The presence or absence of such sites may alter signaling pathways, stimulusdependence, or the development of particular protein complexes.
If the retrovirus gets inserted into a region that activates an oncogene or inactivates a tumor suppressor or repair gene, the insertion may alter signaling pathways and contribute to tumor development or progression by insertional mutagenesis.
How EMT-like effects via cytoskeletal machinery such as actin may alter signaling pathways when combined with classical EMT inducers (growth factors such as EGF or the TGFβ family) is unknown, and this information would provide important clues as to how cross-modulation may occur.
The slowing of the EPSC kinetics was not investigated in detail and the EPSC amplitudes were not compared, but it is consistent with the idea that changes in the properties of GCs, as we have observed, may alter signaling at downstream parallel fiber PC synapses.
Genes that we have characterized in this study for E2-regulated alternative splicing provide glimpse of how these alternative-spliced products may alter signal transduction as well as response to therapy.
Oxidative stress is believed to be the common cause of endothelial dysfunction [ 37] as it can cause damage to proteins, deoxyribonucleic acid, lipids and hence may alter signal transduction in cells.
Overall, this suggests that arthritic macrophages may have altered signalling patterns when compared to other cell types, and IL-10 may have both anti- and pro-inflammatory functions in RA.
Immortalized cells may therefore have altered signalling that activates NFκB in a MEK/ERK-dependent manner by TNFα.
The most important implication is that molecular therapies under investigation should be evaluated for their ability to influence EpCAM-mediated signaling pathways, as recent studies suggest that monoclonal antibodies targeting EpCAM may alter EpCAM signaling [ 53].
Lack of pendrin expression leads to epithelial cell stretching and luminal acidification, which may alter cell signaling to result in the observed retarded development of stria vascularis.
