چکیده

This review describes theories of human atherogenesis and experimental results evaluating gene or protein expression in the pigeon model for spontaneous atherosclerosis. The spontane‐ ous disease in the pigeon differentiates from other animal models that require manipulation (genetic, nutritional, environmental) to induce the disease state. Both susceptible and resistant pigeons have been studied with susceptibility being inherited as an autosomal recessive trait. The aims are to present the pigeon data in comparison to current theories of the human disease.

Atherosclerosis-susceptible and atherosclerosis-resistant pigeon aortic cells express different genes in vivo.

Spontaneous atherosclerosis in the White Carneau (WC-As) pigeon is inherited as a single gene disorder, and its progression closely mirrors the human disease. Representational difference analysis and microarray were used to identify genes that were differentially expressed between the susceptible WC-As and resistant Show Racer (SR-Ar) aortic tissue. The RNA extracted from 1-d-old squab aortas w...

Metabolism of low density lipoproteins by pigeon skin fibroblasts and aortic smooth muscle cells. Comparison of cells from atherosclerosis-susceptible and atherosclerosis-resistant pigeons.

Aortic smooth muscle cells from atherosclerosis-susceptible White Carneau (WC) pigeons lack a functional low density lipoprotein (LDL) receptor pathway. The purpose of the present study was to determine if atherosclerosis-resistant Show Racer pigeons (SR) shared this lack of an LDL receptor pathway and if LDL from normal and hypercholesterolemic pigeons were metabolized similarly. The amount of...

Effect of Oxidized Low Density Lipoprotein on the Expression of Runx2 and SPARC Genes in Vascular Smooth Muscle Cells

Background: Vascular calcification is an important stage in atherosclerosis. During this stage, vascular smooth muscle cells (VSMC) synthesize many osteogenic factors such as osteonectin (encoded by SPARC). Oxidative stress plays a critical role in atherosclerosis progression, and its accumulation in the vascular wall stimulates the development of atherosclerosis and vascular calcification. The...

بررسی تاثیر اسیدالائیدیک بر بیان ژن استئونکتین در سلول‌های عضله‌ی صاف دیواره‌ی رگ‌ها

Background and Objective: Atheroma formation and progression of atherosclerosis are dependent on the expression of bone matrix proteins and regulatory factors such as osteonectin in the vessel walls. Studies have shown that consumption of Trans fatty acids increase risk of cardiovascular diseases. In this study, the effect of elaidic acid on osteonectin gene expression as one of the vascular ca...

Response to sex hormones differs in atherosclerosis-susceptible and -resistant mice.

Genetic factors that determine the degree of susceptibility to atherosclerosis may also influence the effects of estrogens and progestins in arterial vessel disease. We examined and compared estrogen receptor (ER) and progesterone receptor (PR) expression and the effects of 17beta-estradiol (E2) and progesterone (P) on collagen synthesis and matrix metalloproteinase (MMP) activities in the aort...
