Abstract

To investigate the influences of probiotics combined with sulfasalazine (SASP) on the expression of the Wnt/β-catenin signaling pathway in rats with ulcerative colitis (UC). A total of 60 clean level and healthy Sprague-Dawley (SD) rats were randomly divided into the normal group, model group, SASP group and combination therapy group, with 15 rats in each group. The rats in the normal group were given normal feeding, and those in the remaining three groups were subjected to the establishment of the UC model. During the modeling, the rats underwent daily gavage and were sacrificed after 4 weeks. Clinical symptoms and pathological changes in ulcer indexes and colon tissues were observed in each group. The expression levels of relative genes in the Wnt/β-catenin signaling pathway were detected by Polymerase Chain Reaction (PCR). Compared with those in the model group, the pathological sections of rats in the SASP group and combination therapy group showed significant improvement in the inflammatory response. The expression levels of relative genes in the Wnt/β-catenin signaling pathway were downregulated in rats of the SASP group and combination therapy group relative to those in the model group. SASP and probiotics alleviate UC b...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.
