From: Measuring the lactate-to-creatine ratio via 1H NMR spectroscopy can be used to noninvasively evaluate apoptosis in glioma cells after X-ray irradiation

Fig. 4

The Lac/Cr ratios were detected using 1H NMR spectroscopy and analyzed using MestreNova software. a and b – With increasing X-ray irradiation, the Lac/Cr ratios of C6 and U251 decreased significantly. c and d – The Pearson’s correlations between the p-PKC-ι level and Lac/Cr ratio were analyzed using SPSS 17.0. The p-PKC-ι level and the Lac/Cr ratio exhibited a positive linear correlation (rC6 = 0.980 and rU251 = 0.905)
