miRNAs are a class of small-noncoding RNAs capable of negatively regulating gene expression. Here, we found that miR-195 is down-regulated in human bladder cancer tissue versus normal adjacent tissue. To better characterize the role of miR-195 in bladder cancer, we conducted gain of function analysis by transfecting bladder cancer cell line T24 with(More)
OBJECTIVE Diabetes is associated with increased risk of cancer at several sites, but its association with risk of bladder cancer is still controversial. We examined this association by conducting a systematic review and meta-analysis of cohort studies. METHODS Studies were identified by searching PubMed, EMBASE, Scopus, Web of Science, Cochrane register,(More)
Very recent studies have reported that chemically synthesized small duplex RNAs complementary to the promoters of target genes can activate gene expression in different cancer cell lines. Such dsRNA have been referred to as saRNA for small activating RNA. The present study was conducted to evaluate the potential of p21(WAF1/Cip1) (p21) induction by small(More)
OBJECTIVE Previous studies on the association between tea consumption and bladder cancer risk have only illustrated contradictory results. The role of tea in bladder carcinogenesis still remains conflicting. In order to illustrate the potential relationship between tea consumption and bladder cancer, a meta-analysis of case-control and cohort studies was(More)
Resveratrol, a naturally occurring polyphenolic antioxidant compound present in grapes and red wine, has been reported to hold various biochemical responses. In this preliminary study, we evaluate the chemopreventive potential of resveratrol against bladder cancer and its mechanism of action. Treatment of bladder cancer cells with resveratrol resulted in a(More)
Frequent downregulation of microRNA-449a (miR-449a) was detected in 14 human bladder cancer tissues. The restoration of miR-449a inhibited cell growth and induced G1-phase arrest in T24 and 5637 human bladder cancer cells. CDK6 and CDC25a were downregulated after miR-449a treatment, resulting in the functional accumulation of the pocket proteins Rb and(More)
It is well known that the garlic-derived organosulfur compounds (OSCs) are effective to inhibit a variety of human cancers such as prostate, breast, colon, skin, lung, and bladder cancers. Herein, the pro-apoptotic effects of diallyl trisulfide (DATS), one of garlic-derived OSCs, on T24 bladder cancer cells were investigated. The results demonstrated that(More)
To investigate the effect of the vitamin D receptor (VDR) Fok I Bsm I Dde I Apa I Taq I polymorphism on the clinical presentation of calcium urolithiasis, 464 patients with urolithiasis and 450 age- and sex-matched healthy controls were recruited from The First Affiliated Hospital of Zhejiang University between January 2010 and March 2011. Five SNPs of VDR(More)
microRNAs (miRNAs), small non-coding RNAs, have emerged as key regulators of a large number of genes. The present study aimed to explore novel biological functions of miR-330 in the human prostate cancer cell lines DU145 and PC3. We confirmed that miR-330 was downregulated and inversely correlated with specificity protein 1 (Sp1) expression. Overexpression(More)
Recent studies have reported that chemically synthesized small duplex RNAs complementary to promoters of target genes can specifically induce gene expression in several cancer cell lines. Such dsRNA, referred to as small activating RNA (saRNA), are involved in the recently described phenomenon called RNA activation (RNAa). Recent findings show that saRNA(More)
