Lithium chloride induces mesenchymal‑to‑epithelial reverting transition in primary colon cancer cell cultures.

ABSTRACT: Epithelial‑to‑mesenchymal transition (EMT) confers stem cell‑like phenotype and more motile properties to carcinoma cells. During EMT, the expression of E‑cadherin decreases, resulting in loss of cell‑cell adhesion and increased migration. Expression of Twist1 and other pleiotropic transcription factors, such as Snail, is known to activate EMT. We established primary colon cancer cell cultures from samples of operated patients and validated cultures by cytogenetic and molecular biology approaches. Western blot assay, quantitative real‑time PCR and immunofluorescence were performed to investigate the expression of E‑cadherin, vimentin, β‑catenin, cytokeratin‑20 and ‑18, Twist1, Snail, CD44, cyclooxygenase‑2 (COX2), Sox2, Oct4 and Nanog. Moreover, cell differentiation was induced by incubati
