MIR-155 AND MIR-221/222 ATTENUATE ANGIOTENSION II INDUCED ENDOTHELIAL INFLAMMATION BY TARGETING ETS-1

Mutator activity induced by microRNA-155 (miR-155) links inflammation and cancer.

Infection-driven inflammation has been implicated in the pathogenesis of ~15-20% of human tumors. Expression of microRNA-155 (miR-155) is elevated during innate immune response and autoimmune disorders as well as in various malignancies. However, the molecular mechanisms providing miR-155 with its oncogenic properties remain unclear. We examined the effects of miR-155 overexpression and proinfl...

miR-155 Is Essential for Inflammation-Induced Hippocampal Neurogenic Dysfunction.

Peripheral and CNS inflammation leads to aberrations in developmental and postnatal neurogenesis, yet little is known about the mechanism linking inflammation to neurogenic abnormalities. Specific miRs regulate peripheral and CNS inflammatory responses. miR-155 is the most significantly upregulated miR in primary murine microglia stimulated with lipopolysaccharide (LPS), a proinflammatory Toll-...

Targeting miR-155 to Treat Experimental Scleroderma

Scleroderma is a refractory autoimmune skin fibrotic disorder. Alterations of microRNAs in lesional skin could be a new approach to treating the disease. Here, we found that expression of miR-155 was up regulated in lesional skin tissue from patients with either systemic or localized scleroderma, and correlated with fibrosis area. Then we demonstrated the potential of miR-155 as a therapeutic t...

MiR-103 regulates the angiogenesis of ischemic stroke rats by targeting vascular endothelial growth factor (VEGF)

Objective(s): To investigate the effect of miR-103 on the angiogenesis of ischemic stroke rats via targeting vascular endothelial growth factor (VEGF) at the molecular level. Materials and Methods: Rat models had received the middle cerebral artery occlusion (MCAO) or sham operation before grouping, and cell models of oxygen-glucose deprivation (OGD) were performed. FITC-dextran, matrigel, and ...
