Abstract :
Background: Tooth decay (TD) is a multifactorial disorder, and several factors are involved in its etiology. Objective: The present study aimed to unravel the main genes and molecular mechanisms underlying TD. Methods: The dataset GSE1629 in the Gene Expression Omnibus (GEO) database was analyzed to uncover differentially expressed genes (DEGs) in patients with TD compared to patients with sound teeth. A proteinprotein interaction network was built, and the most important clusters, hub genes, transcription factors (TFs), and protein kinases involved in the regulation of TFs were disclosed. Signaling pathways and Gene Ontology terms dysregulated in TD were also identified. Results: A total of 196 DEGs were determined (false discovery rate 0.001; |Log2 fold change| 1). PTPRC, ITGB2, TYROBP, MMP9, CXCL8, CD44, CCL2, C1QB, C3, and SPP1 were considered hub genes. Further, BPTF and MAPK1 were demonstrated to be the highest TFs and protein kinases likely involved in the pathogenesis of TD, respectively. Conclusion: PTPRC, ITGB2, TYROBP, MMP9, CXCL8, CD44, CCL2, C1QB, C3, SPP1, BPTF, and MAPK1 may be regarded as potential markers for the therapeutic purposes of TD.
