Transcription factor STAT1 promotes the proliferation, migration and invasion of nasopharyngeal carcinoma cells by upregulating LINC01160

Mini abstract In this study we found that the transcription factor STAT1 can promote proliferation, motility and invasion of nasopharyngeal carcinoma cells by upregulating the expression of LINC01160. Aim: To investigate the role of LINC01160 in nasopharyngeal carcinoma (NPC). Materials & methods: Using NPC cells CNE-2 and HNE-2 in vitro, we performed quantitative PCR to determine mRNA expression and western blotting to determine protein expression. CCK-8, transwell, flow cytometry and wound healing assays were done to examine the function of LINC01160 and STAT1. Chromatin immunoprecipitation PCR (ChIP-PCR) confirmed that STAT1 combines with the LINC01160 promoter region. Xenograft experiments were used to verify the role of STAT1 and LINC01160 in vivo. Results: LINC01160 is upregulated in NPC and can promote a malignant cell phenotype. STAT1 is a transcription factor of LINC01160 and can promote a malignant cell phenotype through upregulating LINC01160 expression. Conclusion: STAT1 can promote a malignant cell phenotype by upregulating LINC01160.
