Abstract

As an oncogene, plasmacytoma variant translocation 1 (PVT1) has been found to be highly expressed in several cancers. However, its specific role in lung adenocarcinoma (ADC) has not been fully elucidated. In this study, the expression of PVT1, miR-378c, and solute carrier family 2 member 1 (SLC2A1) was determined by quantitative real-time PCR and western blot. Dual-luciferase reporter assay was used to explore the relationship between PVT1 and miR-378c, as well as miR-378c and SLC2A1. The effects of PVT1 on the lung ADC cells proliferation, invasion, and migration were detected using MTT, wound-healing, and transwell assays. The results revealed that PVT1 was highly expressed in lung ADC cells, and the overexpression of PVT1 promoted the proliferation, migration, and invasion of lung ADC cells. In lung ADC cells, PVT1 negatively regulated miR-378c expression, and miR-378c negatively regulated SLC2A1 expression through binding to its 3′-untranslated coding regions. Knocking down of PVT1 inhibited the abilities of cell proliferation, migration, and invasion, while miR-378c inhibitor or SLC2A1 Vector diminished the effect. Together, silencing PVT1 downregulated SLC2A1 expression via targeting miR-378c, and then repressed lung ADC cells growth, migration, and invasion.
