O-GlcNAcylation of cofilin promotes breast cancer cell invasion

Abstract

Background:O-GlcNAcylation plays important roles in breast cancer metastasis, but the underlying mechanism is not fully known. Results: Cofilin is O-GlcNAcylated at Ser-108, which is required for its proper localization in invadopodia and is implicated in promoting breast cancer cell invasion. Conclusion: O-GlcNAcylation plays an important role in fine-tuning the regulation of cofilin. Significance: These findings reveal the implications of aberrant cofilin O-GlcNAcylation in cancer metastasis. © 2013 by The American Society for Biochemistry and Molecular Biology, Inc.
