GPR107 and liver dysplastic nodule: The results showed that the expression level of GPR107 in DN group was low, accompanied by renal function impairment and a large amount of 24-h urinary protein.There was a significant negative correlation between the level of GPR107 and 24-h urinary protein and urea nitrogen, that is, the lower the expression level of GPR107, the more severe the renal function injury and the more urinary protein (Fig. 1c, d).
