In light of emerging evidence that antioxidants can have cancer-promoting effects, Swamynathan et al. tested potential pro-oxidant interventions (see the Perspective by Pannia and Dowling). In particular, the authors focused on menadione sodium bisulfite, a water-soluble precursor of vitamin K. As the authors anticipated, this menadione derivative suppressed prostate cancer growth. The researchers then examined… Continue reading Dietary pro-oxidant therapy by a vitamin #K precursor targets PI 3-kinase VPS34 function

Association of Terazosin, Doxazosin, or Alfuzosin Use and Risk of #Dementia With #Lewy Bodies in Men
Background and ObjectivesTerazosin, doxazosin, and alfuzosin (Tz/Dz/Az) are α-1 adrenergic receptor antagonists that also bind to and activate a key adenosine triphosphate (ATP)–producing enzyme in glycolysis. It is hypothesized that the increase in energy availability in the brain may slow or prevent neurodegeneration, potentially by reducing the accumulation of alpha-synuclein. Recent work has suggested a… Continue reading Association of Terazosin, Doxazosin, or Alfuzosin Use and Risk of #Dementia With #Lewy Bodies in Men

#Prostate Safety Events During #Testosterone Replacement Therapy in Men With HypogonadismA Randomized Clinical Trial
Importance The effect of testosterone replacement therapy (TRT) on the risk of prostate cancer and other adverse prostate events is unknown.Objective To compare the effect of TRT vs placebo on the incidences of high-grade prostate cancers (Gleason score ≥4 + 3), any prostate cancer, acute urinary retention, invasive prostate procedures, and pharmacologic treatment for lower urinary tract… Continue reading #Prostate Safety Events During #Testosterone Replacement Therapy in Men With HypogonadismA Randomized Clinical Trial
African American Prostate Cancer Displays Quantitatively Distinct Vitamin D Receptor Cistrome-transcriptome Relationships Regulated by BAZ1A
African American (AA) prostate cancer associates with vitamin D3 deficiency, but vitamin D receptor (VDR) genomic actions have not been investigated in this context. We undertook VDR proteogenomic analyses in European American (EA) and AA prostate cell lines and four clinical cohorts. Rapid immunoprecipitation mass spectrometry of endogenous protein (RIME) analyses revealed that nonmalignant AA… Continue reading African American Prostate Cancer Displays Quantitatively Distinct Vitamin D Receptor Cistrome-transcriptome Relationships Regulated by BAZ1A
Fifteen-Year Outcomes after Monitoring, Surgery, or Radiotherapy for Prostate Cancer
BACKGROUNDBetween 1999 and 2009 in the United Kingdom, 82,429 men between 50 and 69 years of age received a prostate-specific antigen (PSA) test. Localized prostate cancer was diagnosed in 2664 men. Of these men, 1643 were enrolled in a trial to evaluate the effectiveness of treatments, with 545 randomly assigned to receive active monitoring, 553… Continue reading Fifteen-Year Outcomes after Monitoring, Surgery, or Radiotherapy for Prostate Cancer
Microbiomes of Urine and the Prostate Are Linked to Human Prostate Cancer Risk Groups
Bacteria play a suspected role in the development of several cancer types, and associations between the presence of particular bacteria and prostate cancer have been reported. ObjectiveTo provide improved characterisation of the prostate and urine microbiome and to investigate the prognostic potential of the bacteria present. Design, setting, and participantsMicrobiome profiles were interrogated in sample… Continue reading Microbiomes of Urine and the Prostate Are Linked to Human Prostate Cancer Risk Groups
Impact of #diverticular disease on #prostate cancer risk among #hypertensive men
Prostate cancer (PCa) is a heterogenous disease with multiple etiological factors playing a role in its development. Recently, chronic and systemic inflammatory conditions such as inflammatory bowel disease were identified as key risk factors influencing its development. The study aimed to evaluate the relationship between diverticular disease (DD) (local and acute inflammation) and PCa. MethodsHypertensive… Continue reading Impact of #diverticular disease on #prostate cancer risk among #hypertensive men
The association between occupational #asbestos exposure with the risk of incidence and mortality from #prostate #cancer: a systematic review and meta-analysis
There is conflicting evidence on the association between asbestos exposure and prostate cancer (PCa). Two recent meta-analyses have claimed that exposure is associated with increased PCa incidence and mortality, but they suffer from some methodological flaws. Given the potential importance of this research question, we aimed to perform a methodologically sound systematic review and meta-analysis… Continue reading The association between occupational #asbestos exposure with the risk of incidence and mortality from #prostate #cancer: a systematic review and meta-analysis
