Expression of TRPV1, BDNF, trkB and CGRP mRNA in DRG cultures after NGF or BDNF treatment. (A) TRPV1, BDNF, trkB and CGRP mRNA expression after 100 ng/ml NGF treatment, once daily for 24-96 hours. (B) TRPV1, trkB and CGRP mRNA expression after 100 ng/ml BDNF treatment, once daily for 24-72 hours. Data are expressed as mean ± SEM, presented as percentage of basal (no drug treatment) levels, and were analyzed using one-way AVOVA followed by Tukey test. *p < 0.05, **p < 0.01; compared to corresponding basal groups (N = 5~8 per group).
