摘要：
PUS7 is identified as a crucial regulator of pseudouridylation of 7SK RNA, which plays a significant role in transcription elongation in colorectal cancer (CRC) cells. The study demonstrates that depletion of PUS7 enhances the sensitivity of CRC cells to 5-fluorouracil (5-FU) chemotherapy by promoting the expression of apoptosis-related genes KLF6 and DDIT3. This research underscores the potential of targeting PUS7 in cancer therapies, particularly for enhancing the efficacy of existing treatments.
