【 摘 要 】

YEATS domain containing 4 (YEATS4) is usually amplified and functions as an oncogene in human glioma. However, the biological role of YEATS4 in colorectal cancer (CRC) has not yet been discussed. In this study, we investigated the expression level of YEATS4 in 85 pairs of CRC and paracancerous tissues, and knocked down YEATS4 via a lentivirus system in RKO CRC cell line. Although YEATS4 was upregulated in CRC tissues, YEATS4 expression showed no association with any clinical features and overall survival. Inhibition of YEATS4 significantly suppressed cell proliferation and colony formation. Flow cytometry revealed that cell cycle was arrested in the G0/G1 phase and the number of apoptotic cells were significantly increased when YEATS4 expression was inhibited. In conclusion, our findings provide first evidence that YEATS4 may be an important regulator of cell proliferation and apoptosis in CRC cells.
