Collection:
Collection ID: | CO000345 |
Collection Summary: | At sacrifice, the genital urinary tract of male rats, comprising the bladder, urethra, seminal vesicles, and the prostate is excised, and microdissected under a dissecting microscope. The lateral prostate was removed, snapfrozen in liquid nitrogen, and stored at –80 °C. |

Sample Type: | Tissue |
Treatment:
Treatment ID: | TR000365 |
Treatment Summary: | Three dietary Zn modulated groups: Zn deficient, Zn replenished,and control Zn sufficient Male weanling rats were fed a Zn deficient diet ad libitum (n = 16) or pairfed a control Zn sufficient diet (n = 8). After 6 weeks Zn deficient rats evidenced increased cell proliferation in the esophagus. Eight Zn deficient rats were switched immediately to the Zn sufficient diet to form the Zn replenished group. At 72 hours after replenishment, all animals (Zn deficient, Zn replenished, and Zn sufficient;n = 8/group) were killed. Note: Zn sufficient is the control group for each tissue (plasma, esophagus, or prostate) |

Sample Preparation:
Sampleprep ID: | SP000359 |
Sampleprep Summary: | 1. Weigh 50 mg tissue sample in to a 25 ml conical polypropylene centrifuge tube. 2. Add 2.5mL extraction solvent to the tissue sample and homogenize for 45 seconds ensuring that sample resembles a powder. In between samples, clean the homogenizer in solutions of methanol, acetone, water, and the extraction solvent. 3. Centrifuge the samples at 2500 rpm. for 5 minutes. Aliquot 2 X 500µl supernatant, one for analysis and one for a backup sample. Store backup aliquot in the -20°C freezer. 4. Evaporate one 500µl aliquot of the sample in the Labconco Centrivap cold trap concentrator to complete dryness 5. The dried aliquot is then re-suspended with 500l 50% acetonitrile (degassed as given) 6. Centrifuge for 2 min at 14000 rcf using the centrifuge Eppendorf 5415. 7. Remove supernatant to a new Eppendorff tube. 8. Evaporate the supernatant to dryness in the the Labconco Centrivap cold trap concentrator. 9. Submit to derivatization. |
