As shown in Fig. 1J and K, GBAP1 expression was significantly overexpressed in HCC tissues, which was consistent with the data form GEO dataset GSE45436 (Fig. 3A), TCGA data (Fig. 3B) and GEO dataset GSE84005 (Additional file 1: Fig. S2A). This evidence concerns the gene GBA1LP and hepatocellular carcinoma.
