Research Summary

The efforts of this laboratory are directed toward the understanding genetic and epigenetic aspects of cervical cancer and hematologic malignancies. One of the major goals is to make attempts to identify prognostic markers of response to treatment.

Carcinoma of uterine cervix is a common malignancy among women worldwide. Most cervical cancers are preceded by distinct preneoplastic epithelial changes, which progress to invasive cancer, thus providing opportunities to study genetic alterations at an early stage of transformation. In a genome-wide search for genetic alterations, we have identified several sites of copy number alterations, gene amplifications, and specific genetic pathways in invasive cancer. We are currently evaluating a predictive biomarker of apoptotic response to stratify patients that benefit combination drug therapy.

In leukemia and lymphoma, a similar strategy is applied to identify genetic and epigenetic predictive markers of response to treatment. Preclinical validations of a number of epigenetically inactivated markers are underway.

Service Activities

Cytogenetic and molecular cytogenetic testing of hematologic and solid malignancies.
