The aim of thepresent work is to use the GLAD-PCR assay to detect the aberrantly methylatedR(5mC)GY sites in the regulatory regions of tumor suppressor genes(brinp1, bves, cacna2d3,cdh11, cpeb1, epha7,fgf2, galr1, gata4,hopx, hs3st2, irx1,lrrc3b, pcdh10, rprm,runx3, sfrp2, sox17,tcf21, tfpi2, wnt5a,zfp82, and znf331) in DNA samples obtainedfrom gastric cancer (GC) tissues. Here, BRINP1 is linked to gastric cancer.
