However, no intergroup disparity in survival time was observed in these 2 groups.​ As a positive control, the incidence rate (83%) and mortality rate (33%) of AAA in Dkk3+/+Apoe−/− mice transplanted with Dkk3+/+Apoe−/− bone marrow (BMT Apoe−/−→Apoe−/−) were much higher than those in the negative control group of Dkk3−/−Apoe−/− mice transplanted with Dkk3−/−Apoe−/− bone marrow (BMT DKO→DKO), which exhibited the lowest incidence rate (33%) without rupture (Fig. S7D to F). This evidence concerns the gene DKK3 and triple-A syndrome.
