TH receptors (TRs) mediate these hormone effects and are regulated by both hormone families. We reported earlier that THs and oestradiol (E2) determine TR levels in cerebellar cell culture. Here we demonstrate the effects of low concentrations (10-10 M) of the endocrine disruptor (ED) bisphenol A (BPA) on the hormonal (THs, E2) regulation of TRα,β in rat cerebellar cell culture. Primary cerebellar cell cultures, glia-containing and glia-destroyed, were treated with BPA or a combination of BPA and E2 and/or THs. Oestrogen receptor and TH receptor mRNA and protein levels were determined by real-time qPCR and Western blot techniques. The results show that BPA alone decreases, while BPA in combination with THs and/or E2 increases TR mRNA expression. In contrast, BPA alone increased receptor protein expressions, but did not further increase them in combination with THs and/or E2. The modulatory effects of BPA were mediated by the glia; however, the degree of changes also depended on the specific hormone ligand used. The results signify the importance of the regulatory mechanisms interposed between transcription and translation and raise the possibility that BPA could act to influence nuclear hormone receptor levels independently of ligand-receptor interaction.}, year = {2016}, eissn = {1588-2705}, pages = {497-513}, orcid-numbers = {Tóth, István/0000-0002-0168-4753} } @CONFERENCE{MTMT:3016455, title = {Impact of satiety state and testosterone on the metabolic lateralization in the male rat hypothalamus}, url = {https://m2.mtmt.hu/api/publication/3016455}, author = {Tóth, István and Szabó, Csaba and Jócsák, Gergely and Somogyi, Virág and Kiss, Dávid Sándor and Bartha, Tibor and Frenyó V., László and Horváth, Tamás L and Zsarnovszky, Attila}, booktitle = {15th Annual Conference of the Hungarian Neuroscience Society}, unique-id = {3016455}, year = {2015}, orcid-numbers = {Tóth, István/0000-0002-0168-4753} } @CONFERENCE{MTMT:3016451, title = {Ligand-dependent estrogen and thyroid hormone receptor mRNA expression is modulated by the glia}, url = {https://m2.mtmt.hu/api/publication/3016451}, author = {Jócsák, Gergely and Tóth, István and Somogyi, Virág and Kiss, Dávid Sándor and Bartha, Tibor and Frenyó V., László and Horváth, Tamás L and Zsarnovszky, Attila}, booktitle = {15th Annual Conference of the Hungarian Neuroscience Society}, unique-id = {3016451}, year = {2015}, orcid-numbers = {Tóth, István/0000-0002-0168-4753} } @article{MTMT:2986861, title = {Effects of bisphenol-A on cell viability in developing cerebellar cell culture}, url = {https://m2.mtmt.hu/api/publication/2986861}, author = {Jócsák, Gergely and Tóth, István and Somogyi, Virág and Kiss, Dávid Sándor and Bartha, Tibor and Frenyó V., László and Zsarnovszky, Attila}, journal-iso = {ACTA PHYSIOL}, journal = {ACTA PHYSIOLOGICA}, volume = {215}, unique-id = {2986861}, issn = {1748-1708}, year = {2015}, eissn = {1748-1716}, pages = {102-102}, orcid-numbers = {Tóth, István/0000-0002-0168-4753} } @article{MTMT:2986856, title = {Satiety state dependent metabolic sidedness in the hypothalamus of male rats}, url = {https://m2.mtmt.hu/api/publication/2986856}, author = {Tóth, István and Kiss, Dávid Sándor and Jócsák, Gergely and Somogyi, Virág and Bartha, Tibor and Frenyó V., László and Zsarnovszky, Attila}, journal-iso = {ACTA PHYSIOL}, journal = {ACTA PHYSIOLOGICA}, volume = {215}, unique-id = {2986856}, issn = {1748-1708}, year = {2015}, eissn = {1748-1716}, pages = {101-101}, orcid-numbers = {Tóth, István/0000-0002-0168-4753} } @article{MTMT:2940248, title = {Estrogen- and Satiety State-Dependent Metabolic Lateralization in the Hypothalamus of Female Rats.