WormMine: ExpressionPattern Expr14593

• Pattern: hlh-2, hlh-3, and hlh-4 are all expressed in ADL neurons but in a temporal specific manner. While hlh-2 is expressed in ADL throughout development from the embryo to the adult consistent with previous reports, we find that both hlh-3 and hlh-4 are transiently expressed in ADL. Expression of hlh-3 in ADL is observed in the late embryo before hatching, but not in L2 larvae or in adults. However, it remains possible that hlh-3 is very lowly expressed in ADL. In contrast, we observed that hlh-4 is expressed in ADL neurons in L1 larvae and in adults, but we did not observe hlh-4 expression in ADL in late-staged embryos before hatching. We observed that similar to hlh-4, hlh-10 is expressed in ADL neurons in larvae and adults, again opposite to the expression of hlh-3 observed in ADL. Thus, while hlh-2 is expressed in ADL throughout development, hlh-3 and hlh-4 may be transiently expressed in ADL.

	The first stage larva. At 25 Centigrade, it ranges 14-25.5 hours after fertilization, 0-11.5 hours after hatch.		L1 larva Ce	WBls:0000024
	The C. elegans life stage spanning 620-800min(hatch) after first cleavage at 20 Centigrade. Cell number remains at ~560 cells, with some new cells generated and some cells go through programmed cell death. A stage after elongation is over. The last stage of embryogenesis. Also called pre-hatched embryo, late embryo or morphogenetic embryo.		fully-elongated embryo Ce	WBls:0000021
