Image of gel of RT-PCR for HO-1 ( left ) and β-actin ( right ) mRNA from nasal mucosa of guinea pigs. Sizes of PCR products are 370 bp(HO-1) and 240 bp(β-actin). Lanes 1–4 were products of HO-1 of normal, AR, Hemin, ZnPP groups, and lanes 6–9 were products of β-actin (housekeeping gene), and lane 5 was a DNA marker to mark the size of the PCR product(100 600 bp). There was an increase in HO-1 mRNA in AR group compared with control, and HO-1 mRNA increased after Hemin treated and decreased after ZnPP treated, whereas there was no change in β-actin mRNA.
