In addition to its effects in pancreas, it was reported that KO of ZnT8 in mice produced increased adiposity, manifestly through the control of serotonin (5-hydroxytryptamine) synthesis, underlining then a potential role of ZnT8 in control of obesity [177] and metabolic syndrome [332] and the importance of developing therapeutics targeting ZnT8 not only in diabetes. Here, SLC30A8 is linked to Obesity.
