Changes in heparan sulfate sulfotransferases and cell-surface heparan sulfate during SKM-1 cells granulocytic differentiation and A549 cells epithelial-mesenchymal transition

Changes in heparan sulfate sulfotransferases and cell-surface heparan sulfate during SKM-1 cells granulocytic differentiation and A549 cells epithelial-mesenchymal transition:

Abstract

Heparan sulfate (HS) with various sulfation patterns is one of important modulators of cancer cell fate through interacting with numerous growth factors. Here we found HS 2-O sulfotransferase 1 (HS2ST1) was downregulated at both mRNA and protein levels during granulocytic differentiation of SKM-1 leukemia cells and also HS (glucosamine) 3-O sulfotransferase 3A (HS3ST3A) in epithelial-mesenchymal transition (EMT) of A549 lung cancer cells, meanwhile, cell-surface HS recognized by anti-HS antibody was also changed in both cancer cell lines. Further, HS3ST3A was negatively correlated with the in vitro cell metastasis capability of A549 cells confirmed by RNA interference technology, wound-healing assay and in vitro Matrigel invasion assay. Together, specific HS sulfotransferases may serve as molecular markers and targets for cancer treatment.
