Epidermal growth factor activates nuclear factor-kappaB in human proximal tubule cells.

@article{citeulike:2261040, abstract = {The promotion of cell survival and regeneration in acute renal failure (ARF) is important for the restitution of renal function. Epidermal growth factor (EGF) has been implicated in the regulation of cell proliferation. We provide evidence for a direct link between EGF, nuclear factor-kappaB (NF-kappaB), and cell cycle regulation (cyclin D1). EGF was found to stimulate NF-kappaB-dependent gene transcription and DNA binding. In addition, EGF stimulated cyclin D1 promoter activity as well as cyclin D1 expression. Moreover, inhibition of NF-kappaB caused a pronounced reduction of EGF-induced cyclin D1 promoter activity. Furthermore, both EGF-mediated NF-kappaB activation and cyclin D1 expression were inhibited by coexpression of super IkappaB. Taken together, these data identify NF-kappaB and cyclin D1 as downstream targets of EGF and establish a molecular link between stimulation of EGF via activation of NF-kappaB and cyclin D1 expression in human proximal tubular cells.}, address = {Nephrology Div., Internal Medicine II, Univ. of Ulm, Robert-Koch-Strasse 8, D-89081 Ulm, Germany. ulla.haeussler@medizin.uni-ulm.de}, author = {H\"{a}ussler, U. and von Wichert, G. and Schmid, R.
