Investigating FNDC4's function in colon cancer and its molecular mechanism is the goal of this study. The expression of FNDC4 and M2 macrophage-related genes (CD163 and CD206) in tumor tissues was found using immunohistochemistry. After transfecting colorectal cancer cells with the FNDC4 knockdown plasmid, CCK8, clone formation, scratch assay, and Transwell test were used to determine cell proliferation, migration, and invasion. Using flow cytometry, the amount of CD163, CD206, and the rate of cell death were found. Western blot was utilized to identify the expression of proteins associated with the Akt/STAT3 pathway, M2 macrophages, and epithelial-mesenchymal cells. To see how sh-FNDC4 affected tumor growth, a xenograft tumor model was created, and H&E staining was used to look at liver tissue metastases. The findings demonstrated that FNDC4 was favorably connected with the expression of CD206 and CD163 and that it was substantially expressed in colorectal cancer. Tumor cell proliferation, migration, invasion, EMT, and M2 macrophage polarization were all reduced by FNDC4 knockdown. Furthermore, FNDC4 knockdown suppressed tumor growth and liver metastasis in vivo by blocking the Akt/STAT3 pathway. In conclusion, FNDC4's modulation of the Akt/STAT3 pathway may be the reason why its knockdown prevented colorectal cancer cell proliferation, metastasis, and M2 macrophage polarization.</div></div>","PeriodicalId":18707,"journal":{"name":"Molecular and Cellular Endocrinology","volume":"615 ","pages":"Article 112738"},"PeriodicalIF":3.6,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146092771","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Implementation of these small molecules in advanced testing systems not necessarily used in screening, which identified lead compounds, has yielded a bounty of wonders. It is likely that a richer understanding of the role of signaling platforms and conformation-dependent molecular assemblies are likely to emerge. Several small molecule agonists have been observed to function as conformational boosters that can rescue receptor trafficking defects, or initiate internalization of receptors without bound hormone. Still others have revealed insights into the role of molecular platforms in persistent signaling. Unexpectedly, such antagonists, like molecular scalpels, can ablate certain signaling pathways and not others leading to discovery of biased signaling in gonadotropin receptors. That seminal observation has led to studies of nuanced signaling and, consequently, nuanced gene expression. Gonadotropin receptor structure-based design for better specificity and potency of agonists and antagonists has been provided by new cryo-EM structures of the gonadotropin receptors, demonstrating proof of concept.
