Figure 5. The link between the ALDH6A1 expression and immune regulation of GC. (A) The picture has conveyed the correlation between the expression level of ALDH6A1 and 24 types of immune cells. (B) The TISIDB platform portraying the link between ALDH6A1 and CD56dim cells, Treg (p < 0.05). (C, D) Both the heatmap and the scatterplot have illustrated that the ALDH6A1 expression was positively related to VSIR (p < 0.05).
