Cardiomyocyte transcription is controlled by combined MR and circadian clock signalling.

We previously identified a critical pathogenic role for MR activation in cardiomyocytes that included a potential interaction between the MR and the molecular circadian clock. While glucocorticoid regulation of the circadian clock is undisputed, MR interactions with circadian clock signalling are limited. We hypothesised that the MR influences cardiac circadian clock signalling, and vice versa.
