Single mesodermal cells guide outgrowth of ectodermal tubular structures in Drosophila

Article Abstract:

The discovery of a mesodermal cell that links the leading cells of Drosophila tracheal system main branches before they fuse is reported. The Drosophila tracheal system has branch outgrowth triggered by localized, transient activity of Branchless. The bridge-cell acts as an essential guide and must have Hunchback (Hb) activity to work. It gives cues acting with Bnl/dFGF signaling to mediate directed branch outgrowth that leads to position-specific branch fusion, ultimately.

Drosophila Fos mediates ERK and JNK signals via distinct phosphorylation sites

Article Abstract:

Drosophila Fos has been found to mediate ERK and JNK signals through distinct phosphorylation sites. Fos can mediate ERK signaling in wing vein formation and photoreceptor differentiation.

Distinct functions of the leucine-rich repeat transmembrane proteins Capricious and Tartan in the Drosophila tracheal morphogenesis

Article Abstract:

The role of leucine-rich repeat transmembrane proteins, Capricious and Tartan, in development of tracheal system during morphogenesis in Drosophila, is analyzed. These proteins help tracheal cells to interact with mesodermal cells.
