AbstractCell death is often an active and highly choreographed process of cell suicide known as apoptosis. The molecular signals governing this process have been the subject of intense research in recent years. During apoptosis a profusion of pathways either promote cellular survival or lead to certain death. These pathways engage in constant crosstalk

Prokineticin-signaling pathway
The International Journal of Biochemistry & Cell Biology, 2008Prokineticin signaling comprises two secreted proteins (Prok-1 and Prok-2) and two cognate G-protein coupled receptors (PK-R1 and PK-R2) that are widely expressed in different tissues and of great versatility. Prokineticins were originally identified as the potent agents mediating gut motility in the digestive system, but were later shown to promote ...

Brassinosteroid Signaling Pathway
Science's STKE, 2006Plant growth is regulated by an intricate network of hormonal signaling pathways. These small-molecule hormones cause changes in gene expression that are associated with cell expansion and division and changes in development. Paradoxically, six of these hormones appear to have largely overlapping functions, yet the loss of response to any ...

The structural simplicity of the plant hormone ethylene contrasts with its dramatic effects in various developmental processes, as well as in the cellular processes that ethylene initiates in response to a diversity of environmental signals. A single well-conserved signaling cascade mediates this broad spectrum of responses.

Jasmonates in plants are cyclic fatty acid–derived regulators structurally similar to prostaglandins in metazoans. These chemicals mediate many of plants' transcriptional responses to wounding and pathogenesis by acting as potent regulators for the expression of numerous frontline immune response genes, including those for defensins and ...

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.
