In addition, the data from GSE29623 including 65 COAD patients (p = 0.009, 38.72 months vs. NR, Figure 1C) and GSE71187 including 52 COAD cases (p = 0.015, 35.04 months vs. NR, Figure 1D) further displayed that high expression of ATP6V1C2 [expression ≥6.65 in GSE29623 (n = 16) and expression ≥1.24 in GSE71187 (n = 13)] predicted a poor OS in COAD. The gene discussed is ATP6V1C2; the disease is colon adenocarcinoma.
