Age-dependent effects of RIPC plasma on GSK3β phosphorylation. Representative western blot analysis experiments and summarized data of GSK3β phosphorylation (Ser9) in heart tissue samples of young male rats after application of control (Con) and RIPC plasma of young (a) and aged volunteers (b). Summarized data presenting AVI (arbitrary units of average light intensity) are shown. Data are presented as mean ± SD, n = 10 for all groups. *P < 0.05 vs. Con (t-test comparison)
