Exercise has emerged as a potential modifier of cancer prognosis by influencing tumor biology and patient outcomes. This study used a murine breast cancer model to compare control and voluntary running for 21 days, followed by RNA sequencing, bioinformatics, pan-cancer analysis, and cell experiments. Exercise reduced tumor size and weight, downregulated CD300E at the mRNA level, and altered key pathways including MicroRNAs and calcium signaling. Across cancers, CD300E showed expression variability and upregulation linked to worse prognosis, with roles in proliferation and apoptosis.

Physical activity, particularly exercise, has emerged as a potentially signiﬁcant modiﬁer of cancer prognosis, inﬂuencing tumor biology and patient outcomes. Methods: Using a murine breast cancer model, we established a control and an exercise group, where the latter was subjected to 21 days of voluntary running. RNA Sequencing, bioinformatics analysis, pan-cancer analysis, and cell experiments were performed to validate the underlying mechanisms. Results: We observed that exercise signiﬁcantly reduced tumor size and weight, without notable changes in body weight, suggesting that physical activity can modulate tumor dynamics. mRNA sequencing post-exercise revealed substantial downregulation of CD300E in the exercise group, accompanied by alterations in critical pathways such as MicroRNAs in cancers and the Calcium signaling pathway. Expanding our analysis to a broader cancer spectrum, CD300E demonstrated signiﬁcant expression variability across multiple cancer types, with pronounced upregulation in myeloma, ovarian, lung, and colorectal cancers. This upregulation was correlated with poorer prognostic outcomes, emphasizing CD300E ’s potential role as a prognostic marker and therapeutic target. Moreover, CD300E expression was associated with cancer cell proliferation and apoptosis. Conclusion: The study highlights the dual role of exercise in modulating gene expression relevant to tumor growth and the potential of CD300E as a target in cancer therapeutics. Further research is encouraged to explore the mechanisms by which exercise and CD300E i

FAQs

How did exercise affect tumor growth in the breast cancer model?

Voluntary running for 21 days significantly reduced tumor size and weight without notable changes in body weight, indicating that physical activity modulated tumor dynamics.

What molecular change was observed after exercise?

Post-exercise mRNA sequencing revealed substantial downregulation of CD300E in the exercise group and changes in pathways including MicroRNAs in cancers and the calcium signaling pathway.

What is CD300E’s role across multiple cancer types and outcomes?

CD300E showed significant expression variability across cancer types, with pronounced upregulation in myeloma, ovarian, lung, and colorectal cancers, and this upregulation correlated with poorer prognostic outcomes. CD300E was also associated with cancer cell proliferation and apoptosis.
