RESUMO
The expression changes of baculovirus inhibitor of apoptosis repeat-containing protein5 in brain glioma after administration of Scutellarin was detected. To explore the effort of scutellarin on anti-glioma by downregulating BIRC5.The effect of scutellarin on tumour growth and animal survival was detected by administering scutellarin to nude mice subcutaneous tumour formation and SD rats in situ tumour formation models. A significantly different gene BIRC5 was found by using the combination of TCGA databases and network pharmacology. And then qPCR was performed to detect the expression of BIRC5 in glioma tissues, cells and normal brain tissues and glial cells. CCK-8 was used to detect the IC50 of scutellarin on glioma cells. The wound healing assay, flow cytometry and MTT test were used to detect the effect of scutellarin on the apoptosis and proliferation of glioma cells. The expression of BIRC5 in glioma tissues was significantly higher than that in normal brain tissues. Scutellarin can significantly reduce tumour growth and improve animal's survival. After scutellarin was administered, the expression of BIRC5 in U251 cells was significantly reduced. And after same time, apoptosis increased and cell proliferation was inhibited. This original research showed that scutellarin can promote the apoptosis of glioma cells and inhibit the proliferation by downregulating the expression of BIRC5.
