Ca²⁺ handling protein expression in hearts of CIA and control mice. (A) Representative immunoblots of, ryanodine receptor 2 (RyR2), dihydropyridin receptor (DHPR), calsequestrin 2 (CSQ2), SERCA2a, phospholamban (PLN, pentameric and monomeric form) and housekeeping protein glyceraldehyde 3‐phosphate dehydrogenase (GAPDH). (B) Mean band densities normalized to GAPDH and the mean value in control hearts set to 1.0 (n = 6–8). Data are presented as box and whiskers min and max including all points. *p < 0.05, †p < 0.01, ‡p < 0.001 with unpaired t test. Data were analyzed with Mann–Whitney non‐parametric test.
