Abstract

Notch1 signaling is essential for tissue development and tumor progression. This signaling pathway has also been implicated in oral leukoplakia (OL) and oral squamous cell carcinoma (OSCC). However, the role of Notch1 expression in OL and its malignant transformation is unknown. This study aimed to examine the Notch1 expression patterns by immunohistochemistry (IHC) in a cohort of 78 Chinese patients with OL and to analyze the relationship between the patterns and progression of OL to OSCC. Strong Notch1 staining was observed in 10 (13%) of the 78 OL patients, but it was not associated with any of the clinicopathological parameters. However, we observed membranous Notch1 expression in 24 (31%) of the OL samples. Membranous Notch1 expression was significantly associated with the severity of dysplasia (P<0.001) and development of OSCC (P=0.003). By multivariate analysis, membranous Notch1 expression was found to be the only independent factor for OSCC development in the patient population (P=0.019). Among the 24 patients with membranous Notch1 expression, 11 (46%) developed OSCC compared to 8 (15%) of the 54 patients without such expression (P=0.001, determined by log‑rank test). Furthermore, we established a 4‑nitroquinoline‑1‑oxide (4NQO)‑induced murine OSCC model and studied the Notch1 expression patterns in different stages of carcinogenesis. We observed that the extent of expression of membranous Notch1 increased during carcinogenesis. These data indicated a relationship between membranous Notch1 expression and OSCC risk in patients with OL and suggested that membranous Notch1 served as a biomarker for assessing OSCC risk.
