Comprehensive analyses of prognostic biomarkers and immune infiltrates among histone lysine demethylases (KDMs) in hepatocellular carcinoma.
Background: Histone lysine demethylases (KDMs) are closely related to the occurrence and development of different tumors through epigenetic mechanisms. However, the prognosis and immune infiltration of KDMs in hepatocellular carcinoma (HCC) remain undefined.
Methods: In the current study, we analyzed the expression of KDMs on HCC patients using the Oncomine, GEPIA, UALCAN, Kaplan-Meier Plotter, cBioPortal, GeneMANIA, STRING, Metascape, GSEA, and TIMER databases. Finally, we investigated KDM expression in HCC by qRT-PCR, Western blotting, and IHC.
Results: We found that KDM3A/3B/5A/5B and KDM6A were upregulated in HCC patients, while KDM6B and KDM8 were downregulated. The high expressions of KDM1A/2B/3B/5B/5C were markedly related to tumor stages and grades of HCC patients. The abnormal expression of KDM1A/1B/3A/4A/5A/5C/6A/6B/7A and KDM8 were associated with HCC patients' prognosis. Also, we found that HCC tissues presented higher expression levels of KDM1A/2A/5A/5B and lower expression levels of KDM6B. The function of KDMs was primarily related to the histone demethylase activity and cell cycle, p53 signaling pathway, pathways in cancer, transcriptional mis-regulation in cancer, viral carcinogenesis, and FoxO signaling pathway. Furthermore, we indicated that the pathways most involved were the mitotic spindle and DNA repair. Additionally, we found that the expression of KDM1A/1B/3A/4A/5B/5C and KDM6A were significantly correlated with HCC immune infiltration.
Conclusions: Overall, our current results indicated that KDM1A/1B/3A/4A/5B/5C and KDM6A could be novel prognostic biomarkers and provide insights into potential immunotherapy targets to HCC patients.
期刊介绍：
The Annals of the Entomological Society of America exists to stimulate interdisciplinary dialogue across the entomological disciplines and to advance cooperative interaction among diverse groups of entomologists. It seeks to attract and publish cutting-edge research, reviews, collections of articles on a common topic of broad interest, and discussion of topics with national or international importance. We especially welcome articles covering developing areas of research, controversial issues or debate, and topics of importance to society. Manuscripts that are primarily reports of new species, methodology, pest management, or the biology of single species generally will be referred to other journals of the ESA. The most important criteria for acceptance are quality of work and breadth of interest to the readership.
