Hypertriglyceridemia is a risk factor for cardiovascular disease, and clinical practice guidelines advocate treatment to reduce triglyceride (TG) levels. In Japan, an EPA-E (eicosapentaenoic acid-ethyl ester) product has been used clinically for treating dyslipidemia. We investigated the TG-lowering effects of TAK-085 (EPA-E + docosahexaenoic acid-ethyl ester) in comparison with EPA-E in Japanese ...

We identify an Arabidopsis pyridoxal-phosphate-dependent aminotransferase, VAS1, whose loss-of-function simultaneously increases amounts of the phytohormone auxin and the ethylene precursor 1-aminocyclopropane-1-carboxylate. VAS1 uses the ethylene biosynthetic intermediate methionine as an amino donor and the auxin biosynthetic intermediate indole-3-pyruvic acid as an amino acceptor to produce L-tryptophan and 2-oxo-4-methylthiobutyric acid. Our ...
