HISTOCHEMICAL CHARACTERIZATION OF ADENOSINE TRIPHOSPHATASES IN SKELETAL MUSCLE FIBERS BY SELECTIVE EXTRACTION PROCEDURES

, 1973
Selective extraction procedures have been applied to frozen sections of rat skeletal muscles to determine the relative contribution of myosin adenosine triphosphatase (ATPase) and of membrane-bound (mitochondrial and sarcotubular) ATPases to the ...

Differential regulation of mTORC1 by leucine and glutamine [PDF]

, 2015
The mechanistic target of rapamycin (mTOR) complex 1 (mTORC1) integrates environmental and intracellular signals to regulate cell growth. Amino acids stimulate mTORC1 activation at the lysosome in a manner thought to be dependent on the Rag small ...

Pathological Roles of Astrocytes in Traumatic Brain Injury

CNS Neuroscience &Therapeutics, Volume 32, Issue 4, April 2026.
TBI induces intrinsic astrocytic changes, including reactive astrogliosis, A1 and A2 polarization, ion channels activation, pathological edema, oxidative stress, and metabolic dysregulation. These injury‐responsive astrocytes regulate neuroinflammation and tissue remodeling through dynamic crosstalk with microglia, macrophages, vascular endothelial ...

Carnitine modulates crucial myocardial adenosine triphosphatases and acetylcholinesterase enzyme activities in choline-deprived rats

, 2014
Choline is an essential nutrient, and choline deficiency has been associated with cardiovascular morbidity. Choline is also the precursor of acetylcholine (cholinergic component of the heart's autonomic nervous system), whose levels are regulated by

Chemotherapeutic efficacy of curcumin against plasma and cardio-hepatorenal electrolyte disruption in dichlorvos-challenged rats via augmentation of Na⁺/K⁺-ATPase and Ca²⁺/Mg²⁺-ATPase activities

Journal of Trace Elements and Minerals
Background: Dichlorvos (2,2-dichlorovinyl dimethyl phosphate or DDVP) is an effective organophosphate pesticide extensively employed in various pest management applications. However, it elicits cytotoxicity.

A Narrative Review of Antioxidant, Anti‐Inflammatory, Anti‐Apoptotic, Immunomodulatory, and Anticancer Properties of Rosa damascena Mill.

Food Science &Nutrition, Volume 14, Issue 4, April 2026.
Rosa damascena Mill. exhibits a broad spectrum of pharmacological activities mediated by its rich phytochemical profile. The plant enhances antioxidant defenses by increasing endogenous enzymes (CAT, SOD, GSH, GST, GPx, FRAP) and reducing oxidative stress markers (MDA, MPO).

RNA specificity and regulation of catalysis in the eukaryotic polynucleotide kinase clp1

, 2014
RNA-specific polynucleotide kinases of the Clp1 subfamily are key components of various RNA maturation pathways. However, the structural basis explaining their substrate specificity and the enzymatic mechanism is elusive.

The relationship between nerve terminal adenosine triphosphatases and neurotransmitter release:As determined by the use of antidepressant and other CNS-active drugs

, 1980
The role of adenosine triphosphatases (ATPases) in neurotransmitter release was studied using nerve terminals (synaptosomes) prepared from rat cerebral cortex as a model.

Molecular mechanisms of temperature adaptation in fish myofibrillar adenosine triphosphatases

, 1977
Studies have been carried out on the Mg2+ Ca2+-myofibrillar ATPase from the muscles of fish adapted to different environmental temperatures. The thermal stability of the ATPase is strongly correlated with mean habitat temperature. Activities of Antarctic
