Regulation of Bcl-2 proteins during anoikis and amorphosis

Biochimica Et Biophysica Acta

Abstract

Adhesion to extracellular matrix regulates cell survival through both integrin engagement and appropriate cell spreading. Numerous signaling pathways converge to affect the levels and posttranslational modifications of Bcl-2 family proteins. Recent work has defined specific roles for different Bcl-2 proteins in the disruption of mitochondrial function that leads to cell death. Using this understanding of Bcl-2 protein function as a framework, we will consider the molecular mechanisms of apoptosis induced by integrin detachment (anoikis) and cell death stimulated by the loss of cytoskeletal architecture (amorphosis).

Breast Invasive Carcinoma

Invasive breast cancers indicate a spread into breast tissues and lymph nodes. Here are the latest discoveries pertaining to breast invasive carcinomas.

BCL-2 Family Proteins

BLC-2 family proteins are a group that share the same homologous BH domain. They play many different roles including pro-survival signals, mitochondria-mediated apoptosis and removal or damaged cells. They are often regulated by phosphorylation, affecting their catalytic activity. Here is the latest research on BCL-2 family proteins.

AKT Pathway

This feed focuses on the AKT serine/threonine kinase, which is an important signaling pathway involved in processes such as glucose metabolism and cell survival.

Adhesion Molecules in Health and Disease

Cell adhesion molecules are a subset of cell adhesion proteins located on the cell surface involved in binding with other cells or with the extracellular matrix in the process called cell adhesion. In essence, cell adhesion molecules help cells stick to each other and to their surroundings. Cell adhesion is a crucial component in maintaining tissue structure and function. Discover the latest research on adhesion molecule and their role in health and disease here.

Apoptotic Caspases

Apoptotic caspases belong to the protease enzyme family and are known to play an essential role in inflammation and programmed cell death. Here is the latest research.

Breast Invasive Carcinoma (Keystone)

Invasive breast cancers indicate a spread into breast tissues and lymph nodes. Here are the latest discoveries pertaining to breast invasive carcinomas.

Apoptosis in Cancer

Apoptosis is an important mechanism in cancer. By evading apoptosis, tumors can continue to grow without regulation and metastasize systemically. Many therapies are evaluating the use of pro-apoptotic activation to eliminate cancer growth. Here is the latest research on apoptosis in cancer.

Apoptosis

Apoptosis is a specific process that leads to programmed cell death through the activation of an evolutionary conserved intracellular pathway leading to pathognomic cellular changes distinct from cellular necrosis
