“Addition of 10 μM ZnCl2 enhanced the increase in cell lethality induced by 10 μM ARA.”
“The Zn(2+) chelators attenuated the ARA-induced increase in intracellular Zn(2+) level while ARA significantly increased intracellular Zn(2+) level in the presence of 3 μM ZnCl2 , suggesting the involvement of external Zn(2+).”
