Abstract
Colorectal cancer (CRC) is the third most common cancer worldwide and the second leading cause of cancer-related death globally. Also, there is still a lack of effective therapeutic strategies for CRC patients owing to a poor understanding of its pathogenesis. Here, we analysed differentially expressed genes in CRC and identified CPNE7 as a novel driver of colorectal tumorigenesis. CPNE7 is highly expressed in CRC and negatively correlated with patients' prognosis. Upregulation of CPNE7 promotes proliferation and metastasis of cancer cells in vitro and in vivo, and vice versa. Mechanistically, CPNE7 interacts with NONO to initiate ZFP42 transcription, thus promoting CRC progression. Moreover, ZFP42 knockdown inhibits tumor cell proliferation and migration while promoting apoptosis. Notably, delivery of CPNE7 shRNA or the small molecule gramicidin, which blocks the interaction between CPNE7 and NONO, hinders tumor growth in vivo. In conclusion, our findings demonstrate that the CPNE7-NONO-ZFP42 axis promotes colorectal tumorigenesis and may be a new potential therapeutic target.
