As the most commonly diagnosed lung cancer, non–small cell lung carcinoma (NSCLC) is regulated by many long noncoding RNAs (lncRNAs). In the present study, we found that SH3PXD2A-AS1 expression in NSCLC tissues was upregulated compared with that in normal lung tissues in The Cancer Genome Atlas (TCGA) database. However, the role and molecular mechanism of SH3PXD2A-AS1 in NSCLC progression require further exploration.
The expression of SH3PXD2A-AS1 in NSCLC and normal lung tissues in a TCGA dataset was analysed by using the GEPIA website. K-M analysis was performed to explore the effects of this molecule on the survival rate in NSCLC. The functional characterization of the role and molecular mechanism of SH3PXD2A-AS1 in NSCLC was performed with a series of in vitro and in vivo experiments.
SH3PXD2A-AS1 expression was increased in human NSCLC, and high SH3PXD2A-AS1 expression was correlated with poor overall survival. SH3PXD2A-AS1 overexpression sufficiently promoted tumour cell proliferation and accelerated cell cycle progression in vitro and tumour growth in vivo. Moreover, SH3PXD2A-AS1 interacted with DHX9 to enhance FOXM1 expression, promote tumour cell proliferation and accelerate cell cycle progression.
SH3PXD2A-AS1 promoted NSCLC growth by interacting with DHX9 to enhance FOXM1 expression. SH3PXD2A-AS1 may serve as a promising predictive biomarker for the diagnosis and prognosis of patients with NSCLC.
