When HT-29 or HCT116 cells are co-cultured with TAMs (THP-1 cells stimulated by conditioned medium from a CRC cell line), TAM derived IL-6 activates the JAK2/STAT3 pathway, which results in increased FoxQ1 expression, leads to the production of CCL2 and promotes the recruitment of macrophages, thus enhancing the migration and invasion of CRC cells (59). The gene discussed is FOXQ1; the disease is colorectal carcinoma.
