The aryl hydrocarbon (dioxin) receptor (AhR) has been studied for several decades largely because of its critical role in xenobiotic-induced toxicity and carcinogenesis. Albeit this is a major issue in basic and clinical research, an increasing number of investigators are turning their efforts to try to understand the physiology of the AhR under normal cellular conditions. This is an exciting area that covers cell proliferation and differentiation, endogenous mechanisms of activation, gene regulation, tumor development and cell motility and migration, among others. In this review, we will attempt to summarize the studies supporting the implication of the AhR in those endogenous cellular processes. 相似文献

Mesenchymal stromal cells(MSCs) possess great therapeutic advantages due to their ability to produce a diverse array of trophic/growth factors related to cytoprotection and immunoregulation.MSC activation via specific receptors is a crucial event for these cells to exert their immunosuppressive response.The aryl-hydrocarbon receptor(Ah R) is a sensitive molecule for external signals and it is expressed in MSCs and,upon positive activation,may potentially regulate the MSC-associated immunomodulatory function.Consequently,signalling pathways linked to Ah R activation can elucidate some of the molecular cascades involved in MSC-mediated immunosuppression.In this minireview,we have noted some important findings concerning MSC regulation via Ah R,highlighting that its activation is associated with improvement in migration and immunoregulation,as well as an increase in pro-regenerative potential.Thus,Ah R-mediated MSC activation can contribute to new perspectives on MSC-based therapies,particularly those directed at immune-associated disorders. 相似文献

非酒精性脂肪性肝脏疾病(nonalcoholic fatty liver diseases,NAFLD)是目前备受关注的一种肝脏疾病。肥胖、2型糖尿病、高脂血症等是NAFLD的重要危险因素,但其发病机理仍不十分清楚。芳香烃受体(aryl hydrocarbon receptor,AHR)是由配体激活的转录因子,其在多种重要疾病活动中发挥了重要作用。近年来多项研究表明AHR激活促进了NAFLD的发病进展,对AHR参与NAFLD发病机制的探讨将有利于进一步阐明NAFLD的发病机理,为NAFLD的防治提出新的思路。本文就AHR与NAFLD关系的研究进展做一综述,以期为该领域的研究提供新的方向。 相似文献

2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) and other aryl hydrocarbon receptor (AhR) ligands suppress 17beta-estradiol (E)-induced responses in the rodent uterus and mammary tumors and in human breast cancer cells. Treatment of ZR-75, T47D, and MCF-7 human breast cancer cells with TCDD induces proteasome-dependent degradation of endogenous estrogen receptor alpha (ERalpha). The proteasome inhibitors MG132, PSI, and PSII inhibit the proteasome-dependent effects induced by TCDD, whereas the protease inhibitors EST, calpain inhibitor II, and chloroquine do not affect this response. ERalpha levels in the mouse uterus and breast cancer cells were significantly lower after cotreatment with E plus TCDD than after treatment with E or TCDD alone, and our results indicate that AhR-mediated inhibition of E-induced transactivation is mainly due to limiting levels of ERalpha in cells cotreated with E plus TCDD. TCDD alone or in combination with E increases formation of ubiquitinated forms of ERalpha, and both coimmunoprecipitation and mammalian two-hybrid assays demonstrate that TCDD induces interaction of the AhR with ERalpha in the presence or absence of E. In contrast, E does not induce AhR-ERalpha interactions. Thus, inhibitory AhR-ERalpha cross talk is linked to a novel pathway for degradation of ERalpha in which TCDD initially induces formation of a nuclear AhR complex which coordinately recruits ERalpha and the proteasome complex, resulting in degradation of both receptors. 相似文献
