dc.description.abstractThe hormone leptin is produced by mature adipocytes and plays an important role in regulating food intake and energy metabolism through its interaction with the leptin receptor. In addition to roles in obesity and obesity-related diseases, leptin has been reported to affect the components and secretion of bile in leptin-deficient mice. Furthermore, gallbladder diseases such as cholelithiasis are known to be associated with serum leptin concentrations in humans. We hypothesized that the canine gallbladder is a source of leptin and that the leptin receptor may be localized in the gallbladder, where it plays a role in regulating the function of this organ. The aim of this study was to demonstrate the presence and expression patterns of leptin and its receptors in normal canine gallbladders using reverse transcriptase-PCR (RT-PCR) and immunohistochemistry. Clinically normal gallbladder tissue samples were obtained from four healthy beagle dogs with similar body condition scores. RT-PCR and sequencing of the amplified PCR products revealed the presence of leptin mRNA and its receptors in the gallbladder. Immunohistochemical investigations demonstrated the expression of leptin and its receptors in the luminal single columnar and tubuloalveolar glandular epithelial cells. In conclusion, the results of this study demonstrated the presence of leptin and its receptors in the gallbladders of dogs. Leptin and its receptor were both localized throughout the cytoplasm of luminal and glandular epithelial cells. These results suggested that the gallbladder is not only a source of leptin, but also a target of leptin though autocrine/paracrine mechanisms. The results of this study could increase the understanding of both the normal physiological functions of the gallbladder and the pathophysiological mechanisms of gallbladder diseases characterized by leptin system dysfunction.-
