ABSTRACT:
The present invention relates to a method for identifying cells having a predisposition to develop an intestinal phenotype, wherein the cells are characterized by the loss of expression of the RUNX3 gene and the expression of one or more intestinal marker genes. In particular, the invention is directed to the identification of cells, which exhibit an intestinal phenotype representing a precursor of gastric cancer. Furthermore, the invention discloses a method for identifying a compound inhibiting the development of an intestinal phenotype in cells having a predisposition to develop an intestinal phenotype. Finally, the invention also relates to kits of parts for performing these methods.
