Huangqin Qingre Chubi Capsule improves rheumatoid arthritis accompanied depression through the Wnt1/β-catenin signaling pathway.

Aim Of The Study: Research on the mechanism of Huangqin Qingre Chubi Capsules (HQC) in improving rheumatoid arthritis accompanied depression (RA-dep) model rats.

Methods: We employed real-time qPCR (RT-qPCR), western blotting (WB), confocal microscopy, bioinformatics, and other methods to investigate the anti-RA-dep effects of HQC and its underlying mechanisms.

Results: HQC alleviated the pathological indexes of inflammation and depression in RA-dep model rats, decreased the levels of tumor necrosis factor (TNF)-α, interleukin (IL)-1β and IL-6, increased the levels of norepinephrine(NE) and serotonin(5-HT), and improved the injury of hippocampus.

Circ_0011058 alleviates RA pathology through the circ_0011058/miR-335-5p/CUL4B signal axis.

Our previous study found that Cullin 4B (CUL4B) inhibited rheumatoid arthritis (RA) pathology through glycogen synthase kinase-3beta (GSK3β)/canonical Wnt signalling pathway. In this work, pre-experiment and bioinformatics analysis suggested that circ_0011058 may lead to the up-regulation of CUL4B expression by inhibiting miR-335-5p. Therefore, we studied whether circ_0011058 can promote the expression of CUL4B through sponging the miR-335-5p and further promote the pathological development of RA.

Dysregulation of circRNAs in rheumatoid arthritis, with special emphasis on circRNAs secreted by exosomes and the crosstalk between circRNAs and RNA methylations.

Background: Rheumatoid arthritis (RA) is an autoimmune disease caused by a variety of unknown factors. It mainly occurs in the small joints of hands and feet, leading to cartilage destruction and bone erosion. Various pathologic mechanisms such as exosomes and RNA methylations are involved in the pathogenesis of RA.

RNA methylations in hepatic fibrosis, a gradually emerging new treatment strategy.

Background: Hepatic fibrosis (HF) is a pathological process caused by excessive accumulation of extracellular matrix caused by a series of causes, leading to the formation of fiber scar. RNA methylation is a newly discovered epigenetic modification that exists widely in eukaryotes and prokaryotes and plays a crucial role in the pathogenesis of many diseases.

Results: The occurrence and development of HF are regulated by many factors, including excessive deposition of extracellular matrix, activation of hepatic stellate cells, inflammation, and oxidative stress.

Progress in epigenetic regulation of milk synthesis, with particular emphasis on mRNA regulation and DNA methylation.

Inadequate milk secretion and a lack of nutrients in humans and mammals are serious problems. It is of great significance to clarify the mechanisms of milk synthesis and treatment methods. Epigenetic modification, represented by RNA methylation, is an important way of gene expression regulation that profoundly affects human gene expression and participates in various physiological and pathological mechanisms.

Sodium houttuyfonate in vitro inhibits biofilm dispersion and expression of bdlA in Pseudomonas aeruginosa.

Biofilm dispersion is the last step in the development of biofilms, and allows bacteria to spawn novel biofilms in new locales. In the previous studies, we found that sodium houttuyfonate (SH) is effective at inhibiting biofilm formation and motility of Pseudomonas aeruginosa. Here, we investigated the effect of SH against the biofilm dispersion of P.

Sodium houttuyfonate affects production of N-acyl homoserine lactone and quorum sensing-regulated genes expression in Pseudomonas aeruginosa.

Quorum sensing (QS) is a means of cell-to-cell communication that uses diffusible signaling molecules that are sensed by the population to determine population density, thus allowing co-ordinate gene regulation in response to population density. In Pseudomonas aeruginosa, production of the QS signaling molecule, N-acyl homoserine lactone (AHL), co-ordinates expression of key factors of pathogenesis, including biofilm formation and toxin secretion. It is predicted that the inhibition of AHL sensing would provide an effective clinical treatment to reduce the expression of virulence factors and increase the effectiveness of antimicrobial agents.
