Sirt1 expression in the extra-renal tissues after consumption of a calorie restriction (CR), high-salt (HiS), or low-salt (LoS) diet for 7 days.

Representative immunoblots for Sirt1 in the heart, muscle, brain, and fat tissue from rats after consuming the 7-day CR, HiS, or LoS diets are shown. The CR and LoS diets significantly increased Sirt1 expression in all tissues, whereas the HiS diet did not change the level of Sirt1 expression. ^aP = 0.005, ^bP = 0.004, ^cP = 0.050, ^dP = 0.026, ^eP = 0.041, ^fP = 0.023, ^gP = 0.041, ^hP = 0.054 vs. the control group. N = 6 in each group.
