Tumorigenesis Archives - Sanford Burnham Prebys

Kevin Tharp studies the interplay between mitochondrial metabolism and the physical properties of the tumor microenvironment, using genetically engineered mouse models and bioengineered human tumor models to define the mitochondrial programming unique to cancer cells in the tumor microenvironment.

His goal is to develop new therapies that block the metabolic adaptations that cancer cells use to metastasize, a major cause of cancer-associated mortality.

“I study how cells make decisions about their metabolic programming, which I expect will enable us to develop new therapeutics against metastatic tumor cells.”

Tharp previously worked as a postdoctoral scholar in the Center for Bioengineering & Tissue Regeneration at UCSF Health.

He completed his PhD in metabolic biology at UC Berkeley and his Bachelor of Science degree in biochemistry and molecular biology at UC Santa Cruz, where he graduated with honors and the Dean’s Award in Chemistry.

He has received meritorious funding awards from the Sandler Foundation and the National Institutes of Health/National Cancer Institute for his postdoctoral research.

Xueqin (Sherine) Sun seeks to better understand the genetic and epigenetic underpinnings of cancers, using genome editing technologies, animal and patient-derived models, and other tools to develop more effective cancer therapies.

“My lab is interested in studying how DNA or the machinery that interprets it leads to the transformation of normal cells into cancerous cells and concurrently, their specific vulnerabilities. Identifying these intrinsic vulnerabilities and targeting them properly is profoundly important to developing effective cancer therapies.”

Another aspect of Sun’s work is understanding how cancer cells and tumors change their circumstances and environment to improve survival, including hiding from or repressing the immune system.

“Changes to DNA itself and the way how DNA is interpreted by cells can transform normal cells into cancer cells. And transformed cells propagate by enhancing the misinterpreted DNA information, which in turn becomes the Achilles’ heel of cancer cells. Our goal is to find out how DNA information is misinterpreted in different ways and how to correct it to halt cancer.”

At Sanford Burnham Prebys, Sun and colleagues will employ a host of leading-edge tools and approaches, including functional genomics, artificial intelligence, structural biology, large-scale drug screening, and advanced imaging/spatial technologies.

Sun conducted her postdoctoral fellowship at Cold Spring Harbor Laboratory under the guidance of Alea Mills, PhD, a professor at the National Cancer Institute-designated cancer center at Cold Spring Harbor.

She received her PhD from Wuhan University in China.
