Background
Glucagon-like peptide-1 (GLP-1) analogues regulate glucose homeostasis and have anti-inflammatory properties, but cause gastrointestinal side effects. The fibroblast growth factor 21 (FGF21) is a hormonal regulator of lipid and glucose metabolism that has poor pharmacokinetic properties, including a short half-life. To overcome these limitations, we investigated the effect of a low-dose combination of a GLP-1 analogue and FGF21 on atherosclerosis-related molecular pathways.
Methods
C57BL/6J mice were fed a high-fat diet for 30 weeks followed by an atherogenic diet for 10 weeks and were divided into four groups: control (saline), liraglutide (0.3 mg/kg/day), FGF21 (5 mg/kg/day), and low-dose combination treatment with liraglutide (0.1 mg/kg/day) and FGF21 (2.5 mg/kg/day) (n=6/group) for 6 weeks. The effects of each treatment on various atherogenesisrelated pathways were assessed.
Results
Liraglutide, FGF21, and their low-dose combination significantly reduced atheromatous plaque in aorta, decreased weight, glucose, and leptin levels, and increased adiponectin levels. The combination treatment upregulated the hepatic uncoupling protein-1 (UCP1) and Akt1 mRNAs compared with controls. Matric mentalloproteinase-9 (MMP-9), monocyte chemoattractant protein-1 (MCP-1), and intercellular adhesion molecule-1 (ICAM-1) were downregulated and phosphorylated Akt (p-Akt) and phosphorylated extracellular signal-regulated kinase (p-ERK) were upregulated in liver of the liraglutide-alone and combination-treatment groups. The combination therapy also significantly decreased the proliferation of vascular smooth muscle cells. Caspase-3 was increased, whereas MMP-9, ICAM-1, p-Akt, and p-ERK1/2 were downregulated in the liraglutide-alone and combination-treatment groups.
Conclusion
Administration of a low-dose GLP-1 analogue and FGF21 combination exerts beneficial effects on critical pathways related to atherosclerosis, suggesting the synergism of the two compounds.

Abstract PDF: BACKGROUND
Identifying the donor and isolation-related factors during the islet isolation would be greatly helpful to improve the result of human islet isolation for successful clinical islet transplantation. METHODS: Sixty-nine pancreata from cadaveric donors were isolated with standard protocol and analyzed to identify the donor factors and isolation variables for successful isolation. Islet isolations recovered > or = 100,000 Islet Equivalent (IEQ, n=53) were compared to islet mass less than 100,000 IEQ (n=16). RESULTS: The mean islet recovery was 216.0 x 10(3) +/- 173.7 x 10(3) (IEQ) before purification and 130.6 x 10(3) +/- 140.2 x 10(3) (IEQ) after purification. Mean purity was 54 +/- 31%. Mean age of donor was 31.2 +/- 13.2 year and mean cold ischemic time was 6.9 +/- 6.2 hour. Quality of isolated islets was acceptable in terms of bacterial culture, viability and secretory function in vitro and in vivo. In univariate analysis on successful isolation, status of pancreas was the only significant factor and sex, duration of collagenase expansion and digestion time were marginal factors. Stepwise multivariate logistic regression analysis showed donor sex, status of pancreas and digestion time were significant factors for the successful islet isolation. CONCLUSION: This study confirms some donor factors and variables in isolation process can influence the ability to obtain the successful isolation of human islet. Enough experiences and pertinent review of donor and isolation factors can make islet isolation successful, supporting the clinical islet transplantation without spending of cost.
