PKNOX2 suppresses lung cancer cell proliferation by inhibiting the PI3K/AKT/mTOR axis.

ABSTRACT: PBX/knotted 1 homeobox 2 (PKNOX2) has been implicated in tumorigenesis; however, its role in lung cancer (LC) remains unknown. The present study thus aimed to examine the expression, regulation, function and clinical implication of PKNOX2 in LC. A series of experiments were performed, including Cell Counting Kit-8 assay, cell cycle analysis, wound-healing assay, Transwell assay, methylation-specific PCR and western blotting. Bioinformatics analysis revealed that PKNOX2 was a LC-related gene, and a decrease in its expression was found in LC tissues from three public datasets. The results of reverse transcription-quantitative PCR assays also confirmed that PKNOX2 mRNA expression was markedly downregulated in LC tissues (n=60, P<0.01) and in five types of LC cell lines, and this was associate
