General Information

General Information Comment Organism
malfunction influence of HS3ST2 overexpression on the CSC phenotype in breast cancer cell lines representative of the triple-negative (MDA-MB-231) and hormone-receptor positive subtype (MCF-7). The CD44+/CD24-/low phenotype is significantly reduced in MDA-MB-231 cells after overexpression of the enzyme, remaining unaltered in MCF-7 cells. Colony and spheroid formation are increased after HS3ST2 overexpression in MCF-7 cells. The phenotypic changes are associated with complex changes in the expression of the stemness-associated notch and Wnt-signaling pathways constituents, syndecans, heparanase and Sulf1. Heparan sulfotransferase subtype-specific impact of HS modifications on the CSC phenotype of triple-negative and hormone receptor positive breast cancer model cell lines. In MDA-MB-231 cells, ALDH1 activity increases from 2.88% in the control transfected cells to 5.36% after overexpression of HS3ST2 overexpressing cells Homo sapiens
metabolism high sulfation degree of heparan mediates functional interactions with positively charged amino acids in proteins. 2-O-sulfation of iduronic acid and 3-O-sulfation of glucosamine in heparan sulfate (HS) are mediated by the sulfotransferases HS2ST and HS3ST, respectively, which are dysregulated in several cancers. Both sulfotransferases regulate breast cancer cell viability and invasion. The syndecan family of HSPGs and the Notch pathway are part of the regulatory circuit of HS sulfotransferases. The expression levels of several genes are altered by overexpression of HS3ST2, breast cancer cell transcriptome analysis, overview Homo sapiens
physiological function the sulfotransferase HS3ST2 regulates breast cancer cell viability and invasion. It catalyzes the 3-O-sulfation of glucosamine in heparan sulfate. 3-O-sulfation of glucosamine is the rarest heparan sulfate (HS) modification step, yet strongly mediating selective cellular processes Homo sapiens
