Yiqi Formula enhance inhibiting effect of cisplatin on triple⁃negative breast cancer by down regulating lncRNA HCP5
Objective: ,To explore the mechanism of Yiqi Formula enhancing the inhibiting function of cisplatin on triple-negative breast cancer.,Methods,2,①The expression levels of lncRNA HCP5 in breast cancer tumor tissues, triple-negative breast cancer tumor and tumor adjacent tissues were compared using TCGA database. ②The expression levels of lncRNA HCP5, PTEN and p-Akt protein in triple-negative breast cancer tumor and tumor adjacent tissues and non-triple-negative breast cancer tumor tissues were detected. ③The xenograft model of nude mice with triple-negative breast cancer was established and treated with cisplatin, Yiqi Formula + cisplatin. Tumor volume, weight and expression levels of lncRNA HCP5, PTEN and P-Akt protein in the tumor were measured.,Results,2,①The data of TCGA showed that the expression level of lncRNA HCP5 in breast cancer tumor tissues was higher than that in tumor adjacent tissues, but the difference was not statistically significant (,P,>,0.05). In Basal-like breast cancer, the expression level of lncRNA HCP5 in tumor tissues was significantly higher than that in tumor adjacent tissues (,P,<,0.01). ②In triple⁃negative breast cancer tumor tissues, the expression level of lncRNA HCP5 was higher than that in tumor adjacent tissues and non-triple-negative breast cancer tumor tissues (,P,<,0.01), the expression level of PTEN protein was lower than that in tumor adjacent tissues and non-triple-negative breast cancer tumor tissues (,P,<,0.001), and the expression level of p-Akt protein was higher than that in tumor adjacent tissues and non-triple-negative breast cancer tumor tissues (,P,<,0.001).③Compared with cisplatin group, the tumor volume and weight of Yiqi Formula + cisplatin group was significantly smaller and lighter (,P,<,0.001), the expression level of lncRNA HCP5 and p-Akt protein decreased(,P,<,0.001), the expression level of PTEN protein increased(,P,<,0.001).,Conclusion,2,Yiqi Formula may increase PTEN protein expression and decrease p-Akt protein expression by down regulating lncRNA HCP5, so as to enhance inhibiting effect of cisplatin on triple-negative breast cancer.
