Effect of resistance spot welding aerosols on the mRNA expression of olfactory marker protein and dopaminergic markers in the olfactory bulb (OB). Rats were exposed to LM or HM aerosols (25 mg/m3 × 4 h/day) by whole-body inhalation for 13 days. At 1-day post-exposure, the mRNA expression of olfactory marker protein (Omp), tyrosine hydroxylase (Th), glial fibrillary acidic protein (Gfap), dopamine receptors 1, 2, 3 and 5 (Drd1, Drd2, Drd3 and Drd5), dopamine transporter (Slc6a3/Dat), vesicular monoamine transporter 2 (Slc18a2/Vmat2) and voltage-gated calcium channel member 1D (Cacna1d/Cav1.3) were assayed by TaqMan real-time PCR. Following normalization to the endogenous control beta actin (Actb), the values are expressed as fold change from air-exposed controls. Graphical representations are mean ±SE (n=4/group). *Indicates significant change from corresponding air-exposed control (p<0.05). #Indicates significantly different from LM-exposed group.
