miR-122-5p as a novel biomarker for alpha-fetoprotein-producing gastric cancer

Figure 2 Quantification of miR-122-5p expression levels by quantitative reverse transcription-polymerase chain reaction. A: Comparison of miR-122-5p expression levels between normal gastric mucosa, non-alpha-fetoprotein-producing gastric cancer (AFPGC) and AFPGC in tissue samples. ^aP < 0.05, compared to normal gastric mucosa; ^bP < 0.05, compared to non-AFPGC; B: Comparison of miR-122-5p expression levels between health volunteers, non-AFPGC and AFPGC in plasma sample. ^aP < 0.05, compared to health volunteers; ^bP < 0.05, compared to non-AFPGC. The lines inside the bow plot represent the average size.
