In nasopharyngeal carcinoma (NPC) CREB1 and SRGN are increased while miR-148a-5p is decreased. Silencing of SRGN and CREB1, and miR-148a-5p overexpression represses NPC tumor progression. The authors show that CREB1 promotes SRGN expression by targeting its promoter. In NPC, FoxO1 binds to miR-148a-5p, and miR-148a-5p targets CREB1. FoxO1 knockdown abolishes the downregulation of CREB1 and SRGN induced by STAT3 silencing. In summary, STAT3 regulates SRGN and promotes the growth and metastasis of NPC through the FoxO1-miR-148a-5p-CREB1 axis.
