signal transduction

n.
The process by which a signal, such as a hormone or a change in the concentration of an ion, is converted into a biochemical response by means of the activation of a receptor on the surface or interior of a cell.

Among the signal transduction pathways in pituitary gonadotrophs, the PKC-MAPK pathway primarily activates c-Jun, Elk-1, and Egr-1, and the cAMP-PKA pathway primarily activates CREB and Egr-1, while the Ca2+-mediated signaling pathway primarily activates Nur77, c-Jun, and Egr-1 (Naor et al., 1997; Melamed et al., 2012; Thompson et al., 2013).
They are regulated by combinations of multiple signal transduction pathways, genes, and transcription factors.
In conjunction,the RAS-RAF-MEK-ERK signal transduction pathway is among the most fundamental intracellular signalling pathways found in the majority of cells and is responsible for regulating key cellular activities including cell growth, proliferation, survival, and apoptosis.
Editor's Note: Calcium plays a vital role in maintaining normal physiologic function, particularly signal transduction, and that severely low blood calcium levels have been associated with an increased risk of death.
The most promising versatile first-in-class molecular targets predominantly consist of receptor tyrosine kinases and their downstream signal transduction kinases, although a number of other cancer-related processes such as DNA repair, cancer immunosurveillance and apoptotic pathways are also targeted.
The association of exposures to low levels (levels which are not immunosuppressive in vivo or trigger immune cell death in vitro) of [Hg.sup.2+] with autoimmunity suggests that [Hg.sup.2+] could potentially interfere with signal transduction pathways in immature B cells in a manner so as to compromise central tolerance.
They use the case-based approach, is familiar to most practitioners, to cover DNA synthesis and repair, RNA transcription and translation, chromosomal dynamics and stability, cell surface receptors and signal transduction, nuclear hormone receptors, mechanisms of cell death, cancer metabolism, cancer stroma, immunological response to cancer, and hematopoietic stem cells.
