Abstract

Non-alcoholic fatty liver disease (NAFLD) is a chronic liver disease. The literature suggests that the aryl hydrocarbon receptor (AHR) may be a key player in the pathogenesis of NAFLD, and it can modulate the synthesis of cytochrome P450 1A1 (CYP1A1) and tumor necrosis factor-α (TNF-α). Previous studies have shown that CYP1A1 is a key enzyme of oxidative stress, TNF-α is involved in the formation of insulin resistance (IR), oxidative stress and insulin resistance are the key factors for the formation of NAFLD. Therefore, it can be said that AHR may participate in contributing to NAFLD by regulating CYP1A1 and TNF-α. Alpha-naphthoflavone (ANF) is an effective AHR inhibitor. The present study was designed to explore the hepatoprotective effect of ANF in high fat diet (HFD)-induced NAFLD mice and oleic acid (OA)-treated HepG2 hepatocytes. Mice were fed HFD to induce NAFLD, HepG2 cells were exposed to OA to induce hepatocyte injury, and ANF significantly reduced mouse and cellular liver damage compared to the HFD-induced NAFLD and OA-treated HepG2 hepatocytes. ANF treatment reduces liver damage by reducing ROS and IR, the data show that ANF inhibits the expression of AHR, CYP1A1 and TNF-α in NAFLD. Taken together, these findings show that ANF alleviate NAFLD via regulation of AHR/CYP1A1 and AHR/TNF-α pathways, which may have potential for further development as novel therapeutic agents for NAFLD.

Abstract

α-Naphthoflavone (αNF) is a prototype flavone, also known as a modulator of aryl hydrocarbon receptor (AhR). In the present study, we investigated the molecular mechanisms of αNF-induced cytotoxic effects in HT22 mouse hippocampal neuronal cells. αNF induced apoptotic cell death via activation of caspase-12 and -3 and increased expression of endoplasmic reticulum (ER) stress-associated proteins, including C/EBP homologous protein (CHOP). Inhibition of ER stress by treatment with the ER stress inhibitor, salubrinal, or by CHOP siRNA transfection reduced αNF-induced cell death. αNF activated mitogen-activated protein kinases (MAPKs), such as p38, JNK, and ERK, and inhibition of MAPKs reduced αNF-induced CHOP expression and cell death. αNF also induced accumulation of reactive oxygen species (ROS) and an antioxidant, N-acetylcysteine, reduced αNF-induced MAPK phosphorylation, CHOP expression, and cell death. Furthermore, αNF activated c-Src kinase, and inhibition of c-Src by a kinase inhibitor, SU6656, or siRNA transfection reduced αNF-induced ROS accumulation, MAPK activation, CHOP expression, and cell death. Inhibition of AhR by an AhR antagonist, CH223191, and siRNA transfection of AhR and AhR nuclear translocator reduced αNF-induced AhR-responsive luciferase activity, CHOP expression, and cell death. Finally, we found that inhibition of c-Src and MAPKs reduced αNF-induced transcriptional activity of AhR. Taken together, these findings suggest that αNF induces apoptosis through ER stress via c-Src-, ROS-, MAPKs-, and AhR-dependent pathways in HT22 cells.

Abstract

Infertility is a global health problem with an estimated incidence of 15%. Exposure to chemicals is a potential causal factor, and there is a lack of studies examining the effects on female germ cells. Here, we have studied the impact of different aryl hydrocarbon receptor (AHR) modulators on human ovarian follicles using a human ovarian tissue culture model. Expression of AHR was analyzed in tissue samples, and effects of the selected ligands resveratrol (RSVL), 6-formylindolo(3,2-b)carbazole (FICZ), and alpha-naphthoflavone (aNF) on AHR transactivation studied in a granulosa cell tumor line. Cortical human ovarian tissue containing preantral follicles was exposed to the ligands or vehicle (dimethylsulfoxide, DMSO) for seven days in vitro. Follicle growth was assessed by counting and measuring follicles from serial tissue sections, cell death quantified using in situ Terminal deoxynucleotidyl transferase dUTP Nick-End Labeling (TUNEL) assay, and steroid hormone production measured using a newly developed ultra-performance liquid chromatography method. AHR was expressed in all donated ovarian tissue samples. FICZ induced AHR transactivation in the granulosa cell line while aNF antagonised it. Compared to DMSO control, FICZ had no effect on follicles in culture, RSVL increased the proportion of growing follicles, and aNF increased cell death, disrupted growth of secondary follicles, increased testosterone, and reduced estradiol levels. We conclude that RSVL supports and aNF disrupts growth of human ovarian follicles in culture. We further conclude that the human ovarian tissue culture model is suitable for studying effects of chemicals on follicular biology.
