WTAP Contributes to Periodontitis Pathogenesis by Promoting PDLSC Senescence and Impairing Osteogenic Differentiation via m6A-Dependent Regulation of TP53BP1.

ABSTRACT:

Background

Periodontitis, a chronic inflammatory disease, represents the primary cause of tooth loss in Chinese adults. Wilms tumor 1-associating protein (WTAP) is a key component of the N6-methyladenosine (m6A) methyltransferase complex, and has an unclear role in periodontitis pathogenesis, particularly concerning its regulatory functions in periodontal ligament stem cells (PDLSCs).

Methods

The target gene was identified through the GES260558 dataset and Genecards database. Gene expression was measured using reverse transcription-quantitative PCR (RT-qPCR) and western blot. Periodontitis-derived PDLSCs (P-PDLSCs) were isolated and identified by alkaline phosphatase (ALP) staining, oil red O staining, and flow cytometry. Malondialdehyde (MDA), superoxide dismutase (SOD), an
