1. The CYP4 family consists of 11 subfamilies (CYP4A-CYP4M), which encode constitutive and inducible isozymes expressed in both mammals and insects. 2. The CYP4A subfamily encodes several cytochrome P450 enzymes that are capable of hydroxylating the terminal omega-carbon and, to a lesser extent, the (omega-1) position of saturated and unsaturated fatty(More)
BTS 67582 (1,1-dimethyl-2-(2-morpholinophenyl) guanidine fumarate) is an insulin-releasing agent currently in phase II clinical trials. Its effect on advanced glycation end product (AGE) formation was measured in the BSA/D-glucose and L-lysine/glucose-6-phosphate assay systems and Amadori product formation was measured in the BSA/D-glucose assay system,(More)
Rats at day 15.5 of gestation were dosed intraperitoneally with 300 mg.kg-1 of clofibrate for three consecutive days at 24-hr intervals and were culled 24 hr after the final injection. This regime produced maximal induction of the cytochrome P4504A (CYP4A) mRNAs in the maternal liver and kidney and in 18.5-day fetal tissues. The maternal hepatic and renal(More)
Lactating mothers of 7.5-day neonatal rats were injected intraperitoneally with 500 mg kg-1 clofibrate for 3 consecutive days at 24-hour intervals; 24 hours after the final injection, the maternal cytochrome P450 4A (CYP4A) mRNA levels had risen 14- and 2.5-fold above the constitutive levels of expression seen in the liver and kidney, respectively.(More)
A simple, rapid method for determining depolarization-induced45Ca influx into synaptosomes is described. Synaptosomes which had been depolarized in the presence of45Ca were applied to a small column of Chelex-100 resin to separate free Ca2+ from that taken up by the tissue. Approximately 70% of the synaptosomal protein applied to the column was recovered in(More)
