Endocannabinoids, anandamide, and 2-arachidonoyl glycerol are involved in food intake and appetite. Although anandamide is now thought to be a ligand for vanilloid receptor, receptors that are targets of anandamide could play a similar role in eating behaviors and related disorders. This study therefore focused on the receptor, which is called G-protein-coupled receptor 55 (GPR55) that had recently been reported to have binding affinity for endocannabinoids. Functional analysis of the sole missense polymorphism, rs3749073 (Gly195Val) in the GPR55 gene was performed by detecting the phosphorylation level of extracellular signal-regulated kinase (ERK) in Chinese-Hamster-Ovary (CHO) cells engineered to express human GPR55. Val195 type GPR55 appeared to induce less phosphorylated ERK than Gly195 type GPR55 when CHO cells were treated with anandamide and lysophosphatidylinositol (LPI). An association between the functional Gly195Val polymorphism and anorexia nervosa was tested in a female Japanese population comprising 235 patients and 1244 controls. The Val195 allele and homozygote of the Val195 allele were more abundant in the group of patients diagnosed with anorexia nervosa (P = 0.023, Odds ratio = 1.31 (95% Cl = 1.03-1.37), P = 0.0048, OR = 2.41 (95% Cl = 1.34-4.34), respectively). In conclusion, the low-functioning Val195 allele of GPR55 appears to be a risk factor for anorexia nervosa.
