Intact beating fetal mouse hearts in organ culture were deprived of oxygen and glucose for up to 4 h, resulting in loss of beating, an 80% fall in ATP, reduction of energy charge from 0.85 to 0.48, and doubling of total nucleoside concentration. Radiolabeled adenine nucleotides were degraded to hypoxanthine and inosine, which were lost from the hearts into the medium during the deprivation period. Adenosine and adenine also appeared in the medium when adenosine deaminase was inhibited. After 24 h of O2 and glucose resupply, ATP returned to 60% of control, and energy charge rose to 0.76. Labeled nucleosides and bases remaining in the heart or exogenous labeled adenine were utilized to resynthesize ATP. [14C]glycine was rapidly taken up by recovering hearts but was not used for de novo adenine nucleotide synthesis. Ability to recover ATP and spontaneous contraction appear related to residual nucleotide and nucleoside content rather than to energy charge.
