WormMine: ExpressionPattern Expr8890

• Pattern: The DAF-8::GFP translational fusion was expressed in developing embryos from the pre-comma stage through hatching. It was most highly expressed in L1 and gradually decreased into adulthood. Expression was strongly downregulated in dauer larvae. In larval stages, DAF-8::GFP was expressed throughout development in the ventral nerve cord, intestine, gonadal distal tip cells (DTCs) and subsets of head and tail neurons, most strongly in head neurons ASI and ADL. These neurons were identified by comparing GFP expression with DiI staining, which stains ciliated neurons in the head. In adults, DAF-8::GFP was also detected in the excretory cell.
• Primary Identifier: Expr8890

Definition	Name	Synonym	Primary Identifier
A chain of very large cuboidal cells forming a wide central lumen in which food arrives from the posterior pharynx, is digested, and from which waste products proceed to the rectum. Intestinal rings form in groups of two and four cells surrounding the common lumen; thus the epithelium is only one cell deep at any point, with neighboring cells firmly secured to their neighbors by apical adherens junctions. These cells have very large nuclei and many large vacuoles, yolk granules, and other inclusions; the latter increase in number and electron density as the animal ages.	intestine	gut	WBbt:0005772
