multiple myeloma cells are often able to survive by increasing the production of a protein known as Mcl-1. Mcl-1 regulates a number of processes that promote cell survival and has been implicated in resistance to anti-myeloma drugs that were initially effective. However, a team of researchers ... recently published the findings of a study ... demonstrating that a novel drug combination both reduces Mcl-1 expression and disrupts its interactions with other proteins to effectively kill multiple myeloma cells. The therapy combines a type of drug known as a Chk1 inhibitor with another called a MEK inhibitor.
