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 …

Adipose thermogenesis has been actively investigated as a therapeutic target for improving metabolic dysfunction in obesity. However, its applicability to middle-aged and older populations, which bear the highest obesity prevalence in the United States (approximately 40%), remains uncertain due to age-related decline in thermogenic responses. In this study, we investigated the effects of chronic thermogenic stimulation using the β3-adrenergic (AR) agonist CL316,243 (CL) on systemic metabolism and adipose function in aged (18-month-old) C57BL/6JN mice. Sustained β3-AR treatment resulted in reduced fat mass, increased energy expenditure, increased fatty acid oxidation and mitochondrial activity in adipose depots, improved glucose homeostasis, and a …

TV viewing is associated with health risks, but existing measures of TV viewing are imprecise due to relying on self-report. We developed the Family Level Assessment of Screen use in the Home (FLASH)-TV, a machine learning pipeline with state-of-the-art computer vision methods to measure children's TV viewing. In three studies, lab pilot (n = 10), lab validation (n = 30), and home validation (n = 20), we tested the validity of FLASH-TV 3.0 in task-based protocols which included video observations of children for 60 min. To establish a gold-standard to compare FLASH-TV output, the videos were labeled by trained staff …

Patient Experience Journal

Objective: The effectiveness of out of hospital lifestyle interventions in healthcare is likely co-dependent on social support from involved one's. We sought to investigate the interrelationships between patient-partner Co-responsibility, Spousal Support, and Self-efficacy and the mechanisms through which they contribute to health behaviors and outcomes relevant to weight loss and maintenance. Methods: Co-responsibility, Spousal Support, self-efficacy, health outcomes and health behaviors like total weight loss, physical activity, OBESI-Q, and health satisfaction were assessed through a questionnaire among 868 individuals attempting to lose weight. Full and semi-partial correlations were used to understand the association between Co-responsibility, Spousal Support, Self-efficacy …

Faculty, Staff and Students Publications

BACKGROUND: Although some randomized trials have reported beneficial effects of protein intake on cardiometabolic risk factors, evidence from prospective studies have not supported a strong link between protein intake and cardiovascular disease (CVD) risk. It is also unclear whether diversity in protein intake plays a role in CVD risk.

OBJECTIVE: We investigated prospective associations of (1) protein intake, overall and by food source and (2) diversity of protein sources with risk of CVD, coronary heart disease (CHD), and stroke.

METHODS: In a multi-ethnic cohort of 5879 U.S. adults (45-84 years), who were free of CVD at baseline, protein intake was …

Background: The maternal-offspring relationship, such as whether fetal sex influences maternal health, is essential to explore to advance prenatal and maternal health. While associations exist between fetal sex and maternal health outcomes, it is unclear whether these reflect a causal relationship.

Objective: To demonstrate that fetal sex can be randomly assigned to test the causal effect of fetal sex on maternal outcomes.

Methods: Holstein dairy cows were stratified and randomized using sealed opaque envelopes to be artificially inseminated with either X- or Y-sorted bull semen until 40 cows became pregnant. Monthly body weight measurements were recorded, and an intravenous glucose …

Avulsion Of The Flexor Digitorum Profundus Tendon During The Curettage Of A Recurrent Enchondroma: A Case Report, Shunpei Hama, Masataka Yasuda, Makoto Fukuda, Katsuaki Onishi, Takaaki Chikugo

Children’s Nutrition Research Center Staff Publications

Enchondroma rarely occurs in the distal phalanx, and avulsion of the flexor digitorum profundus (FDP) tendon in this area is also rare. We report a case of recurrent enchondroma in the distal phalanx, which required reconstruction for an accidental FDP avulsion during surgery. A 36-year-old right-handed woman visited our hospital with a suspected recurrence of enchondroma and a planned surgery. Radiographs and computed tomography revealed three translucent lesions in the distal phalanx of her left index finger. We performed curettage and calcium phosphate bone cement (CPC) grafting. During the procedure, an avulsion of the FDP tendon was found. We reattached …

Children’s Nutrition Research Center Staff Publications

The tutelage of our mentors as scientists included the analogy that writing a good scientific paper was an exercise in storytelling that omitted unessential details that did not move the story forward or that detracted from the overall message. However, the advice to not get lost in the details had an important flaw. In science, it is the many details of the data themselves and the methods used to generate and analyze them that give conclusions their probative meaning. Facts may sometimes slow or distract from the clarity, tidiness, intrigue, or flow of the narrative, but nevertheless they are important …


Reproduction Has Immediate Effects On Female Mortality, But No Discernible Lasting Physiological Impacts: A Test Of The Disposable Soma Theory, Sharon E Mitchell, Megan Simpson, Lena Coulet, Solenn Gouedard, Catherine Hambly, Juliano Morimoto, David B Allison, John R Speakman Oct 2024

Reproduction Has Immediate Effects On Female Mortality, But No Discernible Lasting Physiological Impacts: A Test Of The Disposable Soma Theory, Sharon E Mitchell, Megan Simpson, Lena Coulet, Solenn Gouedard, Catherine Hambly, Juliano Morimoto, David B Allison, John R Speakman

