For instance, epigenetic mechanisms have been implicated in the programming of cell fate and differentiation [43] [50], in defining ultimate activity levels of specific functional systems [22], [24], and in mediating environmental modulation of genetically-based developmental programs [22], [24], [42], [51], [52].
Besides a search for naturally occurring tumor-like lesions and neoplasms in molluscs, we used modulation of gene expression by genetically engineered constructs bearing foreign genes, the yeast transcriptional activator gal4 gene or the agrobacterial rol oncogenes, in sea urchin embryos and sea urchin embryonic cells.
Modulation of the AA pathways genetically or pharmacologically, with aspirin or bioactive AA-mimetics influences cholesterol metabolism including reverse cholesterol transport.
Hence, modulation of DNA-damage responses genetically with mutations or chemically with small molecule inhibitors of DNA-repair enzymes could selectively enhance the sensitivity of cancer cells to DNA-damaging therapies resulting in SC.
Modulation of innate immune response by genetically ablating MyD88 partially rescued the progression of PC loss and motor incoordination in MPI118Q/118Q mice in its early stage.
Taken together, these findings suggest that a (genetically determined) modulation of VEGF-A levels in the tumour microenvironment could impact the response of tumours to metronomic therapy.
For these reasons, a (genetically determined) modulation of VEGF-A in the tumour microenvironment could have a decisive role in the response of a tumour to metronomic therapy.
Moreover, modulation of the neuroinflammtory response by genetically ablating myeloid differentiation factor 88 (MyD88), a major adaptor molecule essential for Toll-like receptor (TLR) signaling pathway, significantly delayed the progression of PC degeneration in the MPI118Q/118Q mice.
Conditional tissue-specific modulation of genes using Cre/loxP recombination in genetically engineered mice provides an enormous leap forward to study gene function in detail yet requires detailed knowledge of gene regulation and expression patterns.
The experimental strategies applied include pharmacological modulation of the function of platelets and various constituents of the blood coagulation cascade, as well as the use of genetically modified animals exhibiting altered expression or activity of those components.
Because endothelial cells are considered to be genetically stable [ 2], modulation of angiogenic processes is considered to be a promising area for cancer therapy.
