Metabolome in a group of AA and EA matched pairs of prostate cancer (PCa) and benign adjacent tissues


ABSTRACT: 10 µL of suspended samples was injected and analyzed using a 6495 triple quadrupole mass spectrometer (Agilent Technologies, Santa Clara, CA) coupled to a HPLC system (Agilent Technologies, Santa Clara, CA) via Multiple reaction monitoring (MRM) of a total of 240 endogenous water soluble metabolites for steady-state analyses of samples. Those 240 compounds monitored were chosen due to their involvement in central pathways important in a number of malignancies. Source parameters were as follows: Gas temperature was 250 °C; Gas flow was 14 l/min; Nebulizer was 20psi; Sheath gas temperature was 350 °C; Sheath gas flow was 12 l/min; Capillary was 3000 V positive and 3000 V negative; Nozzle voltage was 1500 V positive and 1500 V negative. Approximately 8–11 data points were acquired per detected metabolite. Samples were delivered to the MS via normal phase chromatography using either a 4.6 mm i.d ×10 cm Amide XBridge HILIC column (Waters) or a Luna 3µ NH2 100A (Phenomenex) at 300 µL/min
