Pasireotide induces proteins related to autophagy in cancer cells
摘要
Purpose
To investigate the possibility that Pasireotide (PAS), which is a synthetic somatostatin analog (SSA), induces proteins related to autophagy in cancer cells.
MethodsMDA-MB-468 and HeLa human cancer cells were exposed to PAS or vehicle for 8, 24 and 32 h, to assess possible effects in autophagy-related proteins. Western blot analysis was utilized to assess changes in protein expression levels due to PAS exposure.
ResultsPAS treatment induces the expression of the autophagy-related protein (ATG)-3, ATG-7, and Beclin-1 in MDA-MB-468 and HeLa cells.
ConclusionsOur findings suggest that the beneficial effects of PAS in cancers may involve autophagy. Further studies will attempt to elucidate the underlying mechanisms mediating those effects.
