Figure 3: Melatonin effect on cystine uptake. NSC cells were treated with 10nM Melatonin overnight. Cystine uptake was detected using a cyanide: nitroprusside system and read at 521nm. Cystine uptake is expressed as pmols/min/mg protein. *p≤0.05 using the paired student t-test. All experiments were n=3. |
