Maternal Oxycodone Treatment Results in Neurobehavioral Disruptions in Mice Offspring.

eNeuro 2021 Jul 26. Epub 2021 Jul 26.

Christopher S Bond Life Sciences Center, University of Missouri, Columbia, MO 65211 USA

Opioid drugs are increasingly being prescribed to pregnant women. Such compounds can also bind and activate opioid receptors in the fetal brain, which could lead to long term brain and behavioral disruptions. We hypothesized that maternal treatment with oxycodone (OXY), the primary opioid at the center of the current crisis, leads to later neurobehavioral disorders and gene expression changes in the hypothalamus and hippocampus of resulting offspring.

Caste development and sex ratio of the Ryukyu drywood termite Neotermes sugioi and its potential mechanisms.

Sci Rep 2021 Jul 22;11(1):15037. Epub 2021 Jul 22.

Field Science Education and Research Center, Hokkaido Forest Research Station, Kyoto University, 553 Tawa, Shibecha-cho, Kawakami-gun, Hokkaido, 088-2339, Japan.

Sex allocation is one of the most studied traits in evolutionary biology because its theoretical predictions match the empirical data. Here, using the Ryukyu dry-wood termite Neotermes sugioi, we investigated several factors that could bias the sex allocation in three populations (Okinawa, Ishigaki/Iriomote, and Yonaguni). Our survey showed that there were more queen-only colonies than king-only colonies in these populations, suggesting a longer lifespan of the queens than that of the kings. Read More

Placental insufficiency induces a sexually dimorphic response in the expression of cardiac growth and metabolic signalling molecules upon exposure to a postnatal western diet in guinea pigs.

J Dev Orig Health Dis 2021 Jul 26:1-13. Epub 2021 Jul 26.

Early Origins of Adult Health Research Group, Health and Biomedical Innovation, UniSA: Clinical and Health Sciences, University of South Australia, Adelaide, SA, Australia.

There is a strong relationship between low birth weight (LBW) and an increased risk of developing cardiovascular disease (CVD). In postnatal life, LBW offspring are becoming more commonly exposed to the additional independent CVD risk factors, such as an obesogenic diet. However, how an already detrimentally programmed LBW myocardium responds to a secondary insult, such as an obesogenic diet (western diet; WD), during postnatal life is ill defined. Read More

Podocyte endowment and the impact of adult body size on kidney health.

Am J Physiol Renal Physiol 2021 07 26. Epub 2021 Jul 26.

Stem Cells and Development Program, Monash Biomedicine Discovery Institute and the Department of Anatomy and Developmental Biology, Monash University, Melbourne, Australia.

Low birth weight is a risk factor for chronic kidney disease (CKD), while adult podocyte depletion is a key event in the pathogenesis of glomerulosclerosis. However, whether low birth weight due to poor maternal nutrition is associated with low podocyte endowment and glomerulosclerosis in later life is not known. Female Sprague-Dawley rats were fed a normal (NPD, 20%) or low (LPD, 8%) protein diet from 3 weeks before mating until postnatal day 21 (PN21), when kidneys from some male offspring were taken for quantitation of podocyte number and density in whole glomeruli using immunolabeling, tissue clearing and confocal microscopy.

Sperm length divergence as a potential prezygotic barrier in a passerine hybrid zone.

Ecol Evol 2021 Jul 16;11(14):9489-9497. Epub 2021 Jun 16.

Natural History Museum University of Oslo Oslo Norway.

The saltmarsh sparrow and Nelson's sparrow differ in ecological niche, mating behavior, and plumage, but they hybridize where their breeding distributions overlap. In this advanced hybrid zone, past interbreeding and current backcrossing result in substantial genomic introgression in both directions, although few hybrids are currently produced in most locations. However, because both species are nonterritorial and have only brief male-female interactions, it is difficult to determine to what extent assortative mating explains the low frequency of hybrid offspring.

Cardiovascular and Cerebrovascular Implications of Growth Restriction: Mechanisms and Potential Treatments.

Int J Mol Sci 2021 Jul 14;22(14). Epub 2021 Jul 14.

The Ritchie Centre, Hudson Institute of Medical Research, Clayton 3168, Australia.

Fetal growth restriction (FGR) is a common complication of pregnancy, resulting in a fetus that fails to reach its genetically determined growth potential. Whilst the fetal cardiovascular response to acute hypoxia is well established, the fetal defence to chronic hypoxia is not well understood due to experiment constraints. Growth restriction results primarily from reduced oxygen and nutrient supply to the developing fetus, resulting in chronic hypoxia. Read More

Perinatal High-Fat Diet Influences Ozone-Induced Responses on Pulmonary Oxidant Status and the Molecular Control of Mitophagy in Female Rat Offspring.

Int J Mol Sci 2021 Jul 14;22(14). Epub 2021 Jul 14.

