Abstract
Metabolic diseases are a series of metabolic disorders that include obesity, diabetes, insulin resistance, hypertension, and hyperlipidemia. The increased prevalence of metabolic diseases has resulted in higher mortality and mobility rates over the past decades, and this has led to extensive research focusing on the underlying mechanisms. Xenobiotic receptors (XRs) are a series of xenobiotic-sensing nuclear receptors that regulate their downstream target genes expression, thus defending the body from xenobiotic and endotoxin attacks. XR activation is associated with the development of a number of metabolic diseases such as obesity, nonalcoholic fatty liver disease, type 2 diabetes, and cardiovascular diseases, thus suggesting an important role for XRs in modulating metabolic diseases. However, the regulatory mechanism of XRs in the context of metabolic disorders under different nutrient conditions is complex and remains controversial. This review summarizes the effects of XRs on different metabolic components (cholesterol, lipids, glucose, and bile acids) in different tissues during metabolic diseases. As chronic inflammation plays a critical role in the initiation and progression of metabolic diseases, we also discuss the impact of XRs on inflammation to comprehensively recognize the role of XRs in metabolic diseases. This will provide new ideas for treating metabolic diseases by targeting XRs. SIGNIFICANCE STATEMENT: This review outlines the current understanding of xenobiotic receptors on nutrient metabolism and inflammation during metabolic diseases. This work also highlights the gaps in this field, which can be used to direct the future investigations on metabolic diseases treatment by targeting xenobiotic receptors.

Fang M, Zhang Q, Yu P, Ge C, Guo J, Zhang Y, Wang H. The effects, underlying mechanism and interactions of dexamethasone exposure during pregnancy on maternal bile acid metabolism. Toxicol Lett 2020; 332:97-106. [PMID: 32599024 DOI: 10.1016/j.toxlet.2020.06.011] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/07/2020] [Revised: 06/07/2020] [Accepted: 06/16/2020] [Indexed: 12/12/2022]
Abstract
As important members in steroids related signal pathways, bile acids are very important in regulating substance metabolism and immune homeostasis. However, bile acids are highly cytotoxic, and the excessive accumulation can induce several abnormalities such as cholestatic liver injury. It is known that the bile acid metabolism alters during pregnancy and mostly will not result in pathologies. However, the effect of dexamethasone exposure during pregnancy on bile acid metabolism is still unknown. In this study, pregnant Wistar rats were subcutaneously administered dexamethasone (0.2 mg/kg.d) or saline from gestation day 9-21, while virgin rats were given the same treatment for 13 days. We found that, physiological pregnancy or dexamethasone exposure during non-pregnancy did not affect maternal serum TBA level and liver function. Nevertheless, dexamethasone exposure during pregnancy increased serum TBA level and accompanied with liver injury. Furthermore, we discovered that the conservation of bile acid homeostasis under pregnancy or dexamethasone exposure was maintained through compensatory pathways. However, dexamethasone exposure during pregnancy tipped the balance of liver bile acid homeostasis by increasing classical synthesis and decreasing efflux and uptake. In addition, dexamethasone exposure during pregnancy also increased serum estrogen level and nuclear receptors mRNA expression levels. Finally, two-way ANOVA analysis showed that dexamethasone exposure during pregnancy could induce or facilitate maternal cholestasis and liver injury by up-regulating ERα and CYP7A1 expression. This study confirmed that dexamethasone exposure during pregnancy was related to maternal intrahepatic cholestasis of pregnancy and should be carefully monitored in clinical settings.

Dexamethasone-Induced Liver Enlargement Is Related to PXR/YAP Activation and Lipid Accumulation but Not Hepatocyte Proliferation. Drug Metab Dispos 2020; 48:830-839.

Abstract
Dexamethasone (Dex), a widely prescribed anti-inflammatory drug, was reported to induce liver enlargement (hepatomegaly) in clinical practice and in animal models. However, the underlying mechanisms are not elucidated. Dex is a known activator of pregnane X receptor (PXR). Yes-associated protein (YAP) has been implicated in chemically induced liver enlargement. Here, the roles of PXR and YAP pathways were investigated in Dex-induced hepatomegaly. Upregulation of PXR downstream proteins, including cytochrome P450 (CYP) 3A11, 2B10, and organic anion transporter polypeptide 2 (OATP2), indicated PXR signaling was activated after high dose of Dex (50 mg/kg, i.p.), and Dex at 100 μM activated PXR in the dual-luciferase reporter gene assay. Dex also increased the expression of total YAP, nuclear YAP, and YAP downstream proteins, including connective tissue growth factor and cysteine-rich angiogenic inducer 61, indicating activation of the YAP pathway. Furthermore, nuclear translocation of YAP was promoted by activation of PXR. However, hepatocyte proliferation was inhibited with significant decrease in the expression of proliferation-related proteins cyclin D1 and proliferating cell nuclear antigen as well as other regulatory factors, such as forkhead box protein M1, c-MYC, and epidermal growth factor receptor. The inhibitory effect of Dex on hepatocyte proliferation was likely due to its anti-inflammation effect of suppression of inflammation factors. β-catenin staining revealed enlarged hepatocytes, which were mostly attributable to the accumulation of lipids, such as triglycerides. In summary, high-dose Dex increased liver size accompanied by enlarged hepatocytes, and this was due to the activation of PXR/YAP and their effects on lipid accumulation but not hepatocyte proliferation. These findings provide new insights for understanding the mechanism of Dex-induced hepatomegaly. SIGNIFICANCE STATEMENT: This study identified the roles of pregnane X receptor (PXR) and yes-associated protein (YAP) pathways in dexamethasone (Dex)-induced hepatomegaly. Dex induced PXR/YAP activation, enlarged hepatocytes, and promoted liver enlargement with lipid accumulation, such as triglycerides. However, hepatocyte proliferation was inhibited by the anti-inflammatory effect of Dex. These findings provide new insights for understanding the mechanism of Dex-induced hepatomegaly.
