The content of this article has been presented as an initial exploratory study and the clinical importance of this study has not been overstated. The article outlines the reasons that studying organisms from geographical isolated locations such as the Antartic could be important for drug discovery in cancer. The article seeks the opinion on the researcher involved in the study, however it would have been good to also seek expert opinion from an independent expert in the field. It would have also been good to have further details about the studies that have tested the isolated bacterium compound on melanoma or other cancer cell lines and a link to these at the end of the article.

Overall, this press article has provided a reasonable amount of context to the study findings. The press article has both insights from the lead author on the study and also expert commentary from a public health researcher who did not contribute to the study, which provides good balance. Perhaps the article could have emphasised that the study evidence was predominantly from in vivo/biomarkers and that epidemiological evidence is still lacking, although this is mentioned in the article. The research study is also linked so that readers can easily view the original study which is great.

While the results of this research are interesting, the title of the media summary 'Short bouts of exercise can protect against bowel cancer, according to a study, giving researchers hopes for new cancer treatments' is slightly overstated given the evidence presented in the paper.

The media summary of this research is clear, however, it is also very brief and therefore lacks some context. In the study, a colon cancer cell line was used as a model system to examine the effect of exposure to pre- and post-exercise blood serum samples on RNA expression and nuclear γ-H2AX was quantified to assess DNA damage repair. The article could highlight that in vitro findings provide only a potential mechanism, and further investigation would be required to determine whether the similar effects of exercise exposure are also seen in tumour tissue or in vivo model systems.

The original research article was not linked in the media summary, linking the paper would make it easier for readers to view the evidence presented in the paper.
