Novel biological function of sialic acid (N-acetylneuraminic acid) as a hydrogen peroxide scavenger.

abstract：:Exposing a macrophage-like murine cell line to copper-oxidised low-density lipoprotein led to DNA fragmentation which was inhibited by the putative Ca2+/Mg2+ endonuclease inhibitor, zinc sulphate. DNA fragmentation preceded loss of membrane impermeability. These results suggest that apoptosis may be a mechanism of mac...

abstract：:F-box/LRR-repeat protein 2 (FBXL2), a component of Skp-Cullin-F box (SCF) ubiquitin E3 ligase, has been shown to inhibit tumorigenesis by targeting and ubiquitinating several oncoproteins. However, its role in gastric cancer remains poorly understood. Here, by tandem mass spectrometry, we show that FBXL2 interacts wit...
