Figure 4. Expression and diagnostic value of characterized genes. (A) The box plots showed the expression of three GC characteristic genes (BANF1, ADH7, TMEM27) in GSE54129-GSE118916 dataset. (B) ROC curves were used to evaluate the diagnostic efficacy of three GC characteristic genes (BANF1, ADH7, TMEM27) in GSE54129-GSE118916 dataset. (C) The box plots showed the expression of three GC characteristic genes (BANF1, ADH7, TMEM27) in GSE65801 dataset. (D) ROC curves were used to evaluate the diagnostic efficacy of three GC characteristic genes (BANF1, ADH7, TMEM27) in GSE65801 dataset. (E) The box plots showed the expression of three GC characteristic genes (BANF1, ADH7, TMEM27) in TCGA dataset. (F) ROC curves were used to evaluate the diagnostic efficacy of three GC characteristic genes (BANF1, ADH7, TMEM27) in TCGA dataset. *p < 0.05, ***p < 0.001.
