Overexpression B4GALNT1 causes deregulation of glycosphingolipid biosynthesis and is reported to be up-regulated in breast cancer stem cells75 at the transcript level, similarly, S100P76, KLK477,78, DRD479, and BAPX180 genes were also reported to be up-regulated in breast and other cancers at mRNA level. This evidence concerns the gene B4GALNT1 and breast cancer.
