ecdysone/과민반응

The let-767 gene encodes a protein that is similar to mammalian steroid enzymes that are responsible for the reduction of 17-beta hydroxysteroid hormones. Caenorhabditis elegans is incapable of the de novo synthesis of cholesterol. Therefore, this free-living nematode must extract cholesterol from

At the end of the third larval instar of Drosophila, ecdysone triggers the tissue-specific activation of gene expression. In cytogenetic and molecular studies, the Broad-complex (BR-C) locus has been defined as a key element in the hierarchy of hormonal regulation of gene activity. Here we show that
