The expression of MEG3 in GC tissues and cell lines. a The expression of level of MEG3 was detected in 50 GC patients by RT-qPCR. Data was presented as fold change of GC tissues relative to adjacent normal regions; b Relative MEG3 expression level in GC tissues and adjacent normal regions; c The Statistical analysis of the association between MEG3 level and pM stage (No metastasis and Metastasis); d The Statistical analysis of the association between MEG3 level and pTNM stage (I, II, III and IV); e The relative level of MEG3 in GC cell lines (HGC-27,MGC-803, MKN-45, SGC-7901, BGC-823 and AGS) relative to 8 normal control samples; For all quantitative results, the data are presented as the mean ± SEM, and the error bars represent the standard deviation obtained from three independent experiments. *p < 0.05; **p < 0.01
