ST3GAL6 and cancer: The current RNA-seq data indicated no significant changes in the gene expression levels of three α2,3-sialyltransferases, ST3GAL3, ST3GAL4, and ST3GAL6, and α2,6-sialyltransferase, ST6GAL1, all of which are known to be involved in the synthesis of terminal sialylated N-glycan species in untreated and TM-preconditioned cancer cells (Supplementary Table S5).
