    The Circadian Cryptochrome, CRY1, Is a Pro-Tumorigenic Factor that Rhythmically Modulates DNA Repair

    The authors demonstrated that CRY1 expression was androgen-responsive and associated with poor outcome in prostate cancer. Functional studies and first-in-field mapping of the CRY1 cistrome and transcriptome revealed that CRY1 regulated DNA repair and the G2/M transition.

    Chalcone Suppresses Tumor Growth through NOX4-IRE1α Sulfonation-Ridd-miR-23b Axis

    The IRE1α sulfonation-induced “regulated IRE1α-dependent decay” (RIDD) degraded miR-23b, enhancing the expression of NADPH oxidase 4 (NOX4). The expression of NOX4 was also upregulated in breast, and prostate cancer tissue.

    Droplet-Based mRNA Sequencing of Fixed and Permeabilized Cells by CLInt-Seq Allows for Antigen-Specific TCR Cloning

    Scientists applied CLInt-Seq to identify T cell receptors (TCRs) reactive with peptide epitopes of prostatic acid phosphatase, which had been pursued by multiple groups as an immunotherapeutic target in prostate cancer.

    Melatonin Interrupts Osteoclast Functioning and Suppresses Tumor-Secreted RANKL Expression: Implications for Bone Metastases

    Investigators observed that melatonin inhibited RANKL production in lung and prostate cancer cells by downregulating the p38 MAPK pathway, which in turn prevented cancer-associated osteoclast differentiation.

    Abstract

    Suppressing BCL-XL Increased the High Dose Androgens Therapeutic Effect to Better Induce the Enzalutamide-Resistant Prostate Cancer Autophagic Cell Death

    Scientists found that the antiandrogen Enzalutamide-resistant prostate cancer cells can be suppressed by hyper-physiological doses of the androgen DHT.

    Reciprocal Interactions between Tumour Cell Populations Enhance Growth and Reduce Radiation Sensitivity in Prostate Cancer

    Researchers evaluated whether interactions between heterogenous populations could impact growth and response to radiotherapy in prostate cancer.

    Regulation of Carcinogenesis and Mediation through Wnt/β-Catenin Signaling by 3,3′-Diindolylmethane in an Enzalutamide-Resistant Prostate Cancer Cell Line

    To investigate whether combined treatment with Enzalutamide (ENZ) and 3,3′-diindolylmethane (DIM) could overcome ENZ resistance by regulating Wnt signaling to inhibit androgen receptor signaling and EMT in ENZ-resistant prostate cancer cells, 22Rv1 cells were cultured in normal medium and treated with ENZ, DIM, and DIM with ENZ.

    Androgen Receptor and Its Splice Variant, AR-V7, Differentially Induce mRNA Splicing in Prostate Cancer Cells

    The capacity of two androgen receptor (AR) isoforms to regulate splicing was examined. RNA-seq data from models that endogenously expressed AR and expressed AR-V7 in response to doxycycline were used.

    Clinical Implications of Genomic Alterations in Metastatic Prostate Cancer

    The authors discuss the potential for genomic subtyping to improve prognostication and to help guide treatment selection. They summarize data on associations between androgen receptor (AR) pathway alterations and patient response to AR signaling inhibitors and other standards of care.
