BackgroundBreast cancer is the most commonly diagnosed cancer worldwide. However, the well-known biomarkers are not enough to meet the needs of precision medicine. Novel targets are desirable and highly valuable for improved patient survival. In this regard, we identified complement component C7 as one of the candidates based on data from the OCOMINE database.MethodsC7 expression was examined by immunohistochemistry in 331 cases of invasive ductal carcinoma (IDC), 45 cases of ductal carcinoma in situ (DCIS), and 52 cases of non-neoplastic tissues adjacent to tumor. Then, C7 expression was further confirmed by Western blot analysis based on IDC specimens and non-neoplastic breast specimens. The relationship between the C7 expression and prognosis of breast cancer patients was analyzed in order to investigate the function of C7 in breast cancer patients. Meanwhile, we also analyzed the relationship between the C7 expression and prognosis of 149 patients treated with conventional TE (taxane and anthracycline)-based chemotherapy. Then, a cohort of patients (22 cases) treated with TE neoadjuvant chemotherapy was used to further confirm the relationship between the C7 expression and TE-based chemosensitivity.ResultsIn our present study, we reported for the first time that C7 was an independent prognostic factor of breast cancer and C7 expression of IDC tissues was higher than non-neoplastic tissues adjacent to tumor and DCIS. In a cohort of 331 IDC patients, high expression of C7 indicated poor prognosis especially in the triple negative subtype and luminal B subtype. Furthermore, C7 was also a promoting factor for triple negative subtype patients to develop bone metastasis. Meanwhile, we provided the first evidence that patients with high C7 expression were insensitive to TE (taxane and anthracycline)-based chemotherapy by analyzing a cohort of 149 patients treated with TE-based chemotherapy and another cohort of 22 patients treated with TE neoadjuvant chemotherapy.ConclusionsIn summary, high expression of C7 may promote breast cancer development and might be insensitive to TE-based chemotherapy. Our present study laid a foundation to help clinicians improve the identification of patients for TE-based chemotherapy by C7 in the era of precision medicine.

Background: Breast cancer is a common malignant tumor, threatening the general health of women worldwide. Estrogen-related receptor alpha (ERRα) is a member of nuclear receptor family and has been shown to involve in the pathophysiology of breast cancer. However, the specific relationship between ERRα and the triple negative breast cancer (TNBC), is not clear yet. Objective: This study examined the relevance between ERRα expression and different clinical features of breast cancer patients. Methods: The expression level of ERRα in 150 human breast cancer tissues (which contains 48 human triple negative breast cancer tissues) and 53 human benign breast tumor tissues using immunohistochemical staining. Results: ERRα protein level was significantly higher in breast cancer tissues than that in benign tumors. High expression of ERRα was significantly associated with the high grade but not the clinical stage and human epidermal growth factor receptor 2 of the breast cancer tissues. Its high expression was also positively correlated with triple negative breast cancer in pathological grade 2 and 3, but not in grade 1. high expression of ERRα was positively correlated with triple negative breast cancer in each clinical stage. In addition, high expression of ERRα was associated with shorter overall survival of breast cancer patients. Conclusion: In conclusion, highly expressed ERRα was associated with higher pathological grades triple-negative breast cancer and shorter overall survival. Future studies were required to recruit more patients to consolidate the current findings.