}, url = {https://m2.mtmt.hu/api/publication/2940248}, author = {Tóth, István and Kiss, Dávid Sándor and Jócsák, Gergely and Somogyi, Virág and Toronyi, Éva and Bartha, Tibor and Frenyó V., László and Horváth, Tamás and Zsarnovszky, Attila}, doi = {10.1371/journal.pone.0137462}, journal-iso = {PLOS ONE}, journal = {PLOS ONE}, volume = {10}, unique-id = {2940248}, issn = {1932-6203}, abstract = {Hypothalamus is the highest center and the main crossroad of numerous homeostatic regulatory pathways including reproduction and energy metabolism. Previous reports indicate that some of these functions may be driven by the synchronized but distinct functioning of the left and right hypothalamic sides. However, the nature of interplay between the hemispheres with regard to distinct hypothalamic functions is still unclear. Here we investigated the metabolic asymmetry between the left and right hypothalamic sides of ovariectomized female rats by measuring mitochondrial respiration rates, a parameter that reflects the intensity of cell and tissue metabolism. Ovariectomized (saline injected) and ovariectomized+estrogen injected animals were fed ad libitum or fasted to determine 1) the contribution of estrogen to metabolic asymmetry of hypothalamus; and 2) whether the hypothalamic asymmetry is modulated by the satiety state. Results show that estrogen-priming significantly increased both the proportion of animals with detected hypothalamic lateralization and the degree of metabolic difference between the hypothalamic sides causing a right-sided dominance during state 3 mitochondrial respiration (St3) in ad libitum fed animals. After 24 hours of fasting, lateralization in St3 values was clearly maintained; however, instead of the observed right-sided dominance that was detected in ad libitum fed animals here appeared in form of either right- or left-sidedness. In conclusion, our results revealed estrogen- and satiety state-dependent metabolic differences between the two hypothalamic hemispheres in female rats showing that the hypothalamic hemispheres drive the reproductive and satiety state related functions in an asymmetric manner.}, year = {2015}, eissn = {1932-6203}, orcid-numbers = {Tóth, István/0000-0002-0168-4753; Toronyi, Éva/0000-0002-6284-6373} } @article{MTMT:2822859, title = {Endocrine distruptor effect of Bisphenol A on the developing cerebellum, through estrogen and thyroid hormone receptor expression level changes}, url = {https://m2.mtmt.hu/api/publication/2822859}, author = {Jócsák, Gergely and Somogyi, Virág and Tóth, István and Goszleth, Gréta and Bartha, Tibor and Zsarnovszky, Attila}, journal-iso = {ACTA PHYSIOL}, journal = {ACTA PHYSIOLOGICA}, volume = {211}, unique-id = {2822859}, issn = {1748-1708}, year = {2014}, eissn = {1748-1716}, pages = {127-127}, orcid-numbers = {Tóth, István/0000-0002-0168-4753} } @article{MTMT:2791695, title = {Use of virtual patients in teaching veterinary physiology at the Faculty of Veterinary Science, Szent Istvan University, Budapest}, url = {https://m2.mtmt.hu/api/publication/2791695}, author = {Mándoki, Míra and Jócsák, Gergely and Somogyi, Virág and Kiss, Dávid Sándor and Tóth, István and Bartha, Tibor}, journal-iso = {ACTA PHYSIOL}, journal = {ACTA PHYSIOLOGICA}, volume = {211}, unique-id = {2791695}, issn = {1748-1708}, year = {2014}, eissn = {1748-1716}, pages = {49-49}, orcid-numbers = {Tóth, István/0000-0002-0168-4753} } @article{MTMT:2729311, title = {Metabolic lateralization in the hypothalamus: possible mechanism for cramming multiple functions into a small place}, url = {https://m2.mtmt.hu/api/publication/2729311}, author = {Tóth, István and Kiss, Dávid Sándor and Jócsák, Gergely and Somogyi, Virág and Bartha, Tibor and Frenyó V., László and Zsarnovszky, Attila}, journal-iso = {ACTA PHYSIOL}, journal = {ACTA PHYSIOLOGICA}, volume = {211}, unique-id = {2729311}, issn = {1748-1708}, year = {2014}, eissn = {1748-1716}, pages = {148-148}, orcid-numbers = {Tóth, István/0000-0002-0168-4753} } @CONFERENCE{MTMT:2729285, title = {Metabolic lateralization in the hypothalamus: possible mechanism for cramming multiple functions into a small place}, url = {https://m2.mtmt.hu/api/publication/2729285}, author = {Tóth, István and Kiss, Dávid Sándor and Jócsák, Gergely and Somogyi, Virág and Bartha, Tibor and Frenyó V., László and Zsarnovszky, Attila}, booktitle = {9th FENS Forum of Neuroscience}, unique-id = {2729285}, year = {2014}, orcid-numbers = {Tóth, István/0000-0002-0168-4753} }
