WormMine: ExpressionPattern Expr11176

• Pattern: Expression of egl-20 is high throughout the entire life span of the worm and increases during aging. As in development, egl-20 expression was observed only in the posterior of the animal. The egl-20/Wnt is expressed in the anal depressor muscle and in the postembryonic rectal epithelial cells (B, F, K, and U) during aging. These cells also express egl- 20/Wnt during larval development (Gleason et al. 2006). However, the authors did not observe any expression in hypodermal or muscle cells, as previously reported.

a single, H-shaped cell which lies just above the anus and connects the roof of the anal canal to the dorsal bodywall; its contractions act to increase the size of the anal opening by lifting the roof of the rectum and hence facilitate expulsion of intestinal contents.	anal depressor muscle	dilator muscle	WBbt:0004292
