In the present study, we investigated the involvement of 5-LO Xand CysLT1 signaling in the process of EGF-induced cell migration by using small molecule inhibitors.
In this study, we found that 5-lipoxygenase (5-LOX) is activated in the process of EGF-induced cell migration, and that leukotriene C4 (LTC4) produced by 5-LOX mediated the second wave of Rac1 activation, as well as cell migration.
This can be investigated further by deleting the process of receptor degradation from our EGF model to generate a realistic model of the NGF receptor TrkA system.
Recently, numerous studies demonstrated that, some cytokines like TGF-β, HGF and EGF can induce the process of EMT [ 7- 9].
Although the work presented here does not affect our previous conclusions, it does take our previous work another step forward by considering the Rap1 pathway to show that although the SOS feedback loop is indeed redundant, the process of receptor degradation is actually essential in EGF signalling.
In the process of gastric cancer progression, BCL6 is decreased by HB-EGF-CTF signalling and the ubiquitin/proteasome pathway.
The IGF-I and EGF downstream signaling pathways are closely involved in the process of progression to therapy resistant disease.
We suggest a model for the mechanism regulating the second EGF-induced wave of Rac1 activation in the process of cell migration, as shown in Figure 6.
Furthermore, Src and EGF receptor reciprocally interact and appear to cooperate in the process of malignancy [ 5].
To examine the effects of low molecular weight heparins (LMWHs) on extravillous trophoblast (EVTC) invasiveness and on EVTC expression/secretion of heparin binding-EGF (HB-EGF) and cystein-rich angiogenic inducer 61 (Cyr61), both of which are involved in the process of EVTC invasion.
EGF can promote proliferation, repair, and migration of epithelial cells in the small intestine during the process of regeneration after its damage [ 30, 65].
