WormMine: ExpressionPattern Expr1508

• Pattern: In L1, after induction by 0.1 mM CdCl2, the reporter enzyme was markedly induced in the 20 cells constitute the intestine. While in adults, the Cadmium induced only a low level of beta-gal activity in the intestinal cells. Expression of lacZ in pharyngeal cells was not significantly affected by Cadmium or development stage. In uninduced animals, mtl-1::lacZ was active in just three cells that are located in the posterior bulb of pharynx.
• Primary Identifier: Expr1508
• Remark: Express condition: induced by Calcium.

2 Anatomy Terms

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
the feeding organ, a neuro-muscular pump in the head of the animal, used to ingest food, bacteria suspended in liquid, filter them out, grind them up and transport posteriorly into the instestine.	pharynx	esophagus	WBbt:0003681
