Paternal cold exposure enhances brown adipose tissue sensitivity in offspring and ameliorates diet induced obesity
Ontology highlight
ABSTRACT: Research in recent years has focused on environmental effects that control tissue functionality and systemic metabolism. We show here in a retrospective analysis that presence of brown adipocytes and date of birth are correlated and linked to BMI. In a mouse model system, we demonstrate that pre-conception cold exposure leads to improved systemic metabolism and protects from diet induced obesity, through the sperm via the paternal lineage. Using a brown fat ablation model, we show that this effect is mediated by brown adipose tissue. Furthermore, through RNAseq and DNA methylation analysis we identify Adrb3 as a putative signaling mechanism which could mediate the effects of pre-conception cold exposure and could account for the heterogeneity of brown adipose tissue responsiveness. Taken together, our results identify paternal cold exposure as a stimulus which induces a hyper-active state in brown adipose tissue leading to improved adaptation to overnutrition and hypothermia in the offspring.
