To understand the expression pattern of LINC00844 in different tumours, we extracted LINC00844 from 31 kinds of tumours from Gene Expression Profiling Interactive Analysis (GEPIA) (http://gepia.cancer-pku.cn/) and found that LINC00844 expression was low in most tumours, including HCC (Fig. 1B). The gene discussed is LINC00844; the disease is hepatocellular carcinoma.
