Researchers reveal underlying mechanism of powerful chemotherapy for prostate cancer treatment
Date:9/17/2012

the bark of a Pacific yew tree by federal researchers in 1967 and was later synthesized. It 1993 it was approved for use in ovarian cancer, and has since been used for lung, breast, head and neck and other cancers. Taxotere (docetaxel), synthesized from chemicals extracted from the European yew tree, was developed as an alternative to Taxol, and is used for the treatment of many of the same cancer types. Cabazitaxel, the newest taxane, is a semi-synthetic paclitaxel analog and is used to treat patients with prostate cancer who have failed prior docetaxel chemotherapy.

"In the 20 years since Taxol was approved, hundreds of labs worldwide are trying to understand how taxanes work to stop cell division in cancer," Dr. Giannakakou says. "However, we think they need to now take a fresh approach and look at what these drugs do during the normal life cycle of a cancer cell and target the newly revealed underlying mechanisms and modes of movement with novel therapies, in combination with taxane therapy, to provide life-saving therapy for patients who don't benefit from taxanes."

Investigators working with Dr. Giannakakou on the study are the first author Maria Thadani-Mulero, who is a graduate student enrolled at Surrey University, UK performing her thesis work in Dr. Giannakakou's laboratory, and Dr. David M. Nanus, the Mark W. Pasmantier Professor of Hematology and Oncology in Medicine and chief of the Division of Hematology and Medical Oncology at Weill Cornell.
