ABSTRACT
@#Objective To investigate the expression of C-C chemokine ligand 5(CCL5) in head and neck squamous cell carcinoma(HNSCC),and explore the effect of CCL5 on the biological characteristics of laryngeal carcinoma cells.Methods Gene Expression Profiling Interactive Analysis(GEPIA) database was used to investigate the expression of CCL5 in HNSCC.The laryngeal carcinoma cells TU177 were transfected with siRNA(siRNA group),and the control(NC) group was set up.The cell proliferation,migration,cycle and apoptosis of each group were detected by CCK8 assay,cell scratch test and flow cytometry respectively.RT-PCR and Western blot were used to detect the knock-down efficiency of CCL5 and the mRNA transcription and protein expression of multidrug resistance protein 2(MRP2) and bcl-2-associated x protein(Bax).Results The expression of CCL5 in HNSCC was higher than that in normal tissues(P <0.05).Compared with NC group,siRNA showed higher knock-down efficiency(t=12.898 and 22.656 respectively,each P <0.01);siRNA interference with CCL5 inhibited the proliferation and migration of laryngeal carcinoma cells,and promoted the late apoptosis of laryngeal carcinoma cells and the expression of apoptosis protein Bax(t=2.600~11.667,each P <0.05).Conclusion CCL5 was highly expressed in HNSCC,while siRNA interference with CCL5 inhibited the proliferation,migration and promoted apoptosis of laryngeal carcinoma cells TU177 by up-regulating the expression of Bax,which laid a foundation of the possibility of CCL5 as a new target for the treatment of laryngeal carcinoma.
