Upregulation of inhibitor of DNA binding 1 and 3 is important for efficient thermogenic response in human adipocytes.

ABSTRACT: Brown and beige adipocytes can be activated by β-adrenergic agonist via cAMP-dependent signaling. Performing RNA-sequencing analysis in human cervical area-derived adipocytes, we found that dibutyryl-cAMP, which can mimic in vivo stimulation of browning and thermogenesis, enhanced the expression of browning and batokine genes and upregulated several signaling pathway genes linked to thermogenesis. We observed that the expression of inhibitor of DNA binding and cell differentiation (ID) 1 and particularly ID3 was strongly induced by the adrenergic stimulation. The degradation of ID1 and ID3 elicited by the ID antagonist AGX51 during thermogenic activation prevented the induction of proton leak respiration that reflects thermogenesis and abrogated cAMP analogue-stimulated upregulation of the
