Western blot analysis was employed to detect expression of Bcl-2, Bax, Caspase-3 and STAT3 proteins. Results: We revealed that miR-124 was significantly up-regulated in a mice model of MI and in neonatal rat...

... enhanced cell proliferation in vitro and promoted tumor growth in vivo . Furthermore, overexpression of TPPP3 remarkably promoted NSCLC cell migration and invasion along with the upregulation of Twist1 both in vitro and in vivo . Further investigations showed that activation of STAT3 was required for TPPP3...

...Chong Xu; Guo Dong Liu; Le Feng; Cong Hui Zhang; Fang Wang Background/Aims: Recently, we observed an increase in O-GlcNAc (O-linked-ß-N-acetylglucosamine) modification, and signal transducer and activator of transcription proteins 3 (STAT3) expression in primary retinal vascular endothelial cells...

... and activator of the transcription 3 (STAT3), and thus aggravated H 2 O 2 -induced the reduction of Bcl-2 protein. Conclusions: Pre-treatment with melatonin protects c-kit+ CPCs against oxidative stress-induced damage via downregulation of miR-98 and thereby increasing STAT3, representing a potentially new...

...-oxygenation (H/R) without or with PKC-ε or STAT3 gene knock-down in the absence or presence of remote time hypoxia preconditioning (HPC). Results: Diabetic rats displayed larger post-ischemic myocardial infarct size and higher troponin-I release with concomitant cardiac PKC-ԑ overexpression and activation...

... correlated with STK35 expression. The mRNA expression of STK35 was repressed by STAT3 small interfering RNA (siRNA), but not by siRNA of STAT4, STAT5A or STAT6. A luciferase reporter assay further demonstrated that STAT3 transcriptionally regulated STK35 expression. A chromatin immunoprecipitation (ChIP...

... was performed to examine the phosphorylation and protein expression of extracellular signaling-regulated kinase 1/2 (ERK1/2), signal transducer and activator of transcription 3 (Stat3), 3-phosphoinositide dependent protein kinase-1 (PDK1) and transcription factor SP1. QRT-PCR was used to examine the mRNA levels...

... transducer and activator of transcription 3 (Stat3), SP1, forkhead box O3a (FOXO3a), and insulin-like growth factor (IGF)-IGF binding protein 1 (IGFBP1). The expression of IGFBP1 mRNA was measured by quantitative real time PCR (qRT-PCR). Silencing of FOXO3a and IGFBP1 were examined by siRNA procedures...

... cause of acute renal failure, renal fibrosis and obstructive nephropathy. However, the underlying molecular mechanisms remain ill-defined. Here, we addressed this question. Methods: Expression of TGFβ1, Snail, and phosphorylated Stat3 was examined by immunohistochemistry in the kidney after induction...

...Xiao-Ping Hu; Qian Xie; Chao-Feng Chen; Wei Zhang; Bo Yu Objective: This study aimed to explore the effects of STAT3 targeting by let-7a on T-cell proliferation and IFN-γ secretion in psoriasis. Methods: From January 2013 to January 2015, 40 patients with psoriasis (psoriasis group) and 38...

... expression but increased E-cadherin expression in Hep2 cells. In the EMT signalling pathway, TRPP2 siRNA significantly decreased Smad4, STAT3, SNAIL, SLUG and TWIST expression in Hep2 cells. Conclusion: We revealed a previously unknown function of TRPP2 in cancer development and a TRPP2-dependent mechanism...

... effect of miRNA-410 on 3'UTR of STAT3 mRNA. Results: We found that the expression level of miR-410 in T cells of SLE patients was decreased comparing to that in healthy controls, whereas overexpression of miR-410 significantly reduced the expression levels of IL-10. Furthermore, miR-410 suppresses...

... and that the inhibitory effects exerted by hypoxia on apoptosis were attenuated by inhibitors of PDGF beta. Moreover, PDGF-B inhibited apoptosis in a dose-dependent manner by stimulating the phosphorylation of both Akt and Stat3, and the PI3K/AKT pathway serves as an up-stream participant in the Stat3 activation...

...′UTR mutant of RUNX1 reversed the suppressive effect of miR-302b. Furthermore, miR-302b overexpression led to the inactivation of the STAT3 signaling pathway in EOC cells and inhibited tumor growth in a xenograft mouse model. Conclusions: MiR-302b functions as a tumor suppressor in EOC by targeting...

... regarded as an oncomiR in the development of cancer. However, its potential role in cardiomyocytes has not been exploited. The aim of this study is to investigate the role of miR-17-5p in I/R-I and the underlying mechanism through targeting Stat3, a key surviving factor in cardiomyocytes. Methods: MTT (3...
