| abstractText | Q10 is a class I molecule previously proven to be secreted rather than membrane bound. To measure the amount of Q10 in various mouse sera, a quantitative Western blot assay was developed. Q10 was the only class I molecule detectable in mouse sera. It occurs as a high m.w. complex of 200,000 to 300,000. The amount of Q10 in serum varies among different mouse strains and is controlled by a region telomeric to H-2S. Mice of the f haplotype do not express Q10, but all other mice examined (20 strains) with inbred or wild-derived H-2 haplotypes do. The H-2 haplotypes rank according to their levels of Q10 as follows: z, s greater than k, b greater than d, q greater than f; and the actual values range from to 60 micrograms/ml to undetectable levels in serum. In some strains the levels are higher in males than in females. The levels increase with age and decrease during pregnancy but not during lactation. There is a dramatic decrease after the injection of irritants or syngeneic tumor transplantation, but allostimulation has no effect on Q10 levels. The possible significance of this soluble class I molecule is discussed in the light of our findings. |
