PCSK9 Axis-Targeting Pseurotin A as a Novel Prostate Cancer Recurrence Suppressor Lead.

ABSTRACT: Prostate cancer (PC) is the most common malignancy and the second leading cause of cancer death in men. Proprotein convertase subtilisin/kexin type 9 (PCSK9) plays an important role in the cholesterol metabolism by regulating the LDL receptor (LDLR) degradation. The PCSK9 axis is proved to be a potential novel therapeutic target in multiple cancer types. Pseurotin A (PS) is a small-molecule natural-product inhibitor of PCSK9 expression and PCSK9-LDLR protein-protein interaction (PPI). The in vitro results of this study show that PS treatments caused dose-dependent suppression of migration, colony formation, and PCSK9 expression in the PC cell lines PC-3 and 22Rv1. PS suppressed the in vivo progression of PC-3 cells orthotopically xenografted in nude mice and prevented locoreg
