Relationship of plasma apolipoprotein M with proprotein convertase subtilisin-kexin type 9 levels in non-diabetic subjects
Författare
Summary, in English
Purpose: Apolipoprotein M (apoM) retards atherosclerosis development in murine models, and may be regulated by pathways involved in LDL metabolism. Proprotein convertase subtilisin-kexin type 9 (PCSK9) plays a key role in LDL receptor processing. We determined the extent to which plasma apoM is related to PCSK9 levels in subjects with varying degrees of obesity. Methods: We sought correlations between plasma apoM and PCSK9, measured using recently developed ELISAs, in 79 non-diabetic subjects. Results: ApoM and PCSK9 levels were both correlated positively with total cholesterol, non-HDL cholesterol, LDL cholesterol and apoB (P < 0.05 to P < 0.001). ApoM correlated positively with PCSK9 in lean individuals (n = 37, r = 0.337, P = 0.041), but not in overweight subjects (n = 32, r = 0.125, P = 0.50) and in obese subjects (n = 10, r = -0.055, P = 0.88). Conclusions: The PCSK9 pathway may contribute to plasma apoM regulation in humans. The influence of PCSK9 on circulating apoM appears to be modified by adiposity. (C) 2010 Elsevier Ireland Ltd.
