Summary : A
25Mg
2+-operated hyper
-activation of ATP synthesis has been investigated in mitochondria (Mt) isolated from iron-rich and iron-poor rat tissues: spleen, liver, skeletal muscle, myocardium, kidneys, brain. Both magnetic (
25Mg) and non-magnetic (
24Mg) magnesium isotopes were separately administered to estimate the degree of the ATP production related to the magnetic isotope effect
(MIE) of
25Mg
2+ as a function of the amount of Mt-endogenous iron ions. A strong but negative (
r \= -0.88) correlation between the
25Mg-MIE degree and
the Mt[Fe
2+] values was found. The physical and biophysical mechanisms behind these phenomena, as well as the possible impact of these data on further biochemical and pharmacological studies involving
25Mg-promoted nuclear spin selectivity in mitochondrial function, are under discussion. |
