Molecular Mechanisms of Exercise on Cancer: A Bibliometrics Study and Visualization Analysis via CiteSpace

Objective: To analyze the research hot spots and frontiers of molecular mechanisms of exercise on cancer via CiteSpace.Method: Related publications in the Web of Science Core Collection Science Citation Index Expanded were retrieved from inception to November 27th, 2021. Then we used CiteSpace to generate network maps and identify top authors, institutions, countries, keywords, co-cited authors, journals, references and research trends.Results: A total of 1,130 related publications were retrieved. The most productive author and journal were Lee W Jones and PLOS ONE. Hanahan D and Warburg O were the most cited authors. Fudan University and Shanghai Jiao Tong University were the leading institutions, while China was the leading country. Top-cited authors and references generally focused on the epidemiology and hallmarks of cancer. Top five keywords with both high frequency and high betweenness centrality were breast cancer, aerobic glycolysis, oxidative stress, gene expression, skeletal muscle. Keyword warburg effect ranked first with the highest citation burst, while inflammation, hepatocellular carcinoma, epithelial mesenchymal transition, and adipose tissue were emerging research foci.Conclusion: This study analyzed the research hot spots and frontiers of molecular mechanisms of exercise on cancer via CiteSpace. Based on the results, altered metabolism (aerobic glycolysis, insulin resistance, myokines), oxidative stress, gene expression and apoptosis were hot-research mechanisms of exercise on cancer. Emerging research foci of mechanisms were generally around inflammation, epithelial mesenchymal transition and adipokines. In addition, future studies could carry in-depth research of interactions between different mechanisms and try to elucidate the recommended doses and intensities of exercise for cancer, especially in breast, colorectal, prostate cancer and hepatocellular carcinoma.

Automated summary

This study analyzed the research hot spots and frontiers of molecular mechanisms of exercise on cancer using CiteSpace. The results showed that altered metabolism, oxidative stress, gene expression, and apoptosis were the hot research mechanisms of exercise on cancer, while inflammation, epithelial mesenchymal transition, and adipokines were emerging research foci. Future studies could further explore the interactions between different mechanisms and investigate the recommended doses and intensities of exercise for different types of cancer.
