Although accumulating evidence had revealed that NFAT1 has oncogenic characteristics, the role of this molecule in melanoma cells remains unclear. Previous studies proved that CD147 plays a crucial function in melanoma cell metastasis and invasion through matrix metalloproteinase 9 (MMP‐9) expression; however, the details of how CD147 regulates MMP‐9 expression remain elusive. In this study, we demonstrated that CD147 and NFAT1 are overexpressed in the tissues of patients with primary and metastatic melanoma, which has shown a positive correlation. Further, we observed that CD147 regulates NFAT1 activation through the [Ca 2+ ]i‐calcineurin pathway. Knockdown of NFAT1 significantly suppresses melanoma metastasis, and we demonstrated that CD147 affects melanoma metastasis in an NFAT1‐dependent manner. Moreover, we verified that NFAT1 directly binds to MMP‐9 promoter. Inhibition of CD147 expression significantly abrogates MMP‐9 promoter luciferase gene reporter activity as well as NFAT1 association with MMP‐9 promoter. Taken together, this study demonstrated that CD147 affects MMP‐9 expression through regulating NFAT1 activity and provided a novel mechanism by which NFAT1 contributes to melanoma metastasis through the regulation of MMP‐9.
