HS2ST1 and neuroblastoma: Knelson et al. reported that high expression levels of mRNA of sulfotransferases, i.e., heparan sulfate 2-O-sulfotransferase 1 (HS2ST1), heparan sulfate 6-O-sulfotransferase 2 (HS6ST2), heparan sulfate 6-O-sulfotransferase 3 (HS6ST3), and N-deacetylase and N-sulfotransferase 2 (NDST2), were correlated with a good prognosis in NB.
