AMP-activated protein kinase/myocardin-related transcription factor-A signaling regulates fibroblast activation and renal fibrosis.
Chronic kidney disease is a major cause of death, and renal fibrosis is a common pathway leading to the progression of this disease. Although activated fibroblasts are responsible for the production of the extracellular matrix and the development of renal fibrosis, the molecular mechanisms underlying fibroblast activation are not fully defined. Here we examined the functional role of AMP-activa...
متن کاملBasic Fibroblast Growth Factor Confers Growth Inhibition and Mitogen-activated Protein Kinase Activation in Human Breast Cancer Cells1
The effect of basic fibroblast growth factor (bFGF) on human breast cancer cells was studied in vitro. Exposure to bFGF resulted in significant growth inhibition, decreased DNA synthesis, and accumulation of cells in G0-G1. The IC50 for growth inhibition in MCF-7 cells was 50 pglml, and it was abrogated by neutralizing antibodies against bFGF. Inhibition of growth by bFGF was predominant over t...

متن کاملRas- and Mitogen-activated Protein Kinase Kinase-dependent and -independent Pathways in p21 Induction by Fibroblast Growth Factor-2, Platelet-derived Growth Factor, and Transforming Growth Factor-b1
p21 (hereafter referred to as p21) is upregulated in differentiating and DNA-damaged cells, but it is also up-regulated by serum and growth factors. We show here that fibroblast growth factor-2 (FGF-2), platelet-derived growth factor (PDGF), and transforming growth factor-b1 (TGF-b1) all induce p21 expression in mouse fibroblasts, but with markedly different kinetics. We link their effect on p2...
متن کاملHuman mitogen-activated protein kinase kinase kinase mediates the stress-induced activation of mitogen-activated protein kinase cascades.
The mitogen-activated protein kinase (MAPK) cascades represent one of the important signalling mechanisms in response to environmental stimuli. We report the identification of a human MAPK kinase kinase, MAPKKK4, via sequence similarity with other MAPKKKs. When truncated MAPKKK4 (DeltaMAPKKK4) was overexpressed in HEK293 cells, it was constitutively active and induced the activation of endogeno...
