Tumor-derived exosomal BCYRN1 activates WNT5A/VEGF-C/VEGFR3 feedforward loop to drive lymphatic metastasis of bladder cancer.

Background: Patients with lymph node (LN) metastatic bladder cancer (BCa) present with extremely poor prognosis. BCa-derived exosomes function as crucial bioactive cargo carriers to mediate the signal transduction in tumor microenvironment triggering tumor metastasis. However, the mechanisms underlying exosome-mediated LN metastasis in BCa are unclear.

Repeat periods of electrical stimulation prolong the modulation of the micturition reflex in the rat.

Aims: The aim of this study was to determine if the duration of the micturition reflex modulation could be prolonged by repeated periods of afferent stimulation in the decorticated rat.

Methods: Eighteen female Sprague-Dawley rats were used for the study, 10 for intravesical electrical stimulation (IVES), and 8 for Ano-genital pudendal afferents stimulation. Repeated constant flow cystometries were performed with body-warm saline (0.

Muscarinic cholinergic signaling and overactive bladder-like symptoms associated with invasive bladder cancer.

The objective of the present study was to explore the association between muscarinic cholinergic signaling and urothelial bladder tumors. Possible associations among overactive bladder (OAB) symptoms and bladder tumors were retrospectively investigated using a multicenter Chinese database with prospectively collected data since 2010. Firstly, it was demonstrated that OAB symptoms, such as urgency, were more severe in patients with invasive bladder cancer and were associated with a reduced prognosis.

Potential use of chymotrypsin-like proteasomal activity as a biomarker for prostate cancer.

Although it is the most widely used biomarker for prostate cancer, the use of prostate specific antigen (PSA) is controversial due to its limitations in specificity and sensitivity. The proteasome is a complex associated with cell proliferation and apoptosis, and the abnormity of these processes may lead to tumor occurrence. Previous studies have reported that proteasomal activity is associated with cancer progression and can be used in risk stratification.

A phase 3, double-blind, randomized placebo-controlled efficacy and safety study of abiraterone acetate in chemotherapy-naïve patients with mCRPC in China, Malaysia, Thailand and Russia.

Objective: This double-blind, placebo-controlled phase 3 study was designed to compare efficacy and safety of abiraterone acetate + prednisone (abiraterone) to prednisone alone in chemotherapy-naïve, asymptomatic or mildly symptomatic metastatic castration-resistant prostate cancer (mCRPC) patients from China, Malaysia, Thailand and Russia.

Methods: Adult chemotherapy-naïve patients with confirmed prostate adenocarcinoma, Eastern Cooperative Oncology Group (ECOG) performance status (PS) grade 0-1, ongoing androgen deprivation (serum testosterone <50 ng/dL) with prostate specific antigen (PSA) or radiographic progression were randomized to receive abiraterone acetate (1000 mg, QD) + prednisone (5 mg, BID) or placebo + prednisone (5 mg, BID), until disease progression, unacceptable toxicity or consent withdrawal. Primary endpoint was improvements in time to PSA progression (TTPP).

Prospective Study of CRMP4 Promoter Methylation in Prostate Biopsies as a Predictor For Lymph Node Metastases.

Background: For patients with prostate cancer (PCa), the presence of pelvic lymph node metastasis (LNM) is a strong predictor of poor outcome. However, the approaches with promising sensitivity and specificity to detect LNM are still lacking. We investigated the value of collapsin response mediator protein 4 (CRMP4) promoter methylation in biopsies as a predictor for LNM.

Effects of botulinum toxin A injections in spinal cord injury patients with detrusor overactivity and detrusor sphincter dyssynergia.

Objective: To evaluate the safety and effect of botulinum toxin A injection in the detrusor and external urethral sphincter in male patients with detrusor overactivity (DO) and detrusor external sphincter dyssynergia (DESD) secondary to spinal cord injury.

Methods: A multicentre trial was conducted from June 2012 to August 2015. A total of 65 spinal cord injury patients with DO and DESD participated in the study.

Plasma proteasomal chymotrypsin-like activity correlates with prostate cancer progression.

Previously, we demonstrated that inhibition of proteasomal chymotrypsin-like (CT-like) activity in human prostate cancer (PCa) PC-3 cultures and PC-3 xenografts results in accumulation of ubiquitinated proteins, followed by induction of cell death. Studies have shown that plasma CT-like proteasomal activity may be a powerful biomarker for risk stratification in hematologic malignancies. We hypothesized that circulating proteasomes could also be used to stratify risk for patients with PCa.

PSA density improves the rate of prostate cancer detection in Chinese men with a PSA between 2.5-10.0 ng ml (-1) and 10.1-20.0 ng ml (-1) : a multicenter study.

Chinese men should have a higher prostate-specific antigen (PSA) "gray zone" than the traditional value of 2.5-10.0 ng ml-1 since the incidence of prostate cancer (PCa) in Chinese men is relative low.

Cystitis glandularis: A controversial premalignant lesion.

Cystitis glandularis (CG) has been hypothesized as a potential precursor of adenocarcinoma, although this remains controversial. The present study reports data accumulated from 166 cases of cystitis glandularis with follow-up periods ranging between 0.5 and 17 years.

MLN2238 synergizes BH3 mimetic ABT-263 in castration-resistant prostate cancer cells by induction of NOXA.

Patients undergoing androgen blockade therapy develop castration-resistant prostate cancer (CRPC), which is associated with Bcl-2 upregulation and results in disease progression and death. In recent years, promising therapeutic agents, such as the BH3-only mimetic ABT-263 and proteasome inhibitors, have been developed and widely evaluated against a broad spectrum of cancer types, including prostate cancer, alone or in combination with other chemotherapeutic agents. In this study, the antitumor efficacy of ABT-263 and MLN2238 were evaluated as single agents and in combination in four CRPC cell lines: PC3, C4-2B, C4-2, and DU145.

Percent free prostate-specific antigen does not improve the effectiveness of prostate cancer detection in Chinese men with a prostate-specific antigen of 2.5-20.0 ng/ml: a multicenter study.

The prostate-specific antigen (PSA) "gray zone" in Chinese men is likely higher than the traditional value (2.5-10.0 ng/ml) since the incidence of prostate cancer in Chinese men is relative low.
