Western blotting validation of SIRT2 expression and its correlation with the phosphorylation of p38MAPK. A Representative western blot analysis of SIRT2, p-p38MAPK, and GAPDH as loading controls. B Relative SIRT2 protein expression was normalized to GAPDH. HC, healthy controls, n = 5; PsO, n = 8; PsA, n = 8. Data was expressed mean ± SD. *, P < 0.05; **, P < 0.01; ***, P < 0.001. C The correlation between SIRT2 and p-p38MAPK was shown in all 21 samples
