Rafts of epithelial cells
WebEpithelium, endothelium and mesothelium are three types of epithelial cell layers that line your internal organs, body cavities and form the outer layer of your skin. Epithelium generally lines pathways that are open to the external environment, such as your respiratory tract and digestive system. WebJul 8, 2024 · Kajiwara et al. show that Src-transformed cells underwent basal delamination by Src activation within lipid rafts during epithelial cell competition. This process is mediated by Src-activating scaffold proteins. Src activation in lipid rafts confers resistance to apical extrusion and invasive potential on epithelial cells to promote carcinogenesis.

WebJul 12, 2024 · Epithelial cells, which line the surfaces and organs of the body, can protect themselves against cancer by removing unhealthy or abnormal cells through a mechanism known as “apical extrusion,” where the damaged cells are forcibly removed from the cell layer by the surrounding healthy cells.
WebMar 15, 2005 · Polarised epithelial cells direct distinct cargos to their apical and basolateral surfaces, and lipid rafts probably play an important role in polarised membrane trafficking. For most of the GPI-anchored proteins and apical transmembrane proteins, N-glycans or O-glycans attached to the proteins are thought to be the apical sorting signals.
