MicroRNAs play important roles in controlling the embryonic stem cell (ESC) state. Although much is known about microRNAs maintaining ESC state, microRNAs that are responsible for promoting ESC differentiation are less reported. Here, by screening 40 microRNAs pre-selected by their expression patterns and predicted targets in Dgcr8-null ESCs, we identify 14 novel differentiation-associated micr...

Psoriasis is a chronic, autoimmune, and complex genetic disorder that affects 23% of the European population. The symptoms of Psoriatic skin are inflammation, raised and scaly lesions. microRNA, which is short, nonprotein-coding, regulatory RNAs, plays critical roles in psoriasis. microRNA participates in nearly all biological processes, such as cell differentiation, development and metabolism....

Abstract Time spent sitting is positively correlated with endothelial dysfunction and cardiovascular disease risk. The underlying molecular mechanisms are unknown. MicroRNAs contained in extracellular vesicles (EVs) reflect cell/tissue status mediate intercellular communication. We explored the association between patterns microRNAs isolated from cell (EC)-derived EVs. Using extant actigraphy b...

Purpose: The prognosis of head and neck squamous cell carcinomas (HNSCC) remains disappointing and the development of novel anti-cancer agents is urgently awaited. We identified by a functional genetic screen microRNAs that are selectively lethal for head and neck cancer cells but not for normal cells. We further investigated the genes targeted by these microRNAs. Experimental Design: A retrovi...

After the milestone discovery of the first microRNA in 1993, the past five years have seen a phenomenal surge of interest in these short, regulatory RNAs. Given that 2% of all known human genes encode microRNAs, one main goal is to uncover microRNA function. Although it has been more difficult to assign function to microRNAs in animals than it has been in plants, important roles are emerging: i...

PURPOSE microRNAs have been shown to be involved in different human cancers. We therefore have performed expression profiles on a panel of pediatric tumors to identify cancer-specific microRNAs. We also investigated if microRNAs are coregulated with their host gene. EXPERIMENTAL DESIGN We performed parallel microRNAs and mRNA expression profiling on 57 tumor xenografts and cell lines represen...

MicroRNAs are small, noncoding RNA molecules that regulate gene expression at the post-transcriptional level and play an important role in various biological processes. Although most microRNAs expression profiles studies have been performed in humans or rodents, relatively limited knowledge also exists in other mammalian species. The identification of the full repertoire of microRNAs expressed ...

The mechanisms of action extracellular miRNAs are given in the scientific review. To write article, information was searched using Scopus, Web Science, MedLine, PubMed, Google Scholar, EMBASE, Global Health, Cochrane Library databases. authors state that generated by producer cells and then packaged vesicles delivered to other functionally active structures. Extracellular transport miRNA a para...

Pulmonary hypertension is a devastating and refractory disease and there is no cure for this disease. Recently, microRNAs and mesenchymal stem cells emerged as novel methods to treat pulmonary hypertension. More than 20 kinds of microRNAs may participate in the process of pulmonary hypertension. It seems microRNAs or mesenchymal stem cells can ameliorate some symptoms of pulmonary hypertension ...

MicroRNAs are small noncoding RNAs that function to control gene expression. These small RNAs have been shown to contribute to the control of cell growth, differentiation and apoptosis, important features related to cancer development and progression. In fact, recent studies have shown the utility of microRNAs as cancer-related biomarkers. This is due to the finding that microRNAs display alter...
