α-NETA down-regulates CMKLR1 mRNA expression in ileum and prevents body weight gains collaborating with ERK inhibitor PD98059 in turn to alleviate hepatic steatosis in HFD-induced obese mice but no impact on ileal mucosal integrity and steatohepatitis progression.

ABSTRACT:

Background

Studies on chemerin/chemokine-like receptor-1 have mainly focused on adipose and liver with the intestinal tissues largely overlooked. In this study conducted on obese mice, we have explored: 1) CMKLR1 expression in the ileums; 2) CMKLR1 inhibitor α-NETA on body weight and intestinal mucosa integrity hence the impact on hepatic steatosis and pathway involved.

Methods

Nineteen male C57BL/6 mice were randomly divided into five groups: normal diet group (ND), high-fat diet group (HFD), HFD + α-NETA group (NETA), HFD + PD98059 group (PD) and HFD + α-NETA + PD98059 group (NETA + PD). Mice were fed either with a chow diet or HFD for 12 weeks. At 12^th week, mice of ND were put on the diet as before; mice of NETA received daily treatments of α-NETA (30 mg/kg) v
