Short‐term heat stress altered AP‐1 signaling in oxidative skeletal muscle. Relative protein abundance of SAPK/JNK, pSAPK/JNK and AP‐1 were measured in whole homogenate (A) and AP‐1 was measured in nuclear fraction (C) using western blot. Representative blots are included (B and D). Ponceau S stain (PS) was used as a loading control. * Indicates significant difference compared to TN control, P < 0.05. # Indicates significant difference compared to 2 h of heat stress, P < 0.05; T indicates time effect between the treatments, L indicates linear effect between the treatments Values are mean ± SE; n = 8/group.
