Creation of Apolipoprotein C-II (ApoC-II) Mutant Mice and Correction of Their Hypertriglyceridemia with an ApoC-II Mimetic Peptide.
Apolipoprotein C-II (apoC-II) is a cofactor for lipoprotein lipase, a plasma enzyme that hydrolyzes triglycerides (TGs). ApoC-II deficiency in humans results in hypertriglyceridemia. We used zinc finger nucleases to create Apoc2 mutant mice to investigate the use of C-II-a, a short apoC-II mimetic peptide, as a therapy for apoC-II deficiency. Mutant mice produced a form of apoC-II with an uncle...
متن کاملReduction of plasma triglycerides in apolipoprotein C-II transgenic mice overexpressing lipoprotein lipase in muscle.
LPL and its specific physiological activator, apolipoprotein C-II (apoC-II), regulate the hydrolysis of triglycerides (TGs) from circulating TG-rich lipoproteins. Previously, we developed a skeletal muscle-specific LPL transgenic mouse that had lower plasma TG levels. ApoC-II transgenic mice develop hypertriglyceridemia attributed to delayed clearance. To investigate whether overexpression of L...
متن کاملHuman apolipoprotein C-II: complete nucleic acid sequence of preapolipoprotein C-II.
Apolipoprotein (apo) C-II is a cofactor for lipoprotein lipase, the enzyme that catalyzes the hydrolysis of triglycerides on plasma triglyceride-rich lipoproteins. The complete coding sequence of apoC-II mRNA has been determined from an apoC-II clone isolated from a human liver cDNA library. A 17-base-long synthetic oligonucleotide based on amino acid residues 5-10 of apoC-II was utilized as a ...
متن کاملSpecificity of the lipid-binding domain of apoC-II for the substrates and products of lipolysis.
Functional similarities between colipase and apolipoprotein C-II (apoC-II) in activating lipases suggest that apoC-II may, like colipase, preferentially interact with interfaces containing the substrates and products of lipolysis. To test this hypothesis, the binding of a peptide comprising residues of the cofactor implicated in lipid binding, apolipoprotein C-II(13-56), and, to a lesser extent...
متن کاملOverexpression of apoC-I in apoE-null mice: severe hypertriglyceridemia due to inhibition of hepatic lipase.
Apolipoprotein C-I (apoC-I) has been proposed to act primarily via interference with apoE-mediated lipoprotein uptake. To define actions of apoC-I that are independent of apoE, we crossed a moderately overexpressing human apoC-I transgenic, which possesses a minimal phenotype in the WT background, with the apoE-null mouse. Surprisingly, apoE-null/C-I mice showed much more severe hyperlipidemia ...
