WormMine: ExpressionPattern Expr3693

• Pattern: Fluorescence was observed in epithelial cells that synthesize cuticle. Expressed in the hypodermis, including the major body syncytium, hyp7, and hypodermal cells in the head and tail. Also expressed in the lateral seam cells. Fluorescence in seam cells was observed, predominantly, before larval-to-larval molts, when the cells divide. A pulse of fluorescence was observed in the hypodermis prior to molting. Hypodermal expression of GFP from the mlt-11 promoter was detected from 51 +/- 2% to 72 +/-3% of the duration of each stage, suggesting that the MLT-11 anti-protease, synthesized midway through each larval stage. Expression of mlt-11::gfp-pest in the seam cells often preceded and lasted longer than expression in hyp7. Expression of the gfp fusion genes was never detected in the hypodermis of gravid adults that no longer molt.
