BACKGROUND: Apolipoprotein A5 (ApoA5) is present in human serum at a very low concentration. We developed a new method to determine ApoA5 concentration in human serum, and to investigate the correlation between serum ApoA5 and the lipid profiles in healthy subjects, and to analyze whether the correlation was affected by gender. METHODS: All the subjects (total 92, male 50, female 42) were healthy subjects without any medication. Lipids were measured enzymatically. An ELISA performed by a couple of monoclonal antibodies was used to measure serum ApoA5. RESULTS: The average ApoA5 concentration was 182.7+/-104.7 ng/ml ranging from 5.4 to 455.6 ng/ml. Serum ApoA5 concentration was negatively correlated with TG in female (r=-0.496, P=0.001). In all subjects, ApoA5 concentration was positively correlated to HDL-C (r=0.453, P<0.001). This correlation was more predominant in female (r=0.617, P<0.001) than in male (r=0.289, P=0.042). ApoA5 concentration was negatively correlated to body mass index (BMI) with more significance in female than in male (r=-0.345, P=0.001 for all; r=-0.456, P=0.002 for female; r=-0.198, P=0.167 for male). CONCLUSIONS: The serum concentration of ApoA5 was very low. The concentration of ApoA5 was negatively correlated with TG and BMI, but positively correlated with HDL-C. The correlations were affected by gender.
