COMMENTARY
LITERATURE
medicine
the expression profiles of isoform ST6GalNAc VI among 20 renal cancer cell lines correlates clearly with those of disialylgalactosylgloboside, suggesting that the sialyltransferase involved in the synthesis of disialylgalactosylgloboside in the kidney is ST6GalNAc-VI. ST6GalNAc-VI and disialylgalactosylgloboside are found in proximal tubule epithelial cells in normal kidney tissues, while they are downregulated in renal cancer cell lines and cancer tissues
