Abstract

Development of metabolically healthy adipocytes within dysfunctional adipose tissue may represent an attractive way to counteract metabolic syndrome (MetS). In an experimental animal model of high fat diet (HFD)-induced MetS, in vivo, long- and short-term tadalafil treatments were able to reduce visceral adipose tissue (VAT) accumulation and hypertriglyceridemia, and to induce the expression in VAT of the brown fat-specific marker, uncoupling protein 1 (UCP1). VAT preadipocytes (PAD), isolated from the tadalafil-treated HFD rabbits, showed: i) a multilocular morphology; ii) an increased expression of brown fat-specific genes (such as UCP1 and CIDEA); iii) improved mitochondrial structure and dynamic and reduced superoxide production; iv) improved insulin sensitivity. Similar effects were obtained after in vitro tadalafil treatment in HFD rPAD. In conclusion, tadalafil counteracted HFD-associated VAT alterations, by restoring insulin-sensitivity and prompting preadipocytes differentiation towards a metabolically healthy phenotype.
