WebAug 15, 2006 · In addition, the phosphorylation of ERK1/2, downstream effectors of FIP1L1-PDGFRα signaling, were also reduced upon treatment with sorafenib. Taken together, these results confirmed that sorafenib is a potent inhibitor of both FIP1L1-PDGFRα and FIP1L1-PDGFRα(T674I) . In contrast, a direct inhibitory effect of K-252a on these kinases could ... WebMay 23, 2006 · In this report, we demonstrate that FIP1L1 is completely dispensable for PDGFRα activation in vitro and in vivo. Instead, truncation of PDGFRα between two conserved tryptophan residues in the …
