ZEB1 and colorectal carcinoma: Furthermore, multiple oncogenic signaling cascades, including Wnt/β-catenin, TGF-β, NF-κB, MEK-ERK, JAK/STAT3, and HIF-1α, converge on ZEB1 to amplify its transcriptional and epigenetic activity, positioning ZEB1 as a nodal integrator of extracellular cues and epigenetic reprogramming in CRC metastasis.
