Professor Chun Peng leads research team uncovering how ovarian cancer resists chemotherapy

York University researchers have zeroed in on a genetic process that may allow ovarian cancer to resist chemotherapy. Researchers in the University’s Faculty of Science & Engineering studied a tiny strand of our genetic makeup known as a microRNA, involved in the regulation of gene expression. Cancer occurs when gene regulation goes haywire.

“Ovarian cancer is a very deadly disease because it’s hard to detect,” says biology Professor Chun Peng, who co-authored the study. By the time it’s diagnosed, usually it is in its late stages. And by that point there’s really no way to treat the disease. Even when the disease is discovered in its early stages, chemotherapy doesn’t always work,” she says.
