SSRP1 silencing inhibits the proliferation and malignancy of human glioma cells via the MAPK signaling pathway

Structure-specific recognition protein 1 (SSRP1) has been considered as a potential biomarker, since aberrant high expression of SSRP1 has been detected in numerous malignant tumors. However, the correlation between the expression level of SSRP1 and glioma remains unclear. The present study attempte...

Zusammenfassung:Structure-specific recognition protein 1 (SSRP1) has been considered as a potential biomarker, since aberrant high expression of SSRP1 has been detected in numerous malignant tumors. However, the correlation between the expression level of SSRP1 and glioma remains unclear. The present study attempted to investigate the role of SSRP1 in the pathogenesis of glioma. In the present study, our data revealed that SSRP1 overexpression was detected in glioma tissues at both the mRNA and protein levels using quantitative real-time RT-PCR and immunohistochemical analysis. We also demonstrated that the upregulated expression of SSRP1 was correlated with the World Health Organization (WHO) grade of glioma. The knockdown of SSRP1 by siRNA not only resulted in the inhibition of cell proliferation, but also significantly inhibited glioma cell migration and invasion. Mechanistic analyses revealed that SSRP1 depletion suppressed the activity of the phosphorylation of the MAPK signaling pathway. In conclusion, the present study indicated that SSRP1 regulated the proliferation and metastasis of glioma cells via the MAPK signaling pathway.
