ZEB1 and cancer: In Figure 4, the transcription factor ZEB1 (zinc-fingered E-box binding homeobox 1), best known for its involvement in mesenchymal–epithelial transition processes, cancer cell differentiation, progression, and metastasis [45,113] through the regulation of proteins such as SALL4 and GATA3 [114,115], which were also found to be related in the network, is the hub with the highest number of interactions.
