Nuclear factor-erythroid 2-related factor 1 (NFE2L1) is a key transcription factor that regulates cellular adaptive responses to various stresses. Our previous studies revealed that adult adipocyte-specific Nfe2l1-knockout [Nfe2l1(f)-KO] mice show adipocyte hypertrophy and severe adipose inflammation, which can be worsened by rosiglitazone, a peroxisome proliferator-activated receptor γ agonist. To further assess the crucial roles of NFE2L1 in adipocytes, we investigated the effect of CL316243, a β3 adrenergic agonist that promotes lipolysis via a post-translational mechanism, on adipose inflammation in juvenile Nfe2l1(f)-KO mice. In contrast to adult mice, 4-week-old juvenile Nfe2l1(f)-KO mice displayed a normal fat distribution but reduced fasting plasma glycerol levels and elevated adipocyte hypertrophy and macrophage infiltration in inguinal and gonadal WAT. In addition, Nfe2l1(f)-KO mice had decreased expression of multiple lipolytic genes and reduced lipolytic activity in WAT. While 7 days of CL316243 treatment showed no significant effect on adipose inflammation in Nfe2l1-Floxed control mice, the same treatment dramatically alleviated macrophage infiltration and mRNA expression of inflammation and pyroptosis-related genes in WAT of Nfe2l1(f)-KO mice. Together with previous findings in adult mice, the current study highlights that NFE2L1 plays a fundamental regulatory role in lipolytic gene expression and thus might be an important target to improve adipose plasticity and lipid homeostasis.
