To determine the clinical significance of LECT2 expression for HCC patients in our study, we used the Gene Expression Omnibus (GSE45436) and The Cancer Genome Atlas databases to analyzed the LECT2 and angiogenesis biomarker gene expression correlation (CD34) in HCC patients (Fig. 6a–e); Supplementary Fig. S3). The gene discussed is CD34; the disease is hepatocellular carcinoma.
