The Claim

Exposure to hydrogen peroxide and t-butyl hydroperoxide does not induce detectable DNA double-strand breaks or DNA-protein cross-links in HT29 and P31 human cancer cells under the experimental conditions used, suggesting these peroxides primarily cause single-strand DNA damage in this model.

Source: Effects of variation in glutathione peroxidase activity on DNA damage and cell survival in human cells exposed to hydrogen peroxide and t-butyl hydroperoxide.

Description
1 study reviewed
In plain English

In human cancer cells grown in the lab, hydrogen peroxide and t-butyl hydroperoxide do not produce detectable double-strand breaks or DNA-protein cross-links, indicating that the primary type of DNA damage caused by these substances under these conditions is single-strand breaks.

What the research says

1 study
  1. Study: Effects of variation in glutathione peroxidase activity on DNA damage and cell survival in human cells exposed to hydrogen peroxide and t-butyl hydroperoxide.

    The study found that hydrogen peroxide and t-butyl hydroperoxide didn’t break both strands of DNA or stick DNA to proteins in these cancer cells—only single strands got damaged. So yes, the claim is right.
