Leptin Modifies the Rat Heart Performance Associated with Mitochondrial Dysfunction Independently of Its Prohypertrophic Effects

Figure 7

Quantification of oxidized lipids in heart homogenates and isolated mitochondria. Levels of oxidized lipids were measured by TBARS methodology in (a) homogenates after 1, 2, 4, or 4 hours of perfusion with/without leptin. Bars represent the of four independent preparations; vs the control group. (b) Isolated mitochondria. (c) Values of TBARS from homogenates and mitochondria were analyzed by Pearson’s test to identify a correlation between variables. R1 = Pearson’s value for control TBARS in the four time points analyzed; R2 = Pearson’s value for leptin TBARS in the four time points analyzed. Note that the correlation is strong and positive for the leptin group.
