Introduction. The functions of CD36 membrane receptor include removal of oxidized low-density lipoproteins from plasma. The aim of our study was to search association between the IVS3-6 C allele and hypercholesterolemia in overweight children. Material and Methods. The study groups comprised 55 Caucasian children with (33) and without hypercholesterolemia (22). Amplicons of exon 4 including fragments of introns 3 and 4 were studied using denaturing high-performance liquid chromatography (DHPLC). Results. Polymorphism detected by DHPLC was single nucleotide substitution in intron 3 (IVS3-6 T/C - rs3173798). The IVS3-6 T/C polymorphism is located in the region encoding the oxidized LDL binding domain, at a conserved splice site. Total serum cholesterol concentrations were significantly lower in the IVS3-6 TC heterozygotes than in the TT patients. Furthermore we found tendency (p=0.06) to lower LDL-cholesterol level in IVS3-6 TC heterozygotes than in wild-type homozygotes. Conclusion. The results of our preliminary study suggest that the IVS3-6 C allele of CD36 rs3173798 polymorphism may be associated with lower serum total and LDL-cholesterol in overweight children diagnosed with hypercholesterolemia.

    Algal polysaccharides such as carrageenan are good sources of dietary fibre. Previous studies have shown that carrageenan has hypoglycemic effects, but its cholesterol and lipid-lowering effects have yet to be demonstrated. In this study, carrageenan was incorporated into 4 food items, then fed...
