    SMAD3 Promotes Expression and Activity of the Androgen Receptor in Prostate Cancer

    Using RNA-seq, scientists revealed that SMAD3 knockdown decreased levels of androgen receptor (AR) and AR target genes, whereas SMAD4 or SMAD2 knockdown had little or no effect.

    PI5P4Kα Supports Prostate Cancer Metabolism and Exposes a Survival Vulnerability during Androgen Receptor Inhibition

    Researchers explored the phosphatidylinositol-5-phosphate 4-kinases (PI5P4K) and demonstrated that the PI5P4Kα isoform influenced androgen receptor signaling, which supported prostate cancer cell survival.

    Cannabidiol Alters Mitochondrial Bioenergetics via VDAC1 and Triggers Cell Death in Hormone-Refractory Prostate Cancer

    Investigators demonstrated that two multi-target natural products, cannabidiol and cannabigerol, suppressed hormone refractory prostate cancer development in the transgenic adenocarcinoma of the mouse prostate model by reprogramming metabolic and oncogenic signaling.
