Core Tip
Core Tip: This study explored the expression of palmitoyl-protein thioesterase (PPT)1 in oral squamous cell carcinoma (OSCC) using immunohistochemistry and H-score quantification. A strong positive correlation was observed between PPT1 expression and tumor grade, while a negative correlation was seen with age. These findings suggest that PPT1 serves as a novel prognostic and therapeutic biomarker, especially in younger patients and advanced OSCC cases. The study highlights the potential of integrating molecular biomarkers like PPT1 with conventional histopathological evaluation to guide personalized treatment strategies in OSCC.
