SETD4 inhibits prostate cancer development by promoting H3K27me3-mediated NUPR1 transcriptional repression and cell cycle arrest.

The suppressor of variegation enhancer of zeste-trithorax (SET) domain methyltransferases have been reported to function as key regulators in multiple tumor types by catalyzing histone lysine methylation. Nevertheless, our understanding on the role of these lysine methyltransferases, including SETD4, in prostate cancer (PCa) remains limited. Hence, the specific role of SETD4 in PCa was investigated in this study.

BAP1-Related ceRNA (NEAT1/miR-10a-5p/SERPINE1) Promotes Proliferation and Migration of Kidney Cancer Cells.

Background: is an important tumor suppressor involved in various biological processes and is commonly lost or inactivated in clear-cell renal cell carcinoma (ccRCC). However, the role of the BAP1-deficient tumor competing endogenous RNA (ceRNA) network involved in ccRCC remains unclear. Thus, this study aims to investigate the prognostic BAP1-related ceRNA in ccRCC.

Objective: To investigate the application of a simplified technique for reconstruction of vesicourethral support (RVUS) in laparoscopic radical prostatectomy (LRP).

Methods: From January 2017 to August 2019, 122 patients with localized prostate cancer underwent extraperitoneal LRP, 65 with RVUS (the RVUS group) and 57 without RVUS (the non-RVUS group). We compared the operation time, intraoperative blood loss, rate of pelvic lymph node dissection, neurovascular bundle sparing, incidence of urethrovesical anastomotic urinary leakage (UVAUL), postoperative urinary continence, postoperative hospital stay, intraperitoneal drainage tube removal time, and urethral catheter removal time between the two groups of patients.

Methods: Twenty normal healthy male SD rats were equally randomized into an HRW and a control group, the former given HRW (1.2 ppm) and the latter normal saline, both intragastrically at 2 ml/d for 9 months.

Role of the functional variant (-652T>G) in the XRCC4 promoter in prostate cancer.

Several genes encoding DNA repair molecules have been proposed as cancer-susceptibility genes. Many studies have suggested that SNPs in XRCC4 could be implicated in altering the risk of prostate cancer (PCa). We examined the role of the functional variant (-652T>G) in the XRCC4 promoter in PCa.

Differential expression of the Wnt/β-catenin pathway in the genital tubercle (GT) of fetal male rat following maternal exposure to di-n-butyl phthalate (DBP).

Di-n-butyl phthalate (DBP) is one of the most abundantly produced endocrine disruptors that leaches out from polyvinyl chloride plastics and can cause hypospadias in male rats during maternal exposure. The objective of this study was to first explore the roles of Wnt/β-catenin pathway in the fetal rat genital tubercle (GT) following in-utero exposure to DBP. Timed-pregnant rats were given DBP by gastric intubation at a dose of 750 mg/kg body weight (bw)/day from gestation day (GD) 14 to GD18 to establish a rat model of hypospadias.

An update analysis of two polymorphisms in encoding ribonuclease L gene and prostate cancer risk: involving 13,372 cases and 11,953 controls.

Encoding ribonuclease L (RNASEL) is a ubiquitously expressed latent endoribonuclease involved in the mediation of antiviral and pro-apoptotic activities of the interferon-inducible 2-5A system. Although the relationship between RNASEL gene polymorphisms and prostate cancer (PCa) risk has been widely reported, results were somewhat controversial and underpowered. Now, we performed an update analysis of 14 publications evaluating the association between RNASEL R462Q and D541E polymorphisms and PCa risk.

[TRAIL gene polymorphism and genetic susceptibility to prostate cancer in the Chinese Han population of Nanjing].

Objective: To investigate the correlation between the polymorphism of the tumor necrosis factor-related apoptosis inducing ligand (TRAIL) and the genetic susceptibility to prostate cancer (PCa) in the Chinese Han population in Nanjing.

Methods: We performed a case control study on 187 cases of PCa and 237 cancer-free healthy controls. Peripheral blood genome DNA was extracted from the subjects for analysis of the polymorphism of the TRAIL-716 locus by polymerase chain reaction-ligase detection reaction (PCR-LDR).

[Proteomic analysis of the testis and differential expression of Annexin A3 in hypospadiac rats].

Objective: To investigate the effect of in utero exposure to di-n-butyl phthalate (DBP) on the protein expression in the penile tissue of hypospadiac rats, isolate and identify differentially expressed proteins, and determine the role of the differential expression of Annexin A3 in the development of hypospadia in the rat offspring after maternal exposure to DBP.

Methods: Twenty pregnant SD rats were randomly assigned to an experimental group, intragastrically administered DBP at 800 mg/kg, and a control group, given soybean oil at 5 ml/kg, both for 5 days. Three days after birth, the penises of the newborn rats were removed, and the total protein extracted for 2D-electrophoretic separation and image analysis.

Association between polymorphisms of TP53 and MDM2 and prostate cancer risk in southern Chinese.

Alterations in the TP53 and MDM2 genes appear to be important in the development of many human tumors, but evidence is conflicting on associations between polymorphisms in these genes and risk of prostate cancer (PCa). The influence of TP53 codon 72, MDM2 SNP309, and MDM2 C1797G polymorphisms in southern Chinese PCa patients was investigated. In the comparison of genotype distributions of TP53 codon 72 between cases and controls, the adjusted odds ratios for PCa associated with the Pro/Pro, Arg/Pro, and Arg/Arg genotypes were 1.

Introduction: Alterations in P53 and murine double minute 2 (MDM2) genes appear to be important in the development of many human tumors. We investigated the potential prognostic roles of p53 codon 72 and MDM2 309 and 1797 polymorphisms in prostate cancer after radical prostatectomy.

Patients And Methods: Fifty southern Chinese with prostate cancer undergoing radical prostatectomy were included in this study.

Review and pooled analysis of studies on -607(C/A) and -137(G/C) polymorphisms in IL-18 and cancer risk.

Interleukin-18 (IL-18) is a pleiotropic, pro-inflammatory cytokine with dual effects on tumor development and progression. The -607(C/A) and -137(G/C) polymorphisms in IL-18 gene region have been implicated in cancer risk; however, data from published studies with individually low statistical power are conflicting. To clarify the role of IL-18 -607(C/A) and -137(G/C) genotype in global cancer, we examined all the available published studies through a pooled analysis approach.

A functional polymorphism in MSMB gene promoter is associated with prostate cancer risk and serum MSMB expression.

Background: To explore the reported association of SNP marker rs10993994 with prostate cancer identified by two independent in two genome-wide association studies (GWAS) further, we performed a case-control study in southern Chinese Han population. Consequently, we detected the serum levels of MSMB expression with different genotypes in the cases and controls to characterize the functional consequences of rs10993994.

Materials And Methods: Two hundred fifty-one prostate cancer and 258 control subjects were included in the cancer association study and 90 serum samples were used to test the expression of the MSMB by Enzyme-linked immunosorbent assay (ELISA).

VEGFA +936C>T polymorphism and cancer risk: a meta-analysis.

Vascular endothelial growth factor A (VEGF-A), a major driver of physiological and pathological angiogenesis, plays important roles in the etiology and metastasis of cancers. The +936C>T polymorphism in the 3'-untranslated region of the VEGFA gene has been implicated in cancer risk and is related to VEGF-A protein production; however, published data have been conflicting. To derive a more precise estimation of the relationship, a meta-analysis was performed of 13,293 cancer cases and 12,308 control subjects from 29 published case-control studies.
