ATF2 promotes urothelial cancer outgrowth via cooperation with androgen receptor signaling.

Endocr Connect 2018 Dec;7(12):1397-1408

Department of Pathology & Laboratory Medicine, University of Rochester Medical Center, Rochester, New York, USA.

We investigated the functional role of ATF2, a transcription factor normally activated via its phosphorylation in response to phospho-ERK/MAPK signals, in the outgrowth of urothelial cancer. In both neoplastic and non-neoplastic urothelial cells, the expression levels of androgen receptor (AR) correlated with those of phospho-ATF2. Dihydrotestosterone treatment in AR-positive bladder cancer cells also induced the expression of phospho-ATF2 and phospho-ERK as well as nuclear translocation and transcriptional activity of ATF2.

Immunomodulatory response of layered small intestinal submucosa in a rat bladder regeneration model.

J Biomed Mater Res B Appl Biomater 2018 Dec 6. Epub 2018 Dec 6.

Department of Urology, University of Oklahoma Health Sciences Center, Oklahoma City, Oklahoma 73104.

Based on the hypothesis that bioscaffold permeability is a major factor in determining the outcome of histologically complete and functional bladder regeneration, we evaluated regeneration processes of four-layer porcine small intestinal submucosa (SIS) construct; and compared results between rat bladders augmented with single-layer SIS bioscaffolds. Sprague-Dawley female rats were subjected to hemi-cystectomy followed by anastomosis of a patch of either single- or four-layer porcine SIS. Permeability was analyzed in situ using magnetic resonance imaging (MRI) at post-operative days 7 and 14. Read More

CD4+ T cells induce rejection of urothelial tumors after immune checkpoint blockade.

JCI Insight 2018 Dec 6;3(23). Epub 2018 Dec 6.

Department of Internal Medicine, Division of Oncology.

Immune checkpoint blockade (ICB) provides clinical benefit to a minority of patients with urothelial carcinoma (UC). The role of CD4+ T cells in ICB-induced antitumor activity is not well defined; however, CD4+ T cells are speculated to play a supportive role in the development of CD8+ T cells that kill tumor cells after recognition of tumor antigens presented by MHC class I. To investigate the mechanisms of ICB-induced activity against UC, we developed mouse organoid-based transplantable models that have histologic and genetic similarity to human bladder cancer.

The Role of Glucocorticoid Receptor Signaling in Bladder Cancer Progression.

Cancers (Basel) 2018 Dec 4;10(12). Epub 2018 Dec 4.

Department of Pathology & Laboratory Medicine, University of Rochester Medical Center, Rochester, NY 14642, USA.

Previous preclinical studies have indicated that the activation of glucocorticoid receptor signaling results in inhibition of the growth of various types of tumors. Indeed, several glucocorticoids, such as dexamethasone and prednisone, have been prescribed for the treatment of, for example, hematological malignancies and castration-resistant prostate cancer. By contrast, the role of glucocorticoid-mediated glucocorticoid receptor signaling in the progression of bladder cancer remains far from being fully understood. Read More

DNA replication licensing proteins: Saints and sinners in cancer.

Semin Cancer Biol 2018 Nov 28. Epub 2018 Nov 28.

Cancer Centre, Faculty of Health Sciences, University of Macau, Avenida de Universidade, Taipa, Macau. Electronic address:

DNA replication is all-or-none process in the cell, meaning, once the DNA replication begins it proceeds to completion. Hence, to achieve maximum control of DNA replication, eukaryotic cells employ a multi-subunit initiator protein complex known as "pre-replication complex or DNA replication licensing complex (DNA replication LC). This complex involves multiple proteins which are origin-recognition complex family proteins, cell division cycle-6, chromatin licensing and DNA replication factor 1, and minichromosome maintenance family proteins.

Morphological and Immunohistochemical Biomarkers in Distinguishing Prostate Carcinoma and Urothelial Carcinoma: A Comprehensive Review.

Int J Surg Pathol 2018 Dec 3:1066896918814198. Epub 2018 Dec 3.

