Abstract

Objective: To investigate the expression of long-chain non-coding RNA MINCR (LncRNAMINCR) and Cyclin-Dependent Kinase 2 (CDK2) mRNA in primary hepatocellular carcinoma, and to analyze the relationship between its expression and clinical pathological parameters and prognosis of hepatocellular carcinoma.

Methods: Seventy-five surgically resected primary hepatocellular carcinoma tissues and paracancerous tissues were selected. Real-time PCR was used to detect the expression of LncRNA-MINCR and CDK2 mRNA in hepatocellular carcinoma tissues and adjacent tissues. The relationship of clinicopathological parameters and prognosis between hepatocellular carcinoma and LncRNA-MINCR and CDK2 mRNA were analyzed. Pearson correlation coefficient describes the correlation between LncRNA-MINCR and CDK2 mRNA.

Results: The expression of LncRNA-MINCR and CDK2 mRNA in primary hepatocellular carcinoma tissues was higher than that in the adjacent tissues [(5.51±0.62) vs (1.62±0.51), (4.52±0.73) vs (1.85±0.95), P<0.05]. The expression of LncRNA-MINCR in the primary hepatocellular carcinoma group was positively correlated with CDK2 mRNA (r=0.352, P<0.05), and the expression of LncRNA-MINCR in the paracancerous tissue group was not correlated with CDK2 mRNA (r=0.024, P>0.05). LncRNA-MINCR expression was associated with TNM staging, lymph node metastasis, and cirrhosis (P<0.05). CDK2 mRNA expression was associated with tumor diameter, TNM stage, lymph node metastasis, and serum alpha-fetoprotein levels (P<0.05). The 3-year survival rate of patients with high expression of LncRNAMINCR was lower than that of LncRNA-MINCR low expression group [53.49% vs 77.38%, 2=13.024, P<0.05). The 3-year survival rate of patients with high CDK2 mRNA expression was lower than that of CDK2 mRNA low expression group [51.29] % vs 80.38%, 2 = 10.15, P < 0.05].

Conclusion: The expression of LncRNA-MINCR and CDK2 mRNA in primary hepatocellular carcinoma tissues increased significantly. The two play a synergistic role in the invasion, invasion and metastasis of hepatocarcinoma cells. High expression of LncRNA-MINCR and CDK2 mRNA indicates poor prognosis in patients with hepatocellular carcinoma.

Keywords: Malignant tumor, primary hepatocellular carcinoma, LncRNA-MINCR, CDK2 mRNA, clinicopathological parameters, prognosis, gene expression.
