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. |

Collection Summary: | All animal studies were performed under the protocol approved by the Institutional Animal Care and Use Committee (IACUC) of Boston Children’s Hospital (BCH). Mice (CD-1 males) kept in circadian cabinet housing with 12-hour light cycle (7 a.m. on/ 7 p.m. off) aged 8 weeks (N =16 at each time—9 a.m. and 9 p.m.), were decapitated and brain tissue was immediately dissected and frozen on dry ice. ChP were extracted by brief sonication in either 200µl 80% LC/MS-grade methanol extraction solvent or 200µl of ”FB” extraction solvent (80% LC/MS-grade methanol, 20% 25 mM Ammonium Acetate and 2.5 mM Na-Ascorbate prepared in LC/MS water and supplemented with isotopically labeled internal standards (17 amino acids and isotopically labelled reduced glutathione, Cambridge Isotope Laboratories, MSK-A2-1.2 and CNLM-6245-10). After centrifugation for 10 min at maximum speed on a benchtop centrifuge (Eppendorf) the cleared supernatant was dried using a nitrogen dryer and reconstituted in 20 µl water (supplemented with QReSS, Cambridge Isotope Laboratories, MSK-QRESS-KIT) by brief vortexing. Extracted metabolites were spun again and cleared supernatant was transferred to LC-MS micro vials. A small amount of each sample was pooled and serially diluted 3- and 10-fold to be used as quality controls throughout the run of each batch. |
