We previously found that deficiency in the mouse Gab1 gene led to embryonic lethality and defects in ERK activation in response to growth factors and cytokines. Here, we established immortalized Gab1-/-cell lines and analysed roles of Gab1 in growth factor-mediated signaling and oncogenesis. EGF-dependent activation of c-Raf and Mek1/2, which function upstream of ERKs, was perturbed in Gab1-/-cells. EGF-mediated upregulation of GTP-bound form of Ras was also reduced in these cells. EGF-dependent GTP/GDP exchange activity for Ras was suppressed in the Gab1-/-cells and expression of a constitutively active Sos restored ERK activation in these cells, indicating that Gab1 functions upstream of Ras. Furthermore, activated form of ErbB2 (active ErbB2)-mediated transformation, such as colony formation in soft agar and tumor formation in nude mice, was strongly suppressed when the Gab1-/-cells were transfected with active ErbB2, whereas the active Sos efficiently induced transformation of Gab1-/-cells. The data show that Gab1 plays an essential role in EGF-receptor/ErbB-mediated cell proliferation and oncogenesis."xsd:string |
