Expression analysis of the 30 most selectively expressed GPCRs in the human TG and DRG.

<p><b>A</b> The heatmap shows the 30 most selectively expressed GPCR transcripts in the TG in comparison with the DRG and reference tissues (brain, colon, liver, lung, s. muscle, and testis). Genes are ranked according to their selective expression in the TG (Quotient of the mean FPKM value (TG1-4) and the mean FPKM value for all reference tissues; only the transcripts detected in all four TG samples with FPKM >0.1 are taken into account). MRGPRs are the most selective GPCRs that have been detected. <b>B</b> Shown are the 30 most selectively expressed GPCRs in the DRG. Genes are ranked according to their selective expression in DRG. The ranking was calculated by the quotient of the FPKM value of DRG (FPKM >0.1) and the mean FPKM value for all reference tissues. GPR139 is the most specific GPCR followed by three MRGPRs, which have been selectively detected in the human DRG.
