Personal profile

researchinterests

My research focuses on two major areas: 1) Cancer therapy: T-oligo: My cancer therapy research focuses on developing novel targeted therapies using T-oligo. We have found T-oligo (nucleotides homologous to the telomere overhang) to be therapeutically effective in lung cancer and melanoma cells and pre-established tumor xenografts by inducing apoptosis and senescence. We are currently attempting to deliver T-oligo as a nanoparticle complexed with a cationic peptide to melanoma tumors in mice. Lung Cancer: My project on lung cancer aims to unravel the mechanism of EGFR/c-Met tyrosine kinase inhibitor (TKI) resistance in Non-Small Cell lung cancer by studying the signaling pathways in resistant and parental NSCLC cell lines with and without EGFR TK mutations. Recent studies in our lab demonstrate activation of alternative signaling pathways in resistant cell lines which can be targeted along with EGFR and c-Met pathways to overcome or delay the TKI resistance. Currently, we are also investigating the role of epithelial mesenchymal transition in the development of resistance in NSCLC. Our translational research focuses on identifying the role of biomarkers EGFR/c-Met and key proteins from the mTOR and Wnt signaling pathways, in prognosis of NSCLC patients using immunohistochemistry. Melanoma: My cancer research also focuses on melanoma, where we have successfully evaluated the role of c-Met as a molecular target in melanoma. We are currently investigating the mechanism and TKI combination therapies to overcome c-Met and BRAF resistance in wild type and melanoma cell lines with a BRAF mutation. 2) Role of FTO in obesity: This project aims at identifying the role of FTO in promoting obesity in humans. We have downregulated FTO with siRNA and using a microarray studied affected genes. We have constructed a pathway from the microarray data and are currently identifying key targets. We are investigating the mechanism of how FTO induces obesity. Our recent studies indicate that FTO modulates intracellular energy levels and downstream signaling mechanisms which control energy intake and metabolism.
