| Study Title | Levels of central carbon metabolites in choroid plexus as part of natural diurnal variation |
| Study Summary | This study employs targeted LC-MS analysis of choroid plexus (ChP) tissue to assess relative changes in the levels of intermediates from the central carbon metabolism, with additional attention to mitochondrial energy precursors (ATP/ADP, NAD(P) and NAD(P)H) at two time points in the diurnal cycle. For this purpose, mice were kept in a circadian cabinet housing with 12-hour light cycle (7 a.m. on/ 7 p.m. off) and tissues were collected consistently at an a.m and a p.m time point (9 a.m. and 9 p.m). Two different ChP tissues were collected for analysis (LV - left ventricle and 4V - 4th ventricle). Also two separate extractions were performed: 80% MetOH based ("MetOH" study factor) and FB (MetOH with Na-ascorbate and Na-acetate additives, "FB" study factor). The two extractions are optimal for central carbon metabolites or NAD(P)/H respectively. |

| MS Comments: | MS data acquisition was performed using a QExactive benchtop orbitrap mass spectrometer equipped with an Ion Max source and a HESI II probe (Thermo Fisher Scientific, San Jose, CA) and was performed in positive and negative ionization mode in a range of m/z = 70–1000, with the resolution set at 70,000, the AGC target at 1x106, and the maximum injection time (Max IT) at 20 msec. A narrower scan in positive mode at m/z = 600-800 was used for more specific detection of thyroxine hormones, the resolution was set at 70,000, the AGC target was 5x105, and the max IT was 100 msec. For polar metabolites HESI conditions were: Sheath gas frow rate: 35; Aug gas flow rate: 8; Sweet gas flow rate: 1; Spray voltage: 3.5kV (pos), 2.8kV (neg); Capillary temperature: 320ºC; S-lens RF: 50; Aux gas heater temperature: 350 ºC. |
