The Hedgehog (Hh) signaling pathway is essential for development and tissue homeostasis in metazoans. Probably as a result of its potent influence on cell-fate outcomes, the Hh pathway when corrupted results in malformations and diseases such as cancer. Many of the pathway components that contribute to Hh-mediated signal transduction are presented.

Toll-like receptors (TLRs) have been established to play an essential role in the activation of innate immunity by recognizing specific patterns of microbial components. TLR signaling pathways arise from intracytoplasmic TIR domains, which are conserved among all TLRs.

Cytokinins are key regulators of a large number of processes in plant development, which is highly plastic and adaptive, and remarkably resilient and self-perpetuating. Cytokinin signaling involves a multistep two-component system, also called a phosphorelay signaling system.

Gibberellin signalling pathway
Current Opinion in Plant Biology, 2003Recent molecular biological and genetical studies have identified several positive and negative regulators of gibberellin (GA) signalling pathways in higher plants. The DELLA protein functions as a negative regulator of GA signalling; its degradation through the ubiquitin/proteasome pathway is a key event in the regulation of GA-stimulated processes.

Osteoclast signalling pathways
Biochemical and Biophysical Research Communications, 2005The osteoclast is a monocyte-derived cell with complex regulatory control due to its role, balancing calcium homeostasis with skeletal modelling and repair. Normal differentiation requires tyrosine kinase- and tumor necrosis-family receptors, normally fms and RANK.

Notch is a receptor that mediates intercellular signaling through a pathway conserved across the metazoa. It is involved in cell fate assignation and pattern formation during development. The receptor acts as a membrane-tethered transcription factor and is activated by members of the Delta, Serrate, Lag-2 family of Notch ligands, which trigger two ...

Angiogenic Signalling Pathways
2008Hypoxia is widely recognised as a key driving force for tumor angiogenesis by its induction of vascular endothelial growth factor (VEGF) and other direct-acting angiogenic factors. We describe the effect of hypoxia on gene expression and downstream angiogenic signalling; however, the angiogenic process is complex, and many other signalling pathways ...

Signal Transduction: Just another signalling pathway
Current Biology, 1994The recently identified JAK-STAT signal transduction pathway plays a major role in signalling the arrival of cytokines at the cell surface and can, in part, account for the pleiotropic and redundant effects of cytokines.

Transforming growth factor-beta (TGFβ) is a key regulator of cell fate during embryogenesis and has also emerged as a potent driver of the epithelial-mesenchymal transition during tumor progression. TGFβ signals are transduced by transmembrane type I and type II serine/threonine kinase receptors (TβRI and TβRII, respectively). The activated TβR complex

The Ethylene Signaling Pathway
Science, 2004Plants use a structurally very simple gas molecule, the hydrocarbon ethylene, to modulate various developmental programs and coordinate responses to a multitude of external stress factors. How this simple molecule generates such a diverse array of effects has been the subject of intense research for the past two decades.
