Abstract
INTRODUCTION The 24-hour variations in drug absorption, distribution, metabolism, and elimination, collectively known as pharmacokinetics, are fundamentally influenced by rhythmic physiological processes regulated by the molecular clock. Recent advances have elucidated the intricacies of the circadian timing system and the molecular interplay between biological clocks, enzymes and transporters in preclinical level. AREA COVERED Circadian rhythm of the drug metabolizing enzymes and carrier efflux functions possess a major role for drug metabolism and detoxification. The efflux and metabolism function of intestines and liver seems important. The investigations revealed that the ABC and SLC transporter families, along with cytochrome p-450 systems in the intestine, liver, and kidney, play a dominant role in the circadian detoxification of drugs. Additionally, the circadian control of efflux by the blood-brain barrier is also discussed. EXPERT OPINION The influence of the circadian timing system on drug pharmacokinetics significantly impacts the efficacy, adverse effects, and toxicity profiles of various drugs. Moreover, the emergence of sex-related circadian changes in the metabolism and detoxification processes has underscored the importance of considering gender-specific differences in drug tolerability and pharmacology. A better understanding of coupling between central clock and circadian metabolism/transport contributes to the development of more rational drug utilization and the implementation of chronotherapy applications.

Abstract
The main pathological feature of acute lung injury (ALI) is pulmonary edema caused by increased permeability of pulmonary microvascular endothelial cells (PMVECs). LPS was has been confirmed to lead to cell damage and barrier dysfunction in PMVECs. Furthermore, receptor interacting protein 140 (RIP140) was discovered to be increased in LPS-induced human pulmonary microvascular endothelial cells (HPMECs), but the mechanism of RIP140 on LPS-induced HPMECs has not been investigated. In this study, an acute lung injury model was constructed in LPS-induced HPMECs. After RIP140 was downregulated, inflammation, apoptosis and cell permeability levels were detected by RT-qPCR, TUNEL staining and FITC-Dextran, respectively. Western blotting was used to detect the protein levels of related factors. The binding of RIP140 and C-terminal binding protein 2 (CTBP2) was predicted by database and verified by Co-IP. Subsequently, CTBP2 overexpression was transfected into cells and the above experiments were performed again. The results showed that inflammation, apoptosis and permeability levels of LPS-induced HPMECs were remarkably increased compared to the untreated control group. However, these levels were suppressed after RIP140 was silenced compared to the LPS-induced HPMECs group. Notably, the Co-IP study demonstrated that RIP140 and CTBP2 interacted with each other. Moreover, CTBP2 overexpression reversed the inhibitory effects of RIP140 silencing on LPS-induced inflammation, apoptosis and permeability levels in HPMECs. Together, the study found that interference of RIP140 could alleviate LPS-induced inflammation, apoptosis and permeability in HPMECs by regulating CTBP2.

Abstract
The pregnane X receptor (PXR, NR1I2) is a nuclear receptor which exerts its regulatory function by heterodimerization with the retinoid-X-receptor α (RXRα, NR2B1) and binding to the promoter and enhancer regions of diverse target genes. PXR is involved in the regulation of drug metabolism and excretion, metabolic and immunological functions and cancer pathogenesis. PXR activity is strongly regulated by the association with coactivator and corepressor proteins. Coactivator proteins exhibit histone acetyltransferase or histone methyltransferase activity or associate with proteins having one of these activities, thus promoting chromatin decondensation and activation of the gene expression. On the contrary, corepressor proteins promote histone deacetylation and therefore favor chromatin condensation and repression of the gene expression. Several studies pointed to clear cell- and ligand-specific differences in the activation of PXR. In this article, we will review the critical role of coactivator and corepressor proteins as molecular determinants of the specificity of PXR-mediated effects. As already known for other nuclear receptors, understanding the complex mechanism of PXR activation in each cell type and under particular physiological and pathophysiological conditions may lead to the development of selective modulators with therapeutic potential.

