Arup Bhattacharya, PhD
Biography
Dr. Arup Bhattacharya joined the PhD program in Cellular and Molecular Biophysics in the Roswell Park Graduate Division, SUNY at Buffalo in 1999. After completing his PhD in 2005, he did his postdoctoral training in Translational Pharmacology and Physiology under Dr Youcef M. Rustum in the Department of Cancer Biology. His postdoctoral training was supported partly by a postdoctoral grant from American Institute for Cancer Research. Since 2009 he is an Affiliate member in the Department of Cancer Prevention and Control.
Background
The role of MSC as a therapeutic agent in augmenting chemotherapeutic efficacy in combination chemotherapy is being investigated in terms of a common underlying factors. The relevance of histomorphology and tumor cell differentiation on the therapeutic efficacy is being pursued for determining clinic relevance. This study is currently being supported by an NCI grant.
Bladder cancer is one of the most expensive cancers to treat due to repeated recurrence and in the clinic it leads to higher mortality when it invades the bladder wall. Using in vivo preclinical bladder cancer model, the antitumor activity of various ITCs and ITC containing natural substances is being pursued.
Homeopathy has remained in the fringe due to paucity of studies in basic science. There has recently been validated report of its possible efficacy in some cancers. Research is being pursued to check the feasibility in vivo of using some homeopathic remedies for its possible anticancer efficacy.
Three components of Dr. Arup’s research are:
- Anticancer effects of dietary supplement selenium especially focusing on the organoselenium compound methylselenocysteine for its unique properties including a low toxicity profile in vivo. The effect on HIF-1α, VEGF, iNOS, Cox-2 is being studied in order to understand the antiangiogenic efficacy of MSC in vivo.
- The anticancer role of isothiocyanate (ITCs) and ITC containing natural products in retarding bladder cancer growth, progression and invasion.
- Possible anticancer efficacy of some homeopathic remedies in vivo.
