Methyltransferase SETD2 inhibits tumor growth and metastasis via STAT1-IL-8 signaling-mediated epithelial-mesenchymal transition in lung adenocarcinoma.

ABSTRACT: Lung adenocarcinoma (LUAD) is a major subtype of non-small-cell lung cancer, which is the leading cause of cancer death worldwide. The histone H3K36 methyltransferase SETD2 has been reported to be frequently mutated or deleted in types of human cancer. However, the functions of SETD2 in tumor growth and metastasis in LUAD has not been well illustrated. Here, we found that SETD2 was significantly downregulated in human lung cancer and greatly impaired proliferation, migration, and invasion in vitro and in vivo. Furthermore, we found that SETD2 overexpression significantly attenuated the epithelial-mesenchymal transition (EMT) of LUAD cells. RNA-seq analysis identified differentially expressed transcripts that showed an elevated level of interleukin 8 (IL-8) in STED2-knockdown LUAD cells, wh
