Abstract
Caspase recruitment domain family, member 14 (CARD14) is a member of the CARD family of proteins, which play an important role in immune and inflammatory response, and cell survival and proliferation. Here, we identified the role of CARD14 in human breast cancer. Immunohistochemistry was performed to evaluate CARD14 expression in breast cancer. Using CARD14 knockdown cells by small interfering RNA, colony formation and MTT assays, flow cytometry analyses, and migration assays were performed to evaluate the proliferation, cell cycle distribution, apoptosis, and migration ability of MCF7 and SK-BR-3 cells. CARD14 expression was significantly higher in breast cancer samples than in normal breast samples. CARD14 knockdown inhibited cell proliferation and migration, caused cell cycle arrest at the G1/S boundary, and promoted apoptosis. CARD14 regulates the proliferation and migration of MCF7 and SK-BR-3 cells; it is thus, a novel potential therapeutic target in breast cancer.
