Treatment ID:TR000855
Treatment Summary:Female db/db mice on a C57BL/6 background and age- and sex-matched wildtype (WT) C57BL/6J mice were purchased from The Jackson Labs at age 6 weeks, allowed to acclimatize within the mouse vivarium at the Harvard T.H. Chan School of Public Health for 4 weeks, and studied at 10 weeks of age. db/db and WT mice were exposed for 3 hours to room air or to O3 (2 ppm) in stainless steel and plexiglass exposure chambers {Shore, 2003 #480}. During exposure, mice were placed within individual wire mesh cages and food and water were withdrawn. Mice were returned to their home cages immediately after exposure at which time food and water were restored. Mice were euthanized with an overdose of sodium pentobarbital 24 hours after cessation of exposure. For mice in the metabolomics study, after euthanasia, blood was obtained by cardiac puncture for the preparation of serum. The chest wall was then opened and a small incision was made in the left ventricle. 10 ml of ice cold PBS was gradually injected into the right ventricle in order to flush blood from the lungs. The lungs were then flash frozen in liquid nitrogen and stored at -80oC until shipped on dry ice to Metabolon Inc. (Durham, NC). Upon receipt, the lungs were again frozen at -80oC until analysis.
