In the present study, the Rho inhibitor affected cell attachment in one of the diffuse-type cancers, such as SC-6-JCK (poorly differentiated adenocarcinoma), while the other two diffuse-type cancers, MKN45 (poorly differentiated adenocarcinoma) and SH-10-TC (mucinous adenocarcinoma), were not affected. This evidence concerns the gene RHO and mucinous adenocarcinoma.
