Identification of a Spatio-Temporal Enhancer Element for the Alzheimer’s Amyloid Precursor Protein-Like-1 Gene in the Nematode Caenorhabditis elegans

抄録

During the larva-to-adult transition of the nematode Caenorhabditis elegans, expression of the Alzheimer’s amyloid precursor protein-like gene, apl-1, is temporally regulated in seam cells. This regulation requires several transcription factors, including nuclear receptor NHR-25. Here we describe a critical cis-regulatory element of apl-1 transcription. The element is conserved among Caenorhabditis sister species and is similar to nuclear receptor binding consensus.
