The NRMD is a database for nuclear receptor mutation information. It includes mutation information from SWISS-PROT/TrEMBL, several web-based mutation data resources, and data extracted from the literature in a fully automatic manner. Because it is also possible to add mutations manually, a hundred mutations were added for completeness. At present, the NRMD contains information about 893 mutatio...

Androgen receptor (AR) belongs to the superfamily of nuclear hormone receptors that employ complex molecular mechanisms to guide the development and physiological functions of their target tissues. Our recent work has led to the identification of four novel proteins that recognize AR zinc-finger region (ZFR) both in vivo and in vitro. One is a small nuclear RING-finger protein that possesses se...

Cytochrome P450s of the 4A subfamily generally catalyze the omega-hydroxylation of fatty acids. The induction of P450 4A enzymes by peroxisome proliferators or fatty acids is mediated by peroxisome proliferator-activated receptors (PPARs), which are members of the nuclear receptor family that regulates the expression of genes that control fatty acid synthesis, storage, and catabolism. PPARs bin...

Understanding nuclear receptor signaling in vivo would be facilitated by an efficient methodology to determine where a nuclear receptor is active. Herein, we present a feedback-inducible expression system in transgenic mice to detect activated nuclear receptor effector proteins by using an inducible reporter gene. With this approach, reporter gene induction is not limited to a particular tissue...

Based on plasma endotoxin/toll-like receptor-4/nuclear factor-kappa B signal pathway to investigate the protective effect of soothing liver mixture mice with injury induced by antituberculosis drugs. A total 72 Sprague Dawley male rats were randomly divided into blank control group, model silymarin group and (low, medium high dosage), 12 in each group. 16 h after last administration, pathologic...

Despite the apparent similarity of the dexamethasone-receptor concentration in the rat liver and Novikoff hepatoma cytoplasms, the in vitro translocation of the dexamethasone-receptor complex into liver or hepatoma nuclei was three times greater from liver as compared to hepatoma cytosol; both cytosols showed an apparent saturation of nuclear receptor sites. Although the competitive interaction...

Searching for a link between inflammation and colon cancer, we have found that the inflammatory mediator leukotriene D(4) (LTD(4)), via its receptor CysLT(1), induces cyclooxygenase-2 expression, survival, and proliferation in intestinal epithelial cells. In conjunction with our previous observation that CysLT(1) receptor expression is increased in colorectal adenocarcinomas, we here found an i...
