1.
Primary myoblasts from intrauterine growth-restricted fetal sheep exhibit intrinsic dysfunction of proliferation and differentiation that coincides with enrichment of inflammatory cytokine signaling pathways
Posont R, Most M, Cadaret C, Marks-Nelson E, Beede K, Limesand S, et al.
J Anim Sci . 2022 Jul; 100(8). PMID: 35908792
Intrauterine growth restriction (IUGR) is linked to lifelong reductions in muscle mass due to intrinsic functional deficits in myoblasts, but the mechanisms underlying these deficits are not known. Our objective...
2.
Intermittent maternofetal oxygenation during late gestation improved birthweight, neonatal growth, body symmetry, and muscle metabolism in intrauterine growth-restricted lambs
Cadaret C, Posont R, Swanson R, Beard J, Gibbs R, Barnes T, et al.
J Anim Sci . 2021 Dec; 100(1). PMID: 34865027
In humans and animals, intrauterine growth restriction (IUGR) results from fetal programming responses to poor intrauterine conditions. Chronic fetal hypoxemia elevates circulating catecholamines, which reduces skeletal muscle β2 adrenoceptor content...
3.
Lipopolysaccharide endotoxin injections elevated salivary TNFα and corneal temperatures and induced dynamic changes in circulating leukocytes, inflammatory cytokines, and metabolic indicators in wether lambs
Cadaret C, Abebe M, Barnes T, Posont R, Yates D
J Anim Sci . 2021 Apr; 99(6). PMID: 33871612
Pathogenic infections increase morbidity and reduce performance in livestock, and thus understanding the comprehensive physiological changes associated with infections can benefit production sustainability. In this study, we sought to investigate...
4.
A potential role for mTORC1/2 in β adrenergic regulation of skeletal muscle glucose oxidation in models of intrauterine growth restriction
Posont R, Cadaret C, Barnes T, Yates D
Diabesity . 2021 Apr; 3(3):9-12. PMID: 33834090
The epidemic of intrauterine growth restriction (IUGR) continues to be a leading cause of perinatal morbidity and mortality throughout the world. This condition has been linked to the development of...
5.
Maternofetal inflammation induced for 2 wk in late gestation reduced birth weight and impaired neonatal growth and skeletal muscle glucose metabolism in lambs
Posont R, Cadaret C, Beard J, Swanson R, Gibbs R, Marks-Nelson E, et al.
J Anim Sci . 2021 Mar; 99(5). PMID: 33780540
Intrauterine stress impairs growth and metabolism in the fetus and offspring. We recently found that sustained maternofetal inflammation resulted in intrauterine growth-restricted (MI-IUGR) fetuses with asymmetric body composition, impaired muscle...
6.
Intermittent maternofetal O supplementation during late gestation rescues placental insufficiency-induced intrauterine growth restriction and metabolic pathologies in the neonatal lamb
Cadaret C, Posont R, Swanson R, Beard J, Barnes T, Beede K, et al.
Transl Anim Sci . 2020 Dec; 3(Suppl 1):1696-1700. PMID: 33336152
No abstract available.
7.
Body composition estimated by bioelectrical impedance analyses is diminished by prenatal stress in neonatal lambs and by heat stress in feedlot wethers
Gibbs R, Cadaret C, Swanson R, Beede K, Posont R, Schmidt T, et al.
Transl Anim Sci . 2019 Dec; 3(Suppl 1):1691-1695. PMID: 31867570
No abstract available.

Maternal inflammation at 0.7 gestation in ewes leads to intrauterine growth restriction and impaired glucose metabolism in offspring at 30 d of age
Posont R, Cadaret C, Beede K, Beard J, Swanson R, Gibbs R, et al.
Transl Anim Sci . 2019 Dec; 3(Suppl 1):1673-1677. PMID: 31867569

Sustained maternal inflammation during the early third-trimester yields intrauterine growth restriction, impaired skeletal muscle glucose metabolism, and diminished β-cell function in fetal sheep1,2
Cadaret C, Merrick E, Barnes T, Beede K, Posont R, Petersen J, et al.
J Anim Sci . 2019 Oct; 97(12):4822-4833. PMID: 31616931
Maternal inflammation causes fetal intrauterine growth restriction (IUGR), but its impact on fetal metabolism is not known. Thus, our objective was to determine the impact of sustained maternal inflammation in...

Postnatal Nutrient Repartitioning due to Adaptive Developmental Programming
Posont R, Yates D
Vet Clin North Am Food Anim Pract . 2019 May; 35(2):277-288. PMID: 31103181
Fetal stress induces developmental adaptations that result in intrauterine growth restriction (IUGR) and low birthweight. These adaptations reappropriate nutrients to the most essential tissues, which benefits fetal survival. The same...
