overexpression of SERCA2a by in vivo rAAV1-mediated intracoronary gene transfer preserved systolic function, potentially prevented diastolic dysfunction, and improved ventricular remodeling.
pulmonary artery banding decreased the expression of (Serca) 2a while expression of Na(+)/Ca(2+) exchanger-1 was significantly upregulated in the right but not in the left atria of rabbit hearts; pressure is the major trigger.
Crystal structure of Ca2+-ATPase from skeletal muscle sarcoplasmic reticulum is determined, which shows that a two-step rotation of the cytoplasmic A-domain opens and closes the luminal gate through the movements of the M1-M4 transmembrane helices.
Data show that rabbit cold tolerance is probably related to increased muscle oxidative metabolism and heat production by SERCA1 and that these changes are not completely dependent on normal thyroid function.
These results indicate a mechanism relating SERCA1 vicinal-cysteines oxidation to muscle fatigue.
for the in vivo study, BALB/c mice were treated with ATO and/or Sal A via daily tail vein injections for two weeks... Sal A increased sarcoplasmic reticulum (SR) Ca(2+)-ATPase (SERCA) activity and expression, alleviated [Ca(2+)]ER depletion, and decreased ER stress-related protein expression
These data demonstrate that the activity of RyR2, but not SERCA2a, is a major determinant of Ca2+ alternans in intact working mouse hearts.

Pin1 serves as a modulator of SERCA2a and Na(2+)/Ca(2+) exchanger 1 Ca(2+) handling proteins, with loss of function resulting in impaired cardiomyocyte relaxation.
Pep2.5 prevented the down-regulation of SERCA2 expression in a) murine heart samples obtained from mice with sepsis and b) in cardiomyocytes exposed to serum from septic shock patients. Thus, we speculate that Pep2.5 may be able to prevent down-regulation of cardiac SERCA2 expression in patients with sepsis.
The findings support a salutary role of TLR9 in some subsets of HF conditions and underline the importance for future studies on the mechanisms of TLR9 in diastolic HF.
Our results indicate that changes in cell shape changed nuclear morphology and then the gene expression of IP3R1 and SERCA2, which produced different intracellular calcium transient patterns.
Nevertheless, the functional role of protein serotonylation in controlling SAN automaticity is largely unexplored. In this study, we screened the cardiomyocytes proteins and found that sarco(endo)plasmic reticulum Ca ATPase type 2a (SERCA2a) can be serotonylated. Simulation studies using mathematical SAN cell model showed that variation of Ca(2+) affinity of SERCA2a pump cause either tachycardia or bradycardia.
Muscle RANK deletion had no significant effects on the sham or denervated slow-twitch soleus muscles. These data identify a novel role for RANK as a key regulator of Ca(2+)storage and SERCA activity, ultimately affecting denervated skeletal muscle function.
Generated were mice harboring N-ethyl-N-nitrosourea (ENU)-induced allelic mutations in Serca2: three missense mutations and one nonsense mutation. Mice harboring these Serca2 mutations developed tumors that were categorized as either early onset squamous cell tumors (SCT), with development similar to null-type knockout mice [2,4] (aggressive form; M682, M814), or late onset tumors (mild form; M1049, M1162).

These data reveal myofibrillar Ca(2+)-sensitivity to be an important determinant of the cardiac effects of SERCA2 haploinsufficiency and raise the possibility that Darier disease patients are more susceptible to heart failure under certain conditions.
SERCA2a gene transfer in the failing heart not only improves contractile function but also directly restores electric stability through amelioration of key arrhythmogenic substrate.
This gene encodes one of the SERCA Ca(2+)-ATPases, which are intracellular pumps located in the sarcoplasmic or endoplasmic reticula of muscle cells. This enzyme catalyzes the hydrolysis of ATP coupled with the translocation of calcium from the cytosol into the sarcoplasmic reticulum lumen, and is involved in regulation of the contraction/relaxation cycle. Mutations in this gene cause Darier-White disease, also known as keratosis follicularis, an autosomal dominant skin disorder characterized by loss of adhesion between epidermal cells and abnormal keratinization. Alternative splicing results in multiple transcript variants encoding different isoforms.
