We have been using cell biological, molecular biological and genetic approaches to understand mechanisms underlying disease processes and to identify gene targets for therapeutic interventions. We have applied these approaches toward investigating breast, prostate and ovarian cancer, diabetic retinopathy, and genetic deafness. The following is a brief description of some of our current research topics and past projects.

1. Epigenetic mechanisms of breast cancer invasiveness: We have profiled the expression of Eph receptors, the largest family of receptor tyrosine kinases, and their ephrin ligands in breast carcinoma cells. We are exploring epigenetic mechanisms responsible for transcriptional regulation of specific receptors/ligands receptor in invasive breast carcinoma cells, and characterizing interactions among Eph receptors, and between Eph receptors and cadherins. In addition, we are developing methylation sensitive PCR (MSP) assays of gene promoters as diagnostic tools to determine estrogen-positive and estrogen-negative cells in breast tumors.
2. Breast cancer stem cells: We have characterized stem cells from cell lines representing normal breast cell line, and noninvasive breast cancer and invasive breast carcinoma cell lines. We are investigating interactions of Eph receptors and ephrin ligands of stem cells with bulk tumor cells and stroma to determine/predict potential phenotype and progression. The effects of known therapeutic agents on stem cells is also being investigated.
3. Inactivation of senescence causing genes in human cancers: In a collaborative study, we have characterized transcriptional regulation of transcript variants of ionotropic glutamate receptor GluR6/GRIK2. We are exploring differential expression of this gene in neuronal and non-neuronal cells to determine biological significance of GluR6 transcriptional silencing and inhibition of the senescence program in cancer cell lines.
4. Molecular basis of diabetic retinopathy: In collaboration with investigators at the National Eye Institute, we have characterized transcript profiles of normal and diabetic retina by RNA-seq strategy. Similar approach has been utilized for miRNA profiling.
5. Human deafness: Genetic or acquired deafness is a major public health concern. Many nonsyndromic hearing loss phenotypes have been mapped to various human chromosomes. We have characterized cDNA libraries from human inner ear for applying cDNA selection strategies to map inner ear specific cDNAs to regions of human chromosomes harboring deafness loci.
