The C. elegans insulin/IGF-1 signaling (IIS) pathway connects nutrient levels to metabolism,
growth, development, longevity, and behavior. This fundamental pathway is regulated by …

This exploration of American women's post-World War II higher education begins with three
stories. These narratives reflect issues women faced when, as educators, they tried to plan …

Mouse Cdx and Hox genes presumably evolved from genes on a common ancestor cluster
involved in anteroposterior patterning. Drosophila caudal (cad) is involved in specifying the …

Organogenesis is dependent on the formation of distinct cell types within the embryo.
Important to this process are the hox genes, which are believed to confer positional identities …

The gut offers a complex but rich organ system to study visceral pattern formation. The gut is
an early evolutionary advance. Data supports that the molecular controls of gut pattern …

In C. elegans, a bilateral pair of neuroblasts, QL and QR, give rise to cells that migrate in
opposite directions along the anteroposterior (A/P) body axis. QL and its descendants …

Spatially and temporally restricted expression of the Hox genes along the main and
appendicular axes is essential for correct patterning of vertebrate embryos. In this overview …

Septins have been shown to play important roles in cytokinesis in diverse organisms
ranging from yeast to mammals. In this study, we show that both the unc-59 and unc-61 loci …

Wnt glycoproteins are signaling molecules that control a wide range of developmental
processes in organisms ranging from the simple metazoan Hydra to vertebrates. Wnt …

The skin of the nematode Caenorhabditis elegans is composed of a simple epidermal
epithelium and overlying cuticle. The skin encloses the animal and plays central roles in …
