dc.description.abstract | Binge drinking (BD) is an especially pro-oxidant pattern of alcohol consumption,
particularly widespread in the adolescent population. In the kidneys, it affects the
glomerular filtration rate (GFR), leading to high blood pressure. BD exposure also
disrupts folic acid (FA) homeostasis and its antioxidant properties. The aim of this
study is to test a FA supplementation as an effective therapy against the oxida-
tive, nitrosative, and apoptotic damage as well as the renal function alteration oc-
curred after BD in adolescence. Four groups of adolescent rats were used: control,
BD (exposed to intraperitoneal alcohol), control FA-supplemented group and BD
FA-supplemented group. Dietary FA content in control groups was 2 ppm, and
8 ppm in supplemented groups. BD provoked an oxidative imbalance in the kid-
neys by dysregulating antioxidant enzymes and increasing the enzyme NADPH
oxidase 4 (NOX4), which led to an increase in caspase-9. BD also altered the renal
nitrosative status affecting the expression of the three nitric oxide (NO) synthase
(NOS) isoforms, leading to a decrease in NO levels. Functionally, BD produced a
hydric-electrolytic imbalance, a low GFR and an increase in blood pressure. FA
supplementation to BD adolescent rats improved the oxidative, nitrosative, and
apoptotic balance, recovering the hydric-electrolytic equilibrium and blood pres-
sure. However, neither NO levels nor GFR were recovered, showing in this study for the first time that NO availability in the kidneys plays a crucial role in GFR
regulation that the antioxidant effects of FA cannot repair. | es |
