Extracellular signal regulated protein kinase

PKA and PKC are, however, not the only kinases to regulate TRPVl. The Ca /calmodulin-dependent kinase II (CaMKII) sensitizes TRPVl by phosphorylation [57, 58], as does phophatidylinositol 3-kinase (PI3K) via its downstream target AKT [59]. This latter finding links TRPVl to the ERK (extracellular signal-regulated protein kinase) pathway. The non-receptor tyrosine kinase Src likewise potentiates capsaicin-induced currents [60].

The best characterized family of MAPKs in the brain are the extracellular signal-regulated protein kinases (ERKs) that are activated by the neurotrophins and related growth factors (Fig. 23-4) [14,15]. The MAPK kinases responsible...

Treatment of hippocampal slices with kainate produces a time-dependent increase in NF-/< B levels in areas CA3 and CA1, but not dentate gyrus, compared with controls (Lubin et al., 2005). The kainate-mediated NF-kB complex that binds to DNA is composed of p65, p50, and c-Rel subunits. Pharmacological studies indicate that extracellular signal-regulated protein kinase (ERK) and Ptdlns-3K...

On the basis of the studies reported above, a possible mechanism may involve extracellular signal-regulated protein kinases (ERKs) and p38 kinase-mediated p53 activation and induction of apoptosis [148, 160] (Fig. 2). In the mouse JB6 epidermal cell line [161, 162], resveratrol induced apoptosis to inhibit tumor promoter-induced cell transformation through enhanced transactivation of p53 activity [148]. Resveratrol-induced activation of p53 and apoptosis was shown to be dependent on the activities of...
