Combatting drug resistance for melanoma patients

Scientists have made significant strides identifying important molecules that contribute to melanoma growth and metastases, such as the proteins BRAF and MEK. Therapeutic agents that target these molecules have shown promise in the clinic, and many patients have significant reductions in tumor growth and tumor burden. “While targeted therapy drugs, such as BRAF and MEK inhibitors, have been associated with impressive responses in melanoma patients, most patients will eventually fail therapy,” said Keiran Smalley, Ph.D., associate member of the Cancer Biology and Evolution Program at Moffitt. Tumors can develop different resistance mechanisms and adapt to targeted agents in order to survive and continue to grow. …
