It is suggested, therefore, that the intrinsic mechanism of eotaxin-induced eosinophil rolling and migration involves activation of the p42/p44 MAPK, possibly through regulation of the cytoskeletal rearrangements necessary for chemotaxis..

Taken together, these findings suggest that NGF and LPA exert cross-talk regulation both at the level of p42/p44 MAPK signaling and in the nuclear translocation of LPA(1) and Trk A receptors.. /// "Fourth, the over-expression of C-terminal GRK2 peptide (which sequesters G-protein betagamma subunits) or beta-arrestin I clathrin binding domain (amino acids: 319-418) or pre-treatment of cells with pertussis toxin reduced the LPA- and NGF-dependent stimulation of p42/p44 MAPK. " /// "First, the treatment of PC12 cells, which express LPA(1) receptors, with a sub-maximal concentration of LPA and NGF induced synergistic activation of p42/p44 MAPK. " /// These findings support a model in which the Trk A receptor uses a G-protein-mediated mechanism to regulate the p42/p44 MAPK pathway. /// We report here that the nerve growth factor (NGF) and lysophosphatidate (LPA) receptor signaling systems interact to regulate the p42/p44 MAPK pathway in PC12 cells. /// "Second, the transfection of PC12 cells with LPA(1) receptor anti-sense construct, which reduced the expression of LPA(1), abrogated both LPA- and NGF-stimulated activation of p42/p44 MAPK. " /// "Third, the over-expression of recombinant LPA(1) receptor potentiated LPA- and NGF-dependent activation of p42/p44 MAPK. "

We previously reported that nuclear translocation is essential for p42/p44 MAPKs (ERKs) mitogenic signaling. /// "Hence, the nucleus is a critical site for mitogenic signal termination by: (1) nuclear sequestration of p42/p44 MAPKs away from MEK, their cytoplasmic activator. " /// "In addition, p42/p44 MAPKs permanently shuttle between the cytoplasm and the nucleus in quiescent as well as in serum stimulated cells. " /// "Here we show that, during long-term stimulation, p42/p44 MAPKs become inactive while they accumulate in the nucleus. " /// "The phosphatases responsible for p42/p44 MAPKs nuclear inactivation are neo-synthesized, show tyrosine or dual specificity, and interact with p42/p44 MAPKs via a specific docking site. " /// "This inactivation was monitored by phospho-specific immunostaining and dephosphorylation of a nuclear p42/p44 MAPKs substrate, HIF-1 alpha. "

Growth factors promote nuclear translocation and persistent activation of p42/p44 MAP kinases during the entire G0/G1 period. /// "Here, we demonstrate that induction of cyclin D1, and therefore cdk4/6 activity associated with, is positively controlled by the p42/p44 MAP kinase cascade whereas the parallel cytokines/stress-activated p38MAP kinase cascade is antagonistic. " /// Cell cycle re-entry requires the growth factor-stimulation of at least two distinct classes of protein kinases: (i) the p42/p44 MAP kinases activated by the Ras > Raf > MKK cascade and (ii) the G1 cyclin-dependent protein kinases (CDKs).

Preliminary data on hyperoxic signaling indicate that NF-kappa B translocation (and presumptive activation) is not a result of the p42/p44 MAPK pathway, but a likely downstream consequence of activation of the JNK pathway.

BK also stimulated translocation of p42/p44 MAPK into nucleus and led to expression of c-fos and c-jun in CKs. /// BK stimulated [3H]thymidine incorporation and p42/p44 MAPK phosphorylation in a time- and concentration-dependent manner. /// "These results demonstrate that in CKs, BK-stimulated phosphorylation of p42/p44 MAPK is mediated through the activation of BK B2 receptors and leads to cell proliferation.. " /// Bradykinin-stimulated p42/p44 MAPK activation associated with cell proliferation in corneal keratocytes.. /// "This study was to investigate the mitogenic effect of BK on rabbit CKs linked to activation of p42/p44 mitogen-activated protein kinase (MAPK), assessed by [3H]thymidine incorporation and Western blotting analysis, respectively.

We have previously shown that the activation of p42/p44 MAPK required for transduction of mitogenic signaling is associated with a rapid nuclear translocation of these kinases. /// We therefore conclude that the MAPK nuclear translocation requires both activation of the p42/p44 MAPK module and neosynthesis of short-lived proteins that we postulate to be nuclear anchors.. /// "In this study, we have demonstrated that activation of the p42/ p44 MAPK pathway was necessary and sufficient for triggering nuclear translocation of p42 and p44 MAPK. " /// Growth factor-induced p42/p44 MAPK nuclear translocation and retention requires both MAPK activation and neosynthesis of nuclear anchoring proteins.. /// " Mitogen-activated protein kinases (p42/p44 MAPK, also called Erk2 and Erk1) are key mediators of signal transduction from the cell surface to the nucleus. " /// "Indeed, inhibitors of protein synthesis abrogate nuclear accumulation in response to serum and accelerate p42/p44 MAPK nuclear efflux under conditions of persistent p42/p44 MAPK activation. " /// "In contrast, inhibition of targeted proteolysis by the proteasome synergistically potentiated p42/p44 MAPK nuclear localization by nonmitogenic agonists and markedly prolonged nuclear localization of p42/p44 MAPK after mitogenic stimulation. " /// "In addition, we have shown that this nuclear accumulation of p42/p44 MAPK required the neosynthesis of short-lived proteins. " /// "First, addition of the MEK inhibitor PD 98059, which blocks activation of the p42/p44 MAPK pathway, impedes the nuclear accumulation, whereas direct activation of the p42/p44 MAPK pathway by the chimera DeltaRaf-1:ER is sufficient to promote nuclear accumulation of p42/p44 MAPK.
