Objective: This study aimed to examine the effects of apigenin (API) on the proliferation, migration, and invasion of human tongue squamous cell carcinoma Tca8113 cells and explore its probable mechanisms.
Methods: After treating Tca8113 cells with API, the cell proliferation, migration, and invasivecapacities were identified by te-trazolium salt colorimetry(MTT) assay, cell scratch test, and Transwell chamber test. Cellular immunofluorescence staining was used to localize mitogen-activated protein kinase 1 (MAPK1) and extracellular regulated protein kinase (ERK) 1/2 proteins. Western blot was used to detect the variations of the related protein expression levels.
Results: ① Through the MTT assay, API significantly inhibited cell proliferation (P<0.01). ②In the cell scratch test, the dis-tance of lateral migration after the API treatment was significantly shorter compared to the control group (P<0.01). ③The inva-sion rate in the lower chamber of the Transwell chamber was lower in the API group (P<0.01). ④ Cellular immunofluores-cence staining presented that the total-MEKK1 was localized in the cytoplasm, p-MEKK1 was localized in the nuclear mem-brane and cytoplasm, and p-ERK1/2 was localized in the cytoplasm and nucleus. ⑤ After API was applied to cells, the expres-sions of p-MEKK1 and p-ERK1/2 proteins significantly reduced (P<0.01).
Conclusion: Apigenin(API) significantly inhibits the proliferation, migration, and invasion of Tca8113 cells and its mecha-nism may be associatedwith the MAPK signaling pathway.
