Kaposi's sarcoma is a highly vascular tumor of lymphatic endothelial origin. Many deregulated miRNAs, including miR-126-3p, have been identified in Kaposi's sarcoma tissues. miR-126-3p is the most highly endothelial-specific miRNA that regulates vascular integrity and angiogenesis. In this study, we aimed to determine the effect of miR-126-3p on Kaposi's sarcoma cells through transfection of a ...

BACKGROUND MiR-126 is frequently downregulated in a variety of malignancies and acts as a potential tumor suppressor. It also played a tumor suppressor role in human melanoma through the direct or indirect repression of several key oncogenic molecules. METHODS qRT-PCR assay was performed to examine the expression of miR-126. Associations between miR-126 expression and various clinicopathologi...

MicroRNAs are a class of small RNAs that regulate the expression of target mRNAs by inhibiting translation or destabilizing target mRNAs. miR-126 is a microRNA that is highly enriched in endothelial cells. miR-126 has been found to promote angiogenesis and inhibit vascular inflammation in endothelial cells by repressing three target genes Sprouty-related EVH1 domain-containing protein 1 (SPRED1...

This study intends to explore the effects of microRNA-126 (miR-126) on cell proliferation, apoptosis, and tumor angiogenesis in hepatocellular carcinoma (HCC) by regulating epidermal growth factor-like domain 7 (EGFL7) through extracellular signal-regulated kinase (ERK) signaling. HCC tissues and adjacent normal tissues were obtained from 184 HCC patients. HCC cells were separately transfected ...

(b) An application for the export of classified technical data or other classified defense articles must be accompanied by seven copies of the data and a completed Form DSP–83 (see § 123.10 of thi...

UNLABELLED BACKGROUND miR-126 has been reported to be differentially expressed in various malignancies, whereas its role in the pathogenesis of tongue squamous cell carcinoma (TSCC) remains largely unknown. MATERIAL AND METHODS In this study, we collected 21 pairs of TSCC cancerous and adjacent non-cancerous tissue samples, with which we performed real-time PCR to determine and compare the expr...

Human cytochrome P450 (CYP)2A6 is responsible for the metabolic activation of tobacco-related nitrosamines, as well as the metabolism of nicotine and some pharmaceutical drugs. There are large interindividual differences in CYP2A6 activity and expression, largely attributed to genetic polymorphisms. However, the variability was observed within homozygotes of the wild-type CYP2A6 gene. In this s...

The introduction of miR profiling of chronic lymphocytic leukemia (CLL) patients with different cytogenetic profiles and responses to therapy has allowed incorporation of important miR-mRNA interactions into the understanding of disease biology. In this study, we performed miR expression analysis using NanoString nCounter to discover differentially regulated miRs after therapy with the Bruton t...

BACKGROUND This study was designed to examine whether transplantation of mesenchymal stem cells (MSCs) overexpressing miR-126 enhances angiogenesis in the infarcted myocardium of mice. METHODS MSCs were harvested from mice using density gradient centrifugation and adherent culture. MSCs were transfected with lentiviral vectors carrying mature miR-126. Mice models of myocardial infarction were...

Mouse prion protein PrP106-126 is a peptide corresponding to the residues 107-127 of human prion protein. It has been shown that PrP106-126 can reproduce the main neuropathological features of prionrelated transmissible spongiform encephalopathies and can form amyloid-like fibrils in vitro. The conformational characteristics of PrP106-126 fibril have been investigated by electron microscopy, CD...
