Cervical cancer is still a leading cause of tumor death in women across the world. Small nuclear ribonucleoprotein polypeptides B and B1 (SNRPB) gene encodes the components of the core spliceosomal machinery, and regulates the development of several types of cancers. However, its function in cervical cancer progression remains unclear. In the study, we found that SNRPB was highly expressed in human cervical cancer tissues and in cervical cancer cell lines. Meanwhile, SNRPB knockdown using shRNA in cervical cancer cells markedly reduced the cell proliferation, migration and invasion. Furthermore, the increased percentage of cells in G2/M phase and apoptotic cell death was detected in cervical cancer cells with SNRPB knockdown, suggesting that SNRPB might contribute to cervical cancer growth. Moreover, we found that SNRPB could directly interact with p53, and the interaction showed an essential role in modulating cervical cancer cell proliferation, migration, invasion and apoptosis. In xenograft model, the knockdown of SNRPB exerted effectively anti-cervical cancer ability characterized by the reduced tumor volume and weight, and a remarkable reduction in KI-67 expression. Improved expression of p53 validated the in vitro findings. Therefore, SNRPB might be a potent therapeutic target in cervical cancer through interacting with p53.
