It enables epithelial cancer cells to detach from the primary tumor mass and gain survival advantages in the bloodstream, significantly contributing to the spread of circulating tumor cells. Notably, epithelial-tomesenchymal transition is not a binary process but rather leads to the formation of a wide range of cell subpopulations characterized by the simultaneous expression of both epithelial and mesenchymal markers. Therefore, analyzing the modulation of EMT hallmarks during the conversion from healthy cells to metastatic cancer cells, which acquire stem mesenchymal characteristics, is of particular interest. This study investigates the expression of a panel of epithelial-to-mesenchymal transition-related genes in healthy cells, primary and metastatic cancer cells, and in mesenchymal cell lines, derived from various tissues, including the lung, colon, pancreas, skin, and neuro-ectoderm, with the aim of identifying potential cut-off values for assessing cancer aggressiveness. Interestingly, we found that the expression levels of CDH1, which encodes the epithelial marker E-cadherin, CDH5, encoding vascular endothelial cadherin, and the epithelial-to-mesenchymal transitiontranscription factor ZEB1, effectively distinguished primary from metastatic cancer cells. Additionally, our data suggest a tissue-specific signature in the modulation of epithelial-tomesenchymal transition markers during cancer progression. Overall, our results underscore","cbCaihI3a3TtYSyB","https://ap.wps.com/l/cbCaihI3a3TtYSyB","pdf",3601685,"English","# Introduction\n## EMT in physiology and pathology\n## EMT mechanisms and cancer metastasis\n# Results\n## Cut-off-based discrimination of cell types\n## Tissue-specific EMT marker signatures\n# Discussion\n## Clinical relevance of EMT markers\n## Implications for aggressiveness and therapy responsiveness","[{\"question\":\"Why is epithelial-to-mesenchymal transition important in cancer progression?\",\"answer\":\"EMT enables epithelial cancer cells to detach from the primary tumor, gain survival advantages in the bloodstream, and increase aggressiveness, motility, and invasiveness, supporting metastasis formation.\"},{\"question\":\"Is EMT treated as a binary switch in the study?\",\"answer\":\"No. EMT is presented as a non-binary process that generates a spectrum of cell subpopulations expressing both epithelial and mesenchymal markers simultaneously.\"},{\"question\":\"Which markers does the study report as distinguishing primary from metastatic cancer cells?\",\"answer\":\"The expression levels of CDH1 (E-cadherin), CDH5 (vascular endothelial cadherin), and the EMT transcription factor ZEB1 effectively distinguish primary from metastatic cancer cells.\"}]","The Clinical Relevance of Epithelial-to-Mesenchymal Transition Hallmarks - A Cut-Off-Based Approach in Healthy and Cancerous Cell Lines | PDF",1790160623]
