SLC43A2 and neoplasm: Figure 2 showed the expression differences of SLC43A2 in GEPIA (Figure 2A, p < 0.05), GSCA (Figure 2B, p < 0.001), TCGA-LIHC unpaired (Figure 2C, p < 0.001) and paired (Figure 2D, p < 0.001) analyses respectively. Besides, immunohistochemical staining from HPA indicated the upregulation of SLC43A2 protein in LIHC [Figures 2E,F, Normal tissue: Weak (<25%), LIHC Tumor: Moderate (25%–75%)]. High expression of SLC43A2 had higher levels of AFP (25 vs. 4 ng/ml, p = 0.012), while T stage, N stage, M stage, age, Albumin (g/dl), or Body Mass Index (BMI) had no significant differences (Table 1).
