[Expressions of atherosclerosis-related genes in aorta in young apoE/LDLR double knockout mice].

To systematically clarify the effects of apolipoprotein E (aopE) and low-density lipoprotein receptor (LDLR) gene mutant on hyperlipidemia, vascular inflammation impairment and pathogenesis of atherosclerosis (AS), total RNA was isolated from fresh aortas of young apoE/LDLR double knockout (apoE(-/-)/LDLR(-/-)) and wild type (WT) mice using TRIzol reagent. Then RNA was reversely transcribed to first-strand cDNA by reverse transcriptase for reverse transcription polymerase chain reaction (RT-PCR) and real-time RT-PCR. Primer pairs were designed using primer design software according to the gene sequences available in GenBank.
