Abstract

A systematic investigation of the chemopreventive effect of sulindac (SL) in combination with either epigallocatechin gallate (EGCG) or kaempferol similar (KMP) has been carried out 1,2-dimethyl hydrazine-treated rats (DMH). Those SL combinations with KMP and EGCG have enhanced the SL activity producing greater antioxidant, anti-inflammatory, antiproliferating, and apoptotic activities in both combinations than SL alone. The chemopreventive effects of SL with both EGCG and KMP were demonstrated by a decrease in thiobaribituric acid reactive substances level, tissue nitric oxide (NO), serum, and tissue β-catenin as well as a reduction in the multiplicity of aberrant crypt foci (ACF) with alleviation in the dysplastic changes that resulted from DMH administration. Down-regulation of proliferating cell nuclear antigen (PCNA) and cyclooxygenase-2 (COX-2) were also confirmed by immunohistochemical staining. The current study paves the way for the use of sulindac combination with kaempferol or EGCG as potential chemopreventive agents against colon cancer with more effect in combination with EGCG.

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.
