By using the pancreatic form of human GLP-1R cDNA as a probe, Wei et al. (26) in 1995 detected mRNA from human kidneys, and in 2007, Körner et al. (3) investigated nonneoplastic human tissues resected along with tumor tissue from multiple samples (n = 209) and analyzed the GLP-1R expression in several organs by receptor autoradiography. This evidence concerns the gene GLP1R and neoplasm.
