In order to verify the result, RT-qPCR and western blot analysis were conducted for the measurement of expression patterns of Wnt2b, β-catenin, CyclinD1, N-cadherin, Vimentin, snail, LOC100505817 as well as E-cadherin in the harvested GC tumor tissues, to investigate the mechanism by which LOC100505817 and Wnt/β-catenin signaling pathway affects GC. This evidence concerns the gene CDH2 and gastric cancer.
