Pasmant et al discovered that lncRNA ANRIL(CDKN2B antisense RNA1)is transcribed form the INK4b-ARF-INK4a gene cluster in the opposite direction [13]; Zhang et al. concluded that the over-expression of ANRIL had important function for the development of gastric carcinoma [14]. This evidence concerns the gene CDKN2B and gastric carcinoma.
