Scientists engineer therapeutic system with two arms to get better hold on cancer target

Posted on Leave a commentPosted in Biomedical Science, Cancer, DNA, Genetics, Medical News, Pharmaceuticals, Pioneering Technology

Scientists have engineered a sort of biological barbell that can get inside cancer cells and do damage to two proteins that work independently and together to enable cancer’s survival and spread. Their therapeutic strategy includes a molecule on either end called an aptamer that targets, in this case, prostate cancer. Sandwiched in between are two […]
