Seven major cell–cell signaling pathways—Wnt, TGF, Hedgehog (Hh), receptor tyrosine kinase (RTK), nuclear receptor, Jak/STAT, and Notch—control the vast majority of cell fate decisions during the development of bilaterian animals (Gerhart 1999). Each pathway is used repeatedly during the development of a given organism, activating different subsets of target genes in different developmental contexts. These seven pathways are strikingly diverse in both their complexity and the biochemical…

Mapping signaling pathway cross-talk in Drosophila cells
TLDR
This study, focusing on seven core pathways, revealed that many ligands and receptors are primary targets of signaling pathways, highlighting that transcriptional regulation of genes encoding pathway components is a major level of signaling cross-talk.
Signaling mechanisms controlling cell fate and embryonic patterning.
TLDR
Examples from Drosophila illustrate their abilities to act either at a short range or over a long distance, and in some instances to generate morphogen gradients that pattern fields of cells in a concentration-dependent manner, and show how feedback loops and transcriptional cascades are part of the logic of developmental regulation.
Control of microRNA biogenesis and transcription by cell signaling pathways.
Characterization of Schnurri : an integral component of the Dpp-signaling pathway in "Drosophila melanogaster"
TLDR
Schnurri is the first examples that link TGF-β signaling to tissue-unspecific repression rather than activation, and forms a signal-dependant DNA-protein complex on short silencer elements within the brinker regulatory region.
Mechanisms underlying differential responses to FGF signaling.
Wnt signaling through T-cell factor phosphorylation
TLDR
This review focuses on recent progress in the understanding of context-dependent post-translational regulation of TCF function by Wnt signaling.
The CSL proteins, versatile transcription factors and context dependent corepressors of the notch signaling pathway
TLDR
The aim of this review is to describe the different co-repressor proteins that interact directly with CSL proteins to form repression complexes thereby regulating the Notch signaling pathway in animal cells to give insights into the paralogous evolution of these co- repressors in higher eumetazoans and their subsequent effects at developmental processes.
Nodal points and complexity of Notch-Ras signal integration
TLDR
The transcriptional output of Notch–RTK cross-talk during Drosophila development is examined and in vivo data supporting a role for selected mutually regulated genes in signal integration is presented, suggesting Notch may function to specify the response to Ras activation.
Role of glycans and glycosyltransferases in the regulation of Notch signaling.
TLDR
Studying how sugar modification modulates Notch signaling provides a framework for better understanding the role of glycosylation in animal development and might offer new tools to manipulate NotCh signaling for therapeutic purposes.

Transcriptional control by the TGF‐β/Smad signaling system
TLDR
TGF‐β family members are multifunctional hormones, the nature of their effects depending on what has been called ‘the cellular context’ warrants mention at the outset.
Regulation of the dorsal morphogen by the Toll and torso signaling pathways: a receptor tyrosine kinase selectively masks transcriptional repression.
TLDR
The results suggest that RTK signaling pathways can control gene expression by antirepression, and that multiple pathways can fine-tune the activities of a single transcription factor.
Mae mediates MAP kinase phosphorylation of Ets transcription factors in Drosophila
TLDR
The study indicates that MAPK signalling specificity may depend on proteins that couple specific substrates to the kinase, and reports the cloning and characterization of a new component of this signal transduction pathway called Mae.
Axis induction by wnt signaling: Target promoter responsiveness regulates competence.
TLDR
It is argued that the competence of Wnts to induce a dorsal axis is lost in the nucleus, as a result of changes in the responsiveness of target promoters.
Regulatory control of signal transduction during morphogenesis in Drosophila.
TLDR
The negative regulatory control of signal transduction pathways could be a general mechanism regulating differentiation and morphogenesis.
An absolute requirement for Cubitus interruptus in Hedgehog signaling.
TLDR
This work addresses the question of whether the Hh pathway is distally branched or, in other words, whether the regulation of Ci activity is the sole output of Hh signaling and proposes that most cases of apparent Ci/Gli-independent Hh output can be attributed to the derepression of target gene expression in the absence of Ci/gli repressor function.
EGF receptor signaling induces pointed P1 transcription and inactivates Yan protein in the Drosophila embryonic ventral ectoderm.
TLDR
The simultaneous effects of the DER pathway on pntP1 induction and Yan inactivation may contribute to the definition of the border of the ventralmost cell fates.
Curbing the nuclear activities of β‐catenin
TLDR
Post‐translational modifications modulate the interactions between TCFs and β‐catenin or DNA, and certain transcription factors can sequester β‐Catenin from TCFs while others synergize with β‐ catenin–TCF complexes in a promoter‐specific manner, and contribute to the complexity and specificity of Wnt target gene regulation.
1998 Warkany lecture: signaling pathways in development.
TLDR
The study of model organisms, even of nonvertebrate groups, is expected to continue to contribute greatly to the understanding of mammalian development and to offer opportunities to analyze the effects of toxicants on development, as well as opportunities to devise incisive assays for toxicants.
