Mitogen-activated protein kinases (MAPKs) regulate diverse aspects of plant growth. However, their potential role in reproductive development remains elusive. Here, we discovered an unique role of SlMPK20, a plant-specific group D MAPK, in pollen development in tomato. RNAi-mediated suppression of SlMPK20 or its knockout using CRISPR/Cas9 significantly reduced or completely abolished pollen viability, respectively, with no effects on maternal fertility. Cell biology and gene expression analyses established that SlMPK20 exerts its role specifically at the uni-to-binucleate transition during microgametogenesis...

We aimed to investigate the different effects of low oxygen (5% O2 ) and atmospheric oxygen (20% O2 ) on in vitro fertilization for older poor ovarian responders (PORs). We selected 1080 older PORs who met two criteria: (i) advanced maternal age (≥40) and (ii) an abnormal ovarian reserve test. All the patients used the ultra-short term protocols with GnRH agonist and recombinant FSH for controlled ovarian hyperstimulation (COH). About 506 cycles were performed in the incubators with 5% O2 and 574 cycles were performed in the incubators with 20% O2 ...

BACKGROUND: Individuals born extremely preterm are exposed to significant perinatal stresses that are associated with an increased risk of psychopathology. However, a paucity of longitudinal studies has prevented the empirical examination of long-term, dynamic effects of perinatal adversity on mental health. Here, internalizing and externalizing problems from adolescence through adulthood were compared in individuals born at extremely low birth weight (ELBW; <1,000 g) and normal birth weight (NBW; >2,500 g)...

INTRODUCTION: In 2010, the WHO recommended women living with HIV breastfeed for 12 months while taking antiretroviral therapy (ART) to balance breastfeeding benefits against HIV transmission risks. To inform the 2016 WHO guidelines, we updated prior research on the impact of breastfeeding duration on HIV-free infant survival (HFS) by incorporating maternal ART duration, infant/child mortality and mother-to-child transmission data. METHODS: Using the Cost-Effectiveness of Preventing AIDS Complications (CEPAC)-Infant model, we simulated the impact of breastfeeding duration on 24-month HFS among HIV-exposed, uninfected infants...

OBJECTIVE: In utero exposure to valproic acid (VPA) has been associated with worse pregnancy outcomes compared to all other antiepileptic drugs. We have previously shown that VPA alters the expression of placental transporters for hormones and nutrients in vitro and in pregnant mice. Here, our aim was to characterize the effects of short exposure to VPA on the expression of carriers for compounds essential for fetal development in human placentas ex vivo, under controlled conditions...

Psychosocial stress may impair immune functions and provoke the development of pathologies. The underlying communication between the brain and the immune system is being studied predominantly in rodents. However, pigs offer several advantages as preclinical models for humans because pigs are more similar to humans than rodents in many anatomical and physiological characteristics. Unlike in rodents, the main stress-induced glucocorticoid in humans and pigs is cortisol with a similar circadian rhythm. In this study, we summarize data on short-term and long-term effects of social stress in pigs for their immunity and neuroendocrine regulation with consequences for their health and well-being...

Phthalates are known endocrine disruptors and associated with decreased fecundity, pregnancy loss, and adverse obstetrical outcomes, however the underlying mechanisms remain to be established. Environmental factors can influence gene expression and cell function by modifying epigenetic marks, impacting the developing embryo as well as future generations of offspring. The impact of phthalates on placental gene methylation and expression is largely unknown. We studied the effect of maternal phthalate exposure on the human placental DNA methylome and transcriptome...

Embryonic development begins under the control of maternal gene products, mRNAs and proteins that the mother deposits into the egg; the zygotic genome is activated some time later. Maternal control of early development is conserved across metazoans. Gene products contributed by mothers are critical to many early developmental processes, and set up trajectories for the rest of development. Maternal deposition of these factors is an often-overlooked aspect of parental investment. If the mother experiences challenging environmental conditions, such as poor nutrition, previous studies in Drosophila melanogaster have demonstrated a plastic response wherein these mothers may produce larger eggs to buffer the offspring against the same difficult environment...

This study investigates relations of maternal N-3 and N-6 polyunsaturated fatty acids (PUFA) intake during pregnancy with offspring body mass index (BMI), height z-score and metabolic risk (fasting glucose, C-peptide, leptin, lipid profile) during peripuberty (8-14 years) among 236 mother-child pairs in Mexico. We used food frequency questionnaire data to quantify trimester-specific intake of N-3 alpha-linolenic acid, eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA); N-6 linoleic acid and arachidonic acid (AA); and N-6:N-3 (AA:EPA+DHA), which accounts for the fact that the two PUFA families have opposing effects on physiology...

I exploit substantial increases in the earned income tax credit to study how a policy-driven change in family income affects childhood obesity. Using the National Longitudinal Survey of Youth 1979, my difference-in-differences estimates indicate that the probability of being obese increased by 3 percentage points among children whose families experienced a greater income shock. A further investigation suggests that a reduction in maternal time with children played a greater role in children's weight gain than income...

This study examined the associations among maternal depression, mothers' emotional and material investment in their child, and children's cognitive functioning. Middle-class Chilean mothers and children (N = 875; 52% males) were studied when children were 1, 5, 10, and 16 years (1991-2007). Results indicated that highly depressed mothers provided less emotional and material support to their child across all ages, which related to children's lower IQ. Children with lower mental abilities at age 1 received less learning-material support at age 5, which led to mothers' higher depression at child age 10...

BACKGROUND: Children born to HIV-infected mothers are at risk for neurodevelopmental delay. Little is known about neurodevelopmental outcomes of infants and toddlers who were born to HIV-positive mothers but were not themselves infected by HIV, especially in poor rural areas. This study was conducted to compare developmental outcomes between young children who were HIV-exposed but uninfected (HEU) and their HIV-unexposed and uninfected (HUU) peers in rural Yunnan, China. METHODS: A total of 250 HEU children aged 6-36 months and 250 HUU children matched on age, gender and residency were recruited from rural Yunnan, China...

Te-Sha Tsai, Justin C St John
Mitochondrial DNA (mtDNA) deficient metaphase II porcine oocytes are less likely to fertilize and more likely to arrest during preimplantation development. However, they can be supplemented with autologous populations of mitochondria at the time of fertilization, which significantly increases mtDNA copy number by the 2-cell stage due to the modulation of DNA methylation at a CpG island of the gene encoding mtDNA-specific polymerase, POLG, and promotes preimplantation development. Although mitochondrial supplementation does not increase development rates or mtDNA copy number in oocytes with normal levels of mtDNA copy number, we tested whether this approach would also impact on chromosomal gene expression patterns in these oocytes at each stage of preimplantation development...
