Since the publication of this paper the authors have noted an error in Figures 2b and c. The position of the western blot labels ‘siNC’and ‘siSPAG5’ was incorrect. This has now been rectified, the correct figure is shown below and the corrected article appears online together with this corrigendum.

SPAG5 knockdown efficiency in cervical cancer cell lines. (a) Western blot of siRNA specific to SPAG5 knockdown efficiency in SiHa cells (left), gradient analysis (middle); mRNA expression (right) was detected by qRT-PCR. (b) Transient knockdown reflected in levels of SPAG5 protein (left) and mRNA (right) in HeLa cells. (c) SPAG5 expression in shSPAG5 lines detected by western blotting (right) and qRT-PCR (left)
