Figure 5. Effect of aging and CR on serum TG (n = 6 per group). Serum TG levels are increased in Old rats compared to those in Young rats and are decreased in Old-CR rats compared to those in Old rats (Young: 82.28 ± 7.111 mg/dL, Old: 106.8 ± 11.23 mg/dL, and Old-CR: 40.73 ± 3.689 mg/dL). Data are presented as mean ± SEM. Old-CR, old group under CR; TG, triglycerides.
