Acylcarnitines are anticoagulants that inhibit factor Xa and are reduced in
venous thrombosis, based on metabolomics data

In many patients with deep vein thrombosis and pulmonary embolism (venous
thromboembolism, VTE), biomarkers or genetic risk factors have not been
identified. To discover novel plasma metabolites associated with VTE risk, we
employed liquid chromatography-mass spectrometry-based untargeted metabolomics,
which do not target any specific metabolites. Using the Scripps Venous Thrombosis
Registry population for a case-control study, we discovered that 10:1 and 16:1
acylcarnitines were low in plasmas of the VTE patient group compared with matched
controls, respectively. Data from targeted metabolomics studies showed that
several long-chain acylcarnitines (10:1, 12:0, 12:2, 18:1, and 18:2) were lower
in the VTE group. Clotting assays were used to evaluate a causal relationship for
low acylcarnitines in patients with VTE. Various acylcarnitines inhibited factor
Xa-initiated clotting. Inhibition of factor Xa by acylcarnitines was greater for
longer acyl chains. Mechanistic studies showed that 16:0 acylcarnitine had
anticoagulant activity in the absence of factor Va or phospholipids. Surface
plasmon resonance investigations revealed that 16:0 acylcarnitine was bound to
factor Xa and that binding did not require the ?-carboxy glutamic acid domain. In
summary, our study identified low plasma levels of acylcarnitines in patients
with VTE and showed that acylcarnitines have anticoagulant activity related to an
ability to bind and inhibit factor Xa.
