Differential expression of OR genes in the endoturbinates. We prepared mRNA from the four endoturbinates dissected from an adult rat. mRNA samples were used for RTqPCR (technical triplicates for each gene) for the same set of 77 OR genes. ΔΔCt values were expressed with respect to Hprt mRNA as internal reference and the control sample as external control as specified in [51]. Endoturbinate II', III and IV OR Ct values were normalized with respect to endoturbinate II OR Ct values, taken as a reference. The standard deviations are calculated from the triplicate values. Panel A is a control showing that Gapdh and Golf are expressed at similar levels in the four different endoturbinates. Panel B shows the Ct values for the OR genes that are more strongly expressed in endoturbinate II. Panel C shows OR genes with similar levels of expression in endoturbinates II and II'. In panel D, are shown OR genes more strongly expressed in endoturbinate II'; panel E presents OR genes more strongly expressed in endoturbinate III and, finally, panel F shows OR genes more strongly expressed in endoturbinate IV. On the x axis, OR gene family names follow gene names.
