A mouse model of type 1 diabetes with concomitant activation of Nrf2
signaling activation. (A) Keap1FA/+
mice were backcrossed with NOD/Shi background mice for 8 generations (N8). The
mice were mated to obtain
NOD::Keap1+/+,
NOD::Keap1FA/+ and
NOD::Keap1FA/FA genotype mice.
The NOD::Keap1+/+ and
NOD::Keap1FA/FA mice were
examined for eight successive generations (N8) as indicated. (B)
Nqo1 mRNA expression levels in the spleens of the
NOD::Keap1+/+
(n=5),
NOD::Keap1FA/+
(n=4) and
NOD::Keap1FA/FA mice
(n=6). The data were normalized to
β-actin, and the expression levels in the
NOD::Keap1+/+ mice were set as
1. (C) The Keap1FA/FA and
Keap1+/– mice were
backcrossed with NOD/Shi background mice for 12 and 11 generations (N12 and
N11), respectively. The
NOD::Keap1FA/FA mice and
NOD::Keap1+/– mice were
mated, and NOD::Keap1FA/–
and NOD::Keap1FA/+ mice were
generated as indicated. (D) Nqo1 mRNA expression levels in the
spleens of the NOD::Keap1FA/+
(n=14) and
NOD::Keap1FA/–
(n=13) mice. The data were normalized to
β-actin, and the expression levels
in the NOD::Keap1FA/+ mice were set
as 1. The bar represents the median. ANOVA followed by Fisher’s LSD post
hoc test for (B) and Student’s t-test for (D) were
applied. *P<0.05, **P<0.01 and
***P<0.001.
