Compartments are units of cell lineage that subdivide territories with different developmental potential. In Drosophila, the wing and haltere discs are subdivided into anterior and posterior (A/P) compartments, which require the activity of Hedgehog, and into dorsal and ventral (D/V) compartments, needing Notch signaling. There is enrichment in actomyosin(More)
Hox gene activity leads to morphological diversity of organs or structures in different species. One special case of Hox function is the elimination of a particular structure. The Abdominal-B Hox gene of Drosophila melanogaster provides an example of such activity, as this gene suppresses the formation of the seventh abdominal segment in the adult. This(More)
The inhibitory effect of fat in the upper small intestine was studied in dogs prepared with a Heidenhain pouch, gastric fistula, and jejunal fistula. Gastric secretion was stimulated by a constant intravenous infusion of pentagastrin, and emulsified olive oil was introduced into the jejunum. The small intestine of the dog was denervated by complete(More)
