Many different microRNAs existed in nephrotic syndrome patients, and they may be involved in nephrotic syndrome occurrence. In order to further clarify miRNAs expression changes in nephrotic syndrome patients and their correlation with clinical features, this study investigated differential microRNA expression in the peripheral serum of patients with nephrotic syndrome and analyzed the correlat...
Paclitaxel is a mainstay of treatment for many solid tumors, and frequently, clinical outcome is influenced by paclitaxel sensitivity. Despite this, our understanding of the molecular basis of paclitaxel response is incomplete. Recently, it has been shown that microRNAs (miRNAs) influence messenger RNA (mRNA) transcriptional control and can contribute to human carcinogenesis. In the present stu...
Expression of brain-derived neurotrophic factor (BDNF) is developmentally regulated in prefrontal cortex (PFC). The underlying molecular mechanisms, however, remain unclear. Here, we explore the role of microRNAs (miRNAs) as post-transcriptional inhibitors of BDNF. A sequential approach involving in silico, miRNA microarray, in situ hybridization and qRT-PCR studies identified a group of 10 can...
We evaluated micro (mi) RNA-mediated regulation of BAFF expression in fibroblasts using two concomitant models: (i) synovial fibroblasts (FLS) isolated from healthy controls (N) or Rheumatoid Arthritis (RA) patients; (ii) human dermal fibroblasts (HDF) isolated from healthy controls (N) or Systemic Sclerosis (SSc) patients. Using RT-qPCR and ELISA, we first showed that SScHDF synthesized and re...
OBJECTIVE This study aimed to identify a set of endometrioid endometrial carcinoma EEC-associated microRNAs (miRNAs) in tissue and plasma, and evaluate their clinical significance. METHODS A set of EEC-associated miRNAs in tissue and plasma was identified by next-generation sequencing (NGS), which could enable in-depth characterization of the global repertoire of miRNAs. RESULTS NGS identif...
Inactivation of the von-Hippel Lindau (VHL) tumor suppressor gene occurs in 90% of human clear cell renal cell carcinomas (ccRCC) and leads to the stable expression of the hypoxia-inducible factors HIF1α and HIF2α. The constitutive expression of HIF1α in a majority of VHL-deficient tumors is counterintuitive, given that HIF1α functions as a tumor suppressor in ccRCC, whereas HIF2α clearly enhan...
RATIONALE Transforming growth factor (TGF)-β was linked to abnormal vessel function and can mediate impairment of endothelial angiogenic responses. Its effect on microRNAs and downstream targets in this context is not known. OBJECTIVE To study the role of microRNAs in TGF-β-mediated angiogenic activity. METHODS AND RESULTS MicroRNA profiling after TGF-β treatment of endothelial cells identi...
Skin aging is a complex biological process leading to multiple functional defects in the different structure of skin tissues. Epidermal especially characterized by an alteration tissue renewal associated impairment keratinocytes differentiation process. We have previously reported that microRNA miR-30a over-expressed aged epidermis and we shown organotypic models this induction impairs epiderma...
BACKGROUND MicroRNA (miRNA) expression is known to be deregulated in ovarian carcinomas. However, limited data is available about the miRNA expression pattern for the benign or borderline ovarian tumors as well as differential miRNA expression pattern associated with histological types, grades or clinical stages in ovarian carcinomas. We defined patterns of microRNA expression in tissues from n...
The presenilin-mediated Notch1 cleavage pathway plays a critical role in controlling pancreatic beta cell fate and survival. The aim of the present study was to investigate the role of Notch1 activation in glucotoxicity-induced beta cell impairment and the contributions of miR-375, miR-30a, and miR-34a to this pathway. We found that the protein levels of presenilins (PSEN1 and PSEN2), and NOTCH...