Children’s Nutrition Research Center Staff Publications

The disposable soma theory (DST) posits that organisms age and die because of a direct trade-off in resource allocation between reproduction and somatic maintenance. DST predicts that investments in reproduction accentuate somatic damage which increase senescence and shortens lifespan. Here, we directly tested DST predictions in breeding and nonbreeding female C57BL/6J mice. We measured reproductive outputs, body composition, daily energy expenditure, and oxidative stress at peak lactation and over lifetime. We found that reproduction had an immediate and negative effect on survival due to problems encountered during parturition for some females. However, there was no statistically significant residual effect on …

BACKGROUND: Inflammation is a feature of coronary heart disease (CHD), but the role of proinflammatory microbial infection in CHD remains understudied.

METHODS AND RESULTS: CHD was defined in the MESA (Multi-Ethnic Study of Atherosclerosis) as myocardial infarction (251 participants), resuscitated arrest (2 participants), and CHD death (80 participants). We analyzed sequencing reads from 4421 MESA participants in the National Heart, Lung, and Blood Institute Trans-Omics for Precision Medicine program using the PathSeq workflow of the Genome Analysis Tool Kit and a 65-gigabase microbial reference. Paired reads aligning to 840 microbes were detected in >1% of participants. The association of the …


Pulmonary Vascular Manifestations Of Hereditary Haemorrhagic Telangiectasia, Sarah Cullivan, Barry Kevane, Brian Mccullagh, Terry M O'Connor, Robin Condliffe, Sean Gaine Oct 2024

Pulmonary Vascular Manifestations Of Hereditary Haemorrhagic Telangiectasia, Sarah Cullivan, Barry Kevane, Brian Mccullagh, Terry M O'Connor, Robin Condliffe, Sean Gaine

Children’s Nutrition Research Center Staff Publications

Hereditary haemorrhagic telangiectasia (HHT) is an autosomal dominant, multisystem disorder that manifests with a spectrum of disease including cardiopulmonary complications. HHT is characterised by aberrant signalling via the transforming growth factor β (TGFβ) pathway, with loss of vascular integrity, angiogenesis and vascular dysplasia. The disease has an estimated prevalence of 1 in 5000 persons and the penetrance increases with increasing age. HHT commonly presents with epistaxis and telangiectasia, while visceral arteriovenous malformations are not uncommon. Mutations in the ENG, ACVRL1 and MADH4 genes account for 97% of all HHT cases, and it is recommended that genetic tests are used in …


Benefits Of Calorie Restriction In Mice Are Mediated Via Energy Imbalance, Not Absolute Energy Or Protein Intake, Daniel L Smith, Sharon E Mitchell, Maria S Johnson, Victoria K Gibbs, Stephanie Dickinson, Beate Henschel, Rui Li, Kathryn A Kaiser, Daniella E Chusyd, Andrew W Brown, David B Allison, John R Speakman, Tim R Nagy Oct 2024

Caloric restriction (CR) results in reduced energy and protein intake, raising questions about protein restriction's contribution to CR longevity benefits. We kept ad libitum (AL)-fed male C57BL/6J mice at 27°C (AL27) and pair-fed (PF) mice at 22°C (22(PF27)). The 22(PF27) group was fed to match AL27 while restricted for calories due to cold-induced metabolism. The 22(PF27) mice had significantly lower body weight, lean mass, fat mass, leptin, IGF-1, and TNF-α levels than AL27 mice (p< 0.001 for all). Manipulations over ~11 weeks resulted in significant differences in body temperature, physical activity, and expression of key genes linked to hunger in the hypothalamus. Survival was significantly greater in 22(PF27) compared to AL27 overall (p< 0.001). CR in the context of equivalent energy and protein intake resulted in hormonal, metabolic, and physiological benefits and extended longevity. Hence, energy imbalance, rather than low energy or protein intake per se, mediates the benefits of CR.

Recording and analysis of neural activity are often biased toward detecting sparse subsets of highly active neurons, masking important signals carried in low-magnitude and variable responses. To investigate the contribution of seemingly noisy activity to odor encoding, we used mesoscale calcium imaging from mice of both sexes to record odor responses from the dorsal surface of bilateral olfactory bulbs (OBs). The outer layer of the mouse OB is comprised of dendrites organized into discrete "glomeruli," which are defined by odor receptor-specific sensory neuron input. We extracted activity from a large population of glomeruli and used logistic regression to classify odors …

Wearable devices such as the ActiGraph are now commonly used in research to monitor or track physical activity. This trend corresponds with the growing need to assess the relationships between physical activity and health outcomes, such as obesity, accurately. Device-based physical activity measures are best treated as functions when assessing their associations with scalar-valued outcomes such as body mass index. Scalar-on-function regression (SoFR) is a suitable regression model in this setting. Most estimation approaches in SoFR assume that the measurement error in functional covariates is white noise. Violating this assumption can lead to underestimating model parameters. There are limited approaches …

