    Role of Specialized Composition of SWI/SNF Complexes in Prostate Cancer Lineage Plasticity

    Using large patient datasets, patient-derived organoids and cancer cell lines, researchers identified mSWI/SNF subunits that were deregulated in neuroendocrine prostate cancer and demonstrated that SMARCA4 overexpression was associated with aggressive disease.

    Preclinical Studies Using Cisplatin/Carboplatin to Restore the Enzalutamide Sensitivity via Degrading the Androgen Receptor Splicing Variant 7 (ARv7) to Further Suppress Enzalutamide Resistant Prostate Cancer

    Scientists found that Cisplatin or Carboplatin, currently used in chemotherapy/radiation therapy to suppress tumor progression, could restore the Enzalutamide (Enz) sensitivity in multiple Enz-resistant castration-resistant prostate cancer cells via directly degrading/suppressing ARv7.

    The Roles of ZnT1 and ZnT4 in Glucose-Stimulated Zinc Secretion in Prostate Epithelial Cells

    The authors report some initial observations that provided new insights into zinc processing during glucose-stimulated zinc secretion in the immortalized human prostate epithelial cell line, PNT1A.

    Abstract

    LncRNA AFAP1-AS1 Modulates the Sensitivity of Paclitaxel-Resistant Prostate Cancer Cells to Paclitaxel via miR-195-5p/FKBP1A Axis

    The levels of AFAP1-AS1 and FKBP1A were upregulated in prostate cancer (PCa) tissues and cells, as well as PTX-resistant PCa cells, while the expression of miR-195-5p was declined.

    Abstract

    LPCAT1 Enhances Castration Resistant Prostate Cancer Progression via Increased mRNA Synthesis and PAF Production

    Investigators found that lysophosphatidylcholine acyltransferase1 (LPCAT1) overexpression enhanced the proliferation, migration, and invasion of castration resistant prostate cancer (CRPC) cells both in vitro and in vivo. Silencing of LPCAT1 reduced the proliferation and the invasive capabilities of CRPC cells.

    Abstract

    Insights into the Role of Sialylation in Cancer Progression and Metastasis

    The authors explore insights into the mechanisms by which hypersialylation plays a role in promoting metastasis, and explore the current state of sialyltransferase inhibitor development.
