    摘要: The present invention provides a method for preferentially reducing the proliferation of cystic epithelial cells in the kidney or bile duct in a mammal in need thereof by administering a 20-HETE synthesizing enzyme inhibitor or a 20-HETE antagonist to the mammal in an amount sufficient to preferentially reduce the proliferation of cystic epithelial cells over normal epithelial cells such as tubule epithelial cells in the kidney or bile duct. The present invention also provides a method for preventing or treating autosomal dominant polycystic kidney disease (ADPKD), autosomal recessive polycystic kidney disease (ARPKD), ARPKD associated congenital hepatic fibrosis, ARPKD associated Caroli's disease, or cholangiocarcinoma in a mammal in need thereof by administering a 20-HETE synthesizing enzyme inhibitor or a 20-HETE antagonist to the mammal in an amount sufficient to prevent or treat the disease.

    摘要: A rat model of diabetic nephropathy is disclosed. In another embodiment of the invention, a method of evaluating a test compound's effect of diabetic nephropathy is disclosed. In one embodiment, this method comprises the steps of (a) exposing the test compound to the rat of claim 1, wherein the rat would develop progressive proteinuria and glomerulosclerosis leading to diabetic nephropathy in the absence of the test compound, and (b) comparing the rat's development of diabetic nephropathy with a control T2DN mimic rat that has not been exposed to the test compound.

    摘要: The present invention provides a fluorescent HPLC assay for detecting the presence and/or measuring the level of 20-hydroxyeicosatetraenoic acid (20-HETE) and other P-450 metabolites of arachidonic acid in a sample. P-450 metabolites of arachidonic acid are first extracted from the sample and then labeled with 2-(2,3-naphthalimino)ethyl trifluoromethanesulfonate. The labeling reaction is catalyzed by N,N-diisopropylethylamine. Next, the labeled P-450 metabolites are separated on a 4.5×250-mm, 5 &mgr;M particle size C18 reverse-phase HPLC column using a mobile phase of methanol:water:acetic acid (82:18:0.1, v/v/v) and an isocratic elution at a rate of about 1.3 ml per minute. Fluorescence intensities of the column eluent are monitored by a fluorescence detector. Quantitation of P-450 metabolites in a sample can be made by using an internal standard.
