Abstract:
Objective:To explore the molecular mechanisms underlying Nobiletin’s inhibition of OS growth.Methods:Merge GSE70414,GSE36001,and GSE14789 from the GEO database,analyze the merged dataset using R software to obtain differentially expressed genes,and perform KEGG and GO enrichment analysis on the differentially expressed genes.Retrieve the target genes of Nobiletin from the swiss,TCMSP,SEA,and SuperPred databases,and then obtain the intersection genes of Nobiletin target genes and differentially expressed genes in OS.Using Cytoscape software to establish PPI network to determine the Hub genes.Next,Lasso regression analysis will be used to construct a diagnostic model,and the Hub genes diagnostic model will be validated using an external dataset.Molecular docking analysis will also be used to determine the binding activity between Nobiletin and Hub genes.Finally,the effect of Nobiletin on the proliferation of OS cells was evaluated using CCK-8 and colony formation on OS cell lines.RT-qPCR was used to analyze the changes in mRNA levels of Hub genes after Nobiletin was applied to OS cells.Results:Differential analysis successfully screened 1 260 differentially expressed genes,including 639 up-regulated genes and 621 down-regulated genes.KEGG signaling pathways include Cytokine-cytokine receptor interaction,Chemokine signaling pathway,Transcriptional misregulation in cancer,ect.GO functional enrichment analysis results involve protein binding,gene transcription,kinase activity,etc.The construction of PPI identified three hub genes,PIK3CG,FPR1,and KDR.The construction and validation of the hub genes diagnostic model showed that hub genes are helpful for the diagnosis of OS patients,and their high expression was closely related to poor prognosis in OS patients.The molecular docking results showed that nobiletin has good binding activity with hub genes.CCK-8 and colony formation capacity results showed that nobiletin inhibited the growth of OS cells.RT-qPCR results showed that treatment of OS cells with nobiletin significantly reduced the mRNA level of PIK3CG.Conclusion:Nobiletin can significantly inhibit the growth of OS cells,and its inhibition of OS cell growth may be related to PIK3CG.
