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...

The advent of microRNA has potentially uncovered a new level of complexity to be considered for every biological process. Through the modulation of transcription and translation, microRNA alter the basal state of cells and the outcome of stimulatory events. The exact effect of the microRNA network and individual microRNA on cellular processes is only just starting to be dissected. In the immune...

Many observational studies have found that microRNA-196a2 rs11614913, microRNA-146a rs2910164, and microRNA-423 rs6505162 are associated with esophageal cancer risk. However, the results were mixed and inconsistent among these studies. We conducted a meta-analysis to assess the relationship between the polymorphisms of three microRNAs and esophageal cancer susceptibility. We systematically sear...

MicroRNAs are regulators of gene expression whose functions are critical for normal development and physiology. We have previously characterized mutations in a Caenorhabditis elegans microRNA-specific Argonaute ALG-1 (Argonaute-like gene) that are antimorphic [alg-1(anti)]. alg-1(anti) mutants have dramatically stronger microRNA-related phenotypes than animals with a complete loss of ALG-1. ALG...

Background Type 2 diabetes and periodontitis predispose to a higher risk of severe acute respiratory syndrome coronavirus (SARS-CoV-2) infection. Recent studies show upregulation innate immuno-regulatory microRNA-146a -155 in oral fluids patients with type as well periodontitis. The aim was investigate whether these microRNAs may relate patient susceptibility the infection via modulation SARS-C...
