Profile Introduction

The research in the Knoepfler lab focuses on the epigenetic and transcriptional control mechanisms that direct stem cell cell fate and tissue growth. We are particularly interested in the relationship and epigenomic ties between tumorigenicity and pluripotency. How are normal stem cells programmed and how does this programming go awry in cancer? Our cancer focus is predominantly on pediatric nervous system tumors. Our model systems including both mouse and human ESC, induced pluripotent stem (iPS) cells, and cancer stem cells. Our two big picture goals are to make innovative cancer treatments (particularly for childhood nervous system tumors) and to make stem cell-based regenerative medicine therapies more effective as well as safer with lower risk of tumorigenesis.

Research Interests

Stem cell and cancer epigenomics

Our lab's main research interest is focused on epigenomic control of stem and cancer cell behavior. We are particularly interested in three types of regulatory factors: MYC proteins, DPPA4/2, and the histone variant H3.3. Althought these proteins are not related to each other at the amino acid level, they share the same pattern of having key roles in normal stem cells and, when deregulated, in cancer. To study these factors we use a variety of methods including genetics, cell and molecular biology, genomics, protein biochemistry, and emerging gene editing technologies.
