EGF(R)-mediated drug delivery
- First please see this paper for background info on EGF(R) targeting here.
- The aim of this wiki document is to review the characterization of cancerogenic mutations occuring in multiple receptor-associated tyrosine kinase proteins targeting the EGF receptor and perhaps cholesterol based lipid rafts including stearic acid (monosaturated) and polysaccharide fatty acids ligands.
- Breast cancer epithelial stem cells switching and the risks of EGF(R)-targeted phosphorylation:
- Epithelial Stem Cells: Turning over New Leaves (Rockefeller University)
- Receptor-associated tyrosine kinase signaling (SH2/SH3) for targeted drug delivery to epithelial stem cells membranes?
- Is programmed cell-death from cell-specific DNA based gene regulation via p53 gene/protein is leading to cell apoptosis? If so, could DNA programmed apoptosis result from aggregated nanoparticles to epithelial/endothelial stem cells membranes (ie: immunoglobin-like domain receptor) ?
- Glycoproteins role in programmed cell division acting as a master toll-like switch for receptor-associated drug delivery? (ie: EGFR)
- On lipid rafts: "Plasma membranes are heterogeneous and contain microdomains for lipid composition and receptors, especially in T and B lymphocytes and mast cells. Rafts are a way of concentrating receptors, the lipids and lipid tethered proteins together to provide the elements needed to activate secondary signals."

- Is the p53 gene dependent on genetical inheritance (DNA-protein interactions) to make epithelial stem cells vulnerable to cancerogenic mutations ?
Src homology domains, SH2, SH3, PH (Pleckstrin Homology domain), cyclosporamide (a alkylating agent used in cancer therapy)
