Mice ‘fat’ gene may play role in human obesity

Scientists have identified a gene that appears to control body fat in mice.

Researchers engineered mice without the IRX3 gene, which plays a significant role in regulating body mass and composition.

The mice weighed about 30% less that mice who had the gene.

Another gene, FTO, is thought to have the strongest link to obesity in humans but lead researcher Marcelo Nobrega said the association between FTO and obesity appears to be a result of the influence of the IRX3 gene.
