Leptin Receptor Neurons In The Dorsomedial Hypothalamus Require Distinct Neuronal Subsets For Thermogenesis And Weight Loss, Marie Francois, Laura Kaiser, Yanlin He, Yong Xu, J Michael Salbaum, Sangho Yu, Christopher D Morrison, Hans-Rudolf Berthoud, Heike Münzberg

Children’s Nutrition Research Center Staff Publications

The dorsomedial hypothalamus (DMH) receives inputs from the preoptic area (POA), where ambient temperature mediates physiological adaptations of energy expenditure and food intake. Warm-activated POA neurons suppress energy expenditure via brown adipose tissue (BAT) projecting neurons in the dorsomedial hypothalamus/dorsal hypothalamic area (dDMH/DHA). Our earlier work identified leptin receptor (Lepr)-expressing, BAT-projecting dDMH/DHA neurons that mediate metabolic leptin effects. Yet, the neurotransmitter (glutamate or GABA) used by dDMH/DHALepr neurons remains unexplored and was investigated in this study using mice. We report that dDMH/DHALepr neurons represent equally glutamatergic and GABAergic neurons. Surprisingly, chemogenetic activation of glutamatergic and/or GABAergic dDMH/DHA neurons were capable …

Children’s Nutrition Research Center Staff Publications

β-Hydroxybutyrate (BHB) is an abundant ketone body. To date, all known pathways of BHB metabolism involve the interconversion of BHB and primary energy intermediates. Here, we identify a previously undescribed BHB secondary metabolic pathway via CNDP2-dependent enzymatic conjugation of BHB and free amino acids. This BHB shunt pathway generates a family of anti-obesity ketone metabolites, the BHB-amino acids. Genetic ablation of CNDP2 in mice eliminates tissue amino acid BHB-ylation activity and reduces BHB-amino acid levels. The most abundant BHB-amino acid, BHB-Phe, is a ketosis-inducible congener of Lac-Phe that activates hypothalamic and brainstem neurons and suppresses feeding. Conversely, CNDP2-KO mice exhibit …

Characterizing Fermentable Carbohydrate Foods In The Diets Of Children With Abdominal Pain-Related Disorders Of Gut-Brain Interaction And Healthy Children, Vishnu Narayana, Jocelyn Chang, Ann R Mcmeans, Tasha Murphy, Rona L Levy, Robert J Shulman, Bruno P Chumpitazi

Children’s Nutrition Research Center Staff Publications

Objectives: Restricting dietary fermentable oligosaccharides, disaccharides, monosaccharides, and polyols (FODMAPs) can alleviate symptoms in children with disorders of gut-brain interaction (DGBI). Due to the restrictions of a low FODMAP diet (LFD), a less restrictive FODMAP Gentle diet (FGD) has been suggested. However, the types and amounts of high FODMAP foods and carbohydrates commonly consumed by children have not been studied. We aimed to identify the high FODMAP foods and proportions of FODMAP carbohydrates consumed by children with DGBI and healthy children (HC) and to determine which usually ingested FODMAPs would be restricted on the FGD.

Methods: Three-day diet records from …

Children’s Nutrition Research Center Staff Publications

INTRODUCTION: Spinach produces an array of unique flavonoids not commonly found in other fruits and vegetables. These molecules likely serve as defense agents against biotic and abiotic stress and may have health beneficial properties for humans. Current methods to analyze spinach flavonoids are incomplete and only capture a portion of this uncharacterized pathway. A comprehensive analysis method is needed to determine how genetics, environmental conditions, and other factors influence spinach flavonoid biosynthesis.

METHODS: We developed and validated a high-throughput extraction and ultra high-performance liquid chromatography tandem mass spectrometry (UHPLC-MS/MS) method to separate and quantify 39 spinach flavonoid species in 11.5 …

New Genetic Tools To Define The Pathophysiology Of Inborn Errors Of Cobalamin Metabolism Impacting Mammalian Development, Tiffany Chern, Xuefei Tong, William G Bauer, David J Quispe-Parra, Xia Gao, Kamryn N Gerner-Mauro, Ross A Poché

Children’s Nutrition Research Center Staff Publications

The congenital, autosomal recessive disorder combined methylmalonic acidemia and homocystinuria - cblC type, is the most common inborn error of cobalamin (vitamin B12) metabolism. In its early onset form, cblC profoundly impacts fetal development of the central nervous system, hematopoietic system, and other tissues. Previously, mutations in the MMACHC gene, which encodes a protein required for the intracellular trafficking and enzymatic processing of free cobalamin into active coenzyme forms, were found to cause cblC. These coenzymes are required in two metabolic pathways which produce either succinyl-CoA in the mitochondria or methionine in the cytosol. However, due to a lack of …

Children’s Nutrition Research Center Staff Publications

In solid organ transplantation, especially renal transplantation, for the induction of immune tolerance, accumulating evidence has revealed that Regulatory B cells (Breg) play a crucial role in stimulating immune tolerance, alleviating immune responses, and improving graft survival. We describe the heterogeneous nature of Bregs, focusing on their defining surface markers and regulatory functions. Meanwhile, the major cytokine secretion function and the correlation between Breg and Treg or other immune checkpoints to balance the immune responses are addressed. Furthermore, we summarized the intrinsic and extrinsic pathways or costimulatory stimuli for the differentiation from naïve B cells. More importantly, we summarized the …

