Our present findings reveal that knockdown of CCL20 attenuated AKT and STAT3 signaling and reduced MMP2/9 secretion, suggesting the effect of CCL20 might result from its function in activating oncogenic signaling pathways (STAT3, AKT) and enhancing the expression of metastasis-related MMP2/9, thus promoting the tumor progression of PC. This evidence concerns the gene CCL20 and neoplasm.
