RT-PCR for PTHLH and PTHR1 in the normal gastric mucosa samples. a The RT-PCR analysis revealed expression of PTHLH and PTHR1 in the normal gastric mucosa. Lane 1 negative controls. Lane 2 samples from endoscopy for PTHLH. Lane 3 samples from surgery for PTHLH. Lane 4 samples from enterology for PTHR1. Lane 5 samples from surgery for PTHR1. Lane 6 and 7 positive controls for PTHLH and PTHR1, respectively. The results were normalized to β-actin. b An example of the results of PTHLH detected by qRT-PCR. β-actin was used as a control
