DLC1 and hepatocellular carcinoma: One ARHGAP, DLC1 (ARHGAP7), suppresses cell proliferation, anchorage-independent growth, and in vivo tumorigenicity of hepatocellular carcinoma by negatively regulating the activity of Rho proteins5.Conversely, by gaining fusion genes, ARHGAP6/ARHGAP26 fusions decrease cell apoptosis in gastric cancer6.
