    Immunoproteasome Inhibition Prevents Progression of Castration-Resistant Prostate Cancer

    The immunoproteasome subunit LMP7 was silenced by using gene knockout or inhibited by the epoxyketone inhibitor ONX 0914 in a mouse castration-resistant prostate cancer (CRPC) tumor graft model and in interferon-γ-pretreated human CRPC cell lines in vitro.

    Viscosalactone B, a Natural LSD1 Inhibitor, Inhibits Proliferation In Vitro and In Vivo against Prostate Cancer Cells

    Viscosalactone B was first identified as a novel lysine-specific demethylase 1 (LSD1) inhibitor. Viscosalactone B isolated from Withania Somnifera displayed antiproliferative activity against PC3, DU145, C42B, PC3/MDVR, DU145/MDVR, and C42B/MDVR cells.

    Abstract

    GLIDR Promotes the Aggressiveness Progression of Prostate Cancer Cells by Sponging miR-128-3p

    Scientists investigated the role and molecular mechanism of glioblastoma downregulated RNA (GLIDR) in prostate cancer (PCa) cells. The results showed that GLIDR expression levels were higher in PCa samples and cells than in the control.
