Biomedical Sciences Graduate Student Brandon Shiflett has been selected for a special honor by the American Society for Investigative Pathology (ASIP). Brandon is only one of eighteen students who have been chosen to present their research projects at a special session of the ASIP Annual Meeting at Experimental Biology 2011 in Washington, DC. The session is entitled “Highlights: Graduate Student Research in Pathology.” According to the ASIP, it is considered an honor to be invited to this special session. More about the ASIP, its annual meeting, and this special session can be found on the ASIP website.
Brandon’s abstract is entitled “MG624, an α-7nicotinic receptor antagonist suppresses the growth of human SCLC.” SCLC, or Small Cell Lung Cancer, is a rapidly-progressing disease that metastasizes early and has very low survival rates. Interestingly, nearly 90% of all reported SCLC cases have been correlated to smoking, which suggests that nicotine and other tobacco components may contribute to the disease’s pathophysiology. The data Brandon will present shows that long-term nicotine exposure stimulates the growth of human SCLCs. Nicotine stimulates nicotinic acetylcholine receptors (nAChRs), causing these cells to proliferate. By isolating and disabling a specific subunit of a nicotinic acetylcholine receptor, α7-nAChR, Brandon and others on his project were able to suppress nicotine’s stimulatory effects. This indicates that the α7-nAChR subtype is important in the proliferation of human SCLCs, and that antagonizing it could be a possible treatment for the condition. One such antagonist, called MG624, was shown in Brandon’s study to not only induce apoptosis, or cell death, in human SCLC cells, but also suppress the nicotine-induced growth of these cells. The data from his study suggests that MG624 may have potential for treating human SCLCs.
Brandon Shiflett works in the laboratory of Dr. Piyali Dasgupta at the Marshall University Joan C. Edwards School of Medicine. He is currently completing his second year as a Medical Sciences student in the M.S. in Biomedical Sciences Program at Marshall. He will join the medical school in the fall as a first-year student.
Congratulations to Brandon Shiflett, Dr. Dasgupta, and all others who participated in this project!
