The cadherin protein CDH19 mediates cervical carcinoma progression by regulating AKT/NF-κB signaling
The cell adhesion protein cadherin 19 (CDH19) has been reported to be involved in various types of cancer, but its role in cervical carcinoma remains unknown. We collected and analyzed the patients’ data using the GEPIA Kaplan-Meier plotter databases. CDH19 was overexpressed in cervical carcinoma cells to assess its effect on cell proliferation and activation of AKT and NF-κB signaling pathways. A xenograft mouse model was established to study the function of CDH19 in vivo. We found that CDH19 expression was significantly downregulated in cervical carcinoma tissues compared to adjacent normal tissues. Patients with high expression of CDH19 had a significantly better overall survival rate than those with low CDH19 expression. CDH19 expression was negatively correlated with the expression of the proliferation marker Ki-67, and overexpression of CDH19 significantly inhibited cervical carcinoma cell proliferation. Furthermore, overexpression of CDH19 suppressed the activation of the AKT and NF-κB signaling pathways, and CDH19-overexpressing cervical carcinoma tumors exhibited significantly slower growth in vivo. CDH19 plays an important role in cervical carcinoma by suppressing both cell proliferation and the activation of AKT and NF-κB signaling pathways. Therefore, CDH19 may be a potential therapeutic target for cervical carcinoma.
