Differential expression of ALDH isoforms in five cancer types. (a) ALDH1A2; (b) ALDH2; (c) ALDH3A2; (d) ALDH1B1; (e) ALDH1L2; (f) ALDH18A1; (g) ALDH1L1; (h) ALDH3B1; (i) ALDH3B2. Columns from left to right: BRCA case-control, BRCA pair, LUSC case-control, LUSC pair, LUAD case-control, LUAD pair, HNSC case-control, HNSC pair. ESSC case-control. Ratio was shown in Log₂ transformation. BRCA: breast cancer; LUSC: lung squamous cell carcinoma; LUAD: lung adenocarcinoma; HNSC: head and neck squamous cell carcinoma; ESSC: esophageal squamous cell carcinoma; case-control (all tumors vs. normal tissue); pair (pairwise tumor vs. normal tissue); *Only one pair of ESSC tumor vs. normal so there is only case-control comparison of ESSC data.
