Figure 4From: Treatment of trigeminal ganglion neurons in vitro with NGF, GDNF or BDNF: effects on neuronal survival, neurochemical properties and TRPV1-mediated neuropeptide secretionAssessment of TRPV1 mRNA levels by Realtime PCR. Levels of TRPV1 mRNA are depicted as fold change compared with no growth factor-treated cultures for each growth factor condition normalized to its corresponding GAPDH mRNA levels (n = 3).Back to article page
