Abstract

Evidence indicates that Benzo(a)pyrenediol-epoxide (BPDE) can damage lung cells, resulting in carcinogenesis with complex mechanisms. We aimed to explore the genes and pathway variations in this process. First, the key gene was screened out and identified through data mining, and then, it was in turn validated by bioinformatics analysis and experimental methods. Consequently, 106 up-regulated and 260 down-regulated differentially expressed genes were yielded, which were enriched in various pathways, such as Cell cycle, and p53 signaling pathway. Then, KIF11 was identified as the key gene. Overexpression of KIF11 in lung cancer had a correlation with advanced pathological grade, advanced T stage, and presence of lymph node metastasis, which predicted poor prognosis. In summary, the present study revealed that KIF11 might be a key gene in the tumorigenesis of BPDE-related lung cancer, raising the possibility of KIF11 as a target for BPDE-induced lung cancer prevention and therapy.
