KLF7 induced ADRB3-dependent IL-6 production in brown adipocytes during stress.

ABSTRACT: In recent studies, acute physiological stress has been shown to enhance liver gluconeogenesis by activating β3-adrenergic receptor (ADRB3)-dependent interleukin-6 (IL-6) production in brown adipocytes, effectively fueling "fight or flight" responses. However, the specific molecular mechanism of this IL-6 production in an ADRB3-dependent manner is not fully understood. ADRB3 regulates multiple metabolic programs in adipose tissue, including thermogenesis, lipolysis, and glucose uptake, by activating cAMP-PKA-CREB signaling. Our previous studies revealed that the transcription factor Krüppel-like factor 7 (KLF7) transcriptionally induces IL-6 expression in white adipocytes. Using Klf7-adipocyte knockout mice, we showed that Klf7 is also required for ADRB3-induced IL-6 production during stres
