Preliminary investigation of the gene expression of Tbx3 in human breast carcinoma tissues and the related significance / 解放军医学杂志

ABSTRACT

Objective To explore the role of Tbx3 gene in the occurrence and development of breast cancer. Methods 44 cases of the fresh breast carcinoma tissues and peritumor tissues were collected individually, the gene expression of Tbx3 was detected by RT PCR and the relationship between the changes of Tbx3 gene expression and the related clinicopathological factors of breast carcinoma was investigated. Results Obviously, the expression level of Tbx3 gene in breast carcinoma tissues was higher than that in the peritumor tissues. Furthermore, Tbx3 gene expression level in breast carcinoma tissues was not associated with the tumor size and ages of patients. However, the histological grading of breast carcinoma, tumor infiltrating degree, TNM stagings, and axillary lymph node metastasis were positively correlated with the expression level of Tbx3 gene. Conclusion Tbx3 gene with high expression may promote the occurrence and development of breast cancer and it is also likely a symbol of crucial changes in the development of breast cancer
