A Detection of PAR4 mRNA in rat tissues by RPA. Tissue sources are given at the top and the size of the protected fragment is given on the left. (CM, central marker; LES, lower esophageal sphincter; IAS, internal anal sphincter; DRG, dorsal root ganglia). B The PAR4/actin ratio suggests that PAR4 is predominantly expressed in the esophagus, LES, and the stomach.
