Abstract

Breast cancer, as the most common malignancy, is the second leading cause of cancer-related death in women. One of the kelch family member ENC1 is involved in various pathophysiologic processes. But the role of ENC1 in breast cancer has not been investigated. The present study value the feature, clinical significance and the molecular mechanisms of ENC1 in breast cancer. The expression and prognosis value of ENC1 expression among breast cancer and normal breast tissue were investigated in The Cancer Genome Atlas database and human samples. ENC1 was knockdown to explore its function in various breast cancer cell lines. Western blot was performed to explore the potential molecular mechanisms. We observed that ENC1 was overexpressed in breast cancer tissues. ENC1 overexpression was associated with high metastasis and predicted a poor prognosis in patients with breast cancer. ENC1 Knockdown inhibits the growth, clone formation, migration and invasion of breast cancer cells. Mechanism analysis revealed ENC1 was strong associated with the metastasis by modulating β-catenin pathway. Our study emphasizes that ENC1 is a potential prognostic and metastasis-related marker of breast cancer, and may function as a possible therapeutic target against breast cancer.

Keywords: ENC1; breast cancer; metastasis; overexpressed; prognosis; β-catenin pathway.
