Lactate transport and metabolism in rumen epithelial cells in SARA condition

Lactate, a main product of rumen microbial fermentation from dietary starch, has been recognised as an important mediator of rumen microbiota regulation in rumen acidosis. However, the mechanism of lactate transport and metabolism in the rumen remains unclear. This study aimed to evaluate the signif...

description Lactate, a main product of rumen microbial fermentation from dietary starch, has been recognised as an important mediator of rumen microbiota regulation in rumen acidosis. However, the mechanism of lactate transport and metabolism in the rumen remains unclear. This study aimed to evaluate the significance of the absorption, transport, and metabolism of lactic acid in the pH and LPS-induced subacute ruminal acidosis (SARA) model of rumen epithelial cells (RECs). In the current study, RECs were obtained from two adult Saanen goats (44.5 ± 4.6 kg BW) and using Lipopolysaccharide (LPS) and low pH to co-stimulate RECs to construct a microenvironment under SARA conditions, to further analyse the lactate transport and metabolism by RECs. The results showed that the LPS and low pH could significantly reduce cell viability by 29.36% (p < 0.05), induce inflammation in RECs, destroy tight junctions between RECs, and increase cell permeability. In addition, stimulation leads to changes in cellular metabolic activity and inhibits the expression of lactate transporters (p < 0.05), promoting an increased risk of lactate accumulation in the intracellular and intestinal lumen. This study hopefully provides a better understanding of lactate metabolic regulation and new perspectives for the nutritional prevention and treatment of SARA.HIGHLIGHTS Lactic acid is an important fermentation product in the rumen of ruminants, and its transport and metabolic regulation mechanisms are still unclear. To understand transport uptake in the rumen epithelium, a SARA model was therefore used. Low pH and high LPS trigger epithelial inflammation, increasing the risk of lactic acid entering the bloodstream.