Small Gtp-Binding Protein Gdp Dissociation Stimulator Influences Cisplatin-Induced Acute Kidney Injury Via Perk-Dependent Er Stress, Yuxue Yang, Ting Xiong, Ti Wang, Xiwei Chen, Ziwei Ma, Bangyun Zuo, Dong Ning, Ruilong Song, Xuesong Liu, Daxin Wang

Children’s Nutrition Research Center Staff Publications

Cisplatin is a common anticancer drug, but its frequent nephrotoxicity limits its clinical use. Small GTP-binding protein GDP dissociation stimulator (smgGDS), a small GTPase chaperone protein, was considerably downregulated during cisplatin-induced acute kidney injury (CDDP-AKI), especially in renal tubular epithelial cells. SmgGDS-knockdown mice was established and found that smgGDS knockdown promoted CDDP-AKI, as demonstrated by an increase in serum creatine, blood urea nitrogen levels and the appearance of tubular patterns. RNA sequencing suggested that protein kinase RNA-like ER kinase (PERK), which bridges mitochondria-associated ER membranes, was involved in smgGDS knockdown following CDDP-AKI, and then identified that smgGDS knockdown increased phosphorylated-PERK …


Not Feeling The Heat? Effects Of Dietary Protein On Satiation And Satiety In Mice Are Not Due To Its Impact On Body Temperature, Jazmin Osorio M, Sharon E Mitchell, Catherine Hambly, David B Allison, John R Speakman Sep 2024

Not Feeling The Heat? Effects Of Dietary Protein On Satiation And Satiety In Mice Are Not Due To Its Impact On Body Temperature, Jazmin Osorio M, Sharon E Mitchell, Catherine Hambly, David B Allison, John R Speakman

Children’s Nutrition Research Center Staff Publications

Dietary protein modulates food intake (FI) via unclear mechanism(s). One possibility is that higher protein leads to greater post-ingestive heat production (Specific dynamic action: SDA) leading to earlier meal termination (increased satiation), and inhibition of further intake (increased satiety). The influence of dietary protein on feeding behaviour in C57BL/6J mice was tested using an automated FI monitoring system (BioDAQ), simultaneous to body temperature (Tb). Total FI, inter meal intervals (IMI, satiety) and meal size (MS, satiation) were related to changes in Tb after consuming low (5%, LP), moderate (15%, MP) and high (30%, HP) protein diets. Diets were tested over …

Natural Killer Cell Effector Function Is Critical For Host Defense Against Alcohol-Associated Bacterial Pneumonia, Daniel Villageliu, Kelly C. Cunningham, Deandra R. Smith, Daren L. Knoell, Mason Mandolfo, Todd A. Wyatt, Derrick R. Samuelson

Food for Health: Publications

Alcohol use is an independent risk factor for the development of bacterial pneumonia due, in part, to impaired mucus-facilitated clearance, macrophage phagocytosis, and recruitment of neutrophils. Alcohol consumption is also known to reduce peripheral natural killer (NK) cell numbers and compromise NK cell cytolytic activity, especially NK cells with a mature phenotype. However, the role of innate lymphocytes, such as NK cells during host defense against alcohol-associated bacterial pneumonia is essentially unknown. We have previously shown that indole supplementation mitigates increases in pulmonary bacterial burden and improves pulmonary NK cell recruitment in alcohol-fed mice, which were dependent on aryl hydrocarbon …

The crosstalk between clathrin-mediated endocytosis (CME) and the autophagy pathway has been reported in mammals; however, the interconnection of CME with autophagy has not been established in plants. Here, we report that the Arabidopsis CLATHRIN LIGHT CHAIN (CLC) subunit 2 and 3 double mutant, clc2-1 clc3-1, phenocopies Arabidopsis AUTOPHAGY-RELATED GENE (ATG) mutants in both autoimmunity and nutrient sensitivity. Accordingly, the autophagy pathway is significantly compromised in the clc2-1 clc3-1 mutant. Interestingly, multiple assays demonstrate that CLC2 directly interacts with ATG8h/ATG8i in a domain-specific manner. As expected, both GFP-ATG8h/GFP-ATG8i and CLC2-GFP are subjected to autophagic degradation, and degradation of GFP-ATG8h is …

Translational Potential Of Mouse Models Of Human Metabolic Disease, I Sadaf Farooqi, Yong Xu

Children’s Nutrition Research Center Staff Publications

Obesity causes significant morbidity and mortality globally. Research in the last three decades has delivered a step-change in our understanding of the fundamental mechanisms that regulate energy homeostasis, building on foundational discoveries in mouse models of metabolic disease. However, not all findings made in rodents have translated to humans, hampering drug discovery in this field. Here, we review how studies in mice and humans have informed our current framework for understanding energy homeostasis, discuss their challenges and limitations, and offer a perspective on how human studies may play an increasingly important role in the discovery of disease mechanisms and identification …
