RESUMEN
Protein arginine methyltransferases (PRMTs) are widely found in eukaryotes and regulate gene expression and post-translational modifications. PRMT1-PRMT6 have important roles in the pathology of cardiovascular diseases (CVDs), including atherosclerosis, heart failure and myocardial hypertrophy. Although these enzymes are also closely associated with various CVDs, the mechanisms of the involvement of PRMTs in the regulation of CVD have remained largely elusive. PRMTs methylate arginine residues and other factors. The present review describes the roles of PRMT1-PRMT6 in CVD. Furthermore, the biological characteristics of PRMTs and mechanisms by which PRMTs regulate cholesterol metabolism are being introduced. This review aims to provide inspiration for cardiovascular drug research and offer clues for research on the pathogenesis of CVD.
RESUMEN
Soy sauce residue (SSR) is a valuable biological resource, which contains soy isoflavones (SIs) with antioxidant activity and can be used to scavenge radicals. Herein, MIL-100(Fe) was synthesized for the extraction of SIs from SSR. Under the optimal adsorption conditions, the adsorption capacity of MIL-100(Fe) for SIs was 51.81 mg/g, which could achieve a purity of 56.17% and a recovery of 93.8%. These results demonstrated MIL-100(Fe) possessed effective properties of adsorption and purification for SIs. The content of SIs in the purified product was 167 times than that of SSR. The purified total SIs had a good antioxidant activity. The established method had a good scavenging ability toward 2, 2-diphenyl-1-picrylhydrazyl, superoxide and hydroxyl radicals, with IC50 values of 0.177, 0.116 and 0.082 mg/mL, respectively. Besides, the ferrous ion chelating potency was better than others, with IC50 values of 0.63 ± 0.0044 mg/mL. The established method was suitable for large-scale separation of purified total SIs and provided a reference for purification of bioactive factors from complex substrates.
