Following the publication of the original article [1], the author identified an error in Fig. 5. The western blot of Fig. 5D was inadvertently duplicated from the left panel. This occurred when the authors mistakenly overwrote the right panel data with the left panel data while organizing the raw files.

HERC2 promoted the stemness and immune evasion of HCC cells through JAK2/STAT3 signaling. A HERC2 knockout Huh7 cells were treated with 50 ng/ml IL-6 for 24 h and then subjected to RNA-seq analysis. Reactome pathway analysis displayed the most enriched pathways. B-D HERC2-defcient Huh7 cells and HERC2-overexpressing HCC-97 h cells were treated with 50 ng/ml IL-6 (B), 50 ng/ml IL-11 (C), or 20 ng/ml EGF (D), respectively. The phosphorylation of JAK2 and STAT3 was determined by western blot analysis. E HERC2 and STAT3 double-defcient Huh7 cell lines were established. F The cells were treated with 50 ng/ml IL-6 for 24 h. The RT-qPCR assay was used to detect the mRNA expression of cancer stem cell-related genes. G The cells were cultured in a conditioned medium with 100×N2, 50×B27, 20 ng/ml EGF, 10 nmol FGF, 5 µg/ml insulin, and 0.4% BSA for 7 days, scale bars = 100 μm. H The cells were treated with 20 µM sorafenib for 24 h. A fow cytometry assay was used to determine the percentage of apoptotic cells. I Cells were treated with 50 ng/ml IL-6 for 24 h and then subjected to western blot assay for PD-L1 detection. J and K Activated PBMCs were cocultured with HCC cells at the ratio of 4:1 for 24 h. Apoptosis of HCC cells was detected by fow cytometry assay (J). K IFN-γ levels of CD8 + T cells were determined by fow cytometry analysis. NS: not signifcant, **p < 0.01, ***p < 0.001. Data from one representative experiment of three independent experiments are presented
