Collection:

Collection ID:CO001698
Collection Summary:While under isoflurane anesthesia, tissues were rapidly dissected and snap frozen in liquid nitrogen and stored at -80°C until metabolite extraction. The following tissues were used in this study: kidney, liver, heart (left ventricle), skeletal muscle (quadriceps). Euthanasia was carried out by thoracotomy followed by cervical dislocation.

Treatment:

Treatment ID:TR001718
Treatment Summary:To induce CKD, we utilized an established adenine-diet model. Briefly, mice were assigned to a casein-base chow for 7-days, followed by induction of renal tubular injury by supplementing the diet with 0.2% adenine for 7-days, and subsequently maintained on a 0.15% adenine diet for 5 months and two weeks. CKD mice were then placed back on casein control diet for 2-weeks prior to euthanasia and terminal experiments, allowing for a washout period of adenine based chow. Control mice received casein diet for the duration of the study. Total duration of CKD encompassed 6-months.

Sample Preparation:

Sampleprep ID:SP001711
Sampleprep Summary:A modified form of FOLCH extraction protocol was used to extract metabolites from the tissues. Wet weights of all tissue samples were recorded prior to extraction. Tissue samples were immediately homogenized to prevent any possible enzymatic action using 1 mL of ice-cold methanol in a PowerLyzer 24 Homogenizer (QIAGEN Group, Hilden, Germany). The mixture was centrifuged using 13,200 rpm at 4oC for 30 minutes and the resulting supernatant was transferred to a new glass vial consisting 3 mL of ice cold chloroform:methanol (2:1, v/v) mixture. The homogenate was vortexed and left in an ice bath for 15 minutes to allow for phase separation. Next, 1 mL of 0.9% of saline was added, vortexed it for couple of minutes followed by a second incubation in an ice bath for 30-45 min for complete phase separation. The upper aqueous layer was transferred to a new falcon tube. To the remaining organic phase sample, 1 mL of 0.9% of saline was added again followed by vigorous mixing and letting it stand in ice bath (15 minutes) for a second phase separation. This second aqueous phase was combined with the first. The resulting aqueous and organic layers were dried separately. The aqueous layer was dried overnight with a Labconco freezer dryer (Labconco Corporation, MO, USA) and the organic layer was dried via inert nitrogen gas. These two dried powders (aqueous and organic phases) were stored at -80oC until performing NMR experiments.
