Research summary

The study investigates the role of Alms1 in mesenchymal lineage cells. Mesenchymal-specific deletion of Alms1 induces metabolic dysfunction resembling Alström syndrome, including obesity, insulin resistance, and fatty liver. The findings demonstrate that loss of Alms1 in adipose lineage cells is sufficient to drive systemic metabolic alterations and organ dysfunction.

Key outcome of the study

Mesenchymal deletion of Alms1 recapitulates key metabolic features of Alström syndrome including fatty liver and systemic metabolic dysregulation, confirming a central role of adipose lineage dysfunction in disease pathogenesis
