Kv4 channels are differentially expressed across the mouse left ventricular free wall. Accordingly, the transient outward K+ current (Ito), which is produced by Kv4 channels, is greater in left ventricular epicardial (EPI) than in endocardial (ENDO) cells. However, the mechanisms underlying heterogeneous Kv4 expression in the heart are unclear. Here, we tested the hypothesis that differential [...
Pluripotency-associated transcription factor Foxd3 is required for maintaining pluripotent cells. However, molecular mechanisms underlying its function are largely unknown. Here, we report that Foxd3 suppresses differentiation induced by calcineurin–NFAT signaling to maintain the ESC identity. Mechanistically, Foxd3 interacts with NFAT proteins and recruits co-repressor Tle4, a member of the Tl...

Nuclear factors of activated T cells (NFATs) are Ca(2+)-sensitive transcription factors that have been implicated in hypertrophy, heart failure (HF), and arrhythmias. Cytosolic NFAT is activated by dephosphorylation by the Ca(2+)-sensitive phosphatase calcineurin, resulting in translocation to the nucleus, which is opposed by kinase activity, rephosphorylation, and nuclear export. Four differen...
Jabr RI, Wilson AJ, Riddervold MH, Jenkins AH, Perrino BA, Clapp LH. Nuclear translocation of calcineurin A but not calcineurin A by platelet-derived growth factor in rat aortic smooth muscle. Am J Physiol Cell Physiol 292: C2213–C2225, 2007. First published February 15, 2007; doi:10.1152/ajpcell.00139.2005.—Calcineurin regulates the proliferation of many cell types through activation of the nu...
Skeletal muscle development and growth are regulated through multiple signaling pathways that include insulin-like growth factor I (IGF-I) and calcineurin activation of nuclear factor of activated T cell (NFAT) transcription factors. The developmental regulation and molecular mechanisms that control IGF-I gene expression in murine embryos and in differentiating C2C12 skeletal myocytes were exam...
Pathological cardiac hypertrophy induced by adrenergic overactivation can subsequently develop to heart failure which remains as a leading cause of mortality worldwide. Tanshinone IIA is a lipid-soluble pharmacologically active compound extracted from the rhizome of the Chinese herb Salvia miltiorrhiza, a well-known traditional Chinese medicine used for the treatment of cardiovascular disorders...
Tacrolimus (FK506) is an immunosuppressive drug that binds to the immunophilin FKBPB12. The FK506-FKBP12 complex associates with calcineurin and inhibits its phosphatase activity, resulting in inhibition of nuclear translocation of nuclear factor of activated T-cells (NFAT). There is increasing data supporting a critical role of NFAT in mediating angiogenic responses stimulated by both vascular...
OBJECTIVE Hyperglycemia is a recognized risk factor for cardiovascular disease in diabetes. Recently, we reported that high glucose activates the Ca(2+)/calcineurin-dependent transcription factor nuclear factor of activated T cells (NFAT) in arteries ex vivo. Here, we sought to determine whether hyperglycemia activates NFAT in vivo and whether this leads to vascular complications. METHODS AND...
The calcineurin/NFAT signaling pathway has been found to play a role in regulating growth and differentiation in several cell types. However, the functional significance of NFAT in the vasculature is largely unclear. Here we show that NFATc1, NFATc3 and NFATc4 are expressed in human myometrial arteries. Confocal immunofluorescence and western blot analysis revealed that endothelin-1 efficiently...
