GRK5-mediated exacerbation of pathological cardiac hypertrophy involves facilitation of nuclear NFAT activity.
RATIONALE G protein-coupled receptor kinases (GRKs) acting in the cardiomyocyte regulate important signaling events that control cardiac function. Both GRK2 and GRK5, the predominant GRKs expressed in the heart, have been shown to be upregulated in failing human myocardium. Although the canonical role of GRKs is to desensitize G protein-coupled receptors via phosphorylation, it has been demonst...
متن کاملInteraction between NFκB and NFAT coordinates cardiac hypertrophy and pathological remodeling.
RATIONALE Both nuclear factors of activated T cells (NFAT) and nuclear factor-κB (NFκB) are Rel homology domain (RHD)-containing transcription factors whose independent activities are critically involved in regulating cardiac hypertrophy and failure. OBJECTIVE To determine the potential functional interaction between NFAT and NFκB signaling pathways in cardiomyocytes and its role in cardiac h...
متن کاملCalcineurin/NFAT coupling participates in pathological, but not physiological, cardiac hypertrophy.
Calcineurin (PP2B) is a calcium/calmodulin-activated, serine-threonine phosphatase that transmits signals to the nucleus through the dephosphorylation and translocation of nuclear factor of activated T cell (NFAT) transcription factors. Whereas calcineurin-NFAT signaling has been implicated in regulating the hypertrophic growth of the myocardium, considerable controversy persists as to its role...
متن کاملIntegrative Physiology Interaction Between NF B and NFAT Coordinates Cardiac Hypertrophy and Pathological Remodeling
Rationale: Both nuclear factors of activated T cells (NFAT) and nuclear factorB (NF B) are Rel homology domain (RHD)-containing transcription factors whose independent activities are critically involved in regulating cardiac hypertrophy and failure. Objective: To determine the potential functional interaction between NFAT and NF B signaling pathways in cardiomyocytes and its role in cardiac hyp...
