In Bcap-37 cells, Spautin-1 dramatically enhanced cell death in glucose-free media and induces apoptotic morphology. In Bax-Bak DKO cells, spautin-1 inhibits etoposide induced autophagic cell death. Spautin-1 promots the degradation of Vps34 complexes by regulating the deubiquitination activity of USP10 and USP13, and reduces the levels of PtdIns3P. [1] In PDGF-treated cells, spautin-1 stabilizes α-smooth muscle cell actin and calponin, prevents actin filament disorganization, diminishes production of extracellular matrix, and abrogates VSMC hyperproliferation and migration. [2] In CML cells, spautin-1 markedly inhibits IM-induced autophagy by downregulating Beclin-1, and enhances IM-induced apoptosis by inactivating PI3K/AKT and activating downstream GSK3β. [3] Spautin-1 also specifically reduces infectious dengue virus titers in BHK-21 cells. [4]
