According to the GEPIA2 website, we observed the prognostic value of LINC00673 in 33 different cancer types and found that high expression of LINC00673 showed poor prognostic impacts on four cancer types, including adrenocortical carcinoma (ACC), kidney renal clear cell carcinoma (KIRC), thymoma (THYM), and HCC (Figure 1A, left panel) and Kaplan–Meier curves for overall survival (OS) of patients with HCC are shown in the right panel of Figure 1A. We also observed significantly higher LINC00673 transcripts in HCC compared to noncancerous tissues (Figure 1B). This evidence concerns the gene LINC00511 and adrenal cortex carcinoma.
