摘要
Background:Autophagy-associated long non-coding RNAs(aalncRNAs)take an important position in the tumorigeness of lung cancer,but current researches have not systematically investigated autophagy-associated lncRNAs in lung adenocarcinoma(LUAD).Methods:In this research,RNA-sequences of LUAD patients were downloaded from the TCGA and autophagy-associated genes were obtained from the GSEA website.The Pearson's test was conducted to find the correlation between autophagy-associated lncRNAs and autophagy-associated genes.AalncRNAs with prognostic significance were identified by using Cox and LASSO regression analysis in R,gradually.Risk score model was built to estimate prognosis-associated lncRNAs.Results:A risk score model was established according to the expressions of 7 aalncRNAs(RP11-102K13.5,RP11-1029J19.4,LINC00942,KLHL7-AS1,AC092198.1,C20orf197,LINC01116),and low-risk group was found to have a better prognosis(P<0.001).Next,single gene expression survival analysis show that 4 out of these lncRNAs were significantly associated with the survival of patients.In addition,the AUC value of model reached 0.724,demonstrating the good predictive ability of the model.Conclusion:These aalncRNAs in LUAD might possibly offered biological markers for the diagnosis and therapy of lung adenocarcinoma.
