RCAN1 can interact with IkappaBalpha and affect the phosphorylation of IkappaBalpha at tyrosine 42.
The sequence variations in RCAN1 promoter are not major genetic factors involved in sporadic CHD, at least in the current research population.
For DSCR1rs6517239, patients with an AA genotype had higher recurrence probability than patients carrying at least one allele G (37 +/- 4% SE vs. 15 +/- 6% SE) (HR: 0.51; 95% CI, 0.27-0.94; P = 0.027).
E4BP4 and BIM regulation correlated with that of RCAN1-1. A putative GRE and four EBPREs were identified within 1500bp upstream from the transcription start site of RCAN1-1
The transcriptional regulation of RCAN1.1 and RCAN1.4 by two alternative promoters, is reported.
Rcan1-1L may play a protective role in Ang II-treated cardiomyocytes through the induction of mitochondrial autophagy, and may be an alternative method of cardiac protection.
Results show that Rcan1 isoform 1L (Rcan1-1L) overexpression specifically activates mitophagy and increases cell survival under hypoxic conditions.
Regulator of Calcineurin 1 (RCAN1), a feedback inhibitor of the calcium-activated protein phosphatase calcineurin (CN), acts to suppress two distinctly different mechanisms of non-shivering thermogenesis.
Our results suggest that Rcan1 might act as endogenous negative modulator of COX-2 expression and activity by inhibiting calcineurin and NF-kB pathways to maintain normal contractility and vascular stiffness in aorta and small mesenteric arteries, respectively.
This study demonstrated that Rcan1 is regulated by oxidative stress and identified RCAN1 as a potential diagnostic marker of acute pancreatitis.
Conditional deletion of Rcan1 predisposes to hypertension-mediated intramural hematoma and subsequent aneurysm and aortic rupture.
These findings demonstrate a novel regulatory role of RCAN1 in TLR signaling, which differentially regulates MyD88 and TRIF pathways.
The expression of DSCR1-4 increased strongly at P16 after OIR. There was no change in messenger RNA (mRNA) expression of DSCR1-1 at P16 after oxygen-induced retinopathy. The increased DSCR1 was mainly located in the RGCs of avascular retina. In addition, DSCR1-4 expression was increased in primary RGCs after hypoxia exposure.
RCANs play critical roles in bone homeostasis by regulating both osteoclastogenesis and osteoblastogenesis, and they serve as inhibitors for calcineurin-NFATc1 signaling both in vivo and in vitro.
The present study demonstrates that RCAN1 deficiency protects against Salmonella intestinal infection by enhancing proinflammatory JNK signaling.
DSCR1 as a key protein that couples axon growth.
from amongst the myriad of gene expression changes occurring in Type 2 diabetes (T2D) b-cells where we had little knowledge of which changes cause b-cell dysfunction, we applied a trisomy 21 screening approach which linked RCAN1 to b-cell mitochondrial dysfunction in T2D.
These results uncover a critical link between calcineurin signalling, impaired neurotrophin trafficking and neurodevelopmental deficits in the peripheral nervous system in Down syndrome.
Data suggest that expression of Dscr1 in hippocampus can be regulated by dietary factors; supplementation of maternal diet and offspring diet with fish oil down-regulates Dscr1 in hippocampus of offspring; Dscr1 is a presumed target in Down syndrome.
inhibition of the calcineurin-nuclear factor of activated T cells pathway enhances the proliferation of granulocyte-monocyte progenitors both in vitro and in vivo
PACAP targets RCAN1 to control neuronal differentiation.
We also confirmed that overexpression of RCAN1-1L could inhibit the transcriptional activation of an NFAT-dependent promoter in response to PMA and ionomycin by inhibiting Calcineurin activity in HEK293T cells
found that RCAN1/3 interact with RAF kinases and CN in a non-exclusive manner. Our data suggests that the balance of RCAN interactions with CN and/or RAF kinases may influence T cell positive selection
Calcineurin and its regulator, RCAN1, confer time-of-day changes in susceptibility of the heart to ischemia/reperfusion.
Data indicate that neuron from Down syndrome candidate region 1 (DSCR1)-transgenic mice were more resistant than wild-type neurons to apoptotic cell death following 24 h of glucose deprivation.
A major role for haematopoietic Rcan1 in atherosclerosis and suggest that therapies aimed at inhibiting RCAN1 expression or function might significantly reduce atherosclerosis burden.
RCAN1-regulated vascular branching which may play a role in the patterning of morphologically different vasculature.
The protein encoded by this gene interacts with calcineurin A and inhibits calcineurin-dependent signaling pathways, possibly affecting central nervous system development. This gene is located in the minimal candidate region for the Down syndrome phenotype, and is overexpressed in the brain of Down syndrome fetuses. Chronic overexpression of this gene may lead to neurofibrillary tangles such as those associated with Alzheimer disease. Three transcript variants encoding three different isoforms have been found for this gene.
