Fig. 7. Upregulation of TRIM25 in HCC correlates with poor prognosis.
a Comparison of the TRIM25 mRNA level between HCC and normal tissues in TCGA database. Normal tissues/ Primary tumor tissues: n = 50/371, maximum = 6.396/20.772, upper quartile = 3.461/10.888, median = 2.299/7.382, lower quartile = 1.608/4.781, minimum = 0.925/0.936. Statistical significance was assessed using two-tailed Student’s t-test. b, c Representative images (b) of IHC staining and the relative IHC scores (c) of TRIM25 in HCC tissues and adjacent normal tissues. Scale bar, 50 μm. Data represent the mean ± SEM (adjacent normal tissues, n = 45; HCC tissues, n = 45). The IHC score ranging from 0 to 8 was calculated by multiplying the staining extent score with the staining intensity score. Statistical significance was assessed using two-tailed Student’s t-tests. d, e Representative images of IHC (d) and Kaplan–Meier analysis of overall survival probability (e) of TRIM25 levels in HCC patients. Scale bar, 50 μm. The statistical significance was assessed using two-sided log-rank test according to HCC patients with low or high expression of TRIM25(TRIM25 low expression patients, n = 45; TRIM25 high expression patients, n = 45). f, g The overall survival (f) and disease-free survival probability (g) were compared between TRIM25 High (n = 146) and Low expression (n = 218) in HCC patients from TCGA cohort. h, i Disease/progression-free survival (h) and overall survival (i) were compared between HCC with TRIM25 amplification (n = 11) and without TRIM25 amplification (n = 594) in HCC patients from cBioPortal database. For e, f, g, h and i, the statistical significance was assessed using two-sided log-rank test, log-rank p values were shown.
