Abstract:
Objective To investigate the expressions of SOCS3 and IL‐6 in triple‐negative breast cancer(TNBC)and their clinical significance.Methods The expressions of SOCS3 and IL‐6 in TNBC and normal breast cells were detected by Western blot and fluorescence quantitative PCR.Immunohistochemical staining was used to detect their expressions in 84 TNBCs ,33 breast fibromas and 11 normal breast tissues. The correlation of their expressions in TNBC and the relationship between their expressions and clinical pathological parameters were analyzed as well.Results SOCS3 was not expressed or down‐expressed in TNBC cell lines while IL‐6 was over‐expressed. The positive rate of SOCS3 protein was 32.1% in TNBCs ,63.6% in breast fi‐bromas(P<0.01)and 72.7% in normal breast tissues (P< 0.01);and that of IL‐6 protein was 72.6% in TNBCs ,30.3% in breast fibromas(P< 0.01)and 27.3% in normal breast tissues (P< 0.01).Moreover ,a significant negative correlation was found between the expression of SOCS3 and that of IL‐6 in TNBC(rs = -0.590 ,P<0.01). The expressions of SOCS3 and IL‐6 were markedly associated with tumor size ,lymph node metastasis ,clinical stages and expressions of Ki‐67 and p53(P<0.05) , but not with age ,histological grades or menopausal status(P>0.05).Conclusion The expressions of SOCS3 and IL‐6 are asso‐ciated with the development of TNBC ,suggesting that SOCS3 and IL‐6 can serve as biological markers for evaluating the prog‐nosis ,and therapeutic targets of T NBC.
