Fatty acid binding proteins in multiple myeloma

Fatty acid binding proteins (FABPs) transport fatty acids (FA) into cells as an energy source, and their inhibition suppressed tumor proliferation in solid tumors. Multiple myeloma (MM) is a hematologic malignancy, known for disrupted protein metabolism including high proteasome activity, where proteasome inhibitors made a dramatic improvement in its treatment. Recent discovery found FABPs as a novel metabolic pathway in MM, which will have an impact on understanding the biology and on therapeutic application in MM.
