Intermine data mining platform for C. elegans and related nematodes

Expression Pattern :

Pattern  In adults nuclear-localised expression is observed in the hypodermal seam cells running from the head to the tail and in additional cells of the tail that could be the phasmids. There is some expression in other sites which may be artefactual. Weak and non-localised expression is also occasionally seen in late embryos and young larvae. Young larvae may exhibit strong non-localised staining of the pharynx which may persist to later stages. Expression has also been seen in the posterior intestinal nuclei or non-localised throughout the intestine. Such expression has been attributed to use of incomplete promoters but the upstream region in pUL#PB27 is 2.7kb, which is quite large and includes all but 1kb of the intergenic region. Primary Identifier  Expr107
Remark  Another strain generated with this plasmid, UL191, shows similar expression to UL256, though the component involving the seam cell expression is weaker and expression of the intestinal nuclei is stronger. Legacy Data: "Bauer PK" "Hope IA"Date 1998-01.

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
