Thus, further research is required to explicate the latent molecular mechanisms and look for novel biomarkers. E2F3 has been confirmed to be an oncogene in a variety of cancers. However, the particular regulation of E2F3 in colon cancer needs further investigation.  \nMethods: The self-renewal ability was detected through a sphere formation assay. The tumorigenic ability was measured through nude mice in vivo assay. The protein expression of genes was examined through a Western blot. The expression of E2F3 in tumor tissues was detected through an IHC assay. The resistance to cisplatin was assessed through the CCK-8 assay. The cell migration and invasion abilities were measured after upregulating or suppressing E2F3 through the Transwell assay.  \nResults: Results uncovered that E2F3 was upregulated in spheroid cells. In addition, E2F3 facilitates stemness in colon cancer. Moreover, E2F3 facilitated colon cancer cell migration and invasion. Finally, it was revealed that E2F3 affected the STAT3 pathway to modulate stemness in colon cancer. E2F3 served as a promoter regulator in colon cancer, aggravating tumorigenesis and stemness in colon cancer progression through the STAT3 pathway.  \nConclusion: E2F3 may be a useful biomarker for anticancer treatment in colon cancer.  \nKEYWORDS  \nE2F3, stemness, STAT3 pathway, colon cancer, cancer  \nFrontiers in Oncology 01 [frontiersin.org](frontiersin.org)  \nIntroduction  \nColon cancer is one of the most prevalent tumors and results in cancer-interrelated deaths globally (1, 2) . Early surgical operations obviously ameliorate the 5-year survival rate of colon cancer patients, but most advanced colon cancer patients are found to have metastasis and are not suited for surgery (3, 4) . Unluckily, treatment options with useful effects for advanced colon cancer patients were few (5, 6) . Hence, comprehending the relevant molecular regulatory mechanism of colon cancer progression and looking for accurate and serviceable biomarkers were imperative.  \nMore and more factors (lncRNAs, circRNAs, miRNAs, and proteins) as molecular targets have been disclosed to join in the regulation of cancer’s progression, including colon cancer. For example, lncRNA LINC01578 modulates the NF-kB/YY1 axis to strengthen metastasis in colon cancer (7) . CircRNA circCSPP1 combines with miR-431 to regulate ROCK1 and ZEB1, then facilitates the tumorigenesis of colon cancer (8) .
