Overexpression of β-Catenin Induces Cisplatin Resistance in Oral Squamous Cell Carcinoma.

ABSTRACT: Abnormal expression of β-catenin contributes to tumor development, progression, and metastasis in various cancers. However, little is known about the relationship between abnormal expression of β-catenin and cisplatin chemotherapy in oral squamous cell carcinoma (OSCC). The present study aimed to investigate the effect of β-catenin on OSCC cisplatin resistance and evaluated the drug susceptibility of stable cell lines with β-catenin knockin and knockdown. In this study, we found that higher expression level of β-catenin can be observed in CDDP-treated cell lines as compared with the control group. Furthermore, the expression levels of β-catenin increased in both a concentration- and time-dependent manner with the cisplatin treatment. More importantly, the nuclear translocation of β-catenin
