FOXJ3, a novel tumor suppressor in neuroblastoma.

Neuroblastoma (NB) poses a significant challenge in pediatric cancer care due to its aggressive nature and poor prognosis. While advances have been made in clinical treatments, therapy resistance remains a tough hurdle in NB treatment. While much research has focused on identifying oncogenes in NB, there has been less emphasis on understanding tumor suppressors.

Targeting protein synthesis pathways in MYC-amplified medulloblastoma.

MYC is one of the most deregulated oncogenic transcription factors in human cancers. MYC amplification/or overexpression is most common in Group 3 medulloblastoma and is positively associated with poor prognosis. MYC is known to regulate the transcription of major components of protein synthesis (translation) machinery, leading to promoted rates of protein synthesis and tumorigenesis.

Metabolomic signature of pediatric diabetic ketoacidosis: key metabolites, pathways, and panels linked to clinical variables.

Background: Diabetic ketoacidosis (DKA) is a serious complication of type 1 diabetes (T1D), arising from relative insulin deficiency and leading to hyperglycemia, ketonemia, and metabolic acidosis. Early detection and treatment are essential to prevent severe outcomes. This pediatric case-control study utilized plasma metabolomics to explore metabolic alterations associated with DKA and to identify predictive metabolite patterns.

dCasMINI-mediated therapy rescues photoreceptors degeneration in a mouse model of retinitis pigmentosa.

Retinitis pigmentosa (RP) is characterized by degeneration of rod and cone photoreceptors that progresses to irreversible blindness. Now, there are no mutation-agnostic approaches to treat RP. Here, we utilized a single adeno-associated virus (AAV)-based CRISPR activation system to activate phosphodiesterase 6B (Pde6b) to mitigate the severe degeneration in mice.

MRI-Based Circumferential Strain in Boys with Early Duchenne Muscular Dystrophy Cardiomyopathy.

In boys with Duchenne muscular dystrophy (DMD), cardiomyopathy has become the primary cause of death. Although both positive late gadolinium enhancement (LGE) and reduced left ventricular ejection fraction (LVEF) are late findings in a DMD cohort, LV end-systolic circumferential strain at middle wall (E) serves as a biomarker for detecting early impairment in cardiac function associated with DMD. However, E derived from cine Displacement Encoding with Stimulated Echoes (DENSE) has not been quantified in boys with DMD.

Molecular convergence of risk variants for congenital heart defects leveraging a regulatory map of the human fetal heart.

Congenital heart defects (CHD) arise in part due to inherited genetic variants that alter genes and noncoding regulatory elements in the human genome. These variants are thought to act during fetal development to influence the formation of different heart structures. However, identifying the genes, pathways, and cell types that mediate these effects has been challenging due to the immense diversity of cell types involved in heart development as well as the superimposed complexities of interpreting noncoding sequences.

Itaconic acid ameliorates necrotizing enterocolitis through the TFEB-mediated autophagy-lysosomal pathway.

Excessive autophagy has been implicated in the pathogenesis of necrotizing enterocolitis (NEC), yet the molecular underpinnings of the autophagy-lysosomal pathway (ALP) in NEC are not well characterized. This study aimed to elucidate alterations within the ALP in NEC by employing RNA sequencing on intestinal tissues obtained from affected infants. Concurrently, we established animal and cellular models of NEC to assess the therapeutic efficacy of itaconic acid (ITA).

The Study of Small RNA Sequencing from Biological Samples (miRNA-seq).

Small RNA sequencing (sRNA-seq) has greatly transformed the study of molecular biology by allowing thorough analysis of several types of short RNA molecules, such as microRNAs (miRNAs), small interfering RNAs (siRNAs), and piwi-interacting RNAs (piRNAs). This chapter presents a comprehensive methodology for conducting miRNA -seq on biological materials. The text introduces the principles and uses of miRNA-seq, emphasizing its importance in gene regulation, disease processes, and therapeutic interventions.

Proteins in scalp hair of preschool children.

Background: (1)Early childhood experiences have long-lasting effects on subsequent mental and physical health, education, and employment. Measurement of these effects relies on insensitive behavioral signs, subjective assessments by adult observers, neuroimaging or neurophysiological studies, or retrospective epidemiologic outcomes. Despite intensive search, the underlying mechanisms for these long-term changes in development and health status remain unknown.

Perceptions and Experiences of Universal School Meals in California: Qualitative Insights From School Food Authorities on Participation, Stigma, and Operational Benefits and Challenges.

Background: Universal school meals (USM) aim to eliminate barriers to school meal access by providing free meals to all students regardless of family income. During the COVID-19 pandemic, US Department of Agriculture waivers allowed schools nationwide to offer meals free of charge to all students. Although USM have demonstrated positive effects on student health and participation, limited research has focused on the perspectives of the foodservice directors (FSDs) who manage them.

Gynostemma pentaphyllum saponins shield mice from peanut allergy by modulation of gut microbiota: A novel approach for peanut allergy management.

Background: Food allergies, particularly peanut (PN) allergies, are a growing concern, with fatal anaphylaxis incidents often reported. While palforzia is the sole FDA-approved drug for managing PN allergies, it is not universally effective.

Purpose: This study aimed to investigate the potential of Gynostemma pentaphyllum saponins (GpS) as a novel therapeutic agent for PN allergy through modulation of gut microbiota, addressing the limitations of current treatments.

Validation of a Food Frequency Questionnaire: VioScreen-Allergy.

Modeling Epithelial Homeostasis and Perturbation in Three-Dimensional Human Esophageal Organoids.

Esophageal organoids from a variety of pathologies including cancer are grown in Advanced Dulbecco's Modified Eagle Medium-Nutrient Mixture F12 (hereafter ADF). However, the currently available ADF-based formulations are suboptimal for normal human esophageal organoids, limiting the ability to compare normal esophageal organoids with those representing a given disease state. We have utilized immortalized normal human esophageal epithelial cell (keratinocyte) lines EPC1 and EPC2 and endoscopic normal esophageal biopsies to generate three-dimensional (3D) organoids.

Adaptive integration of history variables in constrained mixture models for organ-scale growth and remodeling.

In the last decades, many computational models have been developed to predict soft tissue growth and remodeling (G&R). The constrained mixture theory describes fundamental mechanobiological processes in soft tissue G&R and has been widely adopted in cardiovascular models of G&R. However, even after two decades of work, large organ-scale models are rare, mainly due to high computational costs (model evaluation and memory consumption), especially in long-range simulations.
