Abstract:
Objective To investigate the expression pattern of linc00346 and E2F2, and its prognostic value on liver cancer. Methods Gene expression profile data of patients with liver cancer was downloaded from the cancer genome atlas (TCGA) database. Paired t test was used to evaluate the differential expression of linc00346 and E2F2 from tissues and matched adjacent normal tissues. Co-expression analysis of linc00346 and E2F2 was performed using Pearson correlation. Log-Rank test and Cox proportional hazards regression were used to estimate prognostic value of linc00346 and E2F2. Results linc00346 and E2F2 expression were upregulated in liver cancer tissue specimens (all P＜0.05), and fold change was 2.24 and 3.72, respectively. Pearson coefficient was 0.20 (P＜0.001). Patient with linc00346 and E2F2 high expression had a 1.77 (95 % CI: 1.23-2.55) and 2.19 (95 % CI: 1.51-3.17) times higher hazard of death than those with linc00346 and E2F2 low expression, respectively. However, only E2F2 was significantly associated with the prognosis of liver cancer in multiple Cox regression. Conclusions linc00346 and E2F2 expressions are upregulated in liver cancer tissues, and patients with linc00346 and E2F2 high expressions has poor prognosis. It is of great significance to discover linc00346 and E2F2 as a novel therapeutic target for liver cancer.
