| Abstract: [Objective] To investigate the effect of resveratrol (RES) on the polarization state of tumor-associated macrophage and its impact on the metastatic ability of nasopharyngeal carcinoma (NPC), and to explore its molecular mechanisms.[Methods] (1) Induction of M2-type macrophages: phorbol 12-myristate 13-ace-tate (PMA) was used to induce M0 macrophages from human leukemia monocytes THP-1, flow cytometry (FCM) was employed to detect M0 macrophages marked by CD11B; NPC CNE2 cells were co-cultured with M0 macrophages, FCM was used to detect M2-type macrophages marked by CD163 and CD206, and quantitative real-time PCR (qPCR) was used to detect IL-10 and TGF-β1. (2) Effects of RES on the polarization state of macrophages: M2-type macrophages were treated with 40 μmol/L RES for 24 h, FCM was used to detect the proportion of M2-type macrophages expressing CD163 and CD206, as well as M1-type macrophages expressing CD80 and CD86; qPCR was used to detect the changes in CD163, TGF-β1, and IL-10;Western blot was used to detect the expression levels of PI3K and p-AKT proteins. (3) Effects of RES on the metastasis ability of NPC cells by regulating macrophages: NPC cells were cultured for 24 h in M2-CM and RES-M2-CM respectively, Transwell assay was used to detect the migration and invasion abilities, Western Blot was used to detect the expression levels of MMP-2, MMP-9, E-cadherin, Vimentin proteins in the two groups of cells. [Results] (1) Successful induction of M2-type macrophages: during the process of PMA-induced THP-1 cell transformation, changes in cell morphology were observed under an optical microscope, and FCM detection revealed an increase in cells expressing CD11B; after 24 h of co-culture with CNE2-CM, FCM detection found an increase in the number of M2-type macrophages expressing CD163 and CD206, and qPCR detection suggested elevated expression of CD163, TGF-β1, and IL-10 cytokines. (2) After RES treatment of M2-type macrophages for 24 h, the number of macrophages expressing CD163 and CD206 decreased(P<0.001), while the number of macrophages expressing CD80 and CD86 increased (P<0.01); the expression levels of CD163, TGF-β1, and IL-10 decreased(P<0.01), Western blot experiments revealed a decrease in the expression levels of PI3K and p-AKT proteins(P<0.05). (3) The Transwell experiment revealed that the invasive and migratory abilities of NPC cells were enhanced in witch co-cultured with M2-CM but were weakened in witch co-cultured with RES-M2-CM(P<0.001). The Western Blot experiment showed that the expression of E-cadherin in NPC cells decreased in witch co-cultured with M2-CM but increased in witch co-cultured with RES-M2-CM; the expression levels of Vimentin, MMP-2, and MMP-9 increased in witch co-cultured with M2-CM but decreased in witch co-cultured with RES-M2-CM(P<0.05).[Conclusion] RES can reverse M2-type macrophages into M1-type macrophages through the PI3K/AKT signaling pathway; RES can suppress the migration of nasopharyngeal carcinoma by inhibiting EMT via increasing the expression level of E-cadherin and decreasing the expression level of Vimentin, it can also inhibit the invasion ability of NPC by down-regulating the expression levels of MMP-2 and MMP-9. |
