Systemic PPAR γ deletion in mice provokes lipoatrophy, organomegaly, severe type 2 diabetes and metabolic inflexibility
The peroxisome proliferator-activated receptor γ (PPARγ) is a ligand-dependent transcription factor involved in many aspects of metabolism, immune response and development. Numerous studies relying on tissue-specific invalidation of the Pparg gene have shown distinct facets of its activity, whereas the effects of its systemic inactivation rema in unexplored due to embryonic lethality. By maintaining PPARγ expression in the placenta, we recently generated a mouse model carrying Pparg full body deletion (PpargΔ/Δ), which in contrast to a previously published model is totally deprived of any form of adipose tissue.
