. Kendra talked about one of the projects she is helping with, her time in the lab and the decision to spend her summer engaged in science at the OHSU-Papé Family Pediatric Research Institute. Inspiring! I see great things.

Commencement 2014 (Ashley receives her academic hood)
Ashley's PhD Thesis defense is a few months old, but that should not detract from this occasion. Arlene Schnitzer Hall was all decked out as family and friends lined up around the block to attend this year's Graduation Ceremony. Proceedings for the final "walk" across stage came underway with a series of speeches by students and faculty. Some them reflective, most hopeful, and all congratulatory. The awarding of honors and placement of the hood came off without glitches and only minor heckling. Once of those, as Ashley's father offered some (badly needed) help to the officiating faculty in pronouncing Ashley's full name. Three hours later, all was done and Dr. Kamimae-Lanning was in possession of her hard earned and well-deserved academic regalia. Many photos followed. Congratulations Ashley!

ASPHO 2014 – great meeting – great city
The American Society for Pediatric Hematology/Oncology (ASPHO) Meeting 2014 just concluded in Chicago. OHSU Doernbecher seemed to have a record contingent of delegates this year. And although some of us were delayed by air travel issues, once the meeting got underway we were well represented across the spectrum of committees, workshops, poster and oral presentations. And what an opportunity to reconnect with past trainees and strike up some new collaborations. Both Kelsie and Shelton presented their work in oral session to a friendly audience - validation for months of hard work and the occasional weekend effort. The conference venue was in the Loop area and, in spite of the drizzle-prone weather, Chicago was as welcoming and exciting as ever. Hey, Shelton even brought a tie !

A visit to the "Low Countries" for the Meeting of the International Society of Extracellular Vesicles
The International Society for Extracellular Vesicles (ISEV), founded only 3 years ago, meets once a year for scientists to present their findings and learn from each other! The group has grown form < 400 attendees (Gothenburg, Sweden 2012) to over 600 (Rotterdam, Netherlands 2014) with strong international representation and US scientists clearly in the minority. And while many others appeared to work on understanding the role of vesicles (exosomes) in cancer, not many studied Leukemia. This was our third participation and both Jianya and Noah presented their research in oral conference and to substantial interest. The many presentations left no doubt that exosomes are important in many aspects of cell and in particular cancer biology, and exploring how they regulate drug resistance and bone marrow suppression should prove fruitful and with significant translational impact.
Our conference venue (DeDoelen) was located in central Rotterdam, conducive to exploring on foot and taking in the many architectural sights - while carefully avoiding the ubiquitous bike traffic. Not sure we will see as many bikes in Bethesda or Chicago (to be decided) next year, but the 2015 ISEV conference will doubtless prove as valuable for the science of vesicles (pronounced vEEEsicles in the British idiom, it appears). The Pic? Jianya in suit and tie. Respect.

Reinventing bone marrow stem cell gene therapy
Almost a year ago, the FRIENDS OF DOERNBECHER funded our research project to develop "new and improved" gene therapy vectors that would provide enhanced safety for genetically modifying bone marrow stem cells.Santhosh and Natalya published a substantial part of that work this past month in the Scientific Journal Nucleic Acids Research. The journal article is nothing short of a 10-page tour-de-force in molecular biology to illustrate the ability of the new anchoring episome lentivector to persist without integrating into the cell's chromosomes. Santhosh had long favored the nautical themes (anchor!) for his lab meeting update slides on the project and that seemed to resonate with the journal reviewers who liked the new addition to vector nomenclature:"anchoring non-integrating lentivector, anILV ".
What's the big deal? The accidental integration of conventional vectors into the stem cell chromosomes can lead to skewing of the bone marrow stem cell pool and, in the extreme, leukemia. aniLV-episomes are anchored and stick around each dividing daughter cell, but they do not seem to integrate. The article also shows the power of teamwork, as Natalya and Santhosh worked together, complementing each other's expertise to complete these studies.
What is next? We will use the anILV vector to improve gene transfer to stem cells from Fanconi Anemia mice and demonstrate that episomes persist in the rapidly dividing bone marrow stem cell pool where they can genetically correct the hematopoietic failure that plagues FA patients.Episomes rule!

