Expression of KCa2.1, KCa2.2 and KCa2.3 in the atrial tissue of control rats and GK rats with or without metformin treatment. a Representative Western blots and b relative levels of KCa2.1, KCa2.2 and KCa2.3 in the atrial tissues of three groups of rats (n = 3 per group). c Relative levels of KCNN1, KCNN2 and KCNN3 mRNAs in the atrial tissues of three groups of rats (n = 8 per group). Non-normal distributed data were represented as median with interquartile range; ** represents P < 0.01 vs Con; # represents P < 0.05 vs GK; # # represents P < 0.01 vs GK
