This disease is characterized by steatosis, cholestasis, and elevated liver stress markers. Continuous PN induces hepatic injury through mechanisms including insulin resistance, lipotoxicity, systemic inflammation, and oxidative stress. Infusion cycling is known to ameliorate clinical markers of liver injury, but metabolic underpinnings have not been thoroughly investigated. Therefore, we modeled PN-induced liver injury in mice to investigate how differential infusion patterns impacted hepatic metabolism. Intermittent infusions protected against increased circulating alanine aminotransferase levels and improved histopathology to more closely resemble chow controls. Transcriptomic analyses revealed 804 differentially expressed genes between PN groups, highlighting pathways related to peroxisome proliferator-activated receptor signaling, fatty acid metabolism, and peroxisomes. Relative to the continuous group, intermittent PN infusion specifically downregulated <i>Acaa1b</i>, <i>Aldh3a2</i>, <i>Inmt</i>, and <i>Acot4</i>; transcripts involved in peroxisomal lipid oxidation, dicarboxylic acid synthesis, and one-carbon metabolism. This study suggests that infusion cycling may attenuate metabolic burden induced by alternate lipid oxidation pathways. Future work can therapeutically leverage these metabolic pathways to deepen our understanding of PNALD/IFALD and guide PN treatments to improve patient outcomes.<b>NEW & NOTEWORTHY</b> This work demonstrated that the infusion schedule, independent of nutrient and caloric concentration, is a modulator of hepatic lipid metabolism in a novel murine model of parenteral nutrition. This cyclic infusion paradigm attenuated transcripts involved in microsomal and peroxisomal lipid oxidation, which were upregulated in the continuous infusion group. These data support the clinical use of cyclic infusion to improve hepatic parameters known to be adversely affected by parenteral nutrition.</p>","PeriodicalId":7725,"journal":{"name":"American journal of physiology.

The semipermeable nature of the mucus layer limits bacterial interactions with the epithelium while allowing nutrient absorption. Goblet cells (GCs) are specialized epithelial cells with a classical role to synthesize and secrete mucus to maintain the mucus layer. Emerging research has revealed the diverse nature of GC functions, including their interaction with the immune system through goblet cell-associated antigen passages to promote tolerance to dietary and bacterial antigens. Dysfunction of GCs or the mucus layer leaves the epithelium vulnerable to infection and is commonly associated with digestive disease. As such, there is a growing appreciation for the importance of GCs and the mucus layer to regulate mucosal homeostasis and protect against disease. Long-standing anatomical and pharmacological evidence indicates that the nervous system is a key regulator of GC function. However, the relative contribution from each division of the nervous system to the control of GC function is poorly defined. This is partly due to conflicting evidence from the literature and differences in experimental methods used. Furthermore, whether neurotransmitters influence GC functions and the associated mucus barrier directly or via indirect mechanisms, such as enhanced fluid secretion, remains unclear. The emergence of highly specific genetic approaches provides new opportunities to examine how specific nerve types can influence GC function. In this review, we consolidate the literature to date, with a focus on the stomach and lower gastrointestinal tract, and outline how current technologies may be useful to progress our fundamental understanding of neural-GC control.</p>","PeriodicalId":7725,"journal":{"name":"American journal of physiology.

There is no therapy to reduce ZAAT accumulation and restore proteostasis. Pioglitazone activates AMP-activated protein kinase (AMPK), enhance autophagy, and modulate ER stress responses, suggesting a potential effect on ZAAT clearance. Our objective is to examine whether pioglitazone can protect against AATD-mediated liver disease. <b>Methods:</b> Huh7.5 cells expressing ZAAT (HuhZ) and Pi*Z transgenic mice were used to investigate pioglitazone treatment on hepatic ZAAT accumulation, autophagy activation, and AMPK signaling. Histological, molecular, and metabolic analyses were conducted to assess changes in ZAAT content, autophagy markers, AMPK phosphorylation, and proteostasis. <b>Results:</b> Pioglitazone significantly reduced intracellular ZAAT and decreased lipid droplet accumulation in HuhZ cells. Pioglitazone markedly lowered hepatic ZAAT content in Pi*Z mice, suggesting enhanced degradation. This reduction was mediated through the AMPK pathway, indicated by increased phosphorylation of AMPK and ULK1. Pioglitazone induced autophagy, shown by decreased p62 and increased ATG5 and LC3B-II. This is indicative of enhanced autophagy. Although total hepatic AAT levels were reduced, PASD-positive ZAAT aggregates exhibited only a downward trend, suggesting these may be more resistant to clearance. <b>Conclusion:</b> These findings demonstrate pioglitazone reduces hepatic ZAAT accumulation by activating AMPK and inducing autophagy in AATD-associated liver disease, supporting its potential for therapeutic repurposing. As pioglitazone is FDA-approved with benefits for metabolic liver health, further studies are warranted to evaluate efficacy in restoring proteostasis and reducing hepatic ZAAT.</p>","PeriodicalId":7725,"journal":{"name":"American journal of physiology.

