The ectodysplasin (EDA) pathway, which is active during the development of ectodermal organs, including teeth, hairs, feathers, and mammary glands, and which is crucial for fine-tuning the developmental network controlling the number, size, and density of these structures, was discovered by studying human patients affected by anhidrotic/hypohidrotic ectodermal dysplasia. It comprises three main gene...
Organisms modulate their growth according to nutrient availability. Although individual cells in a multicellular animal may respond directly to nutrient levels, growth of the entire organism needs to be coordinated. Here, we provide evidence that in Drosophila, coordination of organismal growth originates from the fat body, an insect organ that retains endocrine and storage functions of the vertebrate...
The RFX family of transcription factors is characterized by a unique DNA binding domain. Five genes have been isolated in mammals, one gene in Caenorhabditis elegans and in the yeasts Schizosaccharomyces pombe and Saccharomyces cerevisiae. Whereas the roles of the RFX genes are beginning to be understood in yeasts, no clear function has been reported in multicellular organisms, except for RFX5, the...
