WormMine: ExpressionPattern Expr8978

• Pattern: Staining was evident in most somatic cells of the worm and was particularly prominent in the large gut cells. Staining was also observed in the nerve ring and in neurons.
• Primary Identifier: Expr8978
• Remark: Picture: Fig 1a, 1b. Transcriptional reporter gene constructs containing either 2.3 kb or 4.1 kb of daf-21 upstream sequence were generated. Analysis of b-galactosidase staining in these worms demonstrated that both promoters drive similar patterns of gene expression in all life cycle stages. However, in transgenic worms carrying the longer promoter, GFP fluorescence was also observed which was not apparent using the shorter promoter. For this reason, the longer promoter was used in all subsequent constructs.

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
