The guanosine triphosphatases of the Rho and Rac subfamilies regulate protumorigenic pathways and are activated by guanine nucleotide exchange factors (Rho GEFs), which could be potential targets for anticancer therapies. We report that two Rho GEFs, Vav2 and Vav3, play synergistic roles in breast cancer by sustaining tumor growth, neoangiogenesis, and many(More)
The GTPase RhoA participates in a number of cellular processes, including cytoskeletal organization, mitogenesis and tumorigenesis. We have previously shown that the transforming activity of an oncogenic version of RhoA (Q63L mutant) was highly dependent on the transcriptional factor c-Myc. In contrast to these positive effects in the RhoA route, we show(More)
