We have been using cell biological, molecular biological and genetic approaches to understand mechanisms underlying disease processes and indentifying targets for therapeutic interventions. We have been applying these approaches toward investigating breast, prostate and ovarian cancer, diabetic retinopathy, and genetic deafness. The following is a brief description of some projects currently underway or proposed projects in my laboratory.
- 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 currently exploring epigenetic mechanisms responsible for the loss of EphB6 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) assay of EphB6 promoter as a diagnostic tool to determine estrogen-positive and estrogen-negative cells in breast tumors. Another aspect of our research is aimed at determining the transcriptomic profiles of cancer stem cells isolated from breast carcinoma cells of varying degress of invasivness.
- Molecular basis of diabetic retinopathy: In collaboration with investigators in the Neurobiology, Neurodegeneration and Repair Laboratory (NNRL) at the National Eye Institute, we have recently embarked on investigating the mRNA, miRNA, proteomic and mitochondrial bioenergietic profiles of normal and diabetic retina. The objective of these studies is to unravel the molecular consequences of diabetes in photoreceptor cells in the retina.
- Candidate genes involved in human deafness: Human deafness, genetic or acquired, is a major public health concern. A large number of nonsyndromic hearing loss phenotypes have been mapped to various loci on human chromosomes. We have used in silico approaches to catalog a list of candidate genes from chromosome regions linked to deafness phenotypes. We propose to characterize selected candidate cDNAs for their potential involvement in inner ear function.