1 University Hospital, Foggia, Italy.

The differential diagnosis between high-grade prostate carcinoma and infiltrating urothelial carcinoma (UC) in transurethral resection prostate specimens as well as cystoprostatectomy specimens may often be challenging due to morphologic and clinical overlap of the 2 entities. Such distinction has critical therapeutic and staging consequences, yet it is hampered by both issues in morphology and by the low accuracy rates of single immunohistochemical markers, as reported in literature. This review aims to provide a comprehensive analysis of the available morphological and immunohistochemical parameters, which may allow to discriminate between prostate carcinoma and urothelial carcinoma in the proper clinical context and to discuss their diagnostic applications in daily practice.

Potential role of the 3-mercaptopyruvate sulfurtransferase (3-MST)-hydrogen sulfide (HS) pathway in cancer cells.

Pharmacol Res 2018 Nov 27. Epub 2018 Nov 27.

Chair of Pharmacology, Faculty of Science and Medicine, University of Fribourg, Fribourg, Switzerland. Electronic address:

Hydrogen sulfide (HS), produced by various endogenous enzyme systems, serves various biological regulatory roles in mammalian cells in health and disease. Over recent years, a new concept emerged in the field of HS biology, showing that various cancer cells upregulate their endogenous HS production, and utilize this mediator in autocrine and paracrine manner to stimulate proliferation, bioenergetics and tumor angiogenesis. Initial work identified cystathionine-beta-synthase (CBS) in many tumor cells as the key source of HS. Read More

Fluorescence in situ hybridization in 1 mL of selective urine for the detection of upper tract urothelial carcinoma: a feasibility study.

Med Oncol 2018 Nov 29;36(1):10. Epub 2018 Nov 29.

Department of Urology, Amsterdam University Medical Centers, University of Amsterdam, Meibergdreef 9 G4-223, 1105AZ, Amsterdam, The Netherlands.

Kidney-sparing surgery of upper tract urothelial carcinoma (UTUC) requires a stringent follow-up with frequent ureteroscopies. Triage testing could reduce the number of follow-up ureteroscopies and hence minimize the invasiveness of follow-up. The use of urine-based markers for triage seems appealing but should be feasible with selective urine from outpatient cystoscopy to maximize the reduction of invasiveness. Read More

Introduction And Objectives: We previously reported that elevated precystectomy serum levels of epithelial tumor markers predict worse oncological outcome in patients with invasive bladder cancer (BC). Herein, we evaluated the effect of neoadjuvant chemotherapy (NAC) on elevated tumor marker levels and their association with oncological outcomes.

Methods: Under IRB approval, serum levels of Carbohydrate Antigen 125 (CA-125), Carbohydrate Antigen 19-9 (CA 19-9) and Carcinoembryonic Antigen (CEA) were prospectively measured in 480 patients with invasive BC from August 2011 through December 2016. Read More

Suppression of long non-coding RNA UCA1 inhibits proliferation and invasion and induces apoptosis in human lung cancer cells.

Eur Rev Med Pharmacol Sci 2018 Nov;22(21):7274-7281

Department of The First Thoracic Surgery, Shengjing Hospital of China Medical University, Shenyang, Liaoning Province, People's Republic of China.

Objective: Lung cancer is one of the deadliest cancers responsible for significant mortality and morbidity across the globe. The unavailability of efficient treatments, lack of reliable biomarkers and potent therapeutic targets, limit the treatment of lung cancer. In this study, we explored the potential of long non-coding RNA (lncRNA) urothelial carcinoma-associated 1 (UCA1) as the therapeutic target for lung cancer. Read More

Abdominal Imaging Division, UT Southwestern University Hospitals, 5323 Harry Hines Boulevard, Dallas, TX 75390-8827, USA.

Hematuria evaluation remains a common problem, particularly in patients who smoke and are at risk for urothelial tumors. Lifetime surveillance of the urothelium is often required once urothelial cancer is diagnosed. Computed tomography urography (CTU) has exquisite sensitivity and specificity for identification of renal and urothelial lesions. Read More
