| pubmed-article:12655575 | pubmed:abstractText | Elevated plasma triglyceride and nonesterified fatty acid concentrations may cause insulin resistance. Lipoprotein lipase (LPL) is a rate-determining enzyme in lipid metabolism. To investigate the role of the LPL gene in Chinese patients with hypertriglyceridemic type 2 diabetes, 277 patients with type 2 diabetes and 241 healthy control subjects were recruited and screened for sequence changes in the LPL gene by PCR, SSCP, restriction analysis and direct DNA sequencing. Ten mutations were identified: four missense mutations, Ala71Thr, Val181Ile, Gly188Glu and Glu242Lys; one nonsense mutation Ser447Ter; and five silent mutations. Ser447Ter was found in both patients and controls with no significant difference in frequency. The four missense mutations were located in the highly conserved exon 3, 5, and 6 regions and in highly conserved amino acid sites. They led to reduced LPL mass and enzyme activities in both post-heparin plasma and in vitro expression. The modeled structures displayed major differences between the mutant and wildtype molecules. These results indicated that the four missense mutations lead to LPL deficiency and subsequent hypertriglyceridemia. Based on our study and published data, a putative pathogenic pathway was suggested: LPL enzyme deficiency causes elevated plasma triglyceride level and subsequent insulin resistance; both increased free fatty acids and insulin resistance promote gluconeogenesis and hyperglycaemia, a vicious circle leading to type 2 diabetes. | lld:pubmed |
