INTRODUCTION: As the transgender patient population continues to increase, urologists and other providers who treat genitourinary malignancies will increasingly encounter cases of prostate cancer in transgender women. Little exists in the current literature to help summarize the challenges and opportunities which face this unique patient population. Similarly, little exists to provide guidance on how we may best diagnose, manage, and follow transgender women diagnosed with prostate cancer...

COBRA1 (co-factor of BRCA1) is one of the four subunits of the negative elongation factor originally identified as a BRCA1-interacting protein. Here, we provide first-time evidence for the oncogenic role of COBRA1 in prostate pathogenesis. COBRA1 is aberrantly expressed in prostate tumors. It positively influences androgen receptor (AR) target gene expression and promoter activity. Depletion of COBRA1 leads to decreased cell viability, proliferation, and anchorage-independent growth in prostate cancer cell lines...

Baricitinib (Olumiant® ) is an oral, targeted synthetic DMARD that inhibits JAK1 and JAK2, which are implicated in the pathogenesis of rheumatoid arthritis (RA). This novel, small molecule is approved for use as monotherapy, or in combination with methotrexate, for the treatment of adults with moderate to severe active RA who responded inadequately to or were intolerant of ≥ 1 DMARD. In pivotal multinational trials, once-daily baricitinib 4 mg, with/without methotrexate (± another csDMARD), improved the signs and symptoms of RA, disease activity and physical function in DMARD-naive patients and in patients with an inadequate response to methotrexate, csDMARDs or TNF inhibitors; baricitinib treatment also slowed structural joint damage in DMARD-naive patients and in those with an inadequate response to methotrexate and csDMARDs...

Prostate cancer alters cellular metabolism through events potentially preceding cancer morphological formation. Magnetic resonance spectroscopy (MRS)-based metabolomics of histologically-benign tissues from cancerous prostates can predict disease aggressiveness, offering clinically-translatable prognostic information. This retrospective study of 185 patients (2002-2009) included prostate tissues from prostatectomies (n = 365), benign prostatic hyperplasia (BPH) (n = 15), and biopsy cores from cancer-negative patients (n = 14)...

Biomarkers and mechanisms of poly (ADP-ribose) polymerase (PARP) inhibitor-mediated cytotoxicity in tumor cells lacking a BRCA-mutant or BRCA-like phenotype are poorly defined. We sought to explore the utility of PARP-1 inhibitor (PARPi) treatment with/without ionizing radiation in muscle-invasive bladder cancer (MIBC), which has poor therapeutic outcomes. We assessed the DNA damaging and cytotoxic effects of the PARPi olaparib in nine bladder cancer cell lines. Olaparib radiosensitized all cell lines with dose enhancement factors from 1...

Excessive adiposity (particularly visceral fat mass) increases the risks of developing metabolic syndrome. Women have lower deposit of visceral fat than men, and this pattern becomes diminished postmenopausally, but the underlying mechanism remains largely unknown. Here, we show that the gender difference in visceral fat distribution is controlled by an estradiol-autophagy axis. In C57BL/6J and wild-type control mice, a higher visceral fat mass was detected in the males than in the females, which was associated with lower expression of estrogen receptor α (ERα) and more active autophagy in males vs...

Putative gender differences in bladder cancer (BCa) have been proposed to result from sex hormone influence. Aromatase is the key enzyme catalyzing the conversion of androgens to estrogens which may result in an intratumoral microenviroment with increased estrogen production. In this study, we investigated the expression pattern of aromatase and its association with BCa progression. Tissue samples from 88 BCa patients who underwent cystectomy were obtained. Using immunohistochemistry (IHC), expression of aromatase in tumor epithelium (TE) and tumor related stroma (TS) were evaluated separately, and the association of aromatase expression status with pathologic variables and overall survival (OS) outcome was examined...

Existing drugs that have been used in clinical practice for other purposes can prove useful for reutilization, since much of the safety profile and pharmacokinetics have been completed. Therefore, the drugs can enter clinical practice for a variety of causes with less regulatory burden. Metformin may prove to be such a drug; it may have a role in other diseases, besides the management of diabetes. In this perspective, we provide our findings and understanding of metformin as an alternative way to treat urological abnormal proliferation...

Benign prostatic hyperplasia is the most common proliferative abnormality of the prostate. All men experience some prostatic growth as they age, but the rate of growth varies among individuals. Steroid 5α-reductase 2 (SRD5A2) is a critical enzyme for prostatic development and growth. Previous work indicates that one-third of adult prostatic samples do not express SRD5A2, secondary to epigenetic modifications. Here we show that the level of oestradiol is dramatically elevated, concomitant with significant upregulation of oestrogen response genes, in prostatic samples with methylation at the SRD5A2 promoter...

Rheumatoid arthritis (RA) is a chronic, progressive autoimmune disease that causes inflammation and destruction of the joints.1-3 It can also affect the eyes, the heart and the lungs and is associated with significant disability and increased mortality. RA is estimated to affect just under 1% of the population aged over 16 years, equating to more than 400,000 people in the UK.4 ▼Baricitinib (Olumiant) and ▼tofacitinib (Xeljanz) were launched in the UK in April 2017 and represent a new therapeutic class of medicines known as targeted synthetic disease modifying antirheumatic drugs...

BACKGROUND: Salvage radiotherapy (SRT) has been successfully used for recurrent prostate cancer after radical prostatectomy; however, the optimal timing of SRT remains controversial. Our objective was to identify the risk factors for disease progression after SRT, with a focus on the pre-SRT prostate-specific antigen (PSA) levels in the modern era of PSA testing. PATIENTS AND METHODS: We performed a retrospective review of 551 consecutive patients who had undergone postradical prostatectomy SRT for recurrent prostate cancer from 2000 to 2013...

Baricitinib (Olumiant™) is an orally-administered, small-molecule, janus-associated kinase (JAK) inhibitor developed by Eli Lilly and Incyte Corporation for the treatment of rheumatoid arthritis (RA), atopic dermatitis and systemic lupus erythematosus. JAKs transduce intracellular signals from cell surface receptors for various cytokines and growth factors involved in inflammation and immune function, suggesting JAK inhibitors may be of therapeutic benefit in inflammatory conditions. In February 2017, baricitinib was approved in the EU, as monotherapy or in combination with methotrexate, for the treatment of moderate to severe active rheumatoid arthritis in adult patients who have responded inadequately to, or who are intolerant to one or more disease-modifying anti-rheumatic drugs (DMARDs)...

PURPOSE: The purpose of this study was to evaluate freedom from biochemical failure (FFBF), freedom from androgen deprivation therapy (FFADT), freedom from distant metastases (FFDM), and overall survival (OS) after adjuvant radiation therapy (ART) versus early salvage radiation therapy (ESRT) in men with prostate cancer and adverse pathologic features (pT3 and/or positive surgical margins). METHODS AND MATERIALS: Of 718 patients consecutively treated with postoperative radiation therapy (RT) for prostate cancer between 1992 and 2013, we retrospectively identified 171 men receiving ART and 230 receiving ESRT (RT delivered at a prostate-specific antigen level ≤0...

OBJECTIVE: Benign prostatic hyperplasia (BPH) is the most common proliferative abnormality of the prostate affecting elderly men throughout the world. Epidemiologic studies have shown that diabetes significantly increases the risk of developing BPH, although whether anti-diabetic medications preventing the development of BPH remains to be defined. We have previously found that stromally expressed insulin-like growth factor 1 (IGF-1) promotes benign prostatic epithelial cell proliferation through paracrine mechanisms...
