Furthermore, a significant correlation between RASSF1A methylation and impaired lung cancer patient survival was reported, and RASSF1A silencing was correlated with several parameters of poor prognosis and advanced tumor stage (e.g. poor differentiation, aggressiveness, and invasion).

We examined 514 cases of NSCLC and 84 corresponding nonmalignant lung tissues from 4 countries (USA, Australia, Japan and Taiwan) for the methylation status of 7 genes known to be frequently methylated in lung cancers [p16, RASSF1A (RAS association domain family 1), APC, RARbeta, CDH13, MGMT and GSTP1].

Recently, the RASSF1A gene was isolated from the 3p21.3 region homozygously deleted in lung and breast cancer cell lines, and it was shown to be inactivated by hypermethylation of the promoter region in lung cancers.

We also transfected a lung cancer cell line that lacks RASSF1A expression with vectors containing RASSF1A complementary DNA to determine whether exogenous expression of RASSF1A would affect in vitro growth and in vivo tumorigenicity of this cell line.All statistical tests were two-sided.
