Figure 7. Relationship between immune cell markers and APOE transcription in GC. (A) Levels of ITGAX (P < 0.0001), NRP1 (P < 0.0001), ITGAM (P < 0.0001), CCR7 (P < 0.0001), CD8A (P < 0.0001) and CD8B (P < 0.0001) were significantly higher in APOE higher group. (B) Levels of ITGAX (r = 0.6098, P < 0.0001), NRP1 (r = 0.3538, P < 0.0001), ITGAM (r = 0.5375, P < 0.0001), CCR7 (r = 0.3775, P < 0.0001), CD8A (r = 0.5568, P < 0.0001) and CD8B (r = 0.457, P < 0.0001) are positively correlated with APOE expression in GC.
