• Apolipoprotein A-V
• Large HDL particles
• Hypertriglyceridemia
• VLDL-TG

Aim: Mice lacking apolipoprotein A-V (apoA-V) displayed an increase in serum triglyceride (TG) levels; however, the correlation of apoA-V levels with TG levels in humans is controversial, and the exact mechanism by which apoA-V affects TG levels is unclear. The aim of the present study was to clarify the impact of apoA-V on the lipoprotein subclass profile in preadolescent children, which has not been studied.
Method: The study subjects were 178 (89 male, 89 female) 4th grade elementary school children (mean /- SD: 9.5 /- 0.5 years old). ApoA-V levels were determined by an enzyme-linked immunosorbent assay, and the lipid component of each lipoprotein fraction and their particle sizes were measured by HPLC.
Results: Levels of apoA-V showed no gender difference in preadolescent children, and were not affected by anthropometric variables. ApoA-V had a negative association with serum TG levels and TG levels in each lipoprotein fraction, and a positive association with HDL-C. In particular, apoA-V appears to contribute to the increase in cholesterol levels in the larger HDL fraction.
Conclusions: It was suggested that apoA-V is a potent modulator of HDL and VLDL components in preadolescent children.
