Fig. 5From: Metformin regulates atrial SK2 and SK3 expression through inhibiting the PKC/ERK signaling pathway in type 2 diabetic ratsA proposed pathway for the protective effects of metformin against DM-induced disorders on atrial SK2 and SK3 channels. DM induces an excessive activitiy of PKC which is followed by a sequential activation of ERK and causes disorders of atrial SK2 and SK3 channels. Metformin treatment leads to a sequential inhibition on the activities of PKC and ERK and results in an improvement on the disordersBack to article page
