Article Abstract
Several studies have demonstrated that high protein diets improve glucose homeostasis. Nevertheless, the mechanisms underlying this effect remain elusive. This exploratory study aims to screen and compare the acute effects of dietary proteins from different sources on intestinal glucose absorption. Six dietary proteins from various sources were thus selected and digested thanks to the INFOGEST static gastrointestinal digestion protocol. The digested proteins were able to decrease intestinal glucose absorption and . Moreover, acute ingestion of casein and fish gelatin led to improved glucose tolerance in Wistar rats without significant effect on insulin secretion. In parallel, GLUT2 mRNA expression in enterocytes was decreased following short-term incubation with some of the digested proteins. These results strengthen the evidence that digested protein-derived peptides and amino acids are key regulators of glucose homeostasis and highlight their role in intestinal glucose absorption.

Extracellular polysaccharides (EPS) from Pediococcus pentosaceus were obtained, followed by investigation of their structural and functional properties. Current results indicated the polysaccharides belonged to glucomannans, which mainly consisted of mannose and glucose with a molecular weight of 2248.71 kDa.

In this study, Cyprinus carpio nudus were exposed for 2 weeks to polyethylene microplastics (MPs) of two particle sizes (125 μm and 34 μm) at concentrations of 0, 40, 80, 160, 320, and 640 ppm. The experiment involved 11 treatment groups, each with triplicate tanks, and evaluated MPs accumulation in tissues, hematological profiles, plasma components, and antioxidant responses. Accumulation in the gill, intestine, and liver were quantified using Nile red staining and fluorescence microscopy, showing the highest accumulation in the intestine, followed by the gill and liver, with smaller MPs accumulated significantly more than larger MPs.

The farnesoid X receptor (FXR), expressed in the liver and in the small intestine, is a key regulator of glucose and lipid metabolism. Its pharmacological modulation is explored as a potential treatment for obesity-related metabolic impairments. To develop effective pharmacological interventions, it is crucial to differentiate the individual contributions of intestinal and hepatic FXR to lipid metabolism.

Introduction: Glucose transporter (GLUT) research in parasitic nematodes focuses on identifying and characterizing developmentally regulated isoforms, elucidating their regulatory and structural properties, and evaluating their potential as drug targets. While glucose transport mechanisms have been well characterized in the free-living nematode , data on parasitic species remain limited. s.