Noah receives a grant from the National Cancer Institute
In what we hope will be an auspicious beginning to the new year, Noah received some very good news from the National Cancer Institute when word came that his training grant was funded (a multi -year National Research Service Award, NRSA). At a time, when funding remains tight and the competition is strong, Noah’s proposal scored at an astounding 8% in his study section (the lower the number the better). The enthusiasm came through in the written critiques Noah had received from the scientific review committee, pointing out the overall strength of the applicant, project and OHSU as the scientific environment for the proposed work. The award represents a strong vote of confidence and validation for Noah’s hard work over the past year. A consummate teamplayer and problem-solver, never shy to embrace an argument, the committee saw in him a very promising scientist.
We agree, but someone else was more prophetic: The pic of a shipment received from collaborators 2 years ago. Congratulations Professor Hornick!

Ashley Kamimae-Lanning successfully defends her PhD-Thesis
A very big day, five years in the making: On December 18 Ashley successfully defended her Thesis: “ Programming of the fetal Hematopoietic Stem and Progenitor Cell Compartment”. In front of friends, family (with parents watching via video conference) her undergraduate research advisor, OHSU students and faculty she gave a polished presentation and navigated the subsequent questions with ease and confidence. Evenings and weekends of hard work pay off as the leaves behind the student days to receive her PhD. Much was accomplished during those five years: Lab meetings, conference presentations, grants, awards, and papers published. (And her first passport for international travel). Much more along those lines is to follow as she begins her stint as a post doc in the lab to finish up work and publish the remaining studies based on her thesis work. For the time being, well-deserved vacation and the holidays loom. As of January 2014: Welcome, Dr. Kamimae -Lannning. (on the pic: Ashley and Peter - proud and relieved)

Kelsie Storm is the 2013 Neerhout Fellow
Dr. Robert Neerhout is counted among Oregon’s legendary Pediatricians. Not many of us had the privilege of working with him, but Dr. Larry Wolff, who counts Dr. Neerhout among his mentors, reminds us annually during his introductory remarks at the award presentations how high the bar was set for all-around excellence in Pediatrics at Doernbecher. And even in a competitive group of peers, it comes as only a small surprise that Kelsie who joined us in July is this year’s Neerhout Fellow. This is a remarkable vote of confidence for Kelsie who in accepting the award noted her gratitude to Dr. Susan Lindemulder and Dr. Linda Stork (Neerhout Professor of Pediatrics) - her clinical mentors.
To top off a spectacular week, her review article on hematopoietic stem cell expansion appeared in “The Hematologist”.
We could not be prouder! The picture? Digging clams; in style!
July 17, 2013
Jianya wanted to check out the ziplines in the Gorge, Noah prefers rock-climbing, but everyone agreed on the picnic. So we decided to spend our retreat at the Coast: Clamming in Netarts Bay.
We were joined by Forest and Katy, the hardest working students on campus and spent the day digging in the sand. In the process we seem to have collected all the shellfish that our licenses would allow. Strategies for success differed in interesting ways, as Kelsie teamed up with Forrest for what can only be described as an “open pit” strategy, whereas Katy insisted on a more organic approach using only her hands. Much the same can be said for our picnic where levels of preparedness ranged from chicken for the grill to a multi-pot assembly to steam the clams (Strong leadership, Shelton!).
If ever you find yourself ready to clam and without equipment: Kelsie learned that they rent shovels at the marina (who would have thought you can rent one??).
Great weather, great group and GREAT fun. What to do next year???

Friends of Doernbecher Grant Awarded !
We received welcome support for our gene therapy researchOnce a year the Friends of Doernbecher solicit grant proposals from pediatric researchers across OHSU. For many years these seed grants have provided crucial support and start up funds to develop new ideas and generate preliminary data for NIH grants. For 2013, the Friends decided to substantially increase their total funding. Good news! After all was said and done (21 applicants and six finalists who presented to a review panel) we were fortunate enough to be among the lucky four recipients for this year’s awards.
This generous support ($60,000) will help fund our gene therapy project as we develop non-integrating lentiviral vectors for bone marrow stem cell therapies. We are grateful to the Friends and all those that helped to make it happen. Congratulations Santhosh and Natalya. Your hard work and dedication paid off !

