GDF15 analogs are significantly more effective at inducing weight loss in mice housed at standard room temperature (22°C) compared to thermoneutrality (30°C), with efficacy dropping by half at higher temperatures.
If developing GDF15-based therapies, preclinical data from cold-housed mice may overestimate efficacy compared to thermoneutral conditions. The drug's effectiveness is halved when mice are not cold-stressed.

growth differentiation factor 15 (GDF15) was more effective at 22°C (13% vs. 6%).

More from this paper
- Housing mice at thermoneutrality (30°C) rather than standard room temperature (22°C) does not improve the prediction of human drug efficacy for weight loss, as the direction and magnitude of drug effects vary by mechanism regardless of temperature.Good
- GLP-1 receptor agonists (like semaglutide) and hFGF21 analogs produce similar weight loss efficacy in mice regardless of whether they are housed at standard room temperature (22°C) or thermoneutrality (30°C).Good
- Peptide YY (PYY) analogs show greater weight loss efficacy in mice housed at thermoneutrality (30°C) compared to standard room temperature (22°C), contrary to the trend seen with GDF15.Good
