Dr. Paolo SASSONE-CORSI, USA

Epigenetic Mechanism in Clock Function

Symposium – Seasonal Timers and Endocrine Systems

Prof. Takashi YOSHIMURA, Nagoya University, Japan

Mechanisms Underpining Seasonal Reproduction Among Vertebrates

Takashi Yoshimura received PhD from Nagoya University in 1999. He is currently a Professor in the Institute of Transformative Bio-Molecules (WPI-ITbM) and the Graduate School of Bioagricultural Sciences, Nagoya University. He is also a Visiting Professor in the National Institute for Basic Biology, Japan. Dr. Yoshimura works in Yoshimura laboratory focuses on understanding the molecular mechanism of seasonal time measurement in vertebrates. The uniqueness of his research lies in the use of various vertebrate species such as Japanese quail, chicken, hamster, mouse, salmon and medaka. By applying functional genomics approach, he has uncovered the signal transduction pathway regulating seasonal reproduction in vertebrates. He was a board member of the European Biological Rhythms Society and the Society for Research on Biological Rhythms. He currently serves as board member of Japanese Society of Chronobiology and editorial board of Journal of Biological Rhythms, and fellow of Royal Society for Biology.

 Dr. Fran EBLING, University of Nottingham, UK

Tanycytes and Seasonal Timing

Fran Ebling graduated with an Honours degree in Zoology from the University of Bristol, UK, then completed his PhD at the University of Edinburgh under the supervision of Gerald Lincoln investigating the role of melatonin in timing seasonal reproduction in male sheep. He then spent 4 years as a research fellow at the University of Michigan working with Doug Foster on the neuroendocrine control of puberty in female lambs. He returned to the UK to work with Joe Herbert and Michael Hastings on circadian and seasonal rhythms, and then moved to the University of Nottingham where he was appointed to a chair in neuroendocrinology in 2007.  He served as Chair of the British Society for Neuroendocrinology 2006-10.  His research in Nottingham has exploited seasonal cycles in appetite and body weight as a means for understanding the hypothalamic control of energy balance. His Google Scholar H-index is 47 so someone is reading his group’s work, and he remains a lifelong supporter of Sheffield United through the good times and the bad.

Dr. Shona WOOD, University of Manchester, UK

Epigenetics of Seasonal Timing in Pituitary

Shona Wood graduated with an Honours degree in Zoology from the University of Wales, Bangor, UK, and then completed a PhD at the University of Liverpool, UK, in Genomics (2010). She then spent 3 years exploring the relationship between diet and the rate of brain ageing, and demonstrated that nutrition affects the ageing trajectory through changes to the transcriptome and epigenome (University of Liverpool). Her second post-doc was at the University of Manchester, UK, working with Andrew Loudon on the neuroendocrine circuits in the pituitary regulating seasonal timekeeping, and, the role of epigenetics in seasonal timing (2013-2017). This work identified a cellular binary switching mechanism, within the pituitary (pars tuberalis), that defined the phase of the long-term (circannual cycle) in sheep. She has recently moved to the University of Tromsø to take up an independent fellowship position, focusing on the effect of photoperiod and temperature on the trajectory of timed life-history transitions, and, the fundamental biological processes leading to long-term timekeeping, in Arctic mammals.

Dr. Hugues DARDENTE, Physiologie de la Reproduction et des Comportements INRO UMR085, France

Seasonal Rhythms in Sheep Reproduction

Dr. Hugues Dardente is a specialist of biological rhythms, with expertise in neuroendocrinology, molecular biology and cell biology. After being awarded a PhD in Neuroscience form Strasbourg University (France, 2003), Dr. Dardente did two post-doctoral trainings in Montreal (Canada 2003-2006) and Aberdeen (Scotland 2006-2011), working on the molecular underpinnings of circadian rhythms (i.e. clock genes) and the role of melatonin and the pars tuberalis of the pituitary in seasonal rhythms, respectively. Dr. Dardente currently holds a permanent research position at INRA (France) where he keep on working on the molecular and neuroendocrine basis of seasonal and circannual rhythms in sheep.  

Symposium – Biological Timing in Development and Aging

Dr. Carol ELIAS, USA

Enough Energy for Reproduction? It is Time to Grow Up

I received my postdoctoral training at Beth Israel Deaconess Medical Center/Harvard Medical School, Boston-MA in Neurosciences and Neuroendocrinology. Following my postdoctoral training, I returned to Brazil to establish my own independent laboratory, in the Institute of Biomedical Sciences at the University of Sao Paulo, where I worked for about 10 years. In 2006, I went back to the United States (University of Texas Southwestern Medical Center/UTSW, Dallas – TX) for 1-year sabbatical and was invited to join the faculty at the Division of Hypothalamic Research. In 2008, I was appointed Assistant Professor at UTSW, Department of Internal Medicine, in the Division of Hypothalamic Research and was promoted to Associate Professor in 2012. In November of 2012, I was appointed Associate Professor in the Department of Molecular and Integrative Physiology and Department of Obstetrics and Gynecology at the University of Michigan, Ann Arbor. Since January of 2017, I co-direct the Reproductive Sciences Program, from Ob-Gyn Department at the University of Michigan. My main research interest is systems neuroscience and neuroendocrinology, particularly the brain pathways linking metabolism and reproduction. The research in my laboratory aims to determine the neural and molecular mechanisms by which the metabolic imbalance disrupts the reproductive physiology. To accomplish our goals, we use molecular biology tools, mouse genetics and viral vectors for brain mapping, targeted deletion or re-expression of related genes and remote activation or inhibition of neural circuits. Research in my laboratory is funded by the NIH.

Dr. Gil LEVKOWITZ, The Weizmann Institute of Science, Israel 

Cell Fate Decisions in Developing Hypothalamus

Gil Levkowitz received his BSc. and MSc. from Tel Aviv University in Israel. He conducted his Ph.D. research in Prof. Yosef Yarden’s laboratory at the Weizmann Institute of Science focusing on epidermal growth factor receptor (EGFR) signaling, and earned his Ph.D. degree at 2000. He was a Post-Doctoral Fellow (2000-2002) in Arnon Rosenthal’s laboratory at Genentech Inc., (South San Francisco, USA) where he studied the embryonic development of the dopamine- secreting [termed ‘dopaminergic’] neuronal cell type, which is associated with Parkinson’s disease as well as other neurological disorders. He then spent approximately two years (2002-2003) as a project team leader at Rinat-Neuroscience Corp. in Palo Alto. USA (now Rinat-Pfizer Inc.), conducting research and pre-clinical development of drugs for Alzheimer’s and Parkinson’s diseases. Since returning to Israel he has been a Senior Scientist and then an Associate Professor at the Weizmann Institute. His lab is using zebrafish to study genetic pathways controlling the development and function of hypothalamic neuroendocrine and central circuits.
