Activation of AMPK pathway by menthol. (A) Western blotting assay for p-ULK1, ULK1, p-AMPK, and AMPK protein expression levels (n≥3). (B, C) Bar graphs indicate the quantitative results of the corresponding protein bands. The protein expression results were homogenized using β-actin as an internal reference. The values are presented as the means ± SEM (**p < 0.01, ***p < 0.001 and ****p < 0.0001).
