Signal transduction in mesangial cells.
Phenotype, growth, and functional characteristics of glomerular mesangial "myofibroblasts" are under the control of multiple hormones, vasoactive agents, autacoids, and cytokines. Several parallel signal transduction pathways couple receptor occupancy with functional changes, including phospholipases C, A2, and D breakdown of membrane phospholipids, and adenylate/guanylate cyclase activation. C...
متن کاملSignal transduction in T cells.
Rapid progress was made during the past year in the delineation of the nature of the initial biochemical events triggered by the T-cell antigen receptor. Antigen-mediated activation of phospholipase C was demonstrated to require protein tyrosine phosphorylation and, most surprising, activation of the Ras family of signal transduction molecules was shown to closely follow stimulation of the T-ce...
متن کاملThe epidermal growth factor-induced calcium signal in A431 cells.
Addition of epidermal growth factor (EGF) to human A431 cells causes a 2-4-fold increase in cytoplasmic free Ca2+ concentration ([Ca2+]i) as measured by quin-2 fluorescence. The EGF effect is rapid but transient: [Ca2+]i reaches a maximum within 30-60 s and then returns to its resting value (182 +/- 3 nM) over a 5-8-min period. The EGF-induced [Ca2+]i rise is completely dependent on extracellul...
متن کاملexpression of pml tumor suppressor in a431 cells reduces cellular growth by inhibiting the egfr expression
our previous studies showed that the promyelocytic leukemia protein, pml, functions as acellular and growth suppressor. transient expression of pml was also found to repress the activity of theepidermal growth factor receptor (egfr) gene promoter. in this study, we have examined the effects ofpml on a431 cells, which express a high level of egfr protein. the pml gene was introduced into thecell...
متن کاملVaccinia virus regulates expression of p21WAF1/Cip1 in A431 cells.
In this paper, we provide evidence that both the mRNA and protein levels of the cyclin-dependent kinase (CDK) inhibitor p21WAF1/CDK-interacting protein 1 (Cip1) increase upon infection of A431 cells with Vaccinia virus (VACV). In addition, the VACV growth factor (VGF) seems to be required for the gene expression because infection carried out with the mutant virus VACV-VGF- revealed that this st...
