Core Tip

Core Tip: Post-translational modifications act as dynamic molecular codes that steer dental-derived mesenchymal stem cells through a continuum from periodontal regeneration to oral squamous cell carcinoma stem-cell plasticity. This review integrates single-cell and spatial multi-omics evidence to map a sequential cascade-acetylation, crotonylation, phosphorylation, trimethylation, ubiquitination and N6-methyladenosine RNA methylation-that reprograms lineage commitment, immune evasion and therapy resistance. Identifying tractable post-translational modification enzymes (e.g., general control non-depressible 5, enhancer of zeste homolog 2, methyltransferase-like 3) clarifies actionable levers for regeneration and oncology.
