He warned that only 20% of the mice were long-term survivors so the vaccine would need further development.
Experimentation was performed under dim red light (<0.25 µW/cm2, >650 nm), and mice were long-term dark adapted (>12 hr) prior to recording.
We previously reported that Irs1 −/− mice were long-lived and had improved late-life health (Selman et al., 2008, 2011).
Although CR SIRT1+/− mice were long-lived, they displayed more frequent defects/pathologies (44% incidence), including eye infections or redness, and abnormal growth compared with CR SIRT1+/+ mice (31% incidence) (Table S6).
For instance, GHR knockout mice are long living despite having higher adiposity (Bonkowski et al, 2006).
This sexual dimorphism is also observed in mice, where rapamycin-mediated life span extension is smaller in males than in females (Harrison et al., 2009), and only female S6K1 mutant mice are long lived (Selman et al., 2009).
Thirty years later, his lab serendipitously discovered that the midget mice are long-lived.
Like RIIβ, AC is a component of the PKA signaling pathway, and like RIIβ−/− mice, AC5 null mice are long-lived, suggesting an association of the PKA pathway with cardiac protection and extended lifespan.
It was observed that female Irs1 -/- mice are long-lived.
Ames mice are long-lived (by 49% in men, and 68% in women).
Moreover, it was reported that bi-maternal mice are long-lived and, because Rasgrf1is an imprinted gene expressed from the paternal allele in neonates, it is possible that bi-maternal mice are long-lived due to Rasgrf1 effects [ 12- 13].
