Abstract
Background: This study aimed to evaluate the relationship between LINC00665 expression levels and the risk of hepatocellular carcinoma (HCC) in Chinese Han nationality patients and to explore the influence of LINC00665 dysregulation on the proliferation and migration potential of HCC cells.
Patients and methods: We investigated the expression of LINC00665 in The Cancer Genome Atlas (TCGA) database. Then, we confirmed the expression of LINC00665 in 54 pairs of surgical tissues from HCC patients and in liver cancer cell lines by quantitative real-time polymerase chain reaction. Furthermore, we manipulated the expression level of LINC00665 and examined the cell proliferation and migration abilities of HCC cells.
Results: In the TCGA cohort, a high level of LINC00665 in patients with HCC was significantly associated with tumor stage, tumor differentiation grade, and overall survival. In our HCC patient cohort, overexpression of LINC00665 in patients showed positive correlations with alpha-fetoprotein level, Barcelona Clinic Liver Cancer stage, and tumor differentiation grade. In addition, LINC00665 was upregulated in HCC cells, especially in cells with rapid growth rates and high migration abilities. A new LINC00665 isoform with a length of 1,371 nucleotides was identified in MHCC-97H cells. Interfering with LINC00665 expression weakened the proliferation and migration abilities of HCC cells. In contrast, LINC00665 overexpression enhanced proliferation and migration abilities.
Conclusion: LINC00665 was upregulated in HCC tissues and cells and might be used to predict a poor prognosis of HCC patients. In addition, LINC00665 may promote the malignant progression of HCC by enhancing proliferation and migration capacities.
期刊介绍:
The International Journal of Clinical and Experimental Pathology (IJCEP, ISSN 1936-2625) is a peer reviewed, open access online journal. It was founded in 2008 by an international group of academic pathologists and scientists who are devoted to the scientific exploration of human disease and the rapid dissemination of original data. Unlike most other open access online journals, IJCEP will keep all the traditional features of paper print that we are all familiar with, such as continuous volume and issue numbers, as well as continuous page numbers to keep our warm feelings towards an academic journal.
