What this study reported

Measured lower serum MOTS-c after ischemia-reperfusion injury in lung transplantation patients and higher levels when remote ischemic preconditioning preceded transplantation. In mice and endothelial cells, administered MOTS-c was associated with reduced lung injury and preserved endothelial barrier integrity through higher Nrf2 levels, with effects lost in Nrf2 knockout mice and with an Nrf2 inhibitor.

Limitations

Human sample sizes are not reported and the clinical measurements are observational; animal work uses male mice in a single injury model; cell work relies on one endothelial line.

Appraisal

Each dimension is recorded separately and never combined into a single score. A study can be well controlled and still tell you little about people.
