Dr. Muthusamy Thangaraju (Raju) is a breast cancer research scientist. I started my research career as a breast cancer Scientist in 1991 when I was a graduate student at the University of Madras, India. Then I moved to the McGill University, Montreal, Canada to do the post-doctoral fellowships where I studied the role of protein tyrosine phosphatases, SHP1 and SHP2, in breast cancer growth and progression. Then I joined the Mayo Clinic, Rochester, MN, and expanded my research in breast cancer and investigated the role of BRCA1 and BRCA2, the two breast cancer susceptibility genes, in the regulation of DNA damage repair and apoptosis in breast cancer. Then I joined the National Cancer Institute (NCI), Frederick, MD where I explored the functional implication of CCAAT/Enhancer Binding Protein delta (CEBPD) in mammary gland development and its relevance to mammary tumor growth and progression. Currently, I am an Associate Professor at the Augusta University and studying the role of epigenetics and regulation of mammary gland development and its association with mammary stem cells (MaSC) and breast cancer stem cell (BCSC) self-renewal.

Research Interests

Role of epigenetics, especially DNA methyltransferase 1 (DNMT1), in regulation of mammary stem and progenitor cells (MaSC) and breast cancer stem cell (BCSC) self-renewal and its association in breast cancer growth and progression.
The main focus of my laboratory is to understand the role of DNMT1 in regulation of MaSC and BCSC self-renewal and to explore the role histone deacetylases (HDACs) and histone methyltransferases (HMTs) in these cells. We are also interested in developing small molecules to target BCSCs by utilizing state of the art gene-targeting strategies and spontaneous mouse mammary tumor models.

We are also interested to understand the role of Epigenetics, especially DNMT1 and DNMT3b, in the cytogenesis of autosomal polycystic kidney disease (ADPKD).
