A physiological role for the receptor independent of xenobiotic ligand has been recognized in Ahr-null mice (Gonzalez and Fernandez-Salguero 1998), which show, among others, an impaired cardiovascular phenotype with retained fetal vascular structures in the liver and eye that fail to undergo apoptosis (Lahvis et al. 2005).

Note that only the 90-day WT tissue had the characteristic bands associated with Mgam but that smaller bands were recognized in all mice.
Although all pinwheel components could also be recognized in 2-m SAMP8 mice, the organization was altered (Fig. 1A, B).
Recombination mediated by the latter is recognized in crosses to R26R mice as clones of cells expressing βgal.
A similar pattern was recognized in published images of ARC kisspeptin staining of homozygous ArKO female mice [17] and also observed in Kiss1R−/− mice (data not shown).
Many members of the Northeast Rat and Mouse Club have come to believe that American-bred mice have their own fine points which ought to be recognized in a separate standard.
