Anthrax Toxin May Be Effective Weapon in Fighting Bladder Cancer

Anthrax may soon help more people win the fight against bladder cancer, which the Centers for Disease Control and Prevention (CDC) says strikes approximately 72,000 Americans each year and kills about 16,000, and is one of the most expensive cancers to treat. The current treatments for bladder cancer are invasive for patients - who often must sit for hours at a time with a bladder full of an agent designed to kill cancer cells and tumors. Bladder cancer also is one of the most reoccurring for people diagnosed with the disease. Now, researchers at Purdue University have come up with a way to combine the anthrax toxin (image) with a growth factor to kill bladder cancer cells and tumors. The research was published online on October 4, 2019 in the International Journal of Cancer. "We have effectively come up with a promising method to kill the cancer cells without harming the normal cells in the bladder," said R. Claudio Aguilar, PhD, an Associate Professor and the Assistant Head of Biological Sciences in Purdue's College of Science. "It is basically like creating a special solution that targets cancer cells, while leaving healthy cells alone." Dr. Aguilar said the bladder has its own protective layer, which saves the good cells from the anthrax mixture but offers no protection for the cancer cells and tumors. He said the Purdue system works within minutes - instead of the usual hours for bladder cancer treatment - to target the cancer cells in the bladder. "We have seen outstanding results with our treatment," said Dr. Aguilar, who works as part of a team focused on cell identity and signaling at the Purdue University Center for Cancer Research. "It is fast and effective, both of which are critical for people dealing with this devastating disease."
