    Inhibition of CDK9 Activity Compromises Global Splicing in Prostate Cancer Cells

    The authors showed that CDK9 inhibition resulted in the loss of androgen receptor (AR) and AR-v7 expression due to the defects in splicing, which sensitized castration-resistant prostate cancer cells to androgen deprivation.

    Abstract

    Comparison of Low-Molecular-Weight Ligand and Whole Antibody in Prostate-Specific Membrane Antigen Targeted Near-Infrared Photoimmunotherapy

    Scientists investigated differences in cytotoxicity and mechanisms between LMW-IR700 and Ab-IR700 targeting prostate-specific membrane antigen.

    Abstract

    Discovery of a New Candidate Drug to Overcome Cabazitaxel-Resistant Gene Signature in Castration-Resistant Prostate Cancer by In Silico Screening

    Researchers used screening tests for candidate drugs targeting cabazitaxel (CBZ)-resistant-related gene expression and identified pimozide as a potential candidate for overcoming CBZ resistance in castration-resistant prostate cancer.

    Abstract

    Regulatory Mechanism of Androgen Receptor on NCAPD3 Gene Expression in Prostate Cancer

    NCAPD3 is an androgen/AR axis-targeted gene and is involved in androgen receptor (AR)-induced prostate cancer (PCa) cell proliferation, migration, and invasion in vitro and in vivo. Androgen treatment and AR overexpression increased the expression of NCAPD3 in PCa cell lines.

    Abstract

    Live Cell Molecular Analysis of Primary Prostate Cancer Organoids Identifies Persistent Androgen Receptor Signaling

    Using orthogonal flow cytometry analysis, scientists demonstrated that primary patient-derived cancer organoid maintain distinct subsets of epithelial cells throughout culture and that these cells conserve expression of androgen receptor-related elements.

    Bergamottin a CYP3A Inhibitor Found in Grapefruit Juice Inhibits Prostate Cancer Cell Growth by Downregulating Androgen Receptor Signaling and Promoting G0/G1 Cell Cycle Block and Apoptosis

    Researchers observed that bergamottin reduced prostate cancer cell growth by decreasing both total and nuclear AR reducing downstream AR signaling.
