TTS-miRs reduce apical adrenergic sensitivity and increase basal maximum adrenergic response. TTS-miR adrenaline concentration-response curves in apical/basal cardiomyocytes. (A/B) FS in apex/base. (C/D) Normalisedresponse in apex/base. (E/F) FS in apex/base with TTS-miRs together. (G/H) Normalisedresponse in apex/base with TTS-miRs together. n/N = 6/6. Mean ± SEM shown, n’ = cardiomyocytes and ‘N’ = rats, significance by non-linear regression comparing agonist vs. response for A–H (F-test, Supplementary material online, Table S1).
