Biophysicist attempts to block protein to prevent breast, prostate cancer

Washington, Apr 20 (ANI): An Ohio State biophysicist has targeted a protein molecule Interleukin-6 (IL-6) to halt breast and prostate cancer.Chenglong Li, used a supercomputer to search thousands of molecular combinations for the best configuration to block a protein that can cause breast or prostate cancer.Li Is leveraging a powerful computer cluster at the Ohio Supercomputer Center (OSC) to develop a drug that will block the small protein molecule Interleukin-6 (IL-6). The body normally produces this immune-response messenger to combat infections, burns, traumatic injuries, etc. Scientists have found, however, that in people who have cancer, the body fails to turn off the response and overproduces IL-6.Based on the a series of investigations into IL-6 in the past to synthesize effective cancer drugs, Li recognized the potential of those initial insights and partnered last year with an organic chemist and a cancer biologist at OSU’s James Cancer Hospital to further investigate, using an OSC supercomputer to construct malleable, three-dimensional color simulations of the protein complex.”We proposed using computational intelligence to re-engineer a new set of compounds that not only preserve the original properties, but also would be more potent and efficient,” Li said. “Our initial feasibility study pointed to compounds with a high potential to be developed into a non-toxic, orally available drug,” he added. “While we didn’t promise to have a drug fully developed within the two years of the project, we’re making excellent progress,” said Li. “The current research offers us an exciting new therapeutic paradigm: targeting tumour microenvironment and inhibiting tumour stem cell renewal, leading to a really effective way to overcome breast tumour drug resistance, inhibiting tumour metastasis and stopping tumour recurrence,” added Li.
