What this study reported

Measured lower MOTS-c in serum and tumour tissue from patients with ovarian cancer, with lower levels associated with poorer prognosis. In ovarian cancer cells and tumour-bearing mice, exogenous MOTS-c was associated with less proliferation, migration and invasion, with cell cycle arrest and apoptosis, and with LARS1 degradation through competition with USP7.

Limitations

Patient sample sizes are not reported and the clinical association is correlative; animal work uses implanted tumours; the mechanism rests on a single interaction partner.

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.
