My laboratory is focused on deciphering the signaling pathways regulated by p63 and its role in cancer and development. p63 is a member of the p53 family member and has been shown to play a role in tumorigenesis, maintenance of epithelial stem cells and development. p63 has a complex genomic organization that results from alternate promoter usage and alternative splicing and is a homolog of the tumor suppressor protein p53. Unlike the p53 knockout mice which exhibit a high incidence of spontaneous tumors, the p63 knockout mice displays severe developmental abnormalities including limb truncations and craniofacial abnormalities. p63 mutations are also observed in various human developmental syndromes.
Our laboratory has been involved in understanding the signaling pathways regulated by p63 to better understand the role of p63 in development as well as cancer. We have studied the effects of naturally occurring mutant forms of p63 on the biological activity of p53 and p63 and shown that the mutant p63 differentially regulates known p53 and p63 target genes and could explain the difference in the biology of two members of the p53 family, p53 and p63. We have shown that p63 regulates sonic hedgehog, known to be important in both development and cancer. Recently we demonstrated that ΔNp63α, the most abundant and physiologically relevant p63 isoform, negatively regulates PTEN, a tumor suppressor gene often deregulated in a variety of cancer including the model system we focus on in my laboratory, skin cancer. Our studies on examining the role of p63 in cancer progression demonstrated that vitamin D receptor (VDR) is regulated by p63 and p73, another member of the p53 family and its biological significance. Currently studies in my laboratory are focused on examining the mechanism behind feedback regulation of p63 by VDR and VD3.These studies will address the discrepancy whether VD3 inhibits or promotes cell survival and provide further insight into its use as a chemotherapeutic adjuvant for anti-cancer therapy and fill the gap in the understanding of VD3 mediated regulation of ΔNp63α levels and its role in the development and progression of non melanoma skin cancer.
Recently my laboratory has been involved in examining the differential expression of known microRNAs and unknown small RNAs in tissue and plasma sample of patients with Barrett’s esophagus (BE), Esophageal adenocarcinoma (EAC) in order to identify circulating microRNA biomarkers for early detection of EAC using next generation sequencing. My laboratory has recently received funding to obtain next generation sequencer along with the top of the line Real time PCR machine with high throughput capabilities to facilitate these studies.
