Abstract

The therapeutic effect and mechanism of total flavonoids in Isodon amethystoides (Ben-th) Cy Wu et Hsuan (TFIA) on adjuvant arthritis (AA) were investigated. AA model rats were set and complete Freund's adjuvant injection,randomly divided into 4 groups: AA group,AA+TFIA 50 mg/kg group,AA+TFIA 100 mg/kg group,AA+TFIA 150 mg/kg group,and each group has 10 rats. Blank control group was set without modeling (n=10). Four days post-modeling rats in each TFIA groups were treated once a day with TFIA at 50 mg/kg,100 mg/kg and 150 mg/kg for 24 d,and rats in blank control and AA groups were given saline as control. At the 12th day,16th day,20th day and 24th day of treatment,the effect of TFIA on AA rats was evaluated by rat arthritis score. Then the rats were sacrificed on the 24th day of treatment,and the synovial tissue of rats was isolated and the fibroblast-like synoviocytes (FLS) were primary cultured. The expressions of IL-1 in FLS was detected by ELISA,the FLS proliferation activity was detected by MTT assay,and the expression of miR-152,β-catenin and cyclin D1 gene (ccnd1) were detected by real time qPCR. MiR-152 mimics and NC mimics (control) were transfected into FLS in AA rats,and miR-152 inhibitors and NC inhibitors (control)...Continue Reading

Adherens Junctions

An adherens junction is defined as a cell junction whose cytoplasmic face is linked to the actin cytoskeleton. They can appear as bands encircling the cell (zonula adherens) or as spots of attachment to the extracellular matrix (adhesion plaques). Adherens junctions uniquely disassemble in uterine epithelial cells to allow the blastocyst to penetrate between epithelial cells. Discover the latest research on adherens junctions here.

Cadherins and Catenins

Cadherins (named for "calcium-dependent adhesion") are a type of cell adhesion molecule (CAM) that is important in the formation of adherens junctions to bind cells with each other. Catenins are a family of proteins found in complexes with cadherin cell adhesion molecules of animal cells: alpha-catenin can bind to β-catenin and can also bind actin. β-catenin binds the cytoplasmic domain of some cadherins.
