Research Abstract

The human runt-related gene RUNX3, located on chromosome 1p36, is a major mediator of signals elicited by members of the transforming growth factor-β (TGF-β) superfamily. Here we show that 45-60% of gastric cancer cell lines and surgically resected specimens do not significantly express RUNX3 due to a combination of hemizygous deletion and hypermethylation of the RUNX3 promoter region. Tumorigenicity of gastric cancer cell lines in nude mice was inversely related to their level of AML2(RUNX3) expression, and one gastric tumor associated mutation (R122C), occurring within the conserved Runt domain completely abolished the tumor suppressive effect of RUNX3. The results suggest that a lack of RUNX3 function is causally related to the genesis and progression of human gastric cancer.
