Fig. 1: High expression of Sec62 promotes early recurrence HCC after curative resection in patients.

a Left: Representative immunohistochemical (IHC) staining for Sec62 in primary HCC tissues with early recurrence and non-recurrence (×200). Right: Percentage of samples showing low (n = 35) or high Sec62 (n = 25) expression in primary HCC with non-recurrence and early recurrence. The P values were determined by the Chi-square or Fisher’s exact tests. b Western blot analysis of Sec62 in HCC patient samples with recurrence (n = 4) or without recurrence (n = 4). c Kaplan–Meier curves for recurrence-free survival of 60 HCC patients according to high and low Sec62 expression determined by the IHC staining index.
