Using an O2 consumption rate of 1 fmol/min/cell, which was not observed in any transformant among 158 derived from individuals 20 weeks (fetal) to 37 years of age, as a cut-off to identify respiratory-deficient clones, 11 such clones were found among 198 transformants derived from individuals 39-103 years of age.

Large-scale screening of the mtDNA main control region in leukocytes from subjects of an Italian population revealed a homoplasmic C150T transition near an origin of heavy mtDNA-strand synthesis in approximately 17% of 52 subjects 99-106 years old, but, in contrast, in only 3.4% of 117 younger individuals (P = 0.0035).

Finally, formyl-methionyl-leucyl-phenylanaline (FMLP)-triggered O2- release was reduced in all elderly groups, while depression of O2- production was seen in subjects between the age of 86 and 104 years using phorbol 12-myristate 13-acetate (PMA) as agonist.
