Recently, it was demonstrated that nitric oxide (NO) and cGMP are involved in the auxin response during the adventitious rooting process in cucumber (Cucumis sativus; Pagnussat et al., 2002, 2003).

Scientists have achieved a quantitative in vivo measurement of the dynamic protein-protein interactions in the mitogen-activated protein kinase cascade signaling pathway, which is critical to growth ...

Mitogen-activated protein kinase (MAPK) networks are essential for the transmission of extracellular signals into appropriate intracellular responses. Prototypical MAPK activation implements a ...

Under severe environmental stresses such as high temperature, dryness and high salination, cells survive by responding appropriately through elaborate mechanisms, according to new cell biology ...

An overactive signaling pathway is a common cause in cases of pilocytic astrocytoma, the most frequent type of brain cancer in children. In all 96 cases studied, researchers found defects in genes ...
