Researchers target rapid destruction of protein responsible for cancer cell resistance to therapy

“These findings may lead to a new target for chemoresistant cancer cells,” said Ruth W. Craig, PhD, professor of Pharmacology & Toxicology, Geisel School of Medicine at Dartmouth, Hanover, NH, who is primary author of the peer reviewed article. “These cells are resistant to multiple types of standard chemotherapeutic agents because of over-expression of Myeloid Cell Leukemia-1 (Mcl-1), however, Mcl-1 expression plummets when we inhibit one particular enzyme and then cancer cells subsequently die.” The Mcl-1 protein is frequently over-expressed in cancer; it is present not only in leukemia and lymphoma but also in a host of solid tumors. …
