Our next objective was to decipher the functional states of cancer cells at the single-cell level, and CTNNB1 had a significant positive relationship with tumor angiogenesis (R = 0.36, p < 0.01, Figure 14A); CTNNB1 (R = −0.35, p < 0.01, Figure 14B), FOXO3 (R = −0.38, p < 0.001, Figure 14C), MAPK13 (R = −0.48, p < 0.01, Figure 14D), and RAB11A (R = −0.33, p < 0.0, Figure 14E) were shown to have a significant negative relationship with tumor invasion; and RAB11A and quiescence were positively correlated (R = 0.31, p = 0.01, Figure 14F). The gene discussed is FOXO3; the disease is cancer.
