Protein levels of transient receptor potential ankyrin 1 (TRPA1) and calcitonin gene-related peptide (CGRP).

(A) Immunoblotting for TRPA1 and CGRP. (B, C) Optical density ratio of TRPA1 and CGRP protein relative to the control. Formaldehyde raised TRPA1 and CGRP protein levels. Menthol reduced TRPA1 and CGRP protein levels. The CGRP upregulation induced by formaldehyde was inhibited by PD98059. Data are expressed as the mean ± SD (n = 5, one-way analysis of variance followed by Dunnett’s T3 post hoc test). *P < 0.05, **P < 0.01, ***P < 0.001.
