Abstract

Several distinct peptides or drugs that block the Rho family GTPases-mediated pathways were found to suppress RAS-induced malignant phenotype. They include (1) C3 enzyme that selectively inactivates Rho, (2) ACK42, a peptide that blocks the interaction of CDC42 with its effectors such as ACKs, (3) PAK18, a peptide that blocks the activation of PAK and membrane ruffling, and (4) actin-binding drugs, chaetoglobosin K (CK) and MKT-077, that block membrane ruffling by capping and bundling actin filaments, respectively.
