Cell Death and Disease (2018)9:Web page three ofFig. 1 KIF4A expression increases in HCC tissues and cell lines. a KIF4A mRNA expression in liver cancer tissues is higher than that in regular tissues from Oncomine database.

Cell colour and the number above the cell within the decrease panel indicate the top gene rank percentile for the evaluation. Red, upregulated; blue, downregulated. b The mRNA levels of KIF4A from 78 sufferers have been tested by quantitative PCR utilizing paired t-test. c The protein levels of KIF4A in HCC tissues and matched non-cancerous tissues from 18 sufferers with HCC have been determined by western blotting assay. N non-cancerous, C cancer. Fold transform of KIF4A protein with respect to non-cancerous specimens was normalized to GAPDH. The quantification of western blotting is shown in (d). e KIF4A protein expressions in nine HCC cell lines (QGY-7703, BEL-7404, Hepa3B, MHCC-97L, Huh7, PLC/PRF/5, BEL-7405, SMMC-7721, SK-HEP-1), two hepatoblastoma cell lines (HepG2, HepG2.215), and two immortalized liver cell lines (THLE-2 and LO2) were examined by western blotting. f Quantification of KIF4A expressions in different cell lines is shownOfficial journal on the Cell Death Differentiation AssociationHuang et al. Cell Death and Disease (2018)9:Page 4 ofFig. 2 Upregulation of KIF4A is related with poor prognosis in liver cancer. a Immunohistochemical staining of KIF4A protein expression in 136 HCCs and their corresponding non-cancerous tissues. Two representative situations were shown. The scale bar in the left panel is 500 m. The scale bar from the middle and proper panels is 50 m. b KIF4A expression was linked with OS (n = 136, P 0.001) and DFS (n = 136, P 0.001) in line with Kaplan eier analysis. c DPCPX Epigenetic Reader Domain Subgroup analysis for OS (P = 0.009) and DFS (P = 0.005) of HCC patients in TNM stage I. d Subgroup analysis for OS (P = 0.0192) and DFS (P = 0.0149) of HCC individuals in TNM stage II + III + IVOfficial journal with the Cell Death Differentiation AssociationHuang et al.