9th Annual Fanconi Anemia Run/Walk
Another year's run for a great cause
In a bit of a Valentine's Weekend tradition we enjoyed unseasonably dry and sunny weather for the 9th Annual Valentine's day Run/ Walk. Hundreds came, bringing awareness and energy to the Portland Waterfront, complete with bagels, hot chocolate and some funny costumes. Meeting friends and bringing families all for a great causes: FA research. Not to be missed the transformation of the course from gravel, mud and puddles to the beginnings of the OHSU waterfront campus and the new OSU Life Sciences building. Natalya organized and captained a team this year, with family to boot.

Amy completed her post-doctoral training ! With a laundry list of accomplishments and after 6 years of hard work Amy is moving on. During that time, she hit all the highlights one would hope for: First author publications, 4; authorships total, 9; training grants, 3; travel grants, 2; conference sites travelled to: Seattle, San Diego, Boston, New Orleans, Atlanta, San Francisco,… Interns trained, …lost count;. Amy directed the Department of Pediatrics Internship Program for 5 years from its inception and her skills and can-do attitude will be sorely missed around here.
Fortunately, she is not moving too far, taking a position as Lecturer in the Department of Surgery at OHSU where she will work with SueEllen Pommier.
May we have predicted her success? Apparently her cousin did in having her lab coat embroidered- 6 years ago: Super Star!

Annual scientific meeting of the Fanconi Anemia research fund
Once a year the FA research fund convenes their scientific meeting and this year we travelled to Denver. With over 200 international participants the meeting was as well attended as ever. The schedule was packed with educational opportunities from Thursday to Sunday morning. Particular highlights were the very encouraging updates on the stem cell transplantation experience and a scientific session on different methods of stem cell expansion. A new format was the point- counterpoint session featuring discussants addressing pros and cons of androgen use as well as radiation containing conditioning regimen for transplantation.
My favorite; a session devoted to the etiology of bone marrow failure with further evidence for a developmentally programmed, in utero onset.
Alas, no gene therapy this year!

Summer - internship time
We have had laboratory interns for most of the past summers and will host three this year. Nothing like inquisitive young minds to push research forward. No slackers here.
Kyle Lenz decided to rejoin us after his experience last spring when he spent his spring academic quarter in the lab. He just completed his sophomore year at Dartmouth and will work with Jianya and Noah on the leukemia vesicle project.
Karen Huan just graduated from the IB program at Southridge High School. She has been working with us as a part time lab aide for the past 6 months and decided to work on a project with Amy and Santhosh before heading off to Williams College.
Basma Saadoun is one of this year’s OSLER TL-1 Summer research Award recipients. She will pursue studies funded through the program to study the effects of high fat diet on the developmental programming of hematopoietic function. This project is in conjunction with the laboratory of Dan Marks. All three will pursue their research

Natalya's poster at OHSU Rare Disease Day 2012
Natalya joined us last fall and has been working hard with Ashley on the Fanconi Anmeia-Fetal Hematopoiesis project. Tasked with carrying on protein array work, but also setting up PCR studies on fetal liver expression of key hematopoiesis regulators, she made several important observations. We were all excited to help her prepare a poster including her data and the first ever OHSU Rare Disease Research Day was a great venue to present those findings. Designed as session opener, the poster session was well attended and Natalya stood her ground to inquisitive questions. She will continue her work in developing an immunohistochemistry protocol for this project and has taken a lead in expanding our mouse colony. Many more presentations to come– and not just on leap day !
Check out program links and highlights of Rare Disease Research Day.

