EMT, Epithelial-Mesenchymal Transition: Click to Expand ⟱
Source:
Type:
Biological process in which epithelial cells lose their cell polarity and cell-cell adhesion properties and gain mesenchymal traits, such as increased motility and invasiveness. This process is pivotal during embryogenesis and wound healing. Hh signaling pathway is able to regulate the EMT. Snail, E-cadherin and N-cadherin, key components of EMT; EMT-related factors, E-cadherin, N-cadherin, vimentin; The hallmark of EMT is the upregulation of N-cadherin followed by the downregulation of E-cadherin.
EMT is regulated by various signaling pathways, including TGF-β, Wnt, Notch, and Hedgehog pathways. Transcription factors such as Snail, Slug, Twist, and ZEB play critical roles in repressing epithelial markers (like E-cadherin) and promoting mesenchymal markers (like N-cadherin and vimentin).
EMT is associated with increased tumor aggressiveness, enhanced migratory and invasive capabilities, and resistance to apoptosis.
