Other neurological abnormal ities were also recorded, such as alterations in balance, sensorial perception and reflex responses. Estradiol administration A total of 46 male rats were randomly distributed into the following experimental groups, sham vehicle, ischemia vehicle, sham estradiol, and ischemia estradiol. Groups SE and IE groups sellectchem received three doses of 0. 04 mg kg B estradiol in a total volume of 500 uL, delivered by intra peritoneal in jection 6, 24, and 48 h after pMCAO induction. Groups IV and SV received 500 uL of the vehicle alone. All animals were sacrificed 6 h after the last treatment. Western blotting Animals were sacrificed by exposure to CO2, decapitated and their brains were removed quickly. The right cerebral cortex and right hippocampus were dissected out and frozen at ?80 C for subse quent analysis.

Tissue samples were homogenized with a Teflon glass homogenizer in ice cold lysis buffer containing, 20 mM Hepes, Inhibitors,Modulators,Libraries 100 mM Inhibitors,Modulators,Libraries NaCl, 100 mM NaF, 5 mM EDTA, 1% Triton X 100, 1 mM Na3VO4, and a pro tease inhibitor cocktail. Samples were kept on ice for 30 min and the in soluble material was then removed by centrifugation at 12,000 x g for 15 min. The pellet was discarded and the supernatants were analyzed in western blots. The protein concentration Inhibitors,Modulators,Libraries of each sample was determined using the DC Protein Assay kit according to the manufacturers instructions. The proteins were resolved by SDS PAGE using a Mini Protean system and depending on the epitope to be analyzed, 30 50 ug of total protein was loaded into each lane in loading buffer containing, 0.

062 M Tris, 10% glycerol, 5% B mercaptoethanol, 7. 5 mM EDTA, 2% SDS, and 0. 002% bromophenol blue. Samples were heated at 100 C for 3 min before loading. After electrophoresis the Inhibitors,Modulators,Libraries proteins were electrotransferred onto nitrocellulose membranes for 1. 5 h at 100 mV using an electrophoretic transfer system. Subsequently, the membranes were blocked for 1 h with 5% non fat powdered milk Inhibitors,Modulators,Libraries in phosphate buffered saline con taining 0. 1% Tween 20 and then they were incu bated overnight at 4 C with the appropriate primary antibody, Akt, phospho AktSer473 Signaling no. 9251. The membranes were washed with PBS T and incubated for 1 h at room temperature with the corresponding secondary antibodies, peroxidase conjugated goat anti mouse IgG or goat selleck chemicals Ganetespib anti rabbit IgG HRP. Specific antibody binding was revealed using the Western Lightning ECL chemiluminiscence system, according to the manufacturers recommendations. Autoradiography was performed on AGFA RP2 plus films, using different exposure times depending on the primary antibody used. The films were analyzed using Quantity One software, version 4. 6.
