Quercetin is considered asa potential chemopreventive agent due to its involvement in suppression of oxidative stress, proliferation andmetastasis. In this study, the expression of CD133/CD44 in esophageal carcinomas and Eca109/9706 cells wasexplored. In immunoflurorescence the locations of CD133+ and multidrug resistance 1 (MDR 1)+ in the sameE-cancer cells were coincident, mainly in cytomembranes. In esophageal squamous cell carcinomas detected bydouble/single immunocytochemistry, small CD133+ cells were located in the basal layer of stratified squamousepithelium, determined as CSLC (cancer stem like cells); CD44+ surrounding the cells appeared in diffuse pattern,and the larger CD44+ (hi) cells were mainly located in the prickle cell layer of the epithelium, as progenitor cells.In E-cancer cells exposed to nanoliposomal quercetin (nLQ with cytomembrane permeability), down-regulationof NF-κBp65, histone deacetylase 1 (HDAC1) and cyclin D1 and up-regulation of caspase-3 were shown byimmunoblotting, and attenuated HDAC1 with nuclear translocation and promoted E-cadherin expression weredemonstrated by immunocytochemistry. In particular, enhanced E-cadherin expression reflected the reversedepithelial mesenchymal transition (EMT) capacity of nLQ, acting as cancer attenuator/preventive agent. nLQacting as an HDAC inhibitor induced apoptotic cells detected by TUNEL assay mediated via HDAC-NF-κBsignaling. Apoptotic effects of liposomal quercetin (LQ, with cytomembrane-philia) combined with CD133antiserum were also detected by CD133 immunocytochemistry combined with TUNEL assay. The combinationcould induce greater apoptotic effects than nLQ induced alone, suggesting a novel anti-CSC treatment strategy.}, keywords = {CSC marker,nanoliposomal/liposomal quercetin,human esophageal SCC,treatment strategy}, url = {https://journal.waocp.org/article_29977.html}, eprint = {https://journal.waocp.org/article_29977_dd27874453ae408c0780b7391ebf04dd.pdf} }
