Genetic deficiency of the lipid droplet protein Fsp27 in mice induces white adipose tissue (WAT) to acquire brown adipose tissue (BAT)-like properties, including increased mitochondrial biogenesis, expression of thermogenic genes (Ucp1, PGC1a), and enhanced energy expenditure, resulting in resistance to diet-induced obesity and improved insulin sensitivity.
This research identifies Fsp27 as a key regulator that prevents white fat from burning energy. While this specific genetic modification is not a current human intervention, it highlights the potential of targeting lipid droplet proteins to enhance metabolic rate and insulin sensitivity. Future therapies might aim to modulate Fsp27 activity to promote 'browning' of white fat, potentially aiding in obesity and diabetes management.
Our data thus suggest that Fsp27 acts as a novel regulator in vivo to control WAT identity, mitochondrial activity and insulin sensitivity.
Why this rating
High-quality mechanistic data in mouse models, but translational relevance to humans is not directly established in this paper.

- Initial treatment for type 2 diabetes should be a combination of metformin and either an SGLT-2 inhibitor or a GLP-1 receptor agonist to achieve cardiorenal protection, rather than monotherapy or older agents like sulfonylureas.Strong
