Data are presented as mean ± SEM, n = 6. Values in the same row with different superscript are significantly different (P < 0.05) by one-way ANOVA. P-values (P-RSV, P-Stress, or P-RSV × Stress) ≤ 0.05 indicates RSV, heat stress, or the interaction between heat stress and RSV. RSV, resveratrol; NT, normal temperature; HT, heat stress; FN, fibronectin; IL-1β, Interleukin-1β; IL-2, Interleukin-2; IL-4, Interleukin-4; TNF-α, tumor necrosis factor-α; IFN-γ, interferon γ.
