NF-κB p65 protein expression was quantified using western blot in brain
hypothalamic nuclear and cytosolic fractions from wild-type (WT) and B1R
knockout (B1RKO) mice following a 3-week DOCA-salt, or sham treatment. Protein
expression was normalized to housekeeping genes Lamin (nuclear proteins) and
tubulin (cytosolic proteins). NF-κB p65 levels were significantly
increased in nuclear fractions (A) and decreased in cytosolic
fractions (B) in hypertensive DOCA-salt-treated mice, indicating
activation and translocation of NF-κB into the nucleus. However, no
change in NF-κB p65 expression was observed in B1RKO mice with DOCA-salt
compared to sham, suggesting that B1R gene deletion prevented NF-κB
activation. Data are presented as mean ±SEM. n=6/group. Two-way
ANOVA, *P<0.05 vs. WT+Sham,
†P<0.05 vs.
WT+DOCA.
