A critical role of autophagy in antileukemia/lymphoma effects of APO866, an inhibitor of NAD biosynthesis

Pierre Vogel, Somi Reddy Majjigapu

APO866, an inhibitor of NAD biosynthesis, exhibits potent antitumor properties in various malignancies. Recently, it has been shown that APO866 induces apoptosis and autophagy in human hematological cancer cells, but the role of autophagy in APO866-induced ...
