    題名: ADAM9 drives immunosuppressive environment for lung tumor progression

    摘要: Cancer cells develop the immune suppressive tumor environment, but the underlying molecular mechanism for it is still elusive. Here, we demonstrated that ADAM9 contributed to lung tumor progression and promoted IFN-related gene expression in lung cancer cells that participated in immune regulation in the tumor environment. ADAM9 knockout (KO) lung cancer cells reduced lung cancer metastasis with a decrease in neutrophil infiltration and an increase in CD8+ T cell infiltration. By performing the genome-wide approach to explore ADAM9-regulated genes in lung cancer cells, we revealed that ADAM9 regulated cytokine production and lymphocyte activation. It enhanced the master transcription factor of IFN signaling, STAT1 activation in lung cancer cells. Moreover, ADAM9 promoted IL6/IL6 receptor-STAT3 axis signaling that lead to suppression of IL12p40 secretion and MHC class II expression in dendritic cells and macrophages. Notably, we found that type I IFN related-proteins and steroid biosynthesis-related proteins were related to ADAM9-mediated STAT signaling activation by LC-MS/MS analysis. We demonstrated that ADAM9 created an immune suppressive environment by regulating IFN signaling for tumor progression.
