Figure Lengend Snippet: Identification of five biomarkers in HCC. (A) mRNA expression of DDX55, RAB10, RAB7A, TAF1B and TAF3 in HCC and normal tissues from TCGA. Overall survival curves in patients with HCC with high or low expression of (B) DDX55, (C) RAB10, (D) RAB7A, (E) TAF1B and (F) TAF3 from TCGA dataset. The best cut-off value for each gene was obtained using the X-tile software. (G) mRNA expression of DDX55, RAB10, RAB7A, TAF1B and TAF3 in HCC and paired paracancerous tissues from 10 patients with HCC, assessed using reverse transcription-quantitative PCR. (H) Immunohistochemical images of DDX55, RAB10 and RAB7A in HCC and normal tissues obtained from the HPA. (I) Protein expression of DDX55, RAB10, RAB7A, TAF1B and TAF3 in HCC and paired paracancerous tissues from 10 patients with HCC, evaluated using western blot analysis. The figure on the right is a relative semi-quantitative histogram of protein expression. The gray values were obtained by ImageJ and analyzed using GraphPad Prism. (J) Cell Counting Kit-8 curves after knockdown of RAB10, RAB7A and TAF3 in Huh7 cells by siRNA. *P<0.05; **P<0.01; ***P<0.001; ****P<0.0001.
