Faculty, Staff and Student Publications

Purpose: The primary objective was to determine whether growth failure (GF) is associated with early recurrence in congenital diaphragmatic hernia (CDH). The secondary objective was to characterize the prevalence and severity of GF in CDH survivors.

Background: GF is common among CDH survivors, yet it is unclear how growth challenges affect overall morbidity, including hernia recurrence. CDH-specific nutritional guidelines include high calorie and protein targets during periods of acute illness but may benefit from clarifying the relationship between growth and adverse outcomes in this population.

Methods: This multicenter cohort study retrospectively analyzed prospectively collected data from the CDH Study Group …

A Treat-To-Target Approach For Obesity Management: A Post Hoc Analysis Of The Surmount-5 Trial., Carel W Le Roux, Luca Busetto, Louis Aronne, Deborah Bade Horn, Georgios K Dimitriadis, Beverly Falcon, Luis-Emilio Garcia-Perez, Elisa Gomez Valderas, Theresa Hunter Gibble, Cagri Senyucel, Julia P Dunn

Faculty, Staff and Student Publications

Introduction: With new advancements in obesity medicine, clarity on goals and expectations for successful disease management is limited. This post hoc analysis assessed application of proposed treat-to-target (TtT) thresholds for obesity to the outcome measures of SURMOUNT-5, which randomised participants with obesity to tirzepatide or semaglutide.

Methods: The proportion of participants in each treatment group reaching proposed TtT thresholds for waist to height ratio (WHtR) < 0.53, body mass index (BMI) < 27 kg/m2, or a combination was evaluated. The associations between the thresholds and achieving low disease activity to remission (meeting goals for at least four of five defined cardiometabolic risk parameters) and normalisation or improvement in SF-36v2 physical component score (PCS) from baseline to week 72 were explored.

Results: About 23.1%-33.9% of participants treated with tirzepatide and 14.2%-20.7% treated with semaglutide reached the TtT thresholds, with greater weight reduction than the overall population. About 77% of participants who reached WHtR < 0.53 achieved low disease activity to remission, with an odds ratio of 2.31 (p < 0.001) compared to those who did not reach this target. The BMI threshold was not statistically associated with the assessed outcomes for SF-36v2 PCS.

Conclusion: In this …

Children’s Nutrition Research Center Staff Publications

During weaning, the transition to solid food diversifies the gut microbiome, triggering a programmed immune response critical for long-lasting mucosal immunity. Previous work showed that the gut microbiome mediates epigenetic development in intestinal stem cells (ISCs) during suckling, but what happens during weaning is unclear. Here, genome-wide profiling revealed that weaning-driven microbiome changes shape the DNA methylome and transcriptome of murine ISCs in an IFNγ-dependent manner. Specifically, we observe demethylation of enhancer elements essential for MHC class II genes, which results in a transcriptional memory that persists through differentiation into adulthood. IFNγ blockade, or low-dose penicillin to target Gram-positive bacteria, …

Tfeb Degradation Is Regulated By An Ikk/Β-Trcp2 Phosphorylation-Ubiquitination Cascade, Yan Xiong, Jaiprakash Sharma, Meggie N Young, Wen Xiong, Ali Jazayeri, Karl F Poncha, Ma Xenia G Ilagan, Qing Wang, Bei Gao, Hui Zheng, Nicolas L Young, Marco Sardiello

Center on Aging Staff Publications

Transcription factor EB (TFEB) is a master regulator of lysosomal biogenesis and cellular clearance pathways. TFEB activity is tightly controlled by multiple post-translational mechanisms, but the exact molecular mechanism controlling its stability has remained elusive. Here, we identify the IκB kinase (IKK) complex as a key regulator of TFEB protein stability through a phosphorylation-ubiquitination cascade. A high-content kinase inhibitor screen reveals that IKK inhibition increases TFEB protein levels, and genetic ablation of IKK components increases TFEB stability, upregulates lysosomal genes, and enhances lysosomal biogenesis and degradative capacity. Mechanistically, we show that IKK phosphorylates TFEB on a cluster of serine residues …

Background:

Sorting Nexin 27 (SNX27), a key regulator of synaptic receptor trafficking and endosomal recycling, has been implicated in maintaining synaptic homeostasis and cognitive function. To date, variants in SNX27 have been reported in a small number of patients across three publications with severe neurodevelopmental phenotypes. However, the genetic and functional landscape of SNX27-related disorders remains poorly understood, and further evidence is needed to confirm its association with disease and to better delineate the associated phenotype.

