Circular RNAs (circRNAs) are related to rheumatoid arthritis (RA) development. However, the function and mechanism of circRNA pituitary tumor-transforming 1 interacting protein (circ- PTTG1IP) in RA unknown. The expression circ-PTTG1IP synovial tissues patients fibroblast-like synoviocytes from (RA-FLSs) were detected by RT-qPCR. results uncovered that was overexpressed RA-FLSs, knockdown suppr...
Toll-like receptor 4 (TLR4) is important in promoting the immune response in various cancers. Recently, TLR4 is highly expressed in a stage-dependent manner in gastric cancer, but the regulatory mechanism of TLR4 expression has been not elucidated it. Here, we investigated the mechanism underlying regulation of TLR4 expression through promoter methylation and histone modification between transc...
S-nitrosoglutathione (GSNO) is considered a natural nitric oxide (NO.) reservoir and a reactive nitrogen intermediate in animal cells, but little is known about this molecule and its metabolism in plant systems. In this work, using pea plants as a model system, the presence of GSNO in collenchyma cells was demonstrated by an immunohistochemical method. When pea plants were grown with a toxic Cd...
High glucose induces and activates Toll-like receptor 4 in endothelial cells of diabetic retinopathy
BACKGROUND Hyperglycemia-induced inflammation causes the dysfunction of blood vessels, and Toll-like receptor 4 (TLR4) plays a key role in inflammation-induced angiogenesis. However, the impact of TLR4 on the pathogenesis of diabetic retinopathy (DR) is poorly understood. In this study, we examined the expression of TLR4 in retinal vascular endothelial cells of patients with DR and diabetic mic...
asthma as a chronic inflammatory airway disease is considered to be the most common chronic disease that is involving genetic and environmental factors. toll like receptors (tlrs) and other inflammatory mediators are important in modulation of inflammation. in this study, we evaluated the role of tlr2 arg753gln and tlr4 asp299gly polymorphisms in the asthma susceptibility, progress, control lev...
I In this study, allelic polymorphism in candidate genes of TLR4 and IL2 involved in the immune system in four Iranian indigenous chickens were examined using PCR-RFLP technique. A total of 200 birds including common, West Azerbaijan, Marandi, Mazandarani indigenous chicken breeds were selected. For detection of mutation in TLR4 (257 bp) and IL2 (600 bp) genes the PCR products were digested b...
PURPOSE It was previously demonstrated that toll-like receptor 4 (TLR4) is involved in species-specific human retinal pigment epithelial (HRPE) photoreceptor outer segment recognition and oxidant production. This study was performed to demonstrate the classical role of TLR4 in HRPE endotoxin (lipopolysaccharide; LPS) binding leading to HRPE proinflammatory cytokine secretion. METHODS Cultured...
Recent findings unexpectedly revealed that human TLR4 can be directly activated by nickel ions. This activation is due to the coordination of nickel by a cluster of histidine residues on the ectodomain of human TLR4, which is absent in most other species. We aimed to elucidate the role of MD-2 in the molecular mechanism of TLR4/MD-2 activation by nickel, as nickel binding site on TLR4 is remote...
