Moreover, the high co-expressions of GBP5/ALDH1A1 (AHR = 2.63, CI = 1.11–6.19, p = 0.027, Table 4), GBP5/ALDH1A2 (AHR = 2.40, CI = 1.09–5.32, p = 0.03, Table 4), GBP5/CD166 (AHR = 2.30, CI = 1.07–4.92, p = 0.032, Table 4), and GBP5/ ABCG2 (AHR = 2.12, CI = 1.21–3.70, p = 0.008, Table 4) genes are found to be associated with OS in oral cancer patients from TCGA database. Here, ALDH1A2 is linked to lip and oral cavity carcinoma.
