WebJul 8, 2004 · Complete inhibition of the pathway was confirmed using a phospho-specific antibody to activated ERK in Western blots and by the observation that Raf was no longer able to induce p21 Cip1 in the presence of the inhibitor ( Figure 4Ai ). WebThe Ras/Raf/MEK/ERK and Ras/PI3K/PTEN/Akt pathways interact with each other to regulate growth and in some cases tumorigenesis. For example, in some cells, PTEN mutation may contribute to suppression of the Raf/MEK/ERK cascade due to the ability of activated Akt to phosphorylate and inactivate different Rafs.

WebFeb 1, 2001 · Thus, loss of p53 or p21 Cip1 function is necessary to disable growth-inhibitory Raf/MAP kinase signalling. Activation of oncogenes, including Ras, has been reported to stabilize and activate p53 via induction of the tumour suppressor p19 ARF. However, the response to Raf in p19 ARF−/− keratinocytes was indistinguishable from wild-type ...
