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].

Protocol (from reference)

Cell Assay:

[1]

  • Cell lines

    Mouse neuroblastoma cell line Neuro2a (N2a), human neuroblastoma cell line SH-SY5Y, human prostate cancer cell line PC-3 and mouse fibroblast cell line NIH3T3; Human hepatoma cell line HepG2 and human hepatocyte cell line LO2

  • Concentrations

    0-60 g/L

  • Incubation Time

    24 h

  • Method

    Mouse neuroblastoma cell line Neuro2a (N2a), human neuroblastoma cell line SH-SY5Y, human prostate cancer cell line PC-3 and mouse fibroblast cell line NIH3T3 are cultured in DMEM supplemented with 10% FBS, 100 U/ml penicillin, and 100 mg/ml streptomycin. 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.
