Cell junction proteins play a pivotal role in regulating key physiological processes, including proliferation and apoptosis. E-cadherin, a crucial component of adherens junctions, is essential for maintaining intestinal epithelial homeostasis by modulating cell adhesion and proliferation. In this study, we explored the function of E-cadherin in the intestinal epithelial cells. Our findings indicate that during colitis, E-cadherin remains associated with the cell membrane in colonocytes. Furthermore, using an in vitro system, we demonstrated that in colonocytes, E-cadherin inhibits cell proliferation and β-catenin signaling while simultaneously activating the PI3K/Akt pathway. These results suggest that E-cadherin may suppress cell proliferation while promoting PI3K/Akt signaling in colonocytes of colitic mice.
期刊介绍：
The journal publishes original research articles and reviews on all aspects of cellular, molecular and structural biology, developmental biology, cell physiology and evolution. It will publish articles or reviews contributing to the understanding of the elementary biochemical and biophysical principles of live matter organization from the molecular, cellular and tissues scales and organisms.
This includes contributions directed towards understanding biochemical and biophysical mechanisms, structure-function relationships with respect to basic cell and tissue functions, development, development/evolution relationship, morphogenesis, stem cell biology, cell biology of disease, plant cell biology, as well as contributions directed toward understanding integrated processes at the organelles, cell and tissue levels. Contributions using approaches such as high resolution imaging, live imaging, quantitative cell biology and integrated biology; as well as those using innovative genetic and epigenetic technologies, ex-vivo tissue engineering, cellular, tissue and integrated functional analysis, and quantitative biology and modeling to demonstrate original biological principles are encouraged.