What to do on a rainy Sunday morning in Portland in February ?
The 8th Annual Valentine Day Run is a pretty good place to start. Twelve hundred believers in FA research showed up and $46,000 were raised. OHSU had a strong presence and it was fun to see friends and community come together to support the cause.
Ashley’s third year (I think) and eight for me. We will have to work on growing the team and upgrade on our gear. Not much a fan of bee costumes (I counted three runners in those), maybe it’s time to get personalized hoodies, like Maureen.
December 6, 2011Still unpacking boxes from his move to Portland, Santhosh C. Verghese joined us this week. He brings experience and critical expertise in retrovirology and vector design to the lab. Santhosh and his wife and son relocated from the Washington DC area, where he most recently worked at the NIH. Santosh has already been counseled not to take the current Portland sunshine for granted. Word on the street is, Santhosh has plans to rediscover his bike legs. Welcome!
October 10, 2011
Exciting news this last week as Ashley, Noah and Michael had their abstract submissions accepted for presentation at the December Annual Meeting of the American Society of Hematology. Along with co-authors, they worked hard over the summer months to complete (...and repeat, and repeat...) their experiments.
- Ashley N. Kamimae-Lanning, Tae Hoon Ha, Amy M. Skinner, Thomas B. Russell, Peter Kurre Developmental defects in hematopoiesis in a mouse model of Fanconi Anemia.
- Noah Hornick, Jianya Huan, Jeffrey W. Tyner and Peter Kurre. Flt3 Kinase Regulates Microvesicle Transfer of miRNA Between AML and Stromal Cell.
- Michael Layoun, Amy M. Skinner, Jianya Huan, Peter Kurre. Exosome trafficking of BCR-ABL oncoprotein promotes the IL-3 independent proliferation of bystander cells.
All three will be busy preparing their presentations of the next few weeks and we are looking forward to attending the meeting in San Diego.
Much deserved recognition and a sun break in the upcoming rain season!
July 25, 2011
With several people having recently joined, we decided to take some time away and have a lab retreat visiting Ape Cave and Lava Canyon on the slopes of Mount St. Helens. Rewarded by sunshine and just enough clouds to enhance Jianya's photos we took a guided tour of the Lavatubes. Amy turned out to be a skilled naturalist and promptly spotted the elusive gyrlloblattid (below) in the cave. (Proposed as the new lab mascot by Thomas). Noah brought no fewer than 6 lights only to find that most of them had exhausted batteries. Michael had hoped for some serious spelunking, but left the cave without any lost treasures.
After more than an hour in the cave at 42 F, we were ready for our picnic, greatly enhanced by Lauriel's Mojito's and A LOT of food. Finally a hike through the Lava Canyon and Ashley's cupcakes to complete the day! Lots of fun.
Joining us for the summer - and on this trip - were Lauriel, incoming PMCB student, Michael Layoun (MS1) and Tae Ha (MS2)
June 8, 2011We recently welcomed Jianya Huan PhD to the team. Jianya brings extensive experience in Molecular Biology and Protein Biochemistry to the group and will help us expand our research in microvesicle biology. He received his PhD from Oregon State University and was s a long -term member of the OHSU Neurology Department - Multiple Sclerosis Study Group. Jianya will provide us with valuable research expertise in immunology and serve as a great teacher to others.

¡ Hola Ashley !
Ashley just received word that she was named a 2011 Tartar Trust Fellow. The award will allow her to present her research project at the annual Fanconi Anemia (FA) Research Conference. A US-based conference in most years, except when the organizers decided to hold this year’s event in Barcelona, Spain.
Ashley has worked hard on her experiments understanding the developmental origins of bone marrow failure in the Fancc mouse model. Her work highlights a resurgent interest in the developmental hematopoiesis in the FA field as part of an effort to gain a more fundamental understanding of FA biology. Knowing more about the onset of hematopoietic failure and to what extent stem cell exhaustion is of pre-natal origin will have implications for diagnosis and perhaps treatment. It would also provide a much-needed perspective to complement research into induced pluripotent FA patient stem cells.
As for her Barcelona presentation..., it looks like she will have plenty of practice opportunity this week and next. She will be giving oral presentations at the student research forum and also at the Cell & Developmental Biology departmental seminars, respectively.
What a week. Well-deserved recognition of her dedicated work in the lab and the prospect of some exciting travel coming up this October.

Less is more
Who would have thought what effort it takes to get rid of a little oxygen!
Oxygen partial pressures in most tissues are well below ambient conditions and those commonly used in tissue culture incubators. This has long been recognized as a limitation to cancer and hematopoiesis research. Hypoxia is also a key feature of the hematopoietic niche and plays a principal role in maintaining the stem cell pool. Hypoxia in the tumor microenvironment helps promote tumor vascularization and leukemogenesis is intricately linked to low oxygen in the bone marrow. Even Fanconi anemia progenitors show improved colony formation in low oxygen conditions.
Sounds like a great resource for our research program ? We certainly think that the ability to culture and (with some funding for a microscope…) seamlessly analyze cells under these conditions will substantially enhance our research program capability and provide new insight in stem cell and cancer biology.
The hypoxia chamber will be available to OHSU stem cell center and pediatric research faculty as a shared resource.
While we are finishing the final install and look forward to taking the chamber into operation, we want to thank Qianyue Wang and J-B Roullet, PhD, for their help getting this awesome piece of equipment up and running.

