Human leptin deficiency caused by a missense mutation: multiple endocrine defects, decreased sympathetic tone, and immune system dysfunction indicate new targets for leptin action, greater central than peripheral resistance to the effects of leptin, and spontaneous correction of leptin-mediated defects
The reaction mixture (1 ml) containing Lockes buffer (pH 7.4), 0.2 ml homogenate and 10 l of DCFH-DA (5 mM) was incubated for 45 min at room temperature and the fluorescence intensity of DCF was recorded by excitation at 485 nm and emission at 535 nm using a Synergy TM 2 Multi-function Microplate Reader (Bio-Tek Instruments Inc., Winooski, Vermont, USA)
