Research Summary

Cancer is a complex disease and typically involves multiple gene-specific and global genetic and epigenetic changes in human genome. The major class of genes that has been causally linked to the process of tumorigensis is tumor suppressors, which acts as a “breaks” and oncogenes, which functions as “accelerators” and typically promotes cancer. Recently, microRNAs are also linked to cancer wherein they can function either as tumor suppressors or oncogenes. The focus of our lab is to understand the mechanisms of genetic and epigenetic regulation of cancer causing genes and translating this understanding for early detection and treatment of human cancers.