A Reflection-Spectroscopy Measured Skin Carotenoid Score Strongly Correlates With Plasma Concentrations Of All Major Dietary Carotenoid Species Except For Lycopene, Qiang Wu, Cheryl Webb Cherry, Stephanie Jilcott Pitts, Melissa N Laska, Neal Craft, Nancy E Moran

Children’s Nutrition Research Center Staff Publications

Skin carotenoids can be measured non-invasively using spectroscopy methods to provide a biomarker of total dietary carotenoid and carotenoid-rich fruit and vegetable intake. However, the degree to which skin carotenoid biomarkers reflect intakes of specific carotenoids must be determined for specific devices. Previously, findings were mixed regarding the correlation between reflection spectroscopy (RS)-assessed skin carotenoids and individual plasma carotenoid concentrations. The current study expands on prior analyses to examine the cross-sectional associations between adult RS-assessed skin carotenoids and individual carotenoid species intakes and plasma concentrations, controlling for potential covariates. We hypothesized that RS-assessed skin carotenoid scores would strongly correlate with …

Children’s Nutrition Research Center Staff Publications

Single-cell RNA sequencing and spatial transcriptomics enable unprecedented insight into cellular and molecular pathways implicated in human skin aging and regeneration. Senescent cells are individual cells that are irreversibly cell cycle arrested and can accumulate across the human lifespan due to cell-intrinsic and -extrinsic stressors. With an atlas of single-cell RNA-sequencing and spatial transcriptomics, epidermal and dermal senescence and its effects were investigated, with a focus on melanocytes and fibroblasts. Photoaging due to ultraviolet light exposure was associated with higher burdens of senescent cells, a sign of biological aging, compared to chronological aging. A skin-specific cellular senescence gene set, termed …

Relative Uptake Of Tomato Carotenoids By In Vitro Intestinal And Prostate Cancer Cells, Nancy E Moran, Brianna Alexander, Shivi Garg, Nathan Marchant, Noor A Hason

Children’s Nutrition Research Center Staff Publications

Background: Consumption of tomatoes and tomato carotenoids is associated with a reduced risk of prostate cancer. Prostate tissue accumulates tomato carotenoids, including lycopene, β-carotene, and phytoene. Phytoene accumulation is relatively greater in the prostate than that of lycopene, but the metabolic determinants of tissue carotenoid profiles are poorly understood.

Objectives: The purpose of this study was to determine if differences in stability, cellular uptake, and clearance of phytoene compared with lycopene or β-carotene by prostate and intestinal cells may explain differences in observed tissue carotenoid profiles.

Methods: Gene and protein expression for carotenoid metabolism in prostate cell lines were analyzed …

Associations Between Metabolic Disorders And Sjögren’S Disease, Chihiro Iwaya, Junichi Iwata

Faculty, Staff and Student Publications

Sjögren’s disease (SjD) is a systemic autoimmune disorder characterized by dry eyes and mouth caused by chronic inflammation and is often accompanied by various extra-glandular manifestations, including fatigue and diffuse pain. Although the pathogenesis of the disease remains elusive, several factors (e.g. environmental, genetic and hormonal factors, abnormal metabolic status) are associated with this condition. Accumulating evidence suggests a potential role of cholesterol metabolism in immune and non-immune modulation in various diseases. In this review, we summarize the current findings on the associations between cholesterol metabolism and SjD.

Mechanistic Diversity And Functional Roles Define The Substrate Specificity And Ligand Binding Of Bacterial Pgp Phosphatases, Wei Niu, Joanne Shi Woon Lam, Trung Vu, Guangwei Du, Hao Fan, Lei Zheng

Faculty, Staff and Student Publications

Phosphatidylglycerol is a critical membrane phospholipid in microorganisms, synthesized via the dephosphorylation of phosphatidylglycerol-phosphate (PGP) by three membrane-bound phosphatases: PgpA, PgpB, and PgpC. While any one of these enzymes can produce phosphatidylglycerol at WT levels, the reason for the presence of all three in bacteria remains unclear. To address this question, we characterized these phosphatases in vitro to uncover their mechanistic differences. Our assays demonstrated that all three enzymes catalyze the hydrolysis of PGP but exhibit distinct substrate selectivity. PgpB displays a broad substrate range, dephosphorylating various lipid phosphates, while PgpA and PgpC show a higher specificity for lysophosphatidic acid …

Hunting For Heroes: Brain Neurons Mediating Glp-1r Agonists In Obesity Treatment, Yuhan Cao, Qingchun Tong

Faculty, Staff and Student Publications

Glucagon-like peptide 1 (GLP-1) receptor agonists (GLP-1RAs) have proven to be highly effective in reducing obesity across species and ages, gaining unmet popularity in clinical treatments against obesity. Although extensive research efforts have been made to explore how the brain regulates body weight homeostasis including the effect brought up by GLP-1 and its synthetic analogs GLP-1RAs, the identity of neurons and neural pathways that are responsible for the observed anti-obesity effect of GLP-1RAs remain largely elusive. Excitingly, three recent high-profile studies presented compelling evidence that each argues for the importance of GLP-1Rs in the dorsomedial hypothalamus, hindbrain, or lateral septum, …
