Liver-specific loss of perturbs lipid metabolism and hepatocyte integrity.

Autophagy Rep

September 2025

Division of Neurosciences & Cellular Structure, Eunice Kennedy Shriver National Institute of Child Health and Human Development, National Institutes of Health, Bethesda, MD, USA.

The autophagy-related protein ATG9A is integral to cellular autophagy and lipid mobilization, yet its importance in mammalian physiology remains underexplored. Using a liver-specific conditional knockout (-cKO) mouse model, we uncovered critical insights into the physiological function of ATG9A in this organ. -cKO mice exhibited hepatomegaly, abnormal hepatocyte morphology, mitochondrial fragmentation, and lipid droplet accumulation.

Background: Twin and singleton growth might be adaptively different to maximise survival in a shared intrauterine environment, translating to smaller average twin birthweight. We aimed to compare growth trajectories and risks of overweight and obesity between twins and singletons.

Methods: We leveraged height, weight, and BMI data from two large and ongoing nationally representative cohorts, the Millennium Cohort Study (MCS) and the National Longitudinal Survey of Youth-Child and Young Adult (NLSY-CYA), that have prospectively collected data from children born in the UK between Sept 1, 2000, and Jan 11, 2002, and participants born in the USA between December, 1970, and January, 2008, respectively, every 2-3 years from birth to adulthood.

Five issues about three cognitive caregiving practices are addressed in mothers, fathers, and children's other caregivers in nationally representative samples from 51 low- and middle-income countries with 159,959 36- to 59-month-old children. The five issues include base rates of cognitive caregiving practices of mothers, fathers, and other caregivers of young children, associations of cognitive caregiving practices of the three caregivers with children's development, associations among the three caregivers' cognitive caregiving practices, comparison of the three caregivers' cognitive caregiving practices with girls and boys, and assessments of how overall national development relates to the three caregivers' cognitive caregiving practices. The data addressing these five issues derive from the maternal reports in UNICEF's Multiple Indicator Cluster Surveys.

A novel and evolutionarily conserved inhibitory circuit selectively regulates dentate gyrus mossy cell function.

Res Sq

August 2025

Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD), Section on Cellular and Synaptic Physiology, National Institutes of Health (NIH), Bethesda, MD 20892 USA.

The mammalian dentate gyrus contributes to mnemonic function by parsing similar events and places. The disparate activity patterns of mossy cells and granule cells are believed to enable this function yet the mechanisms that drive this circuit dynamic remain elusive. We identified a novel inhibitory interneuron subtype, characterized by VGluT3 expression, with overwhelming target selectivity for mossy cells while also revealing that CCK, PV, SST and VIP interneurons preferentially innervate granule cells.

BLOC-1 and BORC: Complex regulators of endolysosomal dynamics.

Cell Chem Biol

August 2025

Division of Neuroscience and Cellular Structure, Eunice Kennedy Shriver National Institute of Child Health and Human Development, National Institutes of Health, Bethesda, MD 20892, USA. Electronic address:

Endolysosomes are dynamic organelles that undergo movement along the cytoskeleton, fusion, fission, and tubulation during their lifetime. These processes are regulated by complex molecular machineries, including the structurally related hetero-octameric complexes BLOC-1 and BORC. BLOC-1 associates with early endosomes to mediate the biogenesis of lysosome-related organelles (LROs), such as melanosomes and platelet dense bodies.

Prior studies have observed impacts of air pollution on semen quality, but timing of exposure during developmental windows of spermatogenesis and impacts of low-to-moderate air pollution is less well understood. We examined the relation between air pollution and semen quality in the Folic Acid and Zinc Supplementation Trial (2013-2018), which enrolled male partners of couples seeking infertility treatment in the Salt Lake City, Utah region (n = 2015). Semen quality parameters were assessed at baseline, 2-, 4-, and 6-months follow-up.

Background: Before Zika virus (ZIKV) infections were observed in the Americas, an association between ZIKV and microcephaly or other congenital malformations was not well documented. Initial reports suggested strong associations between ZIKV and congenital malformations, but plausible estimates of causal effects from prospective studies with adequate sample size and covariate data were few.

Methods: From 2016-2018, the Zika in Infants and Pregnancy (ZIP) study enrolled pregnant people before 18 weeks gestation or with confirmed symptomatic ZIKV in a prospective cohort across 10 sites in South and Central America, and in Puerto Rico.

Bayesian additive tree ensembles for composite quantile regressions.

Stat Comput

August 2025

Eunice Kennedy Shriver National Institute of Child Health and Human Development, National Institutes of Health, Maryland, USA.

