The role of FGF21 activated signalling pathways in cardioprotection.

Fig. 3A1: Cardiomyocytes treated with FGF21 (100 nM) for 5–30 minutes. Phosphorylated ERK1/2 [Fig. 3A1]; Akt [Fig. 3A2] and AMPK [Fig. 3A3] proteins are represented in relation to total proteins, expressed as fold increase over basal. ***P<0.001, **P<0.01, *P<0.05 vs. basal, n = 6 per group. Fig. 3B1: RPP with ischemia/reperfusion and FGF21 treatment following pre-incubation with inhibitors (TO-901317; wortmanin; Compound C or U0126) aP<0.05, bP<0.01 vs. FGF21 only treatment, n = 6 per group. Fig. 3B2: Infarcted area (%) following ischemia/reperfusion and FGF21 treatment following pre-incubation with inhibitors (TO-901317; wortmanin; Compound C or U0126) **P<0.01, *P<0.05 vs. FGF21 treated, n = 6 per group.
