SPHK1/S1PR1/PPAR-α axis restores TJs between uroepithelium providing new ideas for IC/BPS treatment.

Interstitial cystitis/bladder pain syndrome (IC/BPS) represents a chronic, aseptic inflammatory bladder condition with an unclear etiology and few therapeutic options. A composite barrier structure composed of the uroepithelium and glycosaminoglycan layer forms on the bladder's inner surface to block urine and other harmful substances. Dysfunction of this barrier may initiate the pathogenesis of IC/BPS.

Identification of an immune subtype-related prognostic signature of clear cell renal cell carcinoma based on single-cell sequencing analysis.

Background: There is growing evidence that immune cells are strongly associated with the prognosis and treatment of clear cell renal cell carcinoma (ccRCC). Our aim is to construct an immune subtype-related model to predict the prognosis of ccRCC patients and to provide guidance for finding appropriate treatment strategies.

Methods: Based on single-cell analysis of the GSE152938 dataset from the GEO database, we defined the immune subtype-related genes in ccRCC.

Efficacy of peripheral electrical nerve stimulation on improvements of urodynamics and voiding diary in patients with neurogenic lower urinary tract dysfunction: a systematic review and meta-analysis.

Background: Peripheral electrical nerve stimulation is a routinely recommended treatment for non-neurogenic overactive bladder but has not been approved for patients with neurogenic lower urinary tract dysfunction (NLUTD). This systematic review and meta-analysis was to elucidate the efficacy and safety of electrostimulation and thus provide firm evidence for treating NLUTD.

Materials And Methods: We systematically performed the literature search through PubMed, Web of Science, and Cochrane Library databases in March 2022.

Neoadjuvant Chemohormonal Therapy in Prostate Cancer Before Radical Prostatectomy: A Systematic Review and Meta-Analysis.

Objective: This meta-analysis was to investigate the effects of neoadjuvant chemohormonal therapy (NCHT) on patients with prostate cancer (PCa) before radical prostatectomy (RP) and attempt to provide meaningful evidence.

Methods: A systematic search was performed using the PubMed, Web of Science, and Cochrane Library databases in February 2022 based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The relevant studies were critically screened and we extracted the data of demography, postoperative pathology, and survival to calculate the pooled effect sizes.

Management and Follow-Up Practices of Women With Recurrent Stress Urinary Incontinence Following Transobturator Mid-urethral Synthetic Sling Procedure: A 6-Year Retrospective Monocentric University-Based Study.

The purpose of this study is to evaluate the efficacy of management and follow-up practices in repeat retropubic mid-urethral synthetic sling (MUS) procedure after transobturator tape/tension-free vaginal tape-obturator (TOT/TVT-O) failure, and to clarify the possible etiology of recurrent stress urinary incontinence. The charts of all women patients who underwent tension-free vaginal tape (TVT) slings after previous failed transobturator MUS procedures between February 2012 and November 2018 at a single center were reviewed retrospectively. The transperineal ultrasound was performed to assess the pre-operative or post-operative urethral mobility and location of the slings.

Combined Signature of the Urinary Microbiome and Metabolome in Patients With Interstitial Cystitis.

Interstitial cystitis (IC) is a clinical syndrome characterized by frequency, urgency, and bladder pain or pelvic pain; however, the underlying pathophysiological mechanisms and diagnostic markers are unknown. In this study, microbiome and metabolome analysis were used to explain the urine signatures of IC patients. Urine samples from 20 IC patients and 22 control groups were analyzed by using 16S rRNA sequence and liquid chromatography coupled with mass spectrometry.

Nrf2 Pathway Ameliorates Bladder Dysfunction in Cyclophosphamide-Induced Cystitis via Suppression of Oxidative Stress.

Objective: To investigate the protective effect and molecular mechanism of nuclear factor E2-related factor 2 (Nrf2) pathway in interstitial cystitis (IC).

Methods: We established a mouse model of IC by cyclophosphamide (CYP) in wild-type mice and Nrf2 gene knockout mice. We examined the histological and functional alterations, the changes of oxidative stress markers, and the expression of the antioxidant genes downstream of Nrf2 pathway.

Primary bladder mucosa-associated lymphoid tissue lymphoma: A case report and literature review.

Introduction: Primary bladder mucosa-associated lymphoid tissue (MALT) lymphoma is a rare tumor. To date, the PubMed database contains only 39 English articles covering 63 cases of primary bladder MALT lymphoma. Herein, we report a case of this disease and review the current literature.

Author Correction: Down-regulated GATA-1 up-regulates interferon regulatory factor 3 in lung adenocarcinoma.

A correction to this article has been published and is linked from the HTML and PDF versions of this paper. The error has been fixed in the paper.

Preclinical trial of the multi-targeted lenvatinib in combination with cellular immunotherapy for treatment of renal cell carcinoma.

Lenvatinib is an oral, multi-targeted tyrosine kinase inhibitor of vascular endothelial growth factor receptors 1-3, fibroblast growth factor receptors 1-4, platelet-derived growth factor receptor β, RET and KIT. Cellular immunotherapy has the potential to be a highly targeted treatment, with low toxicity to normal tissues and a high capacity to eradicate tumor tissue. The present study assessed the safety, maximum tolerated dose (MTD) and preliminary antitumor activity of lenvatinib and cellular immunotherapy in a murine model of renal cell carcinoma (RCC).

Down-regulated GATA-1 up-regulates interferon regulatory factor 3 in lung adenocarcinoma.

Interferon regulatory factor 3 (IRF-3) is widely known for its prompt response against viral infection by activating the interferon system. We previously reported that E2F1, Sp1 and Sp3 regulated transcriptional activity of IRF-3. Recently, different expression patterns of IRF-3 were found in lung cancer, leading to the alternation of the immunomodulatory function in tumorigenesis.

Integrin-Linked Kinase Improves Functional Recovery of Diabetic Cystopathy and Mesenchymal Stem Cell Survival and Engraftment in Rats.

Objectives: Diabetic cystopathy (DCP), characterized by peripheral neuropathy-associated bladder dysfunction, is a common urinary complication in patients with diabetes (~80%). Bone marrow mesenchymal stem cell (BMMSC) transplantation, a new and emerging regenerative therapy, provides a curative option for DCP. However, the application of this therapy is limited by the low survival rate and engraftment of transplanted stem cells.

RETRACTED: Sulforaphane restores oxidative stress induced by di-N-butylphthalate in testicular Leydig cells with low basal reactive oxygen species levels.

Objective: To investigate the role and therapeutic potential of Nuclear factor erythroid-related factor 2 (Nrf2) in oxidative stress induced by di-N-butylphthalate (DBP) in testicular Leydig cells.

Materials And Methods: Levels of reactive oxygen species (ROS) and Nrf2 in testicles from offspring of mice fed with DBP were studied. Basal ROS and Nrf2 level in mouse TM3 testicular Leydig cells were studied.
