Objective: This experiment was conducted to investigate whether asparagine (Asn) could improve liver energy status in weaning pigs when challenged with lipopolysaccharide.

Methods: Forty-eight weaned pigs (Duroc×Large White×Landrace, 8.12±0.

Stress causes intestinal inflammation and barrier dysfunction. Corticotrophin-releasing factor (CRF)/CRF receptor (CRFR) signaling pathway has been shown to be important for stress-induced intestinal mucosal alteration. L-Asparagine (ASN) is a powerful stimulator of ornithine decarboxylase and cell proliferation in a variety of cell types, including colonic cells.

Infection and inflammation can result in the rapid loss of muscle mass and myofibrillar proteins (muscle atrophy). In addition, aspartate (Asp) is necessary for protein synthesis in mammalian cells. We hypothesized that Asp could attenuate LPS-induced muscle atrophy in a piglet model.

Pro-inflammatory cytokines are critical in mechanisms of muscle atrophy. In addition, asparagine (Asn) is necessary for protein synthesis in mammalian cells. We hypothesised that Asn could attenuate lipopolysaccharide (LPS)-induced muscle atrophy in a piglet model.

Stress induces injury in intestinal barrier function in piglets. Long-chain n-3 PUFA have been shown to exhibit potential immunomodulatory and barrier protective effects in animal models and clinical trials. In addition, corticotropin-releasing hormone (CRH)/CRH receptor (CRHR) signalling pathways play an important role in stress-induced alterations of intestinal barrier function.

Purpose: This study was conducted to investigate whether aspartate (Asp) could alleviate Escherichia coli lipopolysaccharide (LPS)-induced intestinal injury by modulating intestine inflammatory response.

Methods: Twenty-four weaned piglets were divided into four treatments: (1) non-challenged control; (2) LPS-challenged control; (3) LPS + 0.5 % Asp; and (4) LPS + 1.

Article Synopsis
  • The intestine needs a lot of energy to stay healthy, and low energy can cause damage; Asparagine (Asn) can help provide that energy by being a building block for other amino acids.
  • In a study with piglets, those given Asn showed better intestinal structure and function, with improved growth metrics and enzyme activities after being exposed to a harmful bacterial substance.
  • Asn seems to support gut health and energy levels by enhancing certain metabolic pathways and reducing the activity of specific signaling proteins involved in energy balance.

Pro-inflammatory cytokines play a key role in many models of hepatic damage. In addition, asparagine (Asn) plays an important role in immune function. We aimed to investigate whether Asn could attenuate lipopolysaccharide (LPS)-induced liver damage.

Purpose: This study was conducted to investigate whether aspartate (Asp) could improve liver energy status in the lipopolysaccharide (LPS)-challenged pigs.

Methods: Twenty-four weaned pigs were assigned to four treatments: (1) nonchallenged control (control diet and saline-treated); (2) LPS-challenged control (the same control diet and LPS-challenged); (3) LPS + 0.5% Asp treatment (0.

Pro-inflammatory cytokines play a critical role in many models of liver injury. In addition, aspartate (Asp) plays an important role in many biological and physiological processes including liver physiology. We hypothesized that Asp could alleviate lipopolysaccharide (LPS)-induced liver injury.

The intestine has a high requirement for ATP to support its integrity, function and health, and thus, energy deficits in the intestinal mucosa may play a critical role in intestinal injury. Aspartate (Asp) is one of the major sources of ATP in mammalian enterocytes via mitochondrial oxidation. We hypothesized that dietary supplementation of Asp could attenuate lipopolysaccharide (LPS)-induced intestinal damage via modulation of intestinal energy status.
