The importance of Zeb1 in IL-1β-induced EMT in colon cancer cells is further highlighted in Zeb1 knockdown HCT-116 cells, which display a close association between the lack of EMT and the disappearance of IL-1β-induced repression of E-cadherin transcription in these cells (Figure 6). The gene discussed is IL1B; the disease is colonic neoplasm.
