Analysis of differential expression of lipid metabolism genes in atherosclerotic plaques in patients with coronary atherosclerosis

Aim. The goal of the study was to analyze the differential expression of lipid metabolism-related genes in the atherosclerotic plaques of different types in patients with coronary atherosclerosis.Material and Methods. The study was performed on the specimens of atherosclerotic plaques in 45-65-year-old patients with coronary atherosclerosis with stable exertional angina functional class II-IV without acute coronary syndrome. Coronary atherosclerosis was verified by coronary angiography. Atherosclerotic plaque tissue was sampled intraoperatively when indicated. Whole-genome sequencing of ribonucleic acid (RNA) was performed using the TruSeq RNA Sample Preparation Kit (Illumina, USA).Results. We analyzed the differences in the expression of 12 genes including LDLR, APOB, PCSK9, LDLRAP1, LIPA, STAP1, ABCA1, APOA1, APOE, LPL, SCARB1, and SREBF2 depending on the type of atherosclerotic plaques. The expression level of APOE gene was eight times higher in unstable atherosclerotic plaques of dystrophic-necrotic type (p
