It has been reported that TGF-β markedly suppresses the cytotoxic function of CD8 + T cells through transcriptional downregulation of genes encoding key proteins, such as perforin, granzymes, and cytotoxins (16, 17). TGF-β affects CD4 + T cell differentiation and function by inducing Treg conversion (17, 18).

The objective of this study was to examine the effect of TGF-β on possible EMT and stem cell markers in the induction of EMT and stemness acquisition. Moreover, we investigated whether the mechanism of EMT and stemness acquisition was related to the activation of possible EMT and stem cell markers by epigenetic change of related genes.
