Rheumatoid arthritis (RA) is a chronic autoimmune disease that causes inflammation and destruction of the joints as well as an increased risk of cardiovascular disease. RA synovial fibroblasts (RASFs) are involved in the progression of RA and release pro-inflammatory cytokines. On the other hand, microRNAs (miRs) may help control the inflammatory response of immune and non-immune cells. Therefo...

Interactions between gut microbes and anthropogenic pollutants have been under study. The authors investigated the effects of larval exposure to polychlorinated biphenyl 126 (PCB-126) on the gut microbial communities of tadpoles and frogs. Frogs treated with PCBs exhibited increased species richness in the gut and harbored communities significantly enriched in Fusobacteria. These results sugges...

OBJECTIVE To assess whether microRNA-126 (miR-126) targets phosphatidylinositol 3-kinase regulatory subunit beta (PIK3R2) and to determine the potential roles of miR-126 in regulating proliferation and invasion via the PIK3R2-mediated phosphatidylinositol 3 kinase (PI3K)-protein kinase B (Akt) signaling pathway in the human bladder BLS cell line. MATERIALS AND METHODS A recombinant lentivirus...

Leukocyte adhesion to brain endothelial cells, the blood-brain barrier main component, is a critical step in the pathogenesis of neuroinflammatory diseases such as multiple sclerosis (MS). Leukocyte adhesion is mediated mainly by selectins, cell adhesion molecules and chemokines induced by pro-inflammatory cytokines such as TNFα and IFNγ, but the regulation of this process is not fully clear. T...

Virus-induced cytoplasmic inclusion bodies (referred to as virus replication complexes [VRCs]) consisting of virus and host components are observed in plant cells infected with tobacco mosaic virus, but the components that modulate their form and function are not fully understood. Here, we show that the tobacco mosaic virus 126-kD protein fused with green fluorescent protein formed cytoplasmic ...

miR-126 has recently been implicated in modulating angiogenic factors in vascular development. Understandings its biological significance might enable development of therapeutic interventions for diseases like age-related macular degeneration (AMD). We aimed to determine the role of miR-126 in AMD using a laser-induced choroidal neovascularization (CNV) mouse model. CNV was induced by laser pho...

Osteosarcoma (OS) is the most common malignant bone tumor in children and young adults, the early symptoms and signs of which are non-specific. The discovery of microRNAs (miRNAs) provides a new avenue for the early diagnosis and treatment of OS. miR-126 has been reported to be highly expressed in vascularized tissues, and is recently widely studied in cancers. Herein, we explored the expressio...

RATIONALE Endothelial microRNA-126 (miR-126) modulates vascular development and angiogenesis. However, its role in the regulation of smooth muscle cell (SMC) function is unknown. OBJECTIVE To elucidate the role of miR-126 secreted by endothelial cells (ECs) in regulating SMC turnover in vitro and in vivo, as well as the effects of shear stress on the regulation. METHODS AND RESULTS Cocultur...

BACKGROUND The aim of this study was to investigate the potential function of miR-126 in neural stem cells (NSCs). MATERIAL AND METHODS Expression level of miR-126 was detected by quantitative real-time PCR (qRT-PCR). MiR-126 overexpression was established by transfecting miR-126 mimics into human NSC lines (HB1.F3 and HB1.A4 cells). Its effects on cell proliferation were studied using cell-c...

MicroRNA-126 (miR-126) has been found to promote angiogenesis, but the underlying mechanisms are still unclear. So, we conducted this study to explore the effect of miR-126 expression on angiogenesis in hepatocellular carcinoma (HCC) after transcatheter arterial chemoembolization (TACE). The expression levels of miR-126 and sprouty-related, EVH1 domain containing protein (Spred)1 in surgically ...
