ADIPOR2 and hydrops fetalis: However, in the present study, we demonstrated that adipoR1 protein expression increased in muscle and adipoR2 gene expression increased in muscle and liver after 3 weeks of HF diet, suggesting that this may be a compensatory mechanism that acts to protect an organism from insulin resistance induced by HF diet because it has been well documented that adiponectin expression in muscle promotes an increase in insulin sensitivity [52,53].
