Experimental Protocol

We had three experimental groups. Group A, VPA treatment; Group B, Dexamethasone treatment; and Group C, No treatment (vehicle saline control). Treatments were administered prior to the induction of left renal ischemia. Animals underwent 45 minutes of left renal ischemia, followed by reperfusion, and right nephrectomy as described above. Following reperfusion, animals were sacrificed at 3, 24 or 120 hours (n=8/group). In the 3 hour group, rats were maintained under anesthesia after surgery until sacrifice. In the 24 and 120 hour groups, the rats were recovered and returned to the cages for normal housing. Analgesic buprenorphine (0.05mg/kg) was administered every 12 h for three days post-operatively. After animal sacrifice, urine, blood, and kidney were collected for kidney functional biomarker assays, histology and / or molecular analyses. Urine was obtained via cystocentesis and blood was obtained via the left renal vein. Tissue and urine samples collected from normal (naïve) animals (n=5) were used for baseline measurements. A subset of 46 animals (n = 4-5 per group) were selected for microarray analysis.
