Abstract:
Objective To detect the protein expression of Cripto-1 and CD34 in basal-like breast carcinoma and study the functions of Cripto-1 in basal-like breast cancer angiogenesis,invasion and metastasis.Methods Immunohistochemistry (IHC) was used to detect the expression of Cripto-1 and CD34 in 60 cases of basal-like breast cancer,40 cases of non basal-like breast cancer and 20 cases of normal breast tissues.The clinical relationship between Cripto-1 and basal-like breast cancer were analyzed as well as its connection with CD34 markers MVD.Results The expression of Cripto-1 protein in basal-like breast cancer (42/60,70.00 ％) was significantly higher than that of nonbasal-like breast cancer (19/40,47.50 ％) and normal breast tissue (4/20,20.00 ％) (both P ＜ 0.05).The expression of Cripto-1 protein was positively correlated with the tumor size,clinical stage,lymph nodes metastasis and MVD value in patients of basal-like breast cancer (all P ＜ 0.05),but there was no corelation with the age of the patients (P ＞ 0.05).Conclusions The up-regulation of Cripto-1 expression may be associated with angiogenesis and development in basal-like breast cancer.The effect of Cripto-1 promoting angiogenesis may be an important factor in the acceleration of the local invasion and distant metastasis in basal-like breast cancer.
