Isoform localization of the creatine kinase in Ehrlich tumour cells

, 1999
Creatine kinase is considered a key enzyme for the intracellular transport and storage of high energy phosphate in muscle, brain and heart, through the postulated creatin-creatine phosphate shuttle patway.

Canine myocardial creatine kinase isoenzyme response to coronary artery occlusion

, 1989
The response of the myocardial creatine kinase system to acute coronary artery occlusion is not well defined. In the present study, we measured serial changes in myocardial creatine kinase and creatine kinase-MB activities after acute occlusion of the ...

Extracellular Vesicle Packaged TDP43 Derived From ECs Exacerbates Cigarette Tar‐Related Atherosclerosis Progression via Enhancing Macrophage Extracellular Traps

Advanced Science, EarlyView.
Cigarette tar triggers EC‐derived EVs carrying TDP43, which binds VDAC1 to boost MAMs, mitochondrial Ca2+ overload, and METs formation in macrophages, accelerating smoking‐related AS progression, while retinoic acid binds TDP43 to block this pathogenic cascade.

SLC6A8-mediated creatine uptake suppresses ERK2-FSP1 signaling and induces ferroptosis in colorectal cancer

Cell Reports
Summary: Tumor metabolic reprogramming is critical for providing energy to support proliferation and resistance to stress-induced cell death. However, the regulatory mechanisms linking these processes remain incompletely understood.

NCLX Inhibition plus Ca2+ Delivery Potentiates Electroporation and Antitumor Immunity in Pancreatic Ductal Adenocarcinoma

Advanced Science, EarlyView.
Electroporation combined with NCLX inhibition and Ca2+ delivery induces mitochondrial Ca2+ overload in PDAC cells, triggering pyroptosis, DAMP release, and antitumor immune activation. Simultaneously, suppression of tumor‐derived SPP1 weakens SPP1–CD44 signaling and remodels macrophages toward an antitumor phenotype, thereby enhancing CD8+ T‐cell ...

The effect of estrogen on muscle damage biomarkers following prolonged aerobic exercise in eumenorrheic women

Biology of Sport, 2015
This study assessed the influence of estrogen (E 2 ) on muscle damage biomarkers [skeletal muscle - creatine kinase (CK); cardiac muscle - CK-MB] responses to prolonged aerobic exercise.

BRCA1 Mutation‐Recognizing Tetrahedral Framework Nucleic Acid Nanoplatform Enables Coordinated PARP/WEE1 Inhibition and STING‐Associated Antitumor Immunity in Ovarian Cancer

Advanced Science, EarlyView.
BRCA1 mutation‐responsive FBOA‐tFNA selectively recognizes mutant transcripts and coordinates reduction‐responsive intracellular delivery of olaparib and adavosertib, amplifying DNA damage and weakening G2/M checkpoint protection. These effects are accompanied by STING‐associated immune activation and stronger antitumor immunity, while sequential anti ...

Increased postictal creatine kinase in epilepsy patients

Эпилепсия и пароксизмальные состояния
Excessive muscle activity during generalized convulsive seizures in epilepsy patients in some cases can cause significant changes in blood plasma biochemical parameters, increased level of a set of metabolites, particularly, serum creatine kinase ...

Dermatomyositis without creatine kinase elevation. A poor prognostic sign [PDF]

, 1986
Serum muscle enzyme levels are usually elevated in patients with untreated polymyositis and dermatomyositis. Creatine kinase is the muscle enzyme most often used to diagnose inflammatory myopathies. Seven patients with dermatomyositis and normal creatine

Ischemic Postconditioning Protects Aged Myocardium Against Ischemia/Reperfusion Injury by Regulating Mitochondrial Dynamics via piR‐4913

Advanced Science, EarlyView.
A tiny RNA tips the scales of cardiac injury in aging. piR‐4913 recruits OGT to Drp1 and drives its O‐GlcNAcylation at Thr604, promoting excessive mitochondrial fission that aggravates ischemia‐reperfusion injury. Ischemic postconditioning silences this pathway to restore mitochondrial balance and protect the aged myocardium, revealing piR‐4913 as a ...
