Chemicals that interfere with the metabolism of retinol to atRA, therefore, are a human health concern. During development of a screen for disruptors of this signaling pathway, we investigated whether the mouse pluripotent P19 cell metabolizes retinol to atRA and thus can be used in a cell-based screen for disruptors of the pathway. We found that retinol induced the identical pattern of homeobox gene expression as atRA and its precursor, retinal. Retinol was 160-fold less potent than atRA as an inducer, however. In spite of its lower potency, increased Hoxa1 gene expression was detected 30 min after retinol exposure and increased 40-fold by 2 h. Rdh10 and Aldh1a2/Raldh2, which together convert retinol to atRA in the embryo, were the predominant alcohol and aldehyde dehydrogenases expressed in P19 cells. The cell expressed high mRNA levels of retinol binding proteins, Rbp1 and Rbp4, and the 13,14-dihydroretinol saturase, Retsat. It also expressed all Rar and Rxr isotypes, Crabp1&2, the three Cyp26 genes, and both β-carotene-cleaving genes, Bcmo1 and Bco2. The basal expression levels and retinol responsiveness of 25 pathway-related genes were quantitated by RT-qPCR. A test of the Aldh1a2 inhibitor, citral, showed that the disruption of the pathway was easily detected and quantitated showing that the P19 cell provides an in vitro model system for identifying and exploring the mechanism of action of chemicals that interfere with this critical cellular pathway."xsd:string |
