Research Interests

Our laboratory is focused on the transcriptional regulation of estrogen receptor (ER) signaling pathways by nuclear receptor co-factors. Our major interest is on a protein arginine (R) methyltransferase CARM1/PRMT4, a nuclear hormone receptor co-activator. Histone H3 methylation by CARM1 potentiates target gene activation by ER.

Our ongoing studies include combining biochemical and functional genomic approaches to understand ER-regulated processes controlled by CARM1 and the mechanism by which histone arginine modification contributes to the epigenetic control of cancer cells.

We will also employ mice genetics to decipher the significance of histone arginine methylation in tumor prevention, thereby facilitating the rational design of novel chemotherapy drugs by targeting the epigenome in breast cancer.
