Cav-1 promote lung cancer cell proliferation and invasion through lncRNA HOTAIR

Objectives: Lung cancer is one of the most common malignant tumors worldwide, and its morbidity and mortality rates continue to rise. The role of lncRNAs in lung cancer has become an emerging area of research. Materials and methods: The expression of CAV-1 and HOTAIR was determined in lung cancer tissues and cell lines by western blot and RT-qPCR. Cell proliferation, migration and invasion were analysed in lung cell following knockdown or overexpression of CAV-1 or HOTAIR by transfection with small interfering RNA (siRNA) or plasmid. Results: The expression of CAV-1 and HOTAIR in lung cancer tissues and cell lines was higher than in normal lung tissue or normal lung cell lines. We discovered that CAV-1 could regulate cell proliferation, migration and invasion. At the same time, CAV-1 could regulate the expression of HOTAIR. In addition, knockdown of the expression of HOAIR partially reverses the promotion of cell viability and invasion induced by CAV-1. Conclusions: Our results indicated that CAV-1 coordinate the lung cancer through HOTAIR. And HOTAIR may become a novel target for lung cancer therapy.
