Author contributions: Zhang YX and Zhao L designed the research study; Luan RG, Liu MD and Deng ZF performed the research; Lu CL, Zhang MY, Liu R and Yu ML analyzed the data; Zhao L contributed of pathological tissues; Luan RG wrote the manuscript; An R, Yao YL and Guo DB gave administrative support. All authors have read and approved the final manuscript. Professor Zhang YX and Zhao L jointly designed the experiment. Professor Zhang YX provided most of the experimental platforms and techniques, while Zhao L provided pathological tissues and annotated corresponding general conditions and clinical stages. Subsequent to the initial drafting phase, Professor Zhang YX and Zhao L have contributed equally to the iterative revisions of the manuscript. Following a comprehensive deliberation involving all co-authors, it has been mutually agreed that Professor Zhang YX and Dr. Zhao L be designated as co-corresponding authors.

Core Tip

Core Tip: In this study, we found that SKP1/Cullin1/F-box (SCF)^FBXW7 exhibited a positive correlation with cyclin E1 expression at positions ser73 and thr395 in colon cancer tissues, suggesting that SCF^FBXW7 may facilitate phosphorylation-dependent degradation by interacting with cyclin E1 at these specific sites. Furthermore, the expressions of Cx43 and SCF^FBXW7 were positively correlated, as well as their association with the levels at positions ser73 and thr395. This indicates that Cx43 may enhance the phosphorylation of these two sites through its interaction with SCF^FBXW7, thereby promoting the ubiquitination and degradation of cyclin E1.
