Biological Activity

Description	D-Galactose (D-Galactopyranose, D-(+)-Galactose) is an aldohexose that occurs naturally in the D-form in lactose, cerebrosides, gangliosides, and mucoproteins and is converted enzymatically into D-glucose for metabolism or polysaccharides for storage. It accelerates senescence in invertebrates and mammals and has been used as a model for aging.
In vitro	D-Galactose (D-gal) can induce oxidative stress in non-cancer cells and result in cell damage by disturbing glucose metabolism. D-Gal treatment can transcriptionally up-regulate the genes relevant to necroptosis (Bmf, Bnip3) and autophagy (Atg5, TIGAR) but not the genes related to apoptosis (Caspase3, Bax, and p53). D-Gal does not activate Caspase-3, but prompts puncta-like GFP–LC3 distribution, an indicator for activated autophagy^[1].

Human hepatoma cell line HepG2 and human hepatocyte cell line LO2 are cultured in RPMI 1640 with 10% FBS. Cells are maintained at 37℃ with 5% CO2, and treated with D-gal or glucose in the concentrations and the time periods. Morphological assessments are conducted under microscope. Cell viability is evaluated by MTT assay.
