    RNA Splicing Factors SRRM3 and SRRM4 Distinguish Molecular Phenotypes of Castration-Resistant Neuroendocrine Prostate Cancer

    Scientists interrogated the regulation of RE1-silencing transcription factor, a transcriptional repressor of neuronal genes, and elucidated molecular programs driving amphicrine prostate cancer and neuroendocrine prostate cancer biology.

    CRISPR Screening Identifies CDK12 as a Conservative Vulnerability of Prostate Cancer

    The authors performed a kinome-scale CRISPR/Cas9 screen and identified cyclin-dependent kinase 12 (CDK12) as being conservatively required for prostate cancer cell survival.

    lncRNA SNHG11 Facilitates Prostate Cancer Progression through the Upregulation of IGF-1R Expression and by Sponging miR-184

    Researchers investigated the functional role and molecular mechanisms of SNHG11 in prostate cancer (PCa) progression. It was revealed that the SNHG11 expression levels were significantly upregulated in PCa tissues, in comparison with those in adjacent normal tissues.

    LOC100996425 Acts as a Promoter in Prostate Cancer by Mediating Hepatocyte Nuclear Factor 4A and the AMPK/mTOR Pathway

    Investigators determined effects of LOC100996425 on human prostate cancer by targeting hepatocyte nuclear factor 4A via the AMPK/mTOR pathway.

    Biodistribution and Internal Radiation Dosimetry of a Companion Diagnostic Radiopharmaceutical, [68Ga]PSMA-11, in Subcutaneous Prostate Cancer Xenograft Model Mice

    Researchers characterized the biodistribution and pharmacokinetics of PSMA-11 in prostate-specific membrane antigen (PSMA)-positive and negative tumor-bearing mice and subsequently estimated its internal radiation dosimetry via voxel-level dosimetry using a dedicated Monte Carlo simulation to evaluate the absorbed dose in the tumor directly.

    Diagnostic Potential of Serum Extracellular Vesicles Expressing Prostate-Specific Membrane Antigen in Urologic Malignancies

    Investigators developed a sandwich ELISA to detect prostate-specific membrane antigen on small extracellular vesicles (EVs) using T-cell immunoglobulin domain and mucin domain-containing protein 4 as a capture molecule for EVs and to evaluate its diagnostic potential in urologic malignancies.

    Human Prostate Epithelial Cells and Prostate-Derived Stem Cells Malignantly Transformed In Vitro with Sodium Arsenite Show Impaired Toll Like Receptor -3 (TLR3)-Associated Anti-Tumor Pathway

    Since inorganic arsenic targets prostatic stem cells, researchers hypothesized that arsenic-transformed stem cells show an impaired TLR3-associated anti-tumor pathway and, therefore, are unresponsive to polyinosinic:polycytidylic acid activation.

    DNA-PKc Inhibition Overcomes Taxane Resistance by Promoting Taxane-Induced DNA Damage in Prostate Cancer Cells

    Scientists proposed that alterations in DNA damage response pathway contributed to taxane resistance, and identification of these alterations may provide a potential therapeutic target to resensitize docetaxel-refractory mCRPC to taxane-based therapy.

    PHLDA3 Exerts an Antitumor Function in Prostate Cancer by Down-Regulating Wnt/β-Catenin Pathway via Inhibition of Akt

    The relevance of pleckstrin homology-like domain family A, member 3 (PHLDA3) in prostate cancer has not been explored. Scientists illustrated the possible roles and mechanisms of PHLDA3 in prostate cancer.

    Androgen Receptor Antagonists Produced by Streptomyces Overcome Resistance to Enzalutamide

    From the natural product screening, the novel compound arabilin was isolated from Streptomyces sp. MK756-CF1. Unlike STK765173, arabilin could overcome resistance to enzalutamide.

    Cardiff Researcher Awarded £230K to Transform Prostate Cancer Treatment

    Researchers from Cardiff University have received a grant worth over £230,000 from leading men’s health charity Prostate Cancer UK. The funding will help them develop a deeper understanding of how prostate cancer affects the immune system, so it’s clearer which men could benefit from powerful new immunotherapy treatments.
