adipose tissue
• ex vivo visceral adipose tissue (VAT) adipocytes isolated from high-fat diet (HFD)-fed mice show a 2.2- to 2.5-fold increase in cytoplasmic mitochondrial DNA (mtDNA)
• however, Rbm43 expression is only mildly (20%) increased
|
• ex vivo VAT adipocytes from HFD-fed mice show a significant decrease in total cellular mtDNA
|
• ex vivo VAT adipocytes from HFD-fed mice contain significantly higher levels of the cGAS product 23-cGAMP as well as increased signaling and gene expression downstream of STING, consistent with cGAS-STING activation
