Trefoil factor 3 (TFF3) reconstructs the epithelial barrier by stimulating epithelial cell migration and proliferation, and significantly contributes to intestinal mucosal damage and healing. In a previous study, TFF3 was identified as a novel target of microRNA-7-5p (miR-7-5p). The aim of the present study was to investigate the roles and mechanisms of miR-7-5p in the proliferation and migration of intestinal epithelial cells. Reverse transcription-quantitative polymerase chain reaction (RT-qPCR) was performed to determine the expression level of miR-7-5p in the experimental groups...

Circular RNAs (circRNAs), a class of widespread endogenous RNAs, play crucial roles in diverse biological processes and are potential biomarkers in diverse human diseases and cancers. Cerebellar degeneration-related protein 1 antisense RNA (CDR1as), an oncogenic circRNA, is involved in human tumorigenesis and is dysregulated in hepatocellular carcinoma (HCC). However, the molecular mechanisms underlying CDR1as functions in HCC remain unclear. Here, we explored the functions of CDR1as and searched for CDR1as-regulated proteins in HCC cells...

Sorafenib remains the only approved drug for treating patients with advanced hepatocellular carcinoma (HCC). However, the therapeutic effect of sorafenib is transient and patients invariably develop sorafenib resistance (SR). Recently, TYRO3, a member of the TAM family of receptor tyrosine kinases, was identified as being aberrantly expressed in a significant proportion of HCC, however its role in SR is unknown. In this study, we generated two functionally distinct sorafenib resistant human Huh-7 HCC cell lines, in order to identify new mechanisms to abrogate acquired SR, as well as new potential therapeutic targets in HCC...

Hundreds of circular RNAs (circRNAs) are highly abundant in mammalian brain, with oftentimes conserved expression. Here, we show that the circRNA Cdr1as is massively bound by miR-7 and miR-671 in the human and mouse brain. When the Cdr1as locus was removed from the mouse genome, knockout animals displayed impaired sensorimotor gating, a deficit in the ability to filter out unnecessary information associated with neuropsychiatric disorders. Electrophysiological recordings revealed dysfunctional synaptic transmission...

The 40,000 neurons of the medulla, the largest visual processing center of the Drosophila brain, derive from a sheet of neuroepithelial cells. During larval development, a wave of differentiation sweeps across the neuroepithelium, converting neuroepithelial cells into neuroblasts that sequentially express transcription factors specifying different neuronal cell fates. The switch from neuroepithelial cells to neuroblasts is controlled by a complex gene regulatory network and is marked by the expression of the proneural gene l'sc...

BACKGROUND: Although great efforts have been paid on identification of genetic predisposition in the inherited retinal disease (IRD), genetic causes of a large proportion of patients remain a mystery. This dilemma makes us attempt to speculate that genetic components other than coding genes might be an additional pool predisposing IRD. In this study, we aim to perform a mutational screening in a large cohort of IRD patients with a particular focus on retina-specific or abundant microRNAs (miRs)...

Aberrant expression of microRNA (miRNA) in tissues may lead to altered level in circulation. Considerable evidence has suggested that miRNA deregulation is involved in the pathogenesis of Parkinson's disease (PD). In this study, we screened a set of PD-associated miRNAs and aimed to identify differentially expressed miRNAs in plasma of PD patients and to evaluate their potentiality to serve as PD biomarkers. A total of 95 subjects consisting of 46 sporadic PD cases and 49 controls were recruited. Plasma levels of six miRNAs including miR-433, miR-133b, miR-34b, miR-34c, miR-153, and miR-7 were evaluated using reverse transcribed quantitative PCR, among which we found that miR-34c and miR-7 were below detection limit under our condition...

Curcumin is known as a natural dietary polyphenol which is extracted from Curcuma longa L. It has been shown that curcumin has a variety of pharmacological effects such as antioxidant, anti-cancer, anti-inflammatory, and anti-microbial activities. Anti-cancer effects of curcumin are due to targeting of a wide range of cellular and molecular pathways involved in cancer pathogenesis including NF-kB, MAPK, PTEN, P53, and microRNAs (miRNA) network. Multiple lines of evidence have indicated that curcumin exerts its therapeutic effects via regulating miRNA expression (e...

Of the thousands of long noncoding RNAs expressed in embryonic stem cells (ESCs), few have known roles and fewer have been functionally implicated in the regulation of self-renewal and pluripotency, or the reprogramming of somatic cells to the pluripotent state. In ESCs, Cyrano is a stably expressed long intergenic noncoding RNA with no previously assigned role. We demonstrate that Cyrano contributes to ESC maintenance, as its depletion results in the loss of hallmarks of self-renewal. Delineation of Cyrano's network through transcriptomics revealed widespread effects on signaling pathways and gene expression networks that contribute to ESC maintenance...

It was reported that puerarin decreases the total cholesterol, low-density lipoprotein cholesterol (LDL-C), triglyceride (TG) and increases high-density lipoprotein cholesterol (HDL-C) level, but the underlying mechanism is unclear. This study was designed to determine whether puerarin decreased lipid accumulation via up-regulation of ABCA1-mediated cholesterol efflux in THP-1 macrophage-derived foam cells. Our results showed that puerarin significantly promoted the expression of ATP-binding cassette transporter A1 (ABCA1) mRNA and protein via the AMP-activated protein kinase (AMPK)-peroxisome proliferator-activated receptor gamma (PPARγ)-liver X receptor-alpha (LXR-α) pathway and decreased cellular lipid accumulation in human THP-1 macrophage-derived foam cells...
