Abstract:

To observe the metabolic features of glioma cells by proton magnetic resonance spectroscopy (1H-MRS) at 14.7T high strength magnetic field. Methods  Glioma cell lines C6 and  U251 were cultivated. Water-soluble metabolites were extracted by adding perchloric acid. 1H-MRS at 14.7T magnetic field was acquired and special metabolic ratios were calculated, including lactate (Lac) / creatine (Cr), succinate (Suc) / Cr, N-acetylaspartate (NAA) / Cr, choline (Cho) / Cr, Cho / NAA, Glycine (Gly) / Cr, and myo-inositol (MI) / Cr. Results  C6 and U251 cell lines had almost the same water-soluble metabolites but different metabolic ratios. Conclusion  MRS can be used to analyze cells’ metabolic features and monitor physiological or pathological state at the cell level.
