A time- and space-resolved nuclear receptor atlas in mouse liver

Abstract

The functional versatility of the liver is paramount for organismal homeostasis. Adult liver functions are controlled by a tightly regulated transcription factor network including nuclear receptors (NRs), which orchestrate many aspects of hepatic physiology. NRs are transcription factors sensitive to extracellular cues such as hormones, lipids, xenobiotics etc. and are modulated by intracellular signaling pathways. While liver functional zonation and adaptability to fluctuating conditions rely on a sophisticated cellular architecture, a comprehensive knowledge of NR functions within liver cell populations is still lacking. As a step toward the accurate mapping of NR functions in liver, we characterized their levels of expression in whole liver from C57Bl6/J male mice as a function of time and diet. Nr1d1 (Rev-erbα), Nr1d2 (Rev-erbβ), Nr1c2 (Pparβ/δ) and Nr1f3 (Rorγ) exhibited a robust cyclical expression in ad libitum-fed mice which was, like most cyclically expressed NRs, reinforced upon time-restricted feeding. In a few instances, cyclical expression was lost or gained as a function of the feeding regimen. NR isoform expression was explored in purified hepatocytes, cholangiocytes, Kupffer cells, hepatic stellate cells and liver sinusoidal cells. The expression of some NR isoforms, such as Nr1h4 (Fxrα) and Nr1b1 (Rarα) isoforms, was markedly restricted to a few cell types. Leveraging liver single cell RNAseq studies yielded a zonation pattern of NRs in hepatocytes, liver sinusoidal cells and stellate cells, establishing a link between NR subtissular localization and liver functional specialization. In summary, we provide here an up-to-date compendium of NR expression in mouse liver in space and time.
