SELE and neoplasm: Notably, in an experiment where HepG2 cells expressing the selectin ligand sLex (but not sLea) and HuH7 cells slightly expressing sLea (but not sLex) were injected subcutaneously into nude mice, the inhibition of E‐selectin expression on endothelial cells via cimetidine and amiloride treatment resulted in a significant reduction in HepG2 tumor growth but did not affect HuH7 tumors.