To gain insight into the cholangiocyte signaling mechanisms contributing to these pathophysiologic processes, mice were fed a DDC diet for 10 days to induce liver injury and then switched to a chow diet to permit recovery, designated as R days. Profiling of isolated intrahepatic leukocytes by mass spectrometry revealed an abundant CX3CR1⁺ macrophage population on the DDC diet which declined during the recovery period. This observation was confirmed using <i>Cx3cr1</i>^GFP mice. Next, cholangiocytes were isolated from control, DDC, and R15 mice, and RNA-seq performed. Cholangiocyte CX3CL1 expression, the cognate ligand for CX3CR1, increased in DDC fed mice and returned to basal values by R15, implicating cholangiocytes in CX3CR1⁺ macrophage recruitment. Ingenuity pathway analysis (IPA) of the RNAseq data revealed upregulation of the pathogen induced cytokine storm pathway in cholangiocytes activated from DDC fed mice, and resolution of this pathway in R15 isolated cholangiocytes. SCENIC regulon analysis identified that NF-Y, a transcription factor complex, was activated only on the DDC diet, but not in control or R15 mice. Finally, siRNA targeted suppression of NF-YA in normal human cholangiocytes (NHC) reduced cholangiocyte expression of the profibrogenic ligand <i>TGFβ1</i>.

In piglets, early weaning profoundly disrupts GI development, altering the intestinal epithelial barrier, reshaping immune function, and inducing lasting changes in the enteric nervous system. Despite these adverse outcomes, the early molecular mechanisms that initiate these alterations and set the gut on a divergent developmental trajectory remain poorly understood. Here, we utilized RNA sequencing and bioinformatic analyses to delineate early transcriptional changes in the jejunal mucosa of early-weaned male castrates compared to unweaned littermates. Ex vivo Ussing chamber experiments validated functional changes associated with these transcriptional alterations. Weaning triggered rapid transcriptional shifts observable within 3 hours, including suppressed mitochondrial energy production and increased glucose transporter expression. Pathway analysis revealed upregulation of ion channel transport genes (KCN, SCN, TRP, SLC) and neurotransmitter receptors (cholinergic, dopaminergic, GABAergic, glutamatergic), indicating early neuronal adaptations. Functional assays confirmed enhanced SGLT-mediated glucose transport and neural-evoked secretory responses 24 hours post-weaning, supporting transcriptomic findings. These findings reveal previously unexamined early transcriptional and functional changes that may serve as inciting mechanisms altering gut trajectory during this critical developmental window, providing new insight into how psychosocial stress and early weaning contribute to long-term gut dysfunction, with broader implications for preterm birth, neonatal GI injury, and other early-life stressors that impact lifelong GI health.</p>","PeriodicalId":7725,"journal":{"name":"American journal of physiology.

Emerging evidence has identified bacterial lipopolysaccharides in the hippocampus of patients with Alzheimer's disease (AD), highlighting the intricate relationship between the gastrointestinal tract, gut microbiome, and the central and enteric nervous systems-commonly referred to as the \"microbiota-gut-brain axis.\" In this review, we explore the mechanisms by which the microbiota-gut-brain axis contributes to AD pathogenesis. We propose that sufficient levels of all-trans retinoic acid (ATRA), the bioactive form of vitamin A, enhance intestinal barrier integrity by upregulating tight junction proteins and modulating immune function through the induction of regulatory T-cell differentiation, thereby mitigating inflammation. Furthermore, dietary fiber complements this process by promoting the production of short-chain fatty acids, such as butyrate, via bacterial fermentation. Butyrate, in turn, acts as a histone deacetylase inhibitor, upregulating ATRA bioavailability by elevating aldehyde dehydrogenase gene expression. Our mechanistic framework is supported by the endotoxin hypothesis of AD, which maintains that the movement of infectious pathogens across the blood-brain barrier causes a vicious cycle of inflammation, a key factor of AD pathogenesis, leading to amyloid-β deposition, microglial activation, and CYP26A1-mediated ATRA degradation. Finally, we discuss microbiome-based therapeutic strategies and dietary interventions, including prebiotic compounds, probiotic bacteria, fecal microbiota transplantation, the Mediterranean-DASH Intervention for Neurodegenerative Delay (MIND) diet, and a combined approach featuring vitamins A/D and dietary fiber, as potential approaches to prevent progression to AD via the microbiota-gut-brain axis.</p>","PeriodicalId":7725,"journal":{"name":"American journal of physiology.
