Figure 1. GSTZ1‐1 expression is generally downregulated in human HCC tissues and correlates with poor survival of HCC patients.

• A
  GSTZ1 mRNA expression in HCC and paired non‐tumor tissues from The Cancer Genome Atlas (TCGA) Liver Hepatocellular Carcinoma (LIHC) dataset.
• B
  GSTZ1 mRNA expression in increasing pathologic stages of HCC based on data from TCGA database. The box‐and‐whisker plots display the medians (horizontal lines), interquartile ranges (boxes), and minimum and maximum values (whiskers) of the mRNA expression data. The n indicates the number of samples.
• C
  Overall survival of HCC patients with high (> 25 percentile) or low (≤ 25 percentile) mRNA expression of GSTZ1‐1, based on TCGA data.
• D, E
  GSTZ1 mRNA (D) and protein (E) expression in 40 cases of HCC and paired non‐tumor tissues.
• F
  Representative images (left) and quantification (right) of GSTZ1‐1 immunohistochemical staining in 12 cases of HCC and paired non‐tumor tissues. Scale bars: 100 μm.

Data information: **P < 0.01, ***P < 0.001, Student's t‐test (A, D, and F) or one‐way ANOVA followed by the Tukey test (B) or Gehan–Breslow–Wilcoxon test (C). Abbreviations: N, non‐tumor; T, tumor; RPKM, reads per kilobase per million mapped reads; RSEM, RNA sequencing by expectation maximization.Source data are available online for this figure.
