Intracellular signaling cascades amplify a signal originating extracellularly and directs it to its intended intracellular target resulting in transcription, translation, protein modifications, enzyme activation, cellular metabolism, mitosis, and/or apoptosis. The most basic of signaling cascades involves the activation of second messengers and the release of kinases. These communications between cells triggers intracellular signaling cascades, termed signal transduction pathways, that regulate specific cellular functions. Each signal transduction occurs with a primary extracellular messenger that binds to a transmembrane or nuclear receptor, initiating intracellular signals.

Together, Raf, MEK, and the ERKs make up a three-tiered kinase signaling pathway called a mitogen-activated protein kinase (MAPK) cascade. (A mitogen is a signal that causes cells to undergo mitosis, or divide.) The intracellular signalling cascade in a cancer cell begins with the activation of a membrane receptor (with tyrosine kinase activity) when the latter binds with its ligand or through an external stimulus (e.g. change in osmosis, oxidative stress, lack of nutrients, etc.). To characterize the caspase-9 signaling cascade in intact cells, we employed chemically induced dimerization to activate caspase-9 specifically. Dimerization of caspase-9 led to rapid activation of effector caspases, including caspases-3, -6 and -7, as well as initiator caspases, including caspases-2, -8 and -10, in H9 and Jurkat cells.

Spermatozoa were incubated in sperm Tyrode's albumin lactate pyruvate (Sp-TALP) medium supplemented with (40 ng ml(-1)) or without relaxin, and subjected to evaluation of chlortetracycline Abstract. Introduction:Intracellular signaling cascades including mTOR (mammalian target of rapamycin), MEK (mitogen-activated protein kinase), BCL2 (B-cell lym Intracellular signaling pathways downstream from glutamatergic signaling and regulation by serotonin, which lead to communication between pre- and postsynaptic elements, leading to distinct neural patterns in the barrel cortex, are emerging (reviewed in Barnett et al., 2006a; Rebsam and Gaspar, 2006).

Lactate signaling cascade was recently linked to some cardiovascular disorders for its regulatory functions to myocardial structural remodeling. It was hypothesized that lactate signaling cascade was involved in the maintenance and recurrence of atrial fibrillation by regulating atrial structural remodeling.

The recognition process between Intracellular signaling cascades amplify a signal originating extracellularly and directs it to its intended intracellular target resulting in transcription, translation, Oct 9, 2007 Abstract. Intracellular signaling pathways that share common components often elicit distinct physiological responses. In most cases, the Oct 30, 2006 Here, we will introduce the most prevalent signaling pathway modules. Most receptors are transmembrane proteins that receive extracellular Despite this, we found that, besides this signaling cascade, the AC/PKA pathway is also required for ghrelin to increase porcine GH release because blockade of Our current understanding of the spatio–temporal organization of signaling processes and its control by cellular topology, diffusion and intracellular movement, Apr 3, 2015 Ligand binding and activation of cell surface and internal receptors triggers the activation and/or suppression of signaling cascades that regulate Nov 29, 2018 Abstract.

In Summary: Methods of Intracellular Signaling. Ligand binding to the receptor allows for signal transduction through the cell. The chain of events that conveys the signal through the cell is called a signaling pathway or cascade. Signaling pathways are often very complex because of the interplay between different proteins.
