Metabolic stimulation improves bioenergetics and haematologic indices of circulating erythrocytes from sickle cell mice

The Journal of Physiology, EarlyView.
Abstract figure legend Metabolic stimulation improves bioenergetics, redox state, hydration and hematologic indices of circulating erythrocytes from sickle cell mice. Retained mitochondria in circulating RBCs from sickle mice are a source of RBC ATP as mitochondria function (ETC, electron transport chain) inhibitors [rotenone, a mitochondrial complex I

Placental mitochondrial metabolic adaptation maintains cellular energy balance in pregnancy complicated by gestational hypoxia

The Journal of Physiology, EarlyView.
Abstract figure legend Placental mitochondrial adaptation to gestational hypoxia. Hypoxic pregnancy in sheep increases placental insulin like growth factor 2 (IGF2) signalling (1), which is associated with a shift in capacity away from β‐oxidation (2) and complex I‐mediated respiration (3), while maintaining total oxidative phosphorylation capacity (4).

CHARACTERIZATION OF CYTOCHROME P-450 MIXED FUNCTION OXIDASE OF RAT COLON MUCOSA

, 1983
Non-pregnant, female adult rats pretreated with either phenobarbital (PB) or (beta)-naphthoflavone ((beta)NF) through short-course intraperitoneal injections were shown by sodium dithionite-reduced carbon monoxide difference spectroscopy and NADPH ...

Induction of brain cytochrome P-450IIE1 by chronic ethanol treatment

, 1993
Cytochrome P-450 mediated metabolism is potentially involved in the expression of the pharmacological and/or toxicological effects of a wide variety of drugs and environmental chemicals upon tissues which contain this metabolic system.

Mitochondrial physiology in cardiac muscle of deer mice native to high altitude

The Journal of Physiology, EarlyView.
Abstract figure legend High‐altitude deer mice exhibited evolved changes in mitochondrial energy metabolism and reactive oxygen species (ROS) management that may support cardiac performance under cold hypoxic conditions. High‐altitude mice had increased activity of lactate dehydrogenase (LDH) in the heart, probably enhancing the capacity for lactate ...

NADPH-CYTOCHROME P-450 REDUCTASE: EVIDENCE FOR TWO SEPARATE STRUCTURAL DOMAINS AND ISOLATION AND CHARACTERIZATION OF THE MEMBRANE ASSOCIATED SEGMENT

, 1980
Homogenous detergent-solubilized NADPH-Cytochrome P-450 reductase was incorporated into microsomes and liposomes. This binding occurred spontaneously at temperatures between 4(DEGREES) and 37(DEGREES) and appeared to involve hydrophobic forces as the ...

α7nAChR agonist GTS‐21 ameliorates sepsis‐induced acute kidney injury via MEF2/PGC‐1α/HO‐1 axis in mice

Clinical and Translational Medicine, Volume 16, Issue 7, July 2026.
This diagram illustrates opposing pathways regulating AKI (acute kidney injury). The left pathway shows LPS/TLR4 triggering mitochondrial damage (low MMP, Cyt C release, ROS) leading to apoptosis. The right pathway shows α7nAChR agonists activating MEF2 to upregulate PGC‐1α/HO‐1, promoting mitochondrial biogenesis and inhibiting injury, highlighting ...

Recombinant mouse cytochromes P1-450 and P3-450: enzymatic characterization of the hemoprotein expressed in human cells infected with recombinant vaccinia virus.

, 1993
We expressed mouse cytochrome P1-450 and P3-450 using recombinant vaccinia virus gene expression system in HeLa cells that were devoid of significant basal levels of P-450.

Curcumin Attenuates Aroclor 1254‐Induced Oxidative, Genotoxic, and Apoptotic Alterations in HepG2 Cells

Journal of Biochemical and Molecular Toxicology, Volume 40, Issue 7, July 2026.
In HepG2 cells, Aroclor 1254 induced oxidative stress, DNA damage, apoptosis, and mutagenicity; co‐treatment with curcumin restored antioxidant defenses (GSH/thiols; SOD, CAT, GPx, GR, TrxR), reduced ROS and comet/8‐OHdG readouts, and attenuated caspase activation, demonstrating curcumin's hepatoprotective and genoprotective modulation of PCB toxicity.
