For additional information: By radioimmunoassay, we found that Tyr-MIF-1 -like immunoreactivity Tyr-MIFLI was first consistently detectable in plasma when the rat was 5 days old, and then gradually increased to adult concentrations by day In male rats, the levels remained relatively constant for the next 21 months. At 6 months of age, however, the concentrations in females decreased by half and by 21 months of life were only about a third of the concentrations found at day 15 or in age-matched males. The differences with age were not due to the length of time of storage of the samples, because another group of rats 1 month old was killed on the same day as 5-day-old rats and still showed several times more Tyr-MIFLI in the plasma; again, no differences were found between male and female rats at either 5 days or 1 month. A single injection of estradiol followed by progesterone lowered the concentrations in 1-month-old male rats.Abstract. The concentrations in plasma of the biologically active endogenous peptide Tyr-MIF-1 (Tyr-Pro-Leu-Gly-NH2) have not been measured during.
