The antiproliferative and proapoptotic role of ERB in colon tumors have been described, and it is believed that those effects may be due to the combination of several events such as regulation of the cell cycle, decrease in the expression of oncogenes such as MYC and MYB, regulation of the anti-inflammatory response and an increase in DNA repair capacity (47). The gene discussed is MYB; the disease is colonic neoplasm.
