ARG1 activity in tumours and plasma. A–C Graphical representation of arginine (A) and ornithine (B) levels in tumour in µmol/mg of tissue, as measured by mass spectrometry. (C) The ratio of arginine to ornithine. Bars represent the mean ± SEM, and each data point represents a single tumour (67NR N = 10, 66cl4 N = 11). Statistical significance was determined using the Mann–Whitney test. *p < 0.05, **p < 0.005, ***p < 0.0005. D–F show the levels of arginine (D) and ornithine (E) in µM in plasma, while (F) shows the ratio of arginine to ornithine in plasma. Bars represent mean ± SEM and each data point represents a single animal (control N = 12, 67NR N = 12, 66cl4 N = 12). Statistical significance was determined using the Mann–Whitney test. *p < 0.05, **p < 0.005, ***p < 0.0005
