On the other hand, Smad transcription factors are key mediators of the biological effects of transforming growth factor β1 in PSC, stimulating transformation to a myofibroblastic phenotype and increased ECM synthesis.
The pro-fibrotic cytokine, Transforming Growth Factor β1 (TGF-β1), stimulates transformation of human lung fibroblasts into myofibroblasts that produce collagen and other extracellular matrix components, a transformation process blocked by JNK inhibition [24].
These centers are the most probably formed as a result of thermally stimulated transformation of radiation-induced defects at the nc-Si SiO2 nc-Si SiO2
Even in a first best world, climate policy design needs to navigate a tradeoff between making commitments that are sufficiently credible to stimulate transformation and retaining flexibility to adjust.
Furthermore, interactions between the rhizosphere and earthworms stimulated transformation of soil P and guano P; the proportional importance of soil microbial biomass P, organic-P and more soluble P fractions were substantially modified.
BRAFV600E constitutively activates the RAS/RAF/MEK/ERK signalling pathway, and stimulates transformation of immortalised melanocytes (Wellbrock et al, 2004).
Activated PAK1 enhances cell survival and migration via the AKT pathway, and stimulates transformation through the Ras/Raf/ERK/MAPK pathway.
RhoA has been implicated in virtually all stages of cancer progression: for example, in vitro, constitutively active RhoA can stimulate transformation [ 115].
It may play a role during tumor cell proliferation and survival; for example, in vitro, constitutively active RhoA was shown to stimulate transformation (Vega and Ridley, 2008).
30, 32 Although some believe that selective destruction of abnormal melanocytes is a means for reducing the number of cells at risk for malignant transformation, it is also possible that laser or other treatments may inadvertently stimulate transformation to melanoma.
We showed here that pulse exposure to oxaliplatin stimulated transformation of HepG2 and MHCC97L HCC cells from a typical epithelial phenotype to a spindle-shaped mesenchymal phenotype, accompanied by the loss of E-cadherin and upregulation of N-cadherin and vimentin.