Methods and Results:

Plant-Based Dietary Patterns Are Associated With Slower Epigenetic Aging, Hyunju Kim, Christina A Castellani, Jiantao Ma, Alexis C Wood, Audrey Ting, Morgan E Grams, Bing Yu, Kelly Ruggles, James S Floyd, Dan E Arking, Casey M Rebholz

Faculty, Staff and Students Publications

Greater adherence to plant-based diets is associated with health benefits. Dietary intake can modify DNA methylation patterns, but it is unknown whether plant-based diets in a largely non-vegetarian population are associated with DNA methylation-based epigenetic aging measures. We examined the associations between 4 different types of plant-based diets indices (PDI) [overall PDI, provegetarian diet, healthy PDI, and unhealthy PDI] and epigenetic aging. We used data from the Atherosclerosis Risk in Communities (ARIC) Study (N=2,810) and National Health and Nutrition Examination Survey (NHANES, N=2,056). PDIs negatively scored higher intake of animal products and positively scored higher intake of all or selected …

Endometriosis is a chronic gynecological disorder marked by the growth of endometrial-like tissue outside the uterus, often leading to pelvic pain, inflammation, and infertility. Despite its global prevalence, diagnosis remains delayed, and effective non-surgical treatments are lacking. While recent transcriptomic studies have identified mRNA transcript changes in ectopic lesions, the contribution of alternative pre-mRNA splicing, a key posttranscriptional regulatory layer, remains largely unknown. In this study, we performed a comprehensive analysis of alternative splicing (AS) events in endometriotic lesions using transcriptomic data. We uncovered distinct alterations in alternative splicing events are associated with endometriosis, highlighting a previously underappreciated layer of …

We experienced a 45-year-old male with ADPKD who developed spontaneous retroperitoneal hemorrhages with hypertension in the right subcapsular renal space without trauma. After his condition worsened with conservative management, he was treated by renal transarterial embolization (TAE). Over the next eight years, he experienced bilateral bleeding at three different sites and underwent repeated endovascular treatment with renal TAE to stop the bleeding. After the fourth occurrence, the patient underwent hemodialysis. Although renal cysts and urinary tract bleeding occur frequently in ADPKD, retroperitoneal hemorrhage is rare; however, TAE is both effective and a good way to preserve renal function.

Toward Scientific Rigor: Setting Standards For Indirect Calorimetry Analysis And Reporting, Elizabeth L Lieu, Mark A Herman, Sean M Hartig

Faculty, Staff and Students Publications

Indirect calorimetry determines energy expenditure by measuring respiratory gas exchange. The approach is based on the principle that nutrient metabolism consumes O2 and produces CO2 and water in predictable ratios that can be compared with heat production. Due to the impracticality and high cost of direct calorimetry, indirect calorimetry is the major approach for modern metabolic studies in preclinical models. Despite the broad adoption of this method in rodent phenotyping, the field has lacked standardized methods for analyzing, representing, and sharing these data, limiting scientific progress. The recent review in Nature Metabolism by the International Indirect Calorimetry Consensus Committee (IICCC) …

The Role Of Top-Down Appetite Self-Regulation In The Development Of Healthy Eating Behaviors Among Children: A Narrative Review And Socialization Framework, David J Bridgett, Sheryl O Hughes, Matthew Broussard, Daniela Mccourt, Christina M Croce, Jennifer O Fisher

Faculty, Staff and Students Publications

Appetite self-regulation (ASR) among children is thought to have a fundamental role in shaping the development of healthy eating behaviors, dietary intake, and growth during childhood. Parallel to developmental frameworks for understanding "general" self-regulation among children, ASR has been described as involving children's use of "top-down" cognitive processes to moderate "bottom-up" biological drives around food approach and avoidance in the interest of achieving desired eating behaviors or outcomes. Whereas bottom-up ASR processes during early childhood are well characterized, particularly in the context of dysregulation and obesity risk, the role of top-down ASR processes in the development of healthy eating behaviors …
