The loss-of-function of DNA methyltransferase 1 by siRNA impairs the growth of non-small cell lung cancer with alleviated side effects via reactivation of RASSF1A and APC <i>in vitro</i> and <i>vivo</i>.
In this study we set out to test the hypothesis that loss of Rassf1a can cooperate with inactivation of the adenomatous polyposis coli (Apc) gene to accelerate intestinal tumourigenesis using the Apc-Min (Apc(Min/+)) mouse model, as mutational or deletional inactivation of APC is a frequent early event in the genesis of intestinal cancer.
