Figure 6From: Glutamine starvation enhances PCV2 replication via the phosphorylation of p38 MAPK, as promoted by reducing glutathione levels Glutamine starvation increases the phosphorylation of p38 MAPK via the reduced GSH synthesis. PK-15 cells lysates were extracted to measure the protein levels of p38 phosphorylation by Western blot after incubation for 72 h in the absence of glutamine or in the presence of glutamine and BSO (A and B). Values are shown as mean ± SD from three independent experiments. Asterisks indicate groups statistically significantly different from control by a 1-way ANOVA followed by least-significant difference test (**P < 0.01).Back to article page
