An adenylate kinase gene from a member of the archaebacterial kingdom, the thermoacidophilic archaebacterium (archaeon) Sulfolobus acidocaldarius, has been cloned and sequenced for the first time. Two degenerate oligonucleotide probes, based on the N-terminal amino acid sequence information, led to
The long isoform of eukaryotic adenylate kinase has a dual subcellular location in the cytoplasm and in the mitochondrial intermembrane space. Protein sequences and modifications are identical in both locations. In yeast, the bulk of the major form of adenylate kinase (Aky2p) is in the cytoplasm
Antibodies against adenylate kinase 5 (AK5) have been described in patients with non-paraneoplastic limbic encephalitis, mainly in men around 70 years of age. Routine testing with specific cell-based assays is not yet available. Three patients with episodic anterograde memory problems and depression
Sarcopenia is the drastic loss of skeletal muscle mass and strength during ageing. In order to better understand the molecular pathogenesis of age-related muscle wasting, we have performed a DIGE analysis of young adult versus old rat skeletal muscle. Proteomic profiling revealed that out of 2493
Adenylate kinase (AK) was determined in a lumbo-cisternal cerebrospinal fluid (CSF) gradient and in CSF from patients with mental deterioration. AK activity was unchanged in the gradient and different from albumin and albumin ratio (alb CSF/albumin serum), a blood-brain barrier marker in the same
Abnormally hyperphosphorylated tau is often caused by tau kinases, such as GSK3β and Cdk5. Such occurrence leads to neurofibrillary tangle formation and neuronal degeneration in tauopathy, including Alzheimer's disease (AD). However, little is known about the signaling cascade underlying the
To report 10 patients with limbic encephalitis (LE) and adenylate kinase 5 autoantibodies (AK5-Abs).
We conducted a retrospective study in a cohort of 50 patients with LE with uncharacterized autoantibodies and identified a specific target using immunohistochemistry, Western blotting,
Oxidative stress plays a pivotal role in normal brain aging and various neurodegenerative diseases, including Alzheimer's disease (AD). Irreversible protein carbonylation, a widely used marker for oxidative stress, rises during aging. The temporal cortex is essential for learning and memory and
Obesity-related diseases such as the metabolic syndrome and type 2 diabetes originate, in part, from the progressive metabolic deterioration of skeletal muscle. A preliminary proteomic survey of rectus abdominus muscle detected a statistically significant increase in adenylate kinase (AK)1,
During the fifty years since hypotensive anaesthesia, induced hypotension to minimise intraoperative blood loss, became an established routine, there have been few reports of associated cerebral complications. However, evidence of disturbed cerebral function among patients undergoing orthognathic
Interpretation of biochemical measurements in the human brain after death is complicated by a variety of premortem, perimortem, and postmortem factors. The activity of glutamic acid decarboxylase (GAD) in particular has been found to vary considerably among human brains. In contrast to
Great importance is attached to structural and functional deterioration of mitochondria as a reason for ageing of an organism; the attention of many scientists has been concentrated on such questions as age changes in the system of oxidative phosphorylation, damage of mitochondrial DNA by free
BACKGROUND
Heart muscle primarily relies on adenosine triphosphate produced by oxidative phosphorylation and is highly vulnerable to anoxic insult. Although a number of strategies aimed at improving myopreservation are available, no effective means of preserving mitochondrial energetics under
A conserved domain of the secY genes from Bacillus subtilis, Mycoplasma capricolum and Escherichia coli was used to design degenerate oligodeoxyribonucleotides. These synthetic DNA sequences were used to screen a lambda library of Brevibacterium flavum MJ233. A 1.5-kb KpnI fragment of a recombinant
Progressive x-linked muscular dystrophy represents the most commonly inherited neuromuscular disorder in humans. Although the disintegration of the dystrophin-associated glycoprotein complex triggers the initial pathogenesis of Duchenne muscular dystrophy, secondary alterations in metabolic
