    A Novel Role for DNA-PK in Metabolism by Regulating Glycolysis in Castration Resistant Prostate Cancer

    DNA-dependent kinase catalytic subunit (DNA-PK) regulation of metabolism was interrogated using pharmacological and genetic perturbation using in vitro cell models, in vivo xenografts, and ex vivo in patient-derived explants.

    THEM6-Mediated Reprogramming of Lipid Metabolism Supports Treatment Resistance in Prostate Cancer

    Scientists identified thioesterase superfamily member 6 (THEM6) as a marker of androgen-deprivation therapy resistance in prostate cancer. THEM6 deletion reduced in vivo tumor growth and restored castration sensitivity in orthograft models of CRPC.

    Targeting a Splicing-Mediated Drug Resistance Mechanism in Prostate Cancer by Inhibiting Transcriptional Regulation by PKCβ1

    PKCβ inhibition reduced total androgen receptor (AR) gene expression, thus reducing AR-V7 protein levels and sensitizing prostate cancer cells to current anti-androgen therapies.

    E2F Transcription Factor 2-Activated DLEU2 Contributes to Prostate Tumorigenesis by Upregulating Serum and Glucocorticoid-Induced Protein Kinase 1

    Researchers suggested that E2F transcription factor 2-activated DLEU2 may function as a competing endogenous RNA to facilitate prostate cancer progression by targeting the miR-582-5p/SGK1 axis.

    Olaparib Induced Senescence is Bypassed through G2/M Checkpoint Override in Olaparib Resistant Prostate Cancer

    Investigators characterized responses to olaparib in sensitive LNCaP and C4-2B cells and developed two olaparib resistant derivative cell line models from each. They found that olaparib induced massive DNA damage, leading to activation of the G2/M checkpoint, activation of p53, and cell cycle arrest.

    Abstract

    HER2 Mediates PSMA/mGluR1-Driven Resistance to the DS-7423 Dual PI3K/mTOR Inhibitor in PTEN Wild-Type Prostate Cancer Models

    Scientists investigated the response of PTEN wild-type prostate cancer cell lines to the dual PI3K/mTOR inhibitor DS-7423 alone or in combination with HER2 inhibitors or mGluR1 inhibitors.

    Antizyme Inhibitor 1 Regulates Matrikine Expression and Enhances the Metastatic Potential of Aggressive Primary Prostate Cancer

    Integrated copy number aberration and gene expression analysis of primary high-risk prostate cancer identified the AZIN1 gene as a novel driver of metastatic progression, by altering collagen subunit expression.

    Gene Therapy of Prostate Cancer Using Liposomes Containing Perforin Expression Vector Driven by the Promoter of Prostate-Specific Antigen Gene

    The authors investigated the therapeutic potential of liposomes containing perforin expression vector driven by the promotor of prostate-specific antigen.

    NCAPD3 Promotes Prostate Cancer Progression by Up-Regulating EZH2 and MALAT1 through STAT3 and E2F1

    In vitro and in vivo functional characterization revealed that overexpression of NCAPD3 enhanced the growth of prostate cancer (PCa) cells, while knockdown of NCAPD3 impaired the growth of PCa cells.

    Abstract

    ATF6α Promotes Prostate Cancer Progression by Enhancing PLA2G4A-Mediated Arachidonic Acid Metabolism and Protecting Tumor Cells against Ferroptosis

    Researchers found that the increase of transcription factor 6 α (ATF6α) expression in response to androgen deprivation generated prostate cancer cells with a CRPC-like phenotype.
