The Ca(2+)/calmodulin-dependent phosphatase calcineurin plays a crucial role in gene expression in different cell types such as T-lymphocytes, cardiac myocytes, and smooth muscle cells. A possible role for calcineurin in gene expression was recently found in neurons, where calcineurin regulates the expression of several genes involved in Ca(2+) homeostasis. To detect additional genes regulated ...
Calcineurin, which functions in calcium signaling, is expressed in skeletal and cardiac muscle and has been linked to sensitivity to muscle strength training. It is also proposed to contribute to individual aerobic endurance. To investigate the relationship between calcineurin-encoding genes and aerobic endurance traits, 126 young-adult Han Chinese males were enrolled in an aerobic exercise tra...
In Saccharomyces cerevisiae, the Ca(2+)/calmodulin-dependent protein phosphatase, calcineurin, is activated by specific environmental conditions, including exposure to Ca(2+) and Na(+), and induces gene expression by regulating the Crz1p/Tcn1p transcription factor. We used DNA microarrays to perform a comprehensive analysis of calcineurin/Crz1p-dependent gene expression following addition of Ca...
Calcium signalling is important for differentiation-dependent gene expression, but is also involved in other cellular functions. Therefore, mechanisms must exist to distinguish calcium signalling relevant to differentiation. Calcineurin is a calcium-regulated phosphatase that is required for myogenic gene expression and skeletal muscle differentiation. Here, we demonstrate that inhibition of ca...
Nuclear factor of activated T-cells (NFAT) and calcineurin are essential regulators of immune cell and mesenchymal cell differentiation. Here we show that elevated intracellular calcium induces chondrogenesis through a calcineurin/NFAT signaling axis that activates bone morphogenetic protein (BMP) expression. The calcium ionophore, ionomycin, induced chondrogenesis through activation of calcine...
Aortic valve stenosis (AS) is a major health problem. Extensive myocardial remodeling increases operative risk and might lead to incomplete reverse with persistent symptoms after aortic replacement (AVR); this makes the optimal timing of AVR clinical challenge. The pathogenesis behind unclear. Central among signaling pathways in heart pro-hypertrophic Ca 2+ -activated calcineurin its downstream...
We examined whether calcineurin-NFAT (nuclear factors of activated T cells) signaling plays a role in specifically directing the expression of utrophin in the synaptic compartment of muscle fibers. Immunofluorescence experiments revealed the accumulation of components of the calcineurin-NFAT signaling cascade within the postsynaptic membrane domain of the neuromuscular junction. RT-PCR analysis...
The p53-induced gene-6 (proline oxidase) mediates apoptosis through a calcineurin-dependent pathway.
Proline oxidase is a p53-induced redox gene that can generate reactive oxygen species (ROS) and mediate apoptosis in tumor cells. We report that proline oxidase is a downstream effector in p53-mediated activation of the calcium/calmodulin-dependent phosphatase calcineurin in lung, renal, colon, and ovarian carcinoma cells. The activation of calcineurin by p53 and proline oxidase was detected by...
Calcineurin, a calcium/calmodulin-regulated protein phosphatase, modulates gene expression in cardiac and skeletal muscles during development and in remodeling responses such as cardiac hypertrophy that are evoked by environmental stresses or disease. Recently, we identified two genes encoding proteins (MCIP1 and MCIP2) that are enriched in striated muscles and that interact with calcineurin to...
The serine/threonine phosphatase calcineurin is an important regulator of calcium-activated intracellular responses in eukaryotic cells. In higher eukaryotes, calcium/calmodulin-mediated activation of calcineurin facilitates direct dephosphorylation and nuclear translocation of the transcription factor nuclear factor of activated T-cells (NFAT). Recently, controversy has surrounded the role of ...
