Effects of Bach1 deficiency on life span. (a) 52 wild-type and 53 Bach1-deficient mice were monitored for their lives. The average life span was 846.1 ± 199.3 days and 867.5 ± 154.0 days, respectively. (b) The body weight of wild-type and Bach1-deficient mice is plotted against the age. (c) The histology of kidney, spleen, skin of ear, and small intestine in wild-type and Bach1-deficient mice. Representative images are shown among three mice of each genotype. Scale bars are 100 μm. (d) The histology of liver in wild-type and Bach1-deficient mice. Representative images are shown among three mice of each genotype. Scale bars are 100 μm.
