KRT19 and colonic neoplasm: We also checked EMT and stemness marker expression and found that, upon KRT19 knockdown, expression of EMT and stemness marker genes was downregulated in colon cancers, whereas the expression of markers was upregulated in breast cancers upon knockdown of KRT19, relative to their respective control (scramble) cells (Figure 2e,f), suggesting differential roles of KRT19 in various cancer cells.
