| Research Abstract |
In the present study, we analyzed sequence variations in pig homolog of candidate genes for human obesity in order to develop efficient gene markers that can be used to improve the fat deposition traits in pigs. The preproghrelin (GHRL), growth hormone secretagogue receptor (GHSR), leptin receptor (LEPR), and G-protein coupled receptor 120 (GPR120) genes were selected to study. The c.335C>A polymorphism in GHRL gene was not associated with intra-muscular fat and back fat thickness. However, previously reported c.2002C>T (now c.1987C>T) polymorphism in LEPR was significantly associated with back fat thickness in our study population, and thus, we confirmed that this polymorphism could be an effective gene marker. Furthermore, we have succeeded in developing a simple genotyping method for this polymorphism.
