AIM: To study the effect of cholecystokinin octapeptide(CCK-8) on lipopolysaccharide (LPS)-stimulated pulmonary interstitial macrophage(IM) in vitro. METHODS: Pulmonary IM were isolated and cultured in the presence of LPS, CCK-8, proglumide(the antagonist of CCK receptors) and vehicle alone or together. The expression of mCD14 protein was assayed by flow cytometry, and sCD14 in the supernatant was analyzed semi-quantitatively by Western blot, and TNF-? in the supernatant was detected with ELISA. RESULTS: CCK-8, at concentrations from 10 -7 mol/L to 10 -6 mol/L inhibited significantly the expression of mCD14, the release of sCD14 and TNF-? to the supernatant up-regulated by LPS(1 mg/L). The effect of CCK-8 was inhibited by proglumide. CONCLUSION: CCK-8 modulated negatively several functions of LPS-stimulated pulmonary IM through CCK receptors, which may be one of the mechanisms for CCK-8 to alleviate the inflammation in lung tissues during endotoxemia.

OBJECTIVETo study the mechanism underlying the effect of the SOCS3 rs4969170 A/G alleles on the occurrence of insulin resistance (IR) in patients with chronic hepatitis C.

METHODSThe promoter region of the SOCS3 gene was amplified by PCR,and luciferase expression vectors were constructed and transfected into HepG2,Huh7 cell lines.The relative luciferase activity of each expression vector was assessed by the dual luciferase reporter gene assay system.Western blotting was used to detect SOCS3 protein expression in PBMCs from groups of patients with the rs4969170 AA and AG genotypes.The state of IR in eight patients was evaluated by determining their HOMA-IR.

RESULTSThe pGL3-A, PGL3-G and pGL3-control vectors showed significantly different luciferase expression in the HepG2 cells (0.121 00 ± 0.022 07,0.027 00+/-0.012 49 and 0.043 33 ± 0.005 51; F =48.068, P=0.001) and in the Huh7 cell lines (0.164 70 ± 0.007 10,0.027 33 ± 0.017 04 and 0.033 67 ± 0.014 98; F =115.137, P=0.001). The expression of SOCS3 protein was significantly higher in the rs4969170 AA genotype group than in the AG genotype group (1.22 ± 0.40 vs. 0.30 ± 0.19; t =4.149, P=0.006).The IR index of patients with the rs4969170 AA genotype and the AG genotype was 4.11 ± 2.62 and 1.47 ± 1.01 respectively.There were three patients with IR in the rs4969170 AA genotype group and one in the rs4969170 AG group. There was no statistically significant difference between the two genotype groups (t=1.881, P=0.109).

CONCLUSIONSThe SOCS3 rs4969170 A haplotype may enhance transcriptional activity of the gene promoter to regulate gene expression, thereby increasing intracellular SOCS3 protein level and ultimately interfering with insulin signaling and causing IR in patients with chronic hepatitis C.
