چکیده

The conservation of signaling cascades between humans and Drosophila, over more than 500 million years of evolutionary time, means that the genetic tractability of the fly can be used to its full advantage to understand the functional requirements for JAK-STAT pathway signaling across species. Here we review the background to how the pathway was first identified and the first characterization of JAK-STAT pathway phenotypes in the Drosophila system, highlighting the molecular, functional, and disease-related conservation of the pathway.

JAK-STAT pathway and JAK inhibitors: a primer for dermatologists

Background: All cellular events depend upon the DNA synthesis and gene expression involving complex interplay between ligands such as interleukins and interferons, with various cell membrane receptors. These ligand-receptors interactions transmit signals within the cell via numerous signal transduction pathways to affect gene expression. Janus kinase/signal transducer and activator of transcrip...

Drosophila unpaired encodes a secreted protein that activates the JAK signaling pathway.

In vertebrates, many cytokines and growth factors have been identified as activators of the JAK/STAT signaling pathway. In Drosophila, JAK and STAT molecules have been isolated, but no ligands or receptors capable of activating the pathway have been described. We have characterized the unpaired (upd) gene, which displays the same distinctive embryonic mutant defects as mutations in the Drosophi...

Polarity determination in the Drosophila eye: a novel role for unpaired and JAK/STAT signaling.

The JAK/STAT signaling pathway is required for many processes including cytokine signaling, hematopoiesis, gliagenesis, and Drosophila segmentation. In this report we present evidence demonstrating that the JAK/STAT pathway is also central to the establishment of planar polarity during Drosophila eye development. We show that a localized source of the pathway ligand, Unpaired, is present at the...

Regulation of proliferation, cell competition, and cellular growth by the Drosophila JAK-STAT pathway

The JAK-STAT pathway is a key regulator of tissue size in Drosophila melanogaster. Here we provide an overview of its roles in processes that regulate the size of Drosophila imaginal discs, epithelia of diploid cells that proliferate and acquire specific fates in the larvae and that become functional in the adult. Drosophila has a single JAK and a single STAT gene, which has facilitated genetic...

Modulation of human JAK-STAT pathway signaling by functionally conserved regulators

Both the core JAK-STAT pathway components and their in vivo roles have been widely conserved between vertebrates and invertebrate models such as Drosophila melanogaster. Misregulation of JAK-STAT pathway activity has also been identified as a key factor in the development of multiple human malignancies. Recently, whole genome RNA interference (RNAi) screens in cultured Drosophila cells have ide...
