GSK3B and cardiac hypertrophy: It has been reported that development of cardiac hypertrophy may be involved in multiple signalling pathways such as the canonical G‐protein‐coupled receptors (GPCR) signalling pathway, the calcineurin–nuclear factor of activated T cells (NFAT) signalling pathway, the mitogen‐activated protein kinase (MAPK) signalling pathway and PI3K/Akt/GSK‐3β signalling pathway 3.
