EAR2 is a member of the chick ovalbumin upstream promoter-transcription factors (COUP-TFs). COUP-TFs belong to orphan nuclear receptors and regulate many biological processes. Little is known regarding EAR2 in cancer, though much progress has been made in understanding the function of other COUP-TF members. The aim of this study is to investigate the expression and possible function of EAR2 in colorectal cancer. We determined expression of EAR2 in human primary colorectal malignant tumors and their paired adjacent normal colorectal tissues. We found that expression of EAR2 was upregulated in colorectal tumors. Knockdown of EAR2 induced apoptosis of colon cancer cells, suggesting that EAR2 may function to regulate survivability of colon cancer cells. In vivo tumor study demonstrated that knockdown of EAR2 inhibited the xenograft growth of colon cancer cells. We found that knockdown of EAR2 inhibited the expression of X-linked inhibitor of apoptosis protein (XIAP), suggesting that EAR2 regulates cell survivability, at least partly, through XIAP. In this manuscript, we demonstrated that expression of EAR2 was elevated in colorectal cancer and knockdown of EAR2 reduced survivability and tumor growth of colon cancer cells. Our results suggest that EAR2 plays an important role in development of colorectal cancer. The findings also suggest that EAR2 may serve as a potential therapeutic target of colorectal cancer.
