Open AccessNicotinamide Riboside, an NAD + Precursor, Protects Against Cardiac Mitochondrial Dysfunction in Fetal Guinea Pigs Exposed to Gestational Hypoxia
Gestational hypoxia inhibits mitochondrial function in the fetal heart and placenta contributing to fetal growth restriction and organ dysfunction. NAD + deficiency may contribute to a metabolic deficit by inh...

Open AccessEffects of Gestational Hypoxia on PGC1α and Mitochondrial Acetylation in Fetal Guinea Pig Hearts
Chronic intrauterine hypoxia is a significant pregnancy complication impacting fetal heart growth, metabolism, and mitochondrial function, contributing to cardiovascular programming of the offspring. PGC1α (pe...

Sex-Selective Increase of IGF-2 Expression in the Hypoxic Guinea Pig Placenta of Growth-Restricted Fetuses
Chronic hypoxia can cause fetal growth restriction (FGR) through placental dysfunction. Insulin-like growth factors (IGFs), such as IGF-2, play a major role in preservation of placental growth and function. We...

Chronic Hypoxia Inhibits Respiratory Complex IV Activity and Disrupts Mitochondrial Dynamics in the Fetal Guinea Pig Forebrain
Mitochondrial dysfunction is an underlying cause of childhood neurological disease secondary to the crucial role of mitochondria in proper neurodevelopment. We hypothesized that chronic intrauterine hypoxia (H...

Differential Responses of Hippocampal Neurons and Astrocytes to Nicotine and Hypoxia in the Fetal Guinea Pig
In utero exposure to cigarette smoke has severe consequences for the develo** fetus, including increased risk of birth complications and behavioral and learning disabilities later in life. Evidence from anim...

Chronic Hypoxia Impairs Cytochrome Oxidase Activity Via Oxidative Stress in Selected Fetal Guinea Pig Organs
We hypothesized that chronic hypoxia disrupts mitochondrial function via oxidative stress in fetal organs. Pregnant guinea pig sows were exposed to either normoxia or hypoxia (10.5% O2, 14 days) in the presence o...

Chronic hypoxia increases peroxynitrite, MMP9 expression, and collagen accumulation in fetal guinea pig hearts
Chronic hypoxia increases the expression of inducible nitric oxide synthase (iNOS) mRNA and protein levels in fetal guinea pig heart ventricles. Excessive generation of nitric oxide (NO) can induce nitrosative...

Acetylcholine Relaxation of Renal Artery and Nitric Oxide Synthase Activity of Renal Cortex Increase with Fetal and Postnatal Age
Endothelium-derived nitric oxide (NO) regulates hemodynamics in the fetal kidney and modulates renal perfusion during postnatal maturation. We hypothesize that NO release by renal arteries increases with fetal...
