生化／生理作用
R115866 (Talarozole) is an orally active all-trans retinoic acid (RA) metabolism blocking agent (RAMBA; IC50 = 4 nM against RA metablism in yeast microsomes expressing human CYP26) with much reduced or little potency against CYP19 (aromatase), CYP17 (17,20-lyase), CYP2C11, CYP3A, and CYP2A1 (IC50 from 1.2 to >10 μM). Plasma and tissue RA upregulation via R115866 oral treatment exhibits in vivo efficacy in several retinoid-responsive rodent models, including vaginal keratinization suppression (ED50 = 1.0 mg/kg/day vs. 5.1 mg/kg/day with RA in rats), pinnal hyperplasia induction (ear epidermis thickness = 35.5 μm with 2.5 mg/kg/day R115866 vs. 16.5 μm in control mice), conversion of caudal para- to ortho-keratosis (90% with 1.25 mg/kg/day R115866 vs. 30.3% in control mice). Comparing to liarozole, R115866 is CYP26-selective and does not inhibit CYP-mediated biosynthesis of adrenal and gonadal steroid hormones.

All-trans-retinoic acid (atRA) is the active metabolite of vitamin A. The liver is the main storage organ of vitamin A, but activation of the retinoic acid receptors (RARs) in mouse liver and in human liver cell lines has also been

Cytochrome P450 CYP26 enzymes are responsible for all-trans-retinoic acid (atRA) clearance. Inhibition of CYP26 enzymes will increase endogenous atRA concentrations and is an attractive therapeutic target. However, the selectivity and potency of the existing atRA metabolism inhibitors toward CYP26A1 and

Despite the fundamental importance of patterning along the dorsal-ventral (DV) and anterior-posterior (AP) axes during embryogenesis, uncertainty exists in the orientation of these axes for the mesoderm. Here we examine the origin and formation of the zebrafish kidney, a ventrolateral

Interactions between multiple myeloma (MM) cells and the BM microenvironment play a critical role in bortezomib (BTZ) resistance. However, the mechanisms involved in these interactions are not completely understood. We previously showed that expression of CYP26 in BM stromal cells

Motor neurons are found throughout the developing chick hindbrain, while somatic motor (SM) neurons develop only in rhombomeres 5 to 8 (r5-8), and in r1. In r2-8 neuroepithelial explants from stage 7-10 embryos cultured in collagen gels, we found that
