Creatine kinase-catalyzed ATP-phosphocreatine exchange: Comparison of 31P-NMR saturation transfer technique and radioisotope tracer methods [PDF]

open access: yes, 1986
Unidirectional fluxes from ATP to phosphocreatine, catalyzed by the MM isoenzyme of creatine kinase, were measured by both the 31P-NMR saturation transfer technique and radioisotope tracer ([γ-32P]ATP) method.

Targeting eIF5A combats breast cancer progression by ClpP‐dependent mitochondrial oxidative stress

open access: yesInterdisciplinary Medicine, EarlyView.
This study identified the eIF5A‐ClpP axis as a key driver of breast cancer progression. Targeting eIF5A suppresses tumor growth by inducing ClpP‐dependent mitochondrial oxidative stress, revealing a novel therapeutic vulnerability. Abstract Breast cancer (BC) poses a persistent global health challenge, necessitating new therapeutic targets.

Phosphocreatine in Red and White Muscle

open access: yesExperimental Biology and Medicine, 1951
ConclusionThe creatine phosphate content of the white breast muscle of the fowl was found to be over twice as great as that of the red leg muscle. In the “flying” bird, the pigeon, the red breast muscle and the leg muscle contained approximately the same levels of this high energy phosphate.

Metabolomic insights for the authentication and traceability of antibiotic‐free pork: a pilot study

open access: yesJournal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Antibiotic‐free production within the meat supply chain is a source of concern since new voluntary label claims need to be authenticated to prevent fraud. Therefore, an untargeted 1H NMR‐based metabolomics approach coupled to unsupervised (principal component analysis) and supervised (orthogonal partial least squares discriminant ...

THE HYDROLYSIS OF PHOSPHOCREATINE AND THE ORIGIN OF URINARY CREATININE

open access: yesJournal of Biological Chemistry, 1947
Shaffer (1), Myers and Fine (2), and Hahn and Meyer (3) adduced evidence that muscle creatine is the precursor of urinary creatinine. This was questioned by Chanutin and Kinard (4) but was conclusively proved by Bloch, Schoenheimer, and Rittenberg (5, 6) by isotope tracer evidence, which also showed that creatinine was the only normal urinary ...

Improving Fetal Single‐Voxel Magnetic Resonance Spectroscopy With Spectral Registration

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To evaluate whether spectral registration improves spectral quality and quantification reliability in in vivo single‐voxel fetal brain MRS: Methods Fourteen fetal PRESS datasets were acquired at 3 T at TE = 35 ms and TE = 135 ms. Raw data were processed with eddy‐current phase correction, coil combination, spectral registration, and ...

Single and dual RPA‐CRISPR/Cas assays for point‐of‐need detection of Stewart's wilt pathogen (Pantoea stewartii subsp. stewartii) of corn and Maize dwarf mosaic virus

open access: yesPest Management Science, Volume 81, Issue 4, Page 1988-1999, April 2025.
Schematic diagram of the single and dual RPA‐CRISPR/Cas12a/13a diagnostic assays for the detection of Pantoea stewartii subsp. stewartii and Maize dwarf mosaic virus. The validated assays provide a useful and sensitive molecular tool for detecting two quarantine pathogens of maize within a minimal resource framework suitable for fast‐tracking the ...

Nongenomic effects of aldosterone on phosphocreatine levels in human calf muscle during recovery from exercise. [PDF]

open access: yes, 1996
Nongenomic in vitro effects of aldosterone on the sodium-proton antiport and intracellular second messengers have been described in human mononuclear leukocytes, vascular smooth muscle cells, and endothelial cells.

Analysis of creatine kinase activity with evaluation of protein expression under the effect of heat and hydrogen peroxide [PDF]

open access: yesThe Ukrainian Biochemical Journal, 2015
Protein oxidation has detrimental effects on the brain functioning, which involves inhibition of the crucial enzyme, brain type creatine kinase (CKBB), responsible for the CK/phosphocreatine shuttle system. Here we demonstrate a susceptibility of CKBB to

Brain viral reservoir seeding and neurological metabolic dysregulation in early‐life immunodeficiency virus infection

open access: yesBrain Pathology, EarlyView.
Brain viral reservoirs were undetectable in neonatal SIV during the first 3 days post infection; antiretroviral therapy (ART) at 3 dpi prevented brain reservoir seeding and normalized metabolic function, highlighting the necessity of very early treatment to protect the developing CNS.
