ZNF692 promotes proliferation and cell mobility in lung adenocarcinoma

By analyzing The Cancer Genome Atlas (TCGA) datasets, we discovered that the zinc finger protein 692 (ZNF692) were over-expressed in Lung adenocarcinoma (LUAD) tissues compared to adjacent non-tumor tissues (P < 0.0001). In this study, we investigated the function of ZNF692 in the progression of LUAD. We found that ZNF692 knockdown inhibited LUAD cells proliferation, migration, and invasion both in vitro and in vivo. And LUAD cell apoptosis was induced following the down-regulation of ZNF692. Our results show that ZNF692 is over-expressed in LUAD tissues compared to adjacent normal tissues, and hyper-expression of ZNF692 in LUAD is an independent risk factor for worse overall survival in LUAD patients (HR: 8.800, 95%CI: 1.082-71.560, P = 0.042) by Tissue Microarray stain assay (TMA). GO analysis indicated that most genes were enriched in metabolic process which were associated highly with ZNF692 levels. Collectively, our results suggested that ZNF692 may serve as a potential oncogene and biomarker in LUAD by influencing cell metabolism.
