To identify reliable diagnostic biomarkers and characterize molecular subtypes of periodontitis by integrating single-cell RNA sequencing, machine learning models, and Mendelian randomization.
Analyzed multiple Gene Expression Omnibus datasets (GSE164241, GSE10334, GSE16134, GSE23586, GSE106090) to evaluate cellular communication, functional enrichment, and molecular subtyping.
Constructed diagnostic models using 106 combinations across 11 machine learning algorithms, prioritized candidate genes via Mendelian randomization, and validated findings via RT-qPCR in gingival tissues from 13 stage III/IV periodontitis patients and healthy controls.
Identified four novel periodontitis subtypes (fibroblast-dominant, myeloid-dominant, quiescent, and mixed), with myeloid-dominant and mixed subtypes displaying heightened inflammatory microenvironments.
Screened five key genes (IGFBP4, IL1B, LAPTM5, PSAP, SRGN) and experimentally confirmed significant differential expression of IGFBP4, IL1B, and LAPTM5 in stage III/IV periodontitis tissues compared to controls (p < 0.001).
