Changes of TNF-α, IL-1β and IL-18 levels in the skeletal muscle of cows measured with RT-PCR analysis. Our results showed that TNF-α, IL-1β and IL-18 were differently expressed in the three groups. (A) TNF-α levels were very low in young cows (Group C) and increasingly higher in adult to aged animals (** p < 0.01; *** p < 0.001 vs. control). (B) IL-1β levels were increasingly higher from young cows (Group C) to adult and aged animals (Group B and A, respectively) (* p < 0.05 vs. control). (C) IL-18 levels were very low in young cows (Group C) and increasingly higher in adult to aged animals (Group B and A, respectively) (* p < 0.05; *** p < 0.001 vs. control).
