Objectives Single nucleotide polymorphisms in microRNAs (microRNA-196a2 rs11614913, microRNA-146a rs2910164, microRNA-149 rs2292832 and microRNA-499 rs3746444) have been inconsistently associated with risk for oral squamous cell cancer (OSCC). This meta-analysis aimed to assess the correlation between microRNA polymorphisms and susceptibility to OSCC. Materials and Methods Free words were use...

Many of the known microRNAs are encoded in polycistronic transcripts. Here, we reconstruct the evolutionary history of the mir17 microRNA clusters which consist of miR-17, miR-18, miR-19a, miR-19b, miR-20, miR-25, miR-92, miR-93, miR-106a, and miR-106b. The history of this cluster is governed by an initial phase of local (tandem) duplications, a series of duplications of entire clusters and sub...

BACKGROUND It is controversial whether microRNA-126 is a tumor suppressive or oncogenic miRNA. More experiments are needed to determine whether microRNA-126 is associated with non-small cell lung cancer risk and prognosis. METHODS Over-expression of microRNA-126 was performed to evaluate the cell invasion and tumor growth in non-small cell lung cancer (NSCLC) cell lines and nude mouse xenogra...

To explore the effect of circular RNA_0025033 on proliferation, migration and invasion cervical cancer HeLa cells its molecular mechanism. The tissues adjacent 39 patients with in our hospital from January 2017 to December 2020 were selected. expression levels microRNA-1256 detected by Quantitative reverse transcription polymerase chain reaction. Cell counting kit 8 was used detect cell viabili...

To investigate the influence of harpagide isolated from Scrophularia ningpoensis Hemsl. on human umbilical vascular endothelial cells damage induced by oxidized low-density lipoprotein and its possible mechanism. Human were cultured in vitro. Different doses (20, 40, 80 μmol/l) applied to treat lipoprotein, overexpressing microRNA-140-5p μg/ml was with downregulation. Enzyme-linked immunosorben...

Mammalian hibernation involves re-programming of metabolic functions, in part, facilitated by microRNA. Although much is known about microRNA function, we lack knowledge on low temperature microRNA target selection. It is possible that the thermodynamics of microRNA target selection could dictate unique temperature-dependent sets of microRNA targets for hibernators.

MicroRNAs 21 and 145 exhibit inverse expression in Hepatocellular carcinoma (HCC), but how they relate to Smad3 C-terminal and Link region phosphorylation (pSmad3C and pSmad3L) downstream of TGF-β/MAPK signaling, remains inconclusive. Our results suggest microRNA-145 targets Smad3 in HepG2 cells. Decreased tumor volume and increased apoptosis were produced in both microRNA-21 antagomir and micr...
