Stammzellen sind an der Bildung und Entwicklung vieler Gewebe und spezialisierter Zelltypen eines Organismus beteiligt. Dabei ist die Ausbildung der Zelltypen eines menschlichen Organismus nicht auf die fruhe Embryonalentwicklung beschrankt. Auch im

Although a pathway that requires sequential activation of Ras, Raf, and MAP kinase kinase has been proposed as the major mechanism for stimulation of mitogen-activated protein kinase (MAP kinase), alternative pathways also exist. A wide variety of ex

The c-Raf-1 serine/threonine kinase is an important component of signal transduction pathways mediating the effects of a variety of growth factors. In activated T cells, IL-2 has been shown to induce activation of c-Raf-1, but c-Raf-1 has not previou

v-Src activates promoters under the control of 12-O-tetradecanoylphorbol-13-acetate (TPA) response elements (TREs) and serum response elements (SREs) via two distinguishable intracellular signaling mechanisms. The induction of TRE- and SRE-mediated g

B-Raf, a member of the Raf family of serine/threonine kinases, is expressed primarily in the brain and in the nervous system. In this study, the biochemical properties of the B-Raf protein were investigated in nerve growth factor (NGF)-responsive cel

In resting cells, c-Jun is phosphorylated on five sites. Three of these sites reside next to its DNA binding domain and negatively regulate DNA binding. In response to expression of oncogenic Ha-Ras, phosphorylation of these sites decreases, while ph

The protein-tyrosine kinase activity of v-Src leads to the transcriptional activation of the mitogen-responsive transcription factor Egr-1. c-Raf-1 is a serine/threonine protein kinase that has been implicated in the transduction of signals induced b

Sinusoidal Ito cells (stellate or fat-storing cells) undergo excessive cellular proliferation before the establishment and progression of hepatic fibrosis and cirrhosis. Retinoic acid and transforming growth factor beta (TGF beta) both inhibit Ito-ce

Erythropoietin mediates the rapid phosphorylation of Raf-1 in the murine cell lines HCD-57 and FDC-P1/ER, which proliferate in response to this cytokine. Phosphorylation occurs at both serine and tyrosine residues and as such is similar to the Raf-1
