RNA-sequencing of inguinal adipose tissue from wild type and adipocyte specific HIF2a knock-out mice upon thermoneutral and cold exposure

Adipose tissue plays an important role in the regulation of wholebody energy homeostasis, depending on external environments. Upon cold acclimation, brown and beige adipocytes dissipate mitochondrial proton gradient generating heat via uncoupling protein 1. Due to increasing demands for oxygen during thermogenesis, adipose tissue could become hypoxic upon cold exposure. Hypoxia-inducible factors (HIFs) are one of the major transcription factors which are involved in various cellular responses under hypoxic condition. Although HIFs regulate diverse metabolic processes with selective target gene expression, their roles in thermogenic adipocytes are still elusive. In this study, we demonstrate that adipocyte HIF2a regulate thermogenic activity upon cold stimuli. To investigate molecular mechanisms of adipocyte HIF2a upon thermoneutral and cold exposure, we report the transcriptomes of inguinal adipose tissue from WT and adipocyte specific HIF2a knock-out mice.
