Figure 6

(A) Recorded oxygen (O2) profile: Recorded O2 profile alternating between 10% and 21% every 5 min under chronic intermittent hypoxia condition in the chamber of an in vivo study. (B) Kidney tissue NE levels after RD: RD(−) mice show significantly higher kidney tissue NE levels compared with RD(+) mice. Kidney tissue NE levels of mice subjected to RD are almost undetectable. **P < 0.01 [RD(−) + CIH vs. RD(+) +CIH]. (C) Protocol: We divided the mice into three groups: (1) Control in %O2 21% (n = 21), (2) CIH (n = 22), and (3) RD/CIH (n = 13).
