Abstract
Purpose:
Lung cancer is the most malignant respiratory cancer with an undesirable prognosis. Emerging evidence shows that long noncoding RNAs (lncRNAs) can regulate lung cancer development. Currently, the role of LINC00116, a novel lncRNA, in lung cancer is unknown. This study was designed to evaluate the association and clinical significance between the level of LINC00116 and lung cancer.
Materials and Methods:
In the present study, 19 paired lung cancer and non-cancerous adjacent tissues were collected from lung cancer patients to measure the expression of LINC00116 by quantitative reverse transcription-polymerase chain reaction and Microarray analysis (Oncomine and CCLE). Clinicopathological features of patients were obtained to analyze their relationships with LINC00116 expression levels. Kaplan-Meier survival analysis was used to analyze the prognosis.
Results:
LINC00116 expression was upregulated in lung cancer. Furthermore, we found that LINC00116 expression was correlated with pT factor, pN factor, pTNM stage, smoking history, differentiation, and Ki-67 labeling index (p < 0.05). In addition, Kaplan-Meier survival analysis showed that high levels of LINC00116 expression were associated with poorer overall survival (OS), progression-free survival (PFS) and first progression (FP) (p < 0.05) of lung cancer patients.
Conclusions:
Our study provided evidence that LINC00116 is upregulated in lung cancer tissues and can predict poor survival. It might also be able to serve as a therapeutic target. The Clinical Trial Registration number 2022-020.