Abstract
miR-199a-5p is an important regulator of many biological processes. However, whether and how CYP enzymes are regulated by miR-199a-5p are unknown. Here, we aimed to investigate a potential role of mmu-miR-199a-5p in regulating CYP2 enzymes.Regulatory effects of mmu-miR-199a-5p on CYP expression were assessed in mouse AML-12 hepatocytes. Metabolic activity of CYP2B10 was probed using cyclophosphamide (CPA) as a specific substrate. Regulatory mechanism was investigated using combined luciferase reporter assays and chromatin immunoprecipitation.Of several important drug-metabolizing CYPs, mmu-miR-199a-5p significantly increased the mRNA levels of Cyp2a10, Cyp2c29 and Cyp2j5 in AML-12 cells with Cyp2a10 altered the most. Consistently, mmu-miR-199a-5p enhanced the expression of CYP2B10 protein and cellular metabolism of CPA. Based on database analysis, Cyp2b10 was not a direct target gene of mmu-miR-199a-5p. Thus, a mediator is necessary for the miRNA regulation of CYP2B10. We found that E4BP4 repressed Cyp2b10 transcription and expression through specific binding to a D-box element in the gene promoter. Moreover, mmu-miR-199a-5p inhibited the expression of E4bp4 at the posttranscriptional level by directly targeting the 59-65 nt segment in its 3'UTR.In conclusion, mmu-miR-199a-5p positively regulates CYP2B10 expression through inhibiting its repressor E4BP4. Our findings may provide increased understanding of the complex regulatory pathways for CYP2B10.

Abstract
Beiging is an attractive therapeutic strategy to fight against obesity and its side metabolic complications. The loss of function of the nuclear transcription factor RORα has been related to a lean phenotype with higher thermogenesis in sg/sg mice lacking this protein. Here we show that pharmacological modulation of RORα activity exerts reciprocal and cell-autonomous effect on UCP1 expression ex vivo, in cellulo, and in vivo. The RORα inverse-agonist SR3335 upregulated UCP1 expression in brown and subcutaneous white adipose tissue (scWAT) explants of wild-type (WT) mice, whereas the RORα agonist SR1078 had the opposite effect. We confirmed the reciprocal action of these synthetic RORα ligands on gene expression, mitochondrial mass, and uncoupled oxygen consumption rate in cultured murine and human adipocytes. Time course analysis revealed stepwise variation in gene expression, first of TLE3, an inhibitor of the thermogenic program, followed by a reciprocal effect on PRDM16 and UCP1. Finally, RORα ligands were shown to be useful tools to modulate in vivo UCP1 expression in scWAT with associated changes in this fat depot mass. SR3335 and SR1078 provoked the opposite effects on the WT mice body weight, but without any effect on sg/sg mice. This slimming effect of SR3335 was related to an increased adaptive thermogenesis of the mice, as assessed by the rectal temperature of cold-stressed mice and induction of UCP1 in scWAT, as well as by indirect calorimetry in presence or not of a β3-adrenoceptor agonist. These data confirmed that RORα ligands could be useful tools to modulate thermogenesis and energy homeostasis.NEW & NOTEWORTHY The regulation of adipose tissue browning was not fully deciphered and required further studies explaining how the regulation of this process may be of interest for tackling obesity and related metabolic disorders. Our data confirmed the involvement of the transcription factor RORα in the regulation of nonshivering thermogenesis, and importantly, revealed the possibility to in vivo modulate its activity by synthetic ligands with beneficial consequences on fat mass and body weight of the mice.

Dietary Erythrodiol Modifies Hepatic Transcriptome in Mice in a Sex and Dose-Dependent Way. Int J Mol Sci 2020; 21:ijms21197331. [PMID: 33020388 PMCID: PMC7582860 DOI: 10.3390/ijms21197331] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/04/2020] [Revised: 09/21/2020] [Accepted: 09/29/2020] [Indexed: 01/15/2023] Open
Abstract
Erythrodiol is a terpenic compound found in a large number of plants. To test the hypotheses that its long-term administration may influence hepatic transcriptome and this could be influenced by the presence of APOA1-containing high-density lipoproteins (HDL), Western diets containing 0.01% of erythrodiol (10 mg/kg dose) were provided to Apoe- and Apoa1-deficient mice. Hepatic RNA-sequencing was carried out in male Apoe-deficient mice fed purified Western diets differing in the erythrodiol content. The administration of this compound significantly up- regulated 68 and down-regulated 124 genes at the level of 2-fold change. These genes belonged to detoxification processes, protein metabolism and nucleic acid related metabolites. Gene expression changes of 21 selected transcripts were verified by RT-qPCR. Ccl19-ps2, Cyp2b10, Rbm14-rbm4, Sec61g, Tmem81, Prtn3, Amy2a5, Cyp2b9 and Mup1 showed significant changes by erythrodiol administration. When Cyp2b10, Dmbt1, Cyp2b13, Prtn3 and Cyp2b9 were analyzed in female Apoe-deficient mice, no change was observed. Likewise, no significant variation was observed in Apoa1- or in Apoe-deficient mice receiving doses ranging from 0.5 to 5 mg/kg erythrodiol. Our results give evidence that erythrodiol exerts a hepatic transcriptional role, but this is selective in terms of sex and requires a threshold dose. Furthermore, it requires an APOA1-containing HDL.
