Prognostic model of AU-rich genes predicting the prognosis of lung adenocarcinoma.

ABSTRACT:

Background

AU-rich elements (ARE) are vital cis-acting short sequences in the 3'UTR affecting mRNA stability and translation. The deregulation of ARE-mediated pathways can contribute to tumorigenesis and development. Consequently, ARE-genes are promising to predict prognosis of lung adenocarcinoma (LUAD) patients.

Methods

Differentially expressed ARE-genes between LUAD and adjacent tissues in TCGA were investigated by Wilcoxon test. LASSO and Cox regression analyses were performed to identify a prognostic genetic signature. The genetic signature was combined with clinicopathological features to establish a prognostic model. LUAD patients were divided into high- and low-risk groups by the model. Kaplan-Meier curve, Harrell's concordance index (C-index), calibration curves and
