Overexpression of Rspo2 increased, whereas Rspo2 silencing decreased the expression of LGR4, leading to subsequent phosphorylation of LRP6 and nuclear translocation of β-catenin in TSCC cell lines.
High CILA1 expression levels and low levels of phosphorylated β-catenin were closely associated with cisplatin resistance and advanced disease stage, and were predictors of poor prognosis in TSCC patients.
Taken together, our findings suggested that RAGE blockade+cisplatin improved chemotherapeutic effects by reducing autophagy and regulating Wnt/β-catenin to suppress the progression of TSCC.
Our results suggest nicotine may promote tongue squamous carcinoma cells progression by activating the Wnt/β-catenin and Wnt/PCP signaling pathways and may play a significant role in the progression and metastasis of smoking-related TSCC.
These results suggest that FHL2 overexpression could contribute to the growth, proliferation, invasiveness, and metastasis of human tongue squamous cell carcinoma; furthermore, its function in TSCC might be related with the upregulation of NF-кB and β-catenin expressions.
The possible underlying mechanism of RhoA depletion on TSCC cell line was also evaluated by determining the expression of Galectin-3 (Gal-3), β-catenin, and matrix metalloproteinase-9 (MMP-9) in vivo.
Ezrin is often overexpressed in primary tongue SCCs and may have an important role in their growth, migration, and invasiveness possibly via its relationship with the E-cadherin/β-catenin complex and the cadherin switch.
