Abstract EN

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 could also be observed by confocal microscope analysis.

Stable cell lines with CTNNB1 knockin and knockdown were established to further investigate the potential role and mechanism of β -catenin in the chemoresistance of OSCC in vitro and in vivo.

Our findings indicated that overexpression of β -catenin promoted cisplatin resistance in OSCC in vitro and in vivo.

We confirmed that GSK-3β, C-myc, Bcl-2, P-gp, and MRP-1 were involved in β -catenin-mediated drug resistance.

Our findings indicate that the Wnt/ β -catenin signaling pathway may play important roles in cisplatin resistance in OSCC.
