| Abstract: | ABCA1 transporter is known to play important role in the cholesterol transport from peripheral tissues. However its contribution in atherosclerosis development remains not completely understood. Using Real Time PCR, a significant reduction of ABCA1 mRNA level in leukocytes of patients with atherosclerosis was determined when compared with controls. Mean ABCA1 expression levels in leukocytes for the group of patients and for the control group are 0.57 +/- 0.28 and 0.93 +/- 0.14 (p = 0.02). At the same time we detected a significant increase of ABCA1 mRNA level in macrophages of patients when compared with controls. Mean ABCA1 expression levels in macrophages for the group of patients and for the control group are 1.32 +/- 0.10 and 0.90 +/- 0.14 (p = 0.014). In summary, we suggest that expression level of ABCA1 gene may contribute to the development of atherosclerosis. |
