LABORATORY RESEARCH Telomerase Activity and Telomere Length in Human Benign Prostatic Hyperplasia Stem-Like Cells and Their Progeny Implies the Existence of Distinct Basal and Luminal Cell Lineages Scientists investigated the telomere biology of cell subpopulations from benign prostatic hyperplasia patients undergoing transurethral resection of prostate. Measurement of TERC, TERT, and telomerase activity revealed that only the epithelial stem-like and progenitor fractions expressed high levels of telomerase activity and individual enzyme components. [Eur Urol] Abstract | Press Release Optimization of TRPV6 Calcium Channel Inhibitors Using a 3D Ligand-Based Virtual Screening Method Researchers report the discovery of the first potent and selective inhibitor of TRPV6, a calcium channel overexpressed in breast and prostate cancer, and its use to test the effect of blocking TRPV6-mediated Ca2+-influx on cell growth. [Angew Chem Int Ed Engl] Abstract The Androgen Receptor Controls Expression of the Cancer-Associated sTn Antigen and Cell Adhesion through Induction of ST6GalNAc1 in Prostate Cancer Scientists used RNA-Seq coupled with bioinformatic analyses of androgen-receptor (AR) binding sites and clinical prostate cancer (PCa) expression array data to identify ST6GalNAc1 as a direct and rapidly activated target gene of the AR in PCa cells. [Oncotarget] Full Article miR-573 Inhibits Prostate Cancer Metastasis by Regulating Epithelial-Mesenchymal Transition Researchers found that microRNA-573 (miR-573) expression is significantly lower in metastatic tissues than matched primary prostate cancer (PCa). Its downregulation is correlated with high Gleason score and cancer-related mortality of PCa patients. [Oncotarget] Full Article GSTP1 Loss Results in Accumulation of Oxidative DNA Base Damage and Promotes Prostate Cancer Cell Survival following Exposure to Protracted Oxidative Stress Scientists explored the effects of restored glutathione S-transferase π (GSTP1) expression on glutathione levels, accumulation of oxidative DNA damage, and prostate cancer cell survival following oxidative stress induced by protracted, low dose rate ionizing radiation. [Prostate] Abstract CSL Regulates AKT to Mediate Androgen Independence in Prostate Cancer Progression A subpopulation of casodex resistant prostate cancer cells were identified with an overexpressed androgen receptor and aggressive phenotypes, characterized with high proliferation, invasion in vitro and enhanced tumorigenesis in vivo. [Prostate] Abstract Intrauterine Exposure to Bisphenol A Promotes Different Effects in Both Neonatal and Adult Prostate of Male and Female Gerbils (Meriones unguiculatus) Investigators describe the prostate development in both male and female neonatal gerbils in normal conditions and under exposure to bisphenol A (BPA) during intrauterine life, and also to analyze whether the effects of intrauterine exposure to BPA remain in adulthood. [Environ Toxicol] Abstract Examination of PACAP-Like Immunoreactivity in Urogenital Tumor Samples Researchers compared pituitary adenylate cyclase-activating polypeptide (PACAP)-like immunoreactivity in different healthy and pathological human samples from urogenital organs (kidney, urinary bladder, prostate, testis) with radioimmunoassay method. [J Mol Neurosci] Abstract CLINICAL RESEARCH Clinical and Translational Assessment of VEGFR1 as a Mediator of the Pre-Metastatic Niche in High-Risk Localized Prostate Cancer A randomized, Phase II clinical trial comparing axitinib for 28 days followed by radical prostatectomy and pelvic lymph node dissection (RP/PLND) to RP/LND alone was conducted, with the primary endpoint of demonstrating downregulation of VEGFR1-positve cell clustering in benign lymph nodes. [Mol Cancer Ther] Abstract Risk of Second Primary Cancer among Prostate Cancer Patients in Korea: A Population-Based Cohort Study As patients with prostate cancer have a long life expectancy, there is increasing interest in predicting the risk of development of a second primary cancer (SPC), and investigators therefore estimated the overall risk of developing SPCs among Korean prostate cancer patients.
