Recently, a team of researchers from China Agricultural University and the Institute of Subtropical Agriculture (ISA) of the Chinese Academy of Sciences revealed the role of HMB supplementation in liver injury.

Their findings were published in Oxidative Medicine and Cellular Longevity on April 2.

Using a lipopolysaccharide (LPS)-challenged piglet model, the researchers found that HMB supplementation ameliorated liver histomorphological abnormalities and restored the elevation of serum activities of aspartate aminotransferase and alkaline phosphatase (useful biochemical indicator of liver injury) induced by LPS challenge.

The results suggest that HMB exerted beneficial effects on the inhibition of liver injury.

Upon further investigation, they found that the mechanism might be associated with improved hepatic energy metabolism via regulating AMP-activated protein kinase signaling pathway and reduced liver inflammation via modulating toll-like receptor 4 and nucleotide-binding oligomerization domain protein signaling pathways.

These findings may help developing new interventions to ameliorate liver injury and dysfunction in animals and humans with exposure to endotoxin.
