Because c-Myc may affect immortalization while cyclin D1 elicits transformation, agents that target c-Myc and cyclin D1 can be good chemopreventive agents [ 11].
Furthermore, chronic TGF-β exposure can elicit phenotypic transformation under certain conditions, resulting in the acquisition of mesenchymal-like transformation of mammary epithelial cells [ 47], or myofibroblast characteristics in stromal cells [ 48].
In the present studies, we routinely incubated the enzyme overnight with an excess of pteridine to elicit the transformation from an enzyme that binds BH4 monophasically to a species that has one pterin bound (quasi- irreversibly.
Given that the vector configuration which promoted leukaemia in the London and Paris clinical trials would not be predicted to elicit malignant transformation in the assay (and indeed did not lead to leukaemia in this new set of experiments), we are unsure of how informative the data from this experiment will be.
Efforts have been made on both fronts, searching for deregulated genes in human tumor samples and screening for genes capable of eliciting cell transformation in experimental systems.
More direct evidence was presented by Kolligs et al (2000), who demonstrated that overexpression of wild-type plakoglobin elicits neoplastic transformation in a rat kidney epithelial cell line.
Such studies have highlighted the importance of Ras signaling in eliciting cancerous transformation upon defects in epithelial polarity and membrane trafficking (Pagliarini and Xu, 2003; Chi et al., 2010).
CDK4 and PIKEs are involved concomitantly in cancer pathogenesis by cooperatively targeting the PI3K/AKT and Rb1 pathway, although some studies have shown that overexpression of PIKEs alone can elicit NIH3T3 cell transformation [ 117, 128].
Thus, we hypothesized that H. pylori infection might elicit the malignant transformation of gastric epithelial cells, leading to a pro-inflammatory response and consequently the dysfunction of miRNAs in fibroblasts, which in turn promotes tumor development.
Shallow EVT invasion elicits incomplete vascular transformation and reduces uteroplacental blood flow that presages adverse pregnancy outcomes.
