Neu Differentiation Factor Inhibits EGF Binding

Human cytomegalovirus infection inhibits epidermal growth factor (EGF) signalling by targeting EGF receptors.

Infection with human cytomegalovirus (HCMV) is known to involve complex interactions between viral and cellular factors resulting in perturbation of a number of cellular functions. Specifically, HCMV infection targets control of the cell cycle, cellular transcription and immunoregulation, presumably to optimize the cellular environment for virus persistence and productive infection. Here, we sh...

Fetal Thymocyte Growth and Differentiation: Epidermal Growth Factor (EGF) Modulates

Heparin-dependent binding and autophosphorylation of epidermal growth factor (EGF) receptor by heparin-binding EGF-like growth factor but not by EGF.

Heparin-binding EGF-like growth factor (HB-EGF) is a recently identified member of the EGF family of growth factors and a potent mitogen for smooth muscle cells and fibroblasts. Chinese hamster ovary (CHO) cells genetically engineered to express the human EGF receptor bind with high affinity both EGF and HB-EGF. CHO mutant cells lacking heparan sulfate proteoglycans (HSPG) bind EGF equally well...

Connective tissue growth factor inhibits adipocyte differentiation.

Adipocyte differentiation is a key process implicated in the pathogenesis of obesity and insulin resistance. Its regulation is triggered by a cascade of transcription factors, including the CCAAT/enhancer binding proteins (C/EBPs) and peroxisome proliferator-activated receptor-gamma (PPARgamma). Growth factors such as transforming growth factor-beta1 (TGF-beta1) are known to inhibit adipocyte d...

Structure and function of heparin-binding EGF-like growth factor (HB-EGF).

Heparin-binding EGF-like growth factor (HB-EGF) is a 22 kDa, O-glycosylated protein that is mitogenic for fibroblasts, smooth muscle cells (SMC) and epithelial cells. This review describes the primary structure of HB-EGF, as well as its processing. The structure of the mouse and human HB-EGF genes is also discussed. Finally, this review summarizes HB-EGF expression patterns, receptor-mediated s...
