We have previously demonstrated that two wild-derived stocks of mice, Idaho and Majuro, are significantly longer-lived than mice of a control stock (DC) generated as a four-way cross of commonly used laboratory strains of mice. This study provides independent confirmation of this earlier finding, as well as examining serum glucose, insulin, leptin, glycated hemoglobin (GHb), cataract severity, and glucose tolerance levels in each of the stocks. Both the mean (+20%) and maximum (+13%) life span of the Idaho mice were significantly increased relative to the DC stock, while in the Majuro mice only maximum (+15%) life span was significantly increased. In addition, Majuro mice were hyperglycemic in both the fed and fasted states compared both to laboratory-derived and Idaho stocks, had significantly elevated GHb levels and cataract scores, and were glucose intolerant although serum insulin levels did not differ between stocks. Body weight and body mass index (BMI)-corrected leptin levels were also dramatically (1.5-3-fold) higher in the Majuro mice. The longevity of Id mice was not accompanied by changes in serum glucose and insulin levels, or glucose tolerance compared to DC controls, although GHb levels were significantly lower in the Idaho mice. Taken together, these findings suggest that neither a reduction of blood glucose levels nor an increase in glucose tolerance is necessary for life span extension in mice.
