    Intratumoral Androgen Biosynthesis Associated with 3β-Hydroxysteroid Dehydrogenase 1 Promotes Resistance to Radiotherapy in Prostate Cancer

    Germline inheritance of the adrenally permissive allele confers worse outcomes in men with advanced prostate cancer. Scientists investigated whether HSD3B1 (1245C) drove resistance to combined androgen deprivation and radiotherapy.

    Antitumor Activity of AZD0754, a dnTGFβRII-Armored, STEAP2-Targeted CAR-T Cell Therapy, in Prostate Cancer

    Studies revealed that six-transmembrane epithelial antigen of prostate-2 (STEAP2) was a prevalent prostate cancer antigen that displayed high, homogeneous cell surface expression across all stages of disease with limited distal normal tissue expression.

    Targeting DNA Methylation and B7-H3 in RB1-Deficient and Neuroendocrine Prostate Cancer

    Researchers identified that deletion of DNA methyltransferases genes decreased expression of neuroendocrine lineage markers and substantially reduced neuroendocrine prostate cancer tumor development and metastasis in vivo.

    A Novel Primary Cilium-Mediated Mechanism through which Osteocytes Regulate Metastatic Behavior of Both Breast and Prostate Cancer Cells

    Using a series of co-culture, conditioned media, human cancer spheroid, and organ-on-a-chip experiments, the authors revealed that osteocytes suppressed cancer cell proliferation and increased migration via tumor necrosis factor alpha secretion.

    Targeting CBX3 with a Dual BET/PLK1 Inhibitor Enhances the Antitumor Efficacy of CDK4/6 Inhibitors in Prostate Cancer

    Investigators demonstrated that CBX3 was abnormally upregulated in CDK4/6 inhibitors-resistant cells, and that CBX3 was almost positively correlated with the cell cycle in multiple malignancies and was downregulated by BET inhibitors.

    Targeting the αVβ3/NgR2 Pathway in Neuroendocrine Prostate Cancer

    Using in vitro functional assays, researchers demonstrated that NgR2 was crucial in promoting cell adhesion to αVβ3 ligands. They described for the first time co-fractionation of αVβ3 integrin and NgR2 in small extracellular vesicles derived from metastatic prostate cancer patients’ plasma.

    Abstract

    The Key Cellular Senescence Related Molecule RRM2 Regulates Prostate Cancer Progression and Resistance to Docetaxel Treatment

    The authors explored the role of Ribonucleotide reductase subunit M2 (RRM2), a gene associated with senescence, in the sensitivity of prostate cancer to docetaxel.

    A Complex with poly(A) Binding Protein and EWS Facilitates the Transcriptional Function of Oncogenic ETS Transcription Factors in Prostate Cells

    Expression of the ETS transcription factor ERG in prostate cells promoted PABPC1 localization to the nucleus and recruited PABPC1 to ERG/EWS binding sites in the genome.

    Identification of DNA Damage Response-Related Genes As Biomarkers for Castration-Resistant Prostate Cancer

    Functional analysis demonstrated that silencing of RFC2 expression inhibited cell proliferation and induced the expression of DNA damage and apoptosis markers in castration-resistant prostate cancer model cells.

    Marcus Ruscetti Receives American Cancer Society Award for Prostate Cancer Research

    “What we will do with this American Cancer Society grant is try to understand why sometimes senescence is good and stops tumors from growing and other times it’s bad and leads to immune suppression,” Dr. Ruscetti said.
