Abstract
Oxidized low-density lipoprotein (ox-LDL) plays a key role in the processes of atherogenesis, the major cause of myocardial infarction. Increased levels of ox-LDL relate to plaque instability in human coronary atherosclerotic lesions. Moreover, ox-LDL levels show a direct correlation to the severity of coronary syndromes. Most of these effects are mediated by the interaction of ox-LDL with its major receptor, named LOX-1, that is encoded by OLR1 gene. In the present study, we examined the prevalence of OLR1 gene polymorphisms, IVS4-14 A/G and IVS4-73 C/T, which regulate the expression of LOXIN, in patients with ischemic cerebrovascular diseases (ICVD). We studied 43 consecutive patients (males = 19; females = 24) aged 26 to 65 years. All the patients were from the same geographical area. They were affected by ICVD. The control group comprised 69 healthy blood donors, with age and sex comparable to those of the patients. The distribution of G/G genotype and A/G genotype was statistically significant between patients and controls (chi(2) = 5.87, p = 0.01 and chi(2) = 4.33, p = 0.04, respectively). These preliminary data would suggest that in ICVD patients the LOX-1 isoform that induces internalization of ox-LDL is more frequent a...Continue Reading
