Abstract
Objective To study the potential mechanism of PLK2 and p21 affecting the occurrence and development of osteosarcoma.Methods The differential expression of lncRNA in osteosarcoma tissues and normal tissues was obtained from the GEO database.HEK293 T cells and U2OS and Sao-2 human osteosarcoma cell lines were prepared for culture.The expression of PLK2 in U2OS cell lines was inhibited by siRNA technology and knockdown assay was performed.Total RNA was isolated from U2OS cells for real-time quantitative polymerase chain reaction.Immunoblotting(IB)and immunoprecipitation(IP)analysis were performed on U2OS cell lines,followed by EdU assay and cell viability assay.Finally,SPSS 17.0 version was used for statistical analysis.Cancer tissues were compared with adjacent normal tissues.Results Compared with normal tissues,PLK2 was lower in osteosarcoma tissues.In the experiment of transfecting two kinds of small interfering RNA knocking down PLK2 and recombinant plasmid carrying PLK2 into U2OS cells,it was found that the proliferation ability of U2OS cells was enhanced after PLK2 knockout,while PLK2 overexpression had the opposite effect.The in vivo interaction between PLK2 and p21 was detected in U2OS cells,and it was found that the protein level of p21 was consistent with the protein level of PLK2 and was statistically significant.Conclusion PLK2 is involved in the process of inhibiting the proliferation of osteosarcoma cell,which may occur by interacting with p21.关键词
