Purpose: This study aimed to analyze expression profiles of long noncoding RNAs (lncRNAs) in lung adenocarcinoma.
Methods: lncRNA microarray technology was employed to detect lncRNA profiles of 3 pairs of lung adenocarcinoma tissues and adjacent tissues.
Results: We found 134 upregulated lncRNAs and 460 downregulated lncRNAs in lung adenocarcinoma tissues compared to adjacent tissues. Among them, LINC00152, LINC00691, and LINC00578 showed the most significant changes of upregulation, while LINC00668, LINC00710, and LINC00607 showed the most significant changes of downregulation. Fluorescent quantitative polymerase chain reaction (PCR) analysis of tissue samples from an additional 90 patients with lung adenocarcinoma showed significantly increased levels of LINC00152, LINC00691, and LINC00578 and decreased levels of LINC00668, LINC00710, and LINC00607 in lung adenocarcinoma tissues. In addition, LINC00578 was closely associated with the existence of metastasis of lung adenocarcinoma, but the other 5 lncRNAs showed no significant correlation with clinicopathologic characteristics such as age, gender, tumor stage, and the existence of metastasis. Further follow-up study showed that LINC00578 expression was closely associated with the survival of patients with lung adenocarcinoma.
Conclusion: We revealed the expression profiles of lncRNAs in lung adenocarcinoma and identified LINC00578 as a promising biomarker and therapeutic target for lung adenocarcinoma.
