Iva Tchasovnikarova, PhD

Dr. Tchasovnikarova is investigating the role of chromatin remodeling in epigenetic gene silencing by the recently discovered HUSH complex. Her research aims to delineate how heterochromatin formation is achieved through the concerted action of heterochromatin-associated proteins, heterochromatic histone modifications, and ATP-driven chromatin remodeling. As heterochromatin formation has been shown to be associated with oncogenic events, her future work will define general principles that could be exploited to design cancer therapies aimed at heterochromatin dysregulation.

Albert Tsai, PhD

Dr. Tsai is studying a process called translation, by which messenger RNAs (mRNAs) are decoded into proteins. A hallmark of cancer cells is distorted patterns of protein production, leading to uncontrolled growth and invasive behavior. He is using novel microscope technology to image live cells in real-time and developing techniques to image individual protein molecules during their synthesis, thereby linking the time, location and amount of protein production to individual mRNAs. He will first examine these processes in bone cancer-derived cell lines. He will also examine how neurons control translation of structural proteins in the precise location where the neuron is stimulated, which underlies memory formation and learning. Ultimately, this work will contribute toward a precise and predictive model for translational control that explains how cancer cells circumvent control mechanisms.

Neil T. Umbreit, PhD

Dr. Umbreit [HHMI Fellow] studies chromosome segregation, the process by which the genetic information on chromosomes is duplicated and the copies are segregated equally into two new cells. Cancer cell proliferation is marked by frequent errors in chromosome segregation, resulting in abnormal genetic content in the progeny. He is investigating one type of chromosome segregation error, called a “chromosome bridge,” a major mechanism through which genetic information can be amplified and/or rearranged to distort gene function in cancer cells. When these genetic rearrangements include oncogenes and growth factor genes, they can result in acquired drug resistance, unrestrained cell proliferation, and metastasis. Identifying and understanding the pathways that give rise to these alterations is critical, as they represent cancer-specific targets that can be exploited to develop effective therapeutics.

Eliezer M. Van Allen, MD

Many cancers are treated with chemotherapies that affect DNA repair, such as platinum chemotherapy, and some patients derive significant benefit from these agents. However, the underlying genomic features that drive selective response to these treatments is incompletely characterized. Dr. Van Allen aims to blend precision cancer medicine principles with DNA repair treatments and enhance cancer care. He will do so by studying the genomics of response to existing and emerging DNA repair therapies in preclinical models as well as patients across different tumor types.

Thomas S. Vierbuchen, PhD

Dr. Vierbuchen [HHMI Fellow] aims to understand how neurons adapt to experience by modifying the complement of genes they express. He is using high-throughput sequencing-based approaches to identify and characterize the function of genomic regulatory elements that control neuronal activity-regulated gene transcription.

Linda T. Vo, PhD

Dr. Vo focuses on T cell-based cancer immunotherapy, such as chimeric antigen receptor “CAR” T cells, as a transformative therapeutic approach. While recent studies have demonstrated the efficacy of CAR-T cell therapy in treating certain leukemias and lymphomas, further advancements are required to broaden its therapeutic utility. Pluripotent stem cells (PSCs) have the capacity to generate any cell type of the body and represent a potentially inexhaustible source of clinically useful cells. Using a novel strategy to promote the continuous generation of T cell progenitors from PSCs, she will engineer “off-the-shelf” T cells with improved tumor-recognition capability from stem cells. The successful generation of potent, dual-antigen specific T cells from PSCs in large quantities as an off-the-shelf product would be invaluable to the widespread application of T cell-based immunotherapies.

Jakob von Moltke, PhD

Immunotherapies that take the brakes off the immune response and direct cytotoxic T lymphocytes (CTLs) to hunt down tumors have revolutionized cancer treatment in the last decade. Stories of patients who are cured by immunotherapy even after exhausting all other treatment options are increasingly common – but unfortunately, only a minority of patients achieve such remarkable benefits. Now, two pressing challenges are to understand why immunotherapy fails in non-responders and to develop new or modified therapies that achieve durable remission for these patients as well. Successful immunotherapy is predicated on the infiltration of the tumor microenvironment by tumor-specific CTLs. The cells and signals that generate and sustain these cells are collectively known as type 1 immunity. Conversly, the immune cells and signals associated with the distinct processes of tissue remodeling and wound healing are known as type 2 immunity. At best, a tumor microenvironment dominated by a type 2 immune response precludes a robust type 1 response, but there is also evidence that the type 2 response may actually promote tumor growth and survival. The success of cancer immunotherapy may therefore rely in part on preventing type 2 responses. The goal of this work is to understand the regulation of type 2 immune responses, with a particular focus on the earliest events that lead to initiation of type 2 immunity. It is our hope that insights gained from these studies will inform that development of improved cancer immunotherapies that guide immune responses away from type 2 towards type 1.

Victoria E.H. Wang, MD, PhD

Dr. Wang seeks to understand the mechanisms by which tumor cells become resistant to drug therapy and spread to distant organs. She is utilizing functional genomics tools to identify novel pathways modulating these processes in the hope of developing new therapies to augment treatment response in cancer patients.

Lan Wang, PhD

Dr. Wang studies tailed-anchored proteins, a class of membrane proteins that perform important physiological functions. Cells possess machinery that ensures the correct distribution of tail-anchored proteins to their specific organelle. Her research aims to understand how cells accurately distribute the tail-anchored proteins amongst their multiple organelles and what happens when such mechanisms fail.

Kurt J. Warnhoff, PhD

Dr. Warnhoff is studying how the timing of developmental events is regulated at the genetic level. Importantly, failures in normal developmental biology often give rise to cancer. microRNAs (miRNAs) are a class of key regulators of developmental timing. These small RNA molecules regulate gene expression, developmental transitions, metabolism, cell fate, and cell death. His research will examine new genes and pathways that modify miRNA biogenesis and activity to affect these critical developmental processes.