Welcome Kyle !
Kyle Lenz has joined the lab for a spring semester internship. Kyle is a native of Salem, Oregon and graduated as valedictorian of his class from West Salem High School. He subsequently enrolled at Dartmouth College in New Hampshire where he is currently finishing his sophomore year.
Kyle has a long standing interest in science and is participating in the Howard Hughes Undergraduate Training Program at Dartmouth where he works in the lab of Dr. Jay Dunlap and Dr. Jennifer Loros. Over the past year he has conducted research on the effects of DNA damage on the mammalian cell and the role it plays in the circadian rhythm of an organism through a mouse embryonic fibroblast model. Kyle plans to continue this work in the Dunlap/Loros Lab over the course of the next year, before eventually writing a thesis. While here, Kyle will participate in work on understanding intrahematopoietic cell fusion. He will specifically work on developing high resolution melting temperature PCR protocols for SNP analysis in cell fusion products and will look for lineage ambiguity in cells from transplant recipients.
We are excited to have Kyle join the lab and look forward some exciting science !

Happy St. Patrick’s day!
The St. Baldrick’s Foundation has awarded a St. Baldrick’s Summer Fellowship grant to the OHSU Department of Pediatrics Summer Internship Program
For the past 4 years Amy Skinner, Ph.D. has directed this Internship program to foster science education at OHSU by matching undergraduate and highschool interns with Pediatric Faculty Mentors for a summer research experience. Under her guidance, the 10-week summer program promotes science through faculty seminars, workshops, journal clubs and peer group networking.
Always on the lookout for ways to further enhance the program, Amy initiated an institutional application to the St. Baldricks Foundation, championed by Department Chair H. Stacy Nicholson, M.D., MPH. Now Doernbecher will join a group of six elite Children’s Hospitals in the nation that currently receive the award Duke, Columbia, Rainbow and Babies in Cleveland, among them. The generous $5,000 fellowship grant will specifically support medical students working on pediatric oncology research the summer between the first and second year of medical school. This grant allows for a summer fellow stipend and expenses.
Training the next generation to make a difference!!
February 24, 2011
Congratulations Amy !
The OHSU Knight Cancer Institute and U.S. Bank have awarded the 2011 US Bank Cancer Research Development Award to Amy Skinner.
The annual award recognizes promising young OHSU investigators and supports their important work in cancer research. In selecting Amy from a field of uniquely talented colleagues, the Award Committee recognized Amy’s talent, drive and commitment. Her project aims to understand the role of chromosomal changes in bone marrow cells and whether those changes are the earliest harbingers of cancer. The innovative work was conducted in close collaboration with the lab of W. H. Fleming and was presented in part at the 2010 Annual Meeting of the International Society for Stem Cell Research. Amy’s discussion of her important observations at the December 2010 Meeting of the American Society of Hematology (ASH) was subject of strong interest during the meeting and rewarded with an ASH Travel Award.
The US Bank Cancer Research Development Award was awarded during a luncheon with US Bank and OHSU Knight Cancer Institute leadership.

Annual Valentine's Day Fanconi Anemia Run/Walk
For the seventh year running Peg Padden has hosted the Fanconi Anemia (FA) Valentine's Run at the Portland Waterfront. This great grass roots community event is held annually to benefit research into causes and treatment of Fanconi Anemia, a rare inherited illness that results in the loss of blood forming cells and an increased risk of developing cancer. Testament to Peg's talent in motivating people, the event has grown to attract over 1000 participants this year and will contribute nearly $47,000 to the Fanconi Anemia Research Fund effort to help patients with this illness. As an added attraction the first -ever Adult FA patient meeting was held on the same weekend!
Joining FA patients, other researchers and friends, Ashley, Peter and their families helped spread the word. Ashley has actively researched the roots of bone marrow failure and stem cell loss in this disease as part of her PhD thesis project. She and Jared were repeat participants and completed the 12k walk. Peter and family took the 5k shortcut.
