Figure 8

Western blots of AT1R and AT2R. (a) Representative western blots of AT1R and AT2R. (b) The expression of AT1R gradually increased in the 12 M group and 24 M group compared with the 2 M group. (c) The expression of AT2R showed a tendency of decrease in the 24 M group compared with the 2 M group, but it was not statistically significant. (d) The ratio of AT1R to AT2R significantly increased in the 24 M group compared to 2 M and 12 M groups. ; . Values are shown as mean ± SD.
