Objective To evaluate the effect of glycogen synthase 1 (GYS1) on the proliferation of non-small cell lung cancer cells. Methods The relative expression levels of GYS1 mRNA in normal human bronchial epithelial cell line HBE cells, non-small cell lung cancer cell lines NCI-H661 and NCI-H1299 were quantitatively detected by quantitative real-time fluorescence PCR (qRT-PCR). The NCI-H1299 cells overexpressing GYS1 were utilized to establish the GYS1 overexpression cell model. MTT assay and EdU proliferation experiment were adopted to evaluate the cell proliferation ability, and plate clone formation assay was employed to assess the cell clone formation ability. Results The expression levels of GYS1 mRNA in human non-small cell lung cancer cells NCI-H661 and NCI-H1299 were significantly higher than that in normal human bronchial epithelial cell HBE (both P < 0.001). The relative expression levels of GYS1 mRNA and protein were significantly up-regulated in the NCI-H1299-GYS1 overexpressing cells (both P < 0.001). Overexpression of GYS1 remarkably promoted the proliferation and clone formation of NCI-H1299 cells (both P < 0.001). Conclusions GYS1 is highly expressed in non-small cell lung cancer. Overexpression of GYS1 promotes the proliferation of non-small cell lung cancer cells.
