Abstract:
Objective To analyze the gene expression profiles in response to ΔNp63α overexpression, and screen the potential target genes or signal pathways regulated by ΔNp63α. Methods To generate ΔNp63α overexpressed SiHa cells ( SiHa-ΔNp63α) and the control cells ( SiHa-NC) , recombinant lentivirus transfection was performed. Microarray was applied to detect the change of gene expression profiles, and the results were analyzed with bioinfor-matic software. Quantitative real-time PCR was used to validate the expression levels of selected genes. Results Among the 1405 differentially expressed genes which were statistically significant, >1. 5 fold increase or reduce of gene expression, 843 were up-regulated and 562 were down-regulated in SiHa cells with ΔNp63α overexpression. The genes were mostly involved in cell development,cycle regulation, signal transduction, communication, adhe-sion, metastasis and invasion, etc. The involved signal pathways consisted of antigen processing and presentation, cytokine-cytokine receptor interaction, cell adhesion, complement and coagulation cascades, and so on. Conclu-sion The research on the potential target genes or mediated signal pathways regulated by ΔNp63α could be helpful to explain the development of cervical cancer.
