Research Interests

Our laboratory is interested in studying the changes induced, with an emphasis on wnt signal transduction pathway, during the initiation and progression of colon and breast cancer. wnt deregulators are identified by molecular and in vitro cell culture methods and their role in both induction and progression of early lesions are tested by generating transgenic murine models. These models could also serve as an in vivo drug validation and testing models of colorectal neoplasia. Another project of interest in our laboratory is to look at the role of microRNAs (oncomiRs) in the development of colon and breast cancer. OncomiRs, a special class of non-coding microRNAs are found to be associated with a large number of cancers. We have developed a microRNA database for breast and colon cancer and experimentally tested these on different microarray platforms. Impaired microRNA signatures are noticed in different stages and grades of these tumours. We are further characterizing the microRNA targets for developing into functional biomarkers.
