Neil Vasan Lab

Laboratory of Functional Cancer Genomics

Herbert Irving Comprehensive Cancer Center

Columbia University

We study how kinases regulate 

breast cancer growth and drug response.

Kinases control nearly all aspects of human biology 

and are the largest druggable protein class in cancer.

We manipulate kinases using next-generation functional genomics tools 

and study these effects using cell biology, biochemistry, and proteomics.

Our goal is to apply these findings to discover new drug targets to prolong the lives of breast cancer patients.

Research

Turning off kinases to accelerate cancer drug discovery

Kinases are one of the most important targets in precision oncology, but the ideal kinase targets for most cancers have not been established. Determining the cellular consequences of turning off kinases has immense potential to transform our understanding of kinases and kinase inhibitors. We are deciphering how kinases regulate cancer cell function by using genome editing to turn off the activity of every kinase in the human genome. This approach will identify novel kinases for therapeutic targeting and will act as a surrogate for small-molecule inhibition to enable drug discovery. We will use this platform to interrogate how kinase activity regulates breast cancer cell growth, sensitivity to targeted therapies, and druggable gene expression. This will compress the interval between kinase hit and lead discovery from decades to years by identifying the optimal mechanisms to inhibit kinases, transforming drug development and the design of combination therapies. 

Solving the PI3K mutational code to tailor PI3K inhibition in breast cancer

PIK3CA is the most frequently mutated oncogene in human cancer and PI3K inhibitors are a standard of care therapy in PIK3CA mutant breast cancer. However, in most patients, it is unknown which PI3K mutations are activating and/or drug-sensitizing. We have previously characterized double mutations in PI3K which hyperactivate PI3K resulting in increased PI3K inhibitor sensitivity (Vasan et al. Science 2019, Sivakumar...Sokol, Vasan Clin Cancer Res 2023). We now will comprehensively characterize PI3K protein variants using deep mutational scanning and structural biology. This work will define the repertoire of activating and drug-sensitive patient mutations and will guide the development of mutant-selective PI3K inhibitors.

Discovering and targeting new phosphoprotein drivers of cancer

Functional genomics has identified numerous genetic drivers of cancer, giving rise to a new generation of targeted therapies. While proteins are the primary functional machinery in cells, the vast majority of modified proteins---including phosphoproteins---lack a known kinase or biological function. We aim to illuminate this “dark phosphoproteome” by finding novel substrates of kinases using phosphoproteomics and validating frequent phosphoproteins in cancer. To this end, we have already discovered new frequently phosphorylated substrates including phosphatases, epigenetic modifiers, and metabolic enzymes, which we will functionally characterize to elucidate novel targetable phosphoprotein drivers of cancer.

Identifying and validating new biomarkers of drug resistance in breast cancer

The response to anticancer therapies is limited by drug resistance (Vasan et al. Nature 2019). Traditional approaches to investigate drug resistance use targeted gene sequencing panels which are limited and do not include many critical genes that regulate major cancer cell signaling pathways. We are performing unbiased whole exome and transcriptome sequencing of tumors from patients receiving breast cancer targeted therapies and chemotherapies, in collaboration with our clinical colleagues. This will nominate new biomarkers of therapeutic resistance and we will test these mechanisms which in the laboratory. This work will determine who does–-and does not—benefit from breast cancer therapies.

Neil Vasan, MD, PhD

Neil is a physician scientist and Assistant Professor of Medicine in the Division of Hematology and Oncology and the Herbert Irving Comprehensive Cancer Center at Columbia University Irving Medical Center. He received his AB/AM from Harvard University and MD/PhD from Yale University School of Medicine, and completed clinical training in internal medicine at Massachusetts General Hospital and in medical oncology at Memorial Sloan Kettering Cancer Center. As a postdoctoral fellow, he identified double PIK3CA mutations as an oncogenic alteration, which has gone from bench to bedside as a cancer genomic biomarker. His research awards include the NIH Director's New Innovator Award (DP2), NCI Mentored Clinical Scientist Development Award (K08), AACR NextGen Star, and ASCI Young Physician-Scientist Award. He has also received research funding from Susan G. Komen, Breast Cancer Alliance, and Gilead. Neil is an active clinical oncologist treating patients with breast cancer, and serves as the Scientific Advisor for the PIK3CA Pathbreakers patient advocacy group, and as a standing member of the Oncologic Drugs Advisory Committee (ODAC) for the FDA.

Postdoctoral Fellows

Hanna Karvonen, PhD

Recipient of EMBO Postdoctoral Fellowship

 

Hanna received her PhD in cell and molecular biology from Tampere University, Finland, in the lab of Daniela Ungureanu where she studied the role of ROR1 pseudokinase signaling in B-cell malignancies and ovarian cancer and aimed to identify drugs that could work in combination with ROR1-targeted cancer therapies. In the Vasan lab, her research focuses on understanding how kinases regulate cancer cell growth using genome editing screens.

Remkes Scheele, PhD


Remkes Scheele obtained his BSc in Life Science and Technology from the University of Groningen. During his MSc, he performed graduate internships in the laboratories of Gerard Roelfes and Frances Arnold on artificial metalloenzymes and tryptophan synthase evolution, respectively. Remkes went on to complete his PhD in droplet microfluidics in the Hollfelder group at the University of Cambridge. Currently, Remkes is involved in genome editing screens to uncover vulnerabilities for cancer therapeutics.

Laboratory Technician and Manager

Ruchita Rathod, MS

Ruchita received her master's degree in Pharmaceutical Sciences from St. John’s University, New York, USA. She worked on the Bone Morphogenic Protein (BMP) signaling pathway. She then worked at the Memorial Sloan Kettering Cancer Center and Weill Cornell in Dr. Lewis Cantley’s lab as a research assistant assisting Dr. Neil Vasan in investigating genetic heterogeneity in tumors with PIK3CA mutations.

Fun fact: I enjoy relieving stress through cooking and baking. I love dancing to Bollywood music.