In this paper, we introduce a novel approach that integrates Bayesian additive regression trees (BART) with the composite quantile regression (CQR) framework, creating a robust method for modeling complex relationships between predictors and outcomes under various error distributions. Unlike traditional quantile regression, which focuses on specific quantile levels, our proposed method, composite quantile BART, offers greater flexibility in capturing the entire conditional distribution of the response variable. By leveraging the strengths of BART and CQR, the proposed method provides enhanced predictive performance, especially in the presence of heavy-tailed errors and non-linear covariate effects.

Development of the Visual Analysis of Form and Contour.

Children (Basel)

July 2025

Eunice Kennedy Shriver National Institute of Child Health and Human Development, National Institutes of Health, United States Department of Health and Human Services, Bethesda, MD 20892, USA.

Background/objectives: A common approach to investigating visual form processing is through studying responses to visual stimuli that comprise illusory contours. Such stimuli induce contours where none exist physically and thus reveal the constructive nature of visual perception and the conditions that engender it. The present work used IC stimuli to study the development of visual form detection and extraction in infants and adults.

Objective: Resource-based models of self-regulation posit that cognitive fatigue, or the depletion of cognitive resources, may be an impetus for self-regulatory difficulties, including overeating. Studies of adults indicate that cognitive fatigue may increase energy intake only among adults who report engaging in dietary restraint (DR). The current study examined if DR similarly moderates the effects of cognitive fatigue on energy intake in youth.

Disentangling consequences of self-perceived weight from excess adiposity in metabolically healthy overweight/obesity.

BMC Public Health

August 2025

Biostatistics and Bioinformatics Branch, Division of Population Health Research, Eunice Kennedy Shriver National Institute of Child Health and Human Development, National Institutes of Health, Bethesda, MD, USA.

Background: Greater self-perceived weight is detrimental to cardiometabolic health among people with overweight/obesity. However, it is impractical to test and unknown whether weight-related psychosocial factors, like self-perceived weight, independently affect cardiometabolic health apart from physiological dysregulation produced by excess adiposity among people with overweight/obesity. Metabolically healthy overweight/obesity (MHOv/Ob) involves overweight/obesity, but with the absence of metabolic dysfunction.

LC3 and GABARAP independent autophagy of misfolded procollagen in mouse osteoblasts.

Autophagy

August 2025

Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD), National Institutes of Health, Bethesda, MD, USA.

Bone synthesis should depend on autophagy because over 10% of type I procollagen (PC1) - a heterotrimer of COL1A1 and COL1A2 chains and the precursor of the main bone matrix molecule - is misfolded and rerouted from osteoblast endoplasmic reticulum (ER) to lysosomes. However, osteoblast-specific macroautophagy knockouts in mice have produced only mild bone effects. To reconcile these observations, we compared how hypomorphic expression and a conditional knockout (cKO) of - encoding a protein required for autophagosome formation - affected versus wild-type osteoblasts and .

The hereditary spastic paraplegia type 21 (SPG21) protein is a RAB7A effector that promotes mTORC1-catalyzed TFEB phosphorylation and cytoplasmic retention.

Mol Biol Cell

August 2025

Division of Neurosciences & Cellular Structure, Eunice Kennedy Shriver National Institute of Child Health and Human Development, National Institutes of Health, Bethesda, Maryland, 20892, USA.

Hereditary spastic paraplegia type 21 (SPG21) is an inherited neurological disorder caused by biallelic mutations in the gene, which encodes a protein named SPG21 or maspardin. Herein, we report that the SPG21 protein localizes to endolysosomes through interaction with the GTP-bound form of RAB7A. Disease-associated variants reduce expression of SPG21 and disrupt its endolysosomal localization in both non-neuronal cells and neurons.

Unit on Chromosome Dynamics, Division of Development Biology, Eunice Kennedy Shriver National Institute of Child Health and Human Development, National Institutes of Health, Bethesda, Maryland, 20982, USA.

The goal of meiosis is typically to produce haploid gametes (eggs or sperm). Failure to do so is catastrophic for fertility and offspring health. However, Lepidopteran (moths and butterflies) males produce two morphs of sperm: nucleated (eupyrene) sperm which fertilize the egg, and anucleated (apyrene) sperm, both of which are essential for fertilization.

Vertebrate inner ear mechanosensory hair cells detect sound and gravitational forces. Additionally, fishes have homologous lateral line hair cells in the skin that detect water vibrations for orientation and predator avoidance. Hair cells in the lateral line and ear of fishes and other non-mammalian vertebrates regenerate readily after damage, but mammalians lack this ability, causing deafness and vestibular defects.
