Amanda d'Almeida

Research Assistant II

Education: Bachelor of Arts in Chemistry, Carleton College, Northfield, MN

Scientific interests: I am interested in the intersection of research and clinical practice, prevalent in the Tyner Lab. I assist in processing patient samples for BeatAML and run drug panels to help identify potential treatments for clinical trial patients. Additionally, I am part of a small group implementing the CRISPR/Cas system into the lab in order to identify essential genes in AML and CLL patient samples.

Postdoctoral Researcher

Education: B.Sc. Biology, Mahidol University; Ph.D. Cancer Biology, University of Wisconsin-Madison

Scientific Interests: AML is a disease with highly heterogeneity of genetic lesions. Targeted therapy using small molecule inhibitors is an important factor toward precision medicine for patients with AML. Several targeted therapeutic drugs have shown promising results on patients who have AML. However, most patients relapse due to the development of drug resistance. Understanding how AML cells gain resistance toward small molecule inhibitors is necessary and critical to improve the treatment regimen for those patients. I am interested in elucidating the mechanism of drug resistance in AML, which can lead to possible approaches to prevent or overcome the cells become drug resistant. I am part of the research group studying the mechanism of drug resistance toward diverse types of small molecule inhibitors in AML by utilizing CRISPR genome wide screening.

Education: M.S.(in progress), Institute of Environmental Health and Division of Environmental and Biomolecular Systems, Biochemistry and Molecular Biology Track, Oregon Health and Science University; B.S., Molecular Biology and Genetics, Istanbul University, Istanbul.

Scientific Interests: My main research interest is functional studies on cellular signaling pathways, particularly tyrosine kinases. In order to understand their activation mechanisms and abnormalities in those, I study most frequent kinase vulnerabilities which we have detected in patient samples in cancer cell line models by silencing/inhibition kinases. I mostly use BeatAML data for that purpose. For analyzing and visualizing this valuable data-set, improving my skills on bioinformatics and computational genomics is also one of my research goals.

Scientific interests: Acute Myeloblastic Leukemia (AML) is a devastating disorder, predominantly in older adults, more rarely in children and young adults. Enormous progress has been made in treatment of this disorder using a personalized medicine approach developed in the laboratories  of Drs. Brian Druker and Jeff Tyner. But it still remains a disease with often short remission, especially for older patients. For these AML patients, new, highly effective drugs are being constantly developed. But unfortunately, emerging drug resistance is a major obstacle for new drugs to continue being effective after initial short-lived success. The future of AML treatment lies in combination therapies that can counteract the potential resistances by preventing or delaying drug de-sensitization. My main interest is to investigate mechanisms of drug resistances establishing a way for new combinatorial treatments, using genome wide CRISPR Cas9 approaches in a variety of genomic landscapes represented by patient derived cell lines and/or primary patient cells. When I am not in the lab, I am involved too much in my kids' education and activities all around Portland, and dreaming of a long and lazy vacation when I am walking my dog.

Research Assistant II

Education: Bachelors of Science in Cell and Molecular Biology, George Fox University 

Scientific Interests: I enjoy the convergence of scientific research and patient treatment. Being able to see lab work transition or translate into the clinic gives our work a deeper and personal purpose. It is so fascinating how we can discover single mutations in the lab in a patient’s genome, characterize and classify using common functional validation assays, identify a target/treatment and observe patient response through our ongoing clinical trials. It is truly an incredible and meaningful process.

Education: A.S, Columbia Basin Community College; B.S Biochemistry and Molecular Biology, Washington State University

Scientific Interests: I am interested in characterizing the tumor microenvironment of AML when treated with immune checkpoint blockade and small molecule inhibitors that have shown to have synergistic affects. A focus of my project is using epigenetic modifying small molecules, such as bromodomain inhibitors, and how they may bolster the anti-tumor response of patient healthy t-cells. I am further trying to determine mechanisms of acquired resistance to small molecule inhibitors and how we can circumvent them.

Scientific Interests: Our group is interested in identifying tumorigenic genetic lesions and exploring targeted therapies for each leukemia patient. I am particularly keen to elucidate the detailed underlying transformation mechanisms, namely the genetic mutations-aberrant signaling pathways-deregulated microRNAs/mRNAs circuits, each member of which might be a potential therapeutic target. A better understanding of this oncogenic network may allow us to develop multiple single or combined therapeutics which are more effective, more sensitive and may circumvent drug resistance. For this purpose, thorough genetic sequencing is used to identify specific genetic lesions followed by in vitro functional screening with libraries of siRNAs and small molecule inhibitors to unravel and verify the potential oncogenic circuits. Meanwhile, in vitro and in vivo validation studies are performed to select and optimize the potential therapeutics. These validation strategies include biochemical analyses to elucidate signaling crosstalk mechanisms. With these studies, we cumulatively aim to establish individually tailored therapy for cancer patients. Currently, I’m working on crenolanib resistance mechanisms based on exome sequencing analysis. In addition, we are characterizing the function and leukemogenic mechanisms of CSF3R cytoplasmic domain mutations in a variety of hematological malignances.

Lab Alumni

Marilynn Chow


Education: Ph.D. in Cancer Biology, Oregon Health & Science University; B.S., Molecular, Cellular and Developmental Biology, University of California, Santa Cruz; M.S.; Biology, University of the Pacific.

Scientific Interests: My Ph.D. thesis research focuses on elucidating the upstream regulatory and downstream signaling mechanisms of ROR1, a pseudokinase that is required for the survival of a subset of pre B-cell acute lymphoblastic leukemias. This project allows me to expand my prior skillset in molecular and cellular biology and more importantly, address an increasing demand to better understand the essential biology that drives leukemia and other types of cancer. When I am away from the lab I enjoy trying new restaurants, baking, running, and binge-watching Netflix and Hulu.
