    Stromal Cell-Derived Small Extracellular Vesicles Enhance Radioresistance of Prostate Cancer Cells via Interleukin-8-Induced Autophagy

    Investigators showed that stromal cell-derived small extracellular vesicles (sEVs) facilitated the radioresistance of prostate cancer (PCa) cells by transporting interleukin-8 (IL-8). Prostatic stromal cells secreted more IL-8 than AR-positive PCa cells, which could be accumulated in sEVs.

    The RNA-Binding Proteins hnRNP H and F Regulate Splicing of a MYC-Dependent HRAS Exon in Prostate Cancer Cells

    The authors performed a signaling pathway-guided splicing analysis to identify MYC-dependent splicing events. These included an HRAS cassette exon repressed by MYC across multiple tumor types.

    An Unbiased Seed-Based RNAi Selection Screen Identifies Small RNAs That Inhibit Androgen Signaling and Prostate Cancer Cell Growth

    Scientists explored a therapeutic strategy for prostate cancer based on the ability of sh/siRNAs to function essentially as miRNAs and, via seed sequence complementarity, induce RNA interference of numerous targets simultaneously.

    Cyto-IL-15 Synergizes with the STING Agonist ADU-S100 To Eliminate Prostate Tumors and Confer Durable Immunity in Mouse Models

    To determine whether the combination of cytotopically modified interleukin-15 (cyto-IL-15) with the stimulator of interferon genes (STING) agonist, ADU-S100 could lead to both local and systemic anti-tumor effects, intratumoral administration of these agents was used in murine models of prostate cancer.

    Androgen-Regulated Stromal Complement Component 7 (C7) Suppresses Prostate Cancer Growth

    Researchers showed that C7 was specifically expressed by the stromal cells in both mouse and human prostates. The expression level of C7 inversely correlated with clinical outcomes in prostate cancer.

    PARP1 Negatively Regulates Transcription of BLM through Its Interaction with HSP90AB1 in Prostate Cancer

    The expression of Bloom’s syndrome protein (BLM) in human specimens was analyzed using immnohistochemistry. A 5′-biotin-labeled DNA probe containing the promoter region of BLM was synthesized to pull down BLM promoter-binding proteins.

    Osteoblast-Derived Extracellular Vesicles Exert Osteoblastic and Tumor-Suppressive Functions via SERPINA3 and LCN2 in Prostate Cancer

    In a co-culture of osteoblasts (OBs) and osteoblastic prostate cancer (BPCa) cells, SERPINA3 and LCN2 were remarkably upregulated in BPCa via OB-derived extracellular vesicles, while they were not in the co-culture of OBs and osteolytic prostate cancer cells.

    Human Prostate Organoid Generation and the Identification of Prostate Development Drivers Using Inductive Rodent Tissues

    Scientists showed that hiPSCs can be differentiated into prostate organoids using neonatal rat seminal vesicle mesenchyme in vitro. The organoids can be used to study prostate development or modified to study prostate cancer.
