Inflammation has been shown to promote obesity-induced insulin resistance. Although pentraxin (PTX) 3 is known as an anti-inflammatory factor, the effect of PTX3 on insulin sensitivity has not yet been elucidated. The aim of this study is to investigate a part of the role of PTX3 on insulin sensitivity. The authors studied the PTX3 and glucose transport protein expression levels in epididymal adipose tissue and soleus muscles of male diabetic-obese [Tsumura Suzuki obese-diabetic (TSOD)] and lean control mice. The levels of PTX3 in both skeletal muscle and adipose tissue were significantly lower in TSOD mice than in controls, and there was a significant positive correlation between them. They observed a significant positive correlation between PTX3 and glucose transport protein 4 levels in skeletal muscle. This study suggests that PTX3 may play a part of role as promoting insulin sensitivity of skeletal muscle in TSOD mice.
