Breast cancer incidence continues to rise worldwide, and physical exercise is increasingly recognized as a modifier of cancer prognosis by influencing tumor biology and patient outcomes. Using a murine breast cancer model with 21 days of voluntary running, the study applied RNA sequencing, bioinformatics and pan-cancer analyses alongside cellular experiments. Exercise reduced tumor size and weight and increased THSD7B expression, with pathway alterations including microRNAs and calcium signaling. Across cancers, THSD7B varied in expression, was downregulated in multiple tumors, associated with favorable prognosis, and inversely correlated with breast cancer cell proliferation, migration, and invasion.

Physical activity, particularly exercise, has emerged as a sign iﬁcant modiﬁer of cancer prognosis, inﬂuencing both tumor biology and patient outcomes. Methods: In this study, we utilized a murine breast cancer model, dividing mice into a control group and an exercise group; the latter underwent 21 days of voluntary running. We conducted RNA sequencing, bioinformatics analysis, pancancer analysis, and cellular experiments to investigate the underlying mechanisms inﬂuenced by exercise. Results: Exercise led to a signiﬁcant reduction in tumor size and weight. Postexercise mRNA sequencing indicated a notable upregulation of THSD7B in the exercised mice, with signiﬁcant alterations observed in pathways such as MicroRNAs in cancers and the Calcium signaling pathway. In a broader cancer context, THSD7B showed considerable expression variability, being signiﬁcantly downregulated in several cancers, correlating with positive prognostic outcomesin PRAD, LAML, KIRC, and GBM and highlighting its potential role as a prognostic marker and therapeutic target. THSD7B expression was also negatively associated with processes of breast cancer cell proliferation, migration, and invasion. Conclusion: This study underscores the dual role of exercise in modulating gene expression relevant to tumor growth and highlights the potential of THSD7B as a Frontiers in Immunology 01 [frontiersin.org](frontiersin.org) therapeutic targe

FAQs

How was the exercise intervention implemented in the study?

Mice were divided into a control group and an exercise group. The exercise group performed 21 days of voluntary running.

What were the main effects of exercise on tumor outcomes?

Exercise significantly reduced tumor size and tumor weight.

How does THSD7B relate to prognosis and breast cancer cell behavior?

Post-exercise analysis showed notable upregulation of THSD7B. Across cancers, THSD7B expression variability included downregulation in several cancers associated with positive prognostic outcomes, and THSD7B was negatively associated with breast cancer cell proliferation, migration, and invasion.