Department of Pharmacology and Toxicology, NUTRIM School of Nutrition and Translational Research in Metabolism, Maastricht University, 6200 Maastricht, The Netherlands.

Previous research has shown that a perinatal obesogenic, high-fat diet (HFD) is able to exacerbate ozone-induced adverse effects on lung function, injury, and inflammation in offspring, and it has been suggested that mitochondrial dysfunction is implicated herein. The aim of this study was to investigate whether a perinatal obesogenic HFD affects ozone-induced changes in offspring pulmonary oxidant status and the molecular control of mitochondrial function. For this purpose, female Long-Evans rats were fed a control diet or HFD before and during gestation, and during lactation, after which the offspring were acutely exposed to filtered air or ozone at a young-adult age (forty days).

In Utero Exposure to Δ9-Tetrahydrocannabinol Leads to Postnatal Catch-Up Growth and Dysmetabolism in the Adult Rat Liver.

Int J Mol Sci 2021 Jul 13;22(14). Epub 2021 Jul 13.

Department of Physiology and Pharmacology, Schulich School of Medicine and Dentistry, Western University, 1151 Richmond Street, London, ON N6A 5C1, Canada.

The rates of gestational cannabis use have increased despite limited evidence for its safety in fetal life. Recent animal studies demonstrate that prenatal exposure to Δ9-tetrahydrocannabinol (Δ9-THC, the psychoactive component of cannabis) promotes intrauterine growth restriction (IUGR), culminating in postnatal metabolic deficits. Given IUGR is associated with impaired hepatic function, we hypothesized that Δ9-THC offspring would exhibit hepatic dyslipidemia. Read More

Sex differences in the impact of parental obesity on offspring cardiac SIRT3 expression, mitochondrial efficiency and diastolic function early in life.

Am J Physiol Heart Circ Physiol 2021 07 23. Epub 2021 Jul 23.

Department of Physiology and Biophysics, Mississippi Center for Obesity Research, Cardiorenal and Metabolic Diseases Research Center, University of Mississippi Medical Center, Jackson, MS, United States.

Previous studies suggest that parental obesity may adversely impact long-term metabolic health of the offspring. We tested the hypothesis that parental (paternal + maternal) obesity impairs cardiac function in the offspring early in life. Within 1-3 days after weaning, offspring from obese rats fed a high fat diet (HFD-Offs) and age-matched offspring from lean rats (ND-Offs) were submitted to echocardiography and cardiac catheterization for assessment of pressure-volume relationships.

Perinatal SSRI exposure disrupts G protein-coupled receptor BAI3 in developing dentate gyrus and adult emotional behavior: relevance to psychiatric disorders.

Neuroscience 2021 Jul 19. Epub 2021 Jul 19.

School of Neuroscience, Virginia Polytechnic Institute and State University, Blacksburg, VA, 24061, USA. Electronic address:

Selective serotonin reuptake inhibitor (SSRI) antidepressants are widely prescribed to pregnant women suffering with depression, although the long-term impact of these medications on exposed offspring are poorly understood. Perinatal SSRI exposure alters human offspring's neurodevelopment and increases risk for psychiatric illness in later life. Rodent studies suggest that perinatal SSRI-induced behavioral abnormalities are driven by changes in the serotonin system as well as epigenetic and transcriptomic changes in the developing hippocampus.

Male microchimerism in females: a quantitative study of twin pedigrees to investigate mechanisms.

Hum Reprod 2021 Jul 19. Epub 2021 Jul 19.

Amsterdam Reproduction and Development (AR&D) Research Institute, Amsterdam UMC, Vrije Universiteit, Amsterdam, The Netherlands.

Study Question: Does having a male co-twin, older brothers, or sons lead to an increased probability of persistent male microchimerism in female members of twin pedigrees?

Summary Answer: The presence of a male co-twin did not increase risk of male microchimerism and the prevalence of male microchimerism was not explained by having male offspring or by having an older brother.

What Is Known Already: Microchimerism describes the presence of cells within an organism that originate from another zygote and is commonly described as resulting from pregnancy in placental mammals. It is associated with diseases with a female predilection including autoimmune diseases and pregnancy-related complications. Read More

Early-life social experience affects offspring DNA methylation and later life stress phenotype.

Nat Commun 2021 07 20;12(1):4398. Epub 2021 Jul 20.

Department of Epidemiology and Lifecourse Epidemiology of Adiposity and Diabetes (LEAD) Center, University of Colorado Denver, Aurora, CO, USA.

Studies in rodents and captive primates suggest that the early-life social environment affects future phenotype, potentially through alterations to DNA methylation. Little is known of these associations in wild animals. In a wild population of spotted hyenas, we test the hypothesis that maternal care during the first year of life and social connectedness during two periods of early development leads to differences in DNA methylation and fecal glucocorticoid metabolites (fGCMs) later in life.
