FIU scientists are battling prostate cancer at the cellular level.
Researchers from FIU’s Biomolecular Sciences Institute (BSI) and the Herbert Wertheim College of Medicine believe they can eradicate prostate cancer that returns in patients who were treated by castration.
Castration-resistant prostate cancer has no known cure, with 75 percent of patients dying within five years of onset. The problem lies at the very core of the human body — DNA. When damage occurs within a person’s DNA, it can cause a mutation in the DNA sequence. This is typically fixed by a process called DNA repair, a function that exists in all cells. It is typically a good thing, except when it comes to cancer, where the repair actually helps the bad cells thrive. To make matters worse, DNA repair in cancer cells occurs at a higher and more efficient rate than in normal cells. So while normal cells go through a natural life cycle in which they replicate and eventually die off, cancer cells keep multiplying.
