Dietary Beta-Hydroxy Beta-Methyl Butyrate Supplementation Alleviates Liver Injury in Lipopolysaccharide-Challenged Piglets

Figure 5

The mRNA expression of proliferation cell nuclear antigen (PCNA), caspase-3, tumor necrosis factor-α (TNF-α), and heat shock protein 70 (HSP70) in the liver of piglets injected with LPS or saline. Values are means, with their standard errors represented by vertical bars (). a,bMean values with different letters were considered to be significantly different (). CON: control; HMB: β-hydroxy-β-methylbutyrate; LPS: lipopolysaccharide.
