Proteintech plasma fgf21 concentrations

Fig. 3. Effect of FGH21 addition on GH signaling. A, B) Immunoblotting of JAK2, p-JAK2, STAT5b, and HSP90. Fao cells were cultured in the Full or Zero medium with 0–10 [5] pM of recombinant <t>FGF21</t> for 24 h. Cells were then treated with 100 nM GH or vehicle for 10 min. C) Igf1 mRNA levels were quantified using real-time qPCR. Values were normalized against the Actb mRNA level. Fao cells were cultured in the full medium with or without 100 nM GH and 0–105 pM of FGF21 for 24 h. Total RNA was isolated. Bar: means ± SEM (n = 3), *p < 0.05. (D) The expression of α-klotho (Kl), β-klotho (Klb), and FGF Receptor (Fgfr) 1–4 in Fao cells, rat primary hepatocytes, and rat tissue samples were analyzed using reverse transcription-PCR. (E) Immnoblotting of Erk and p-Erk. Fao cells were cultured in the full medium for 24 h. The cells were then treated with 0–104 pM of FGF21 or vehicle for 10 min.

Fig. 1. Eﬀect of aging and calorie restriction (CR) on plasma FGF21 concentration and Fgf21 expression in epididymal white adipose tissue (eWAT), liver, and soleus muscle (SOL) of Wistar rats. Total RNA was extracted from eWAT, liver, and SOL of AL-fed rats at 3.5 months of age. The mRNA expression of Fgf21 was quantiﬁed using RT-qPCR (n = 5–6). Tbp was used as a reference gene and to normalize the expression of the target gene (A). Total protein was extracted from eWAT, liver, and SOL of AL-fed rats at 3.5 months of age and quantiﬁed by western blotting, using anti-FGF21 and LMNB1 antibodies (B, upper panel). LMNB1 was used as a reference protein and to normalize target protein expression. The quantitative data (n = 3) are shown in B, lower panel. Plasma was collected from the four groups (AL-fed, AL-fasted, CR-fed and CR-fasted) of rats at 3.5, 9, and 24 months of age. FGF21 plasma concentration was measured by ELISA (n = 5–6) (C). Total RNA was extracted from the liver and eWAT from the four groups (AL-fed, AL-fasted, CR-fed and CR-fasted) of rats at 3.5, 9, and 24 months of age.
