In both teleosts and mammals, melatonin produced in the pineal gland at night is released into the blood and cerebrospinal fluid, providing rhythmic information to the whole organism. Melatonin acts\ via\ specific receptors, allowing the synchronization of daily and annual physiological rhythms to environmental conditions. The pituitary gland, which produces several hormones involved in a variety of physiological processes such as growth, metabolism, stress and reproduction, is an important target of melatonin. Melatonin modulates pituitary cellular activities, adjusting the synthesis and release of the different pituitary hormones to the functional demands, which changes during the day, seasons and life stages. It is, however, not always clear whether melatonin acts directly or indirectly on the pituitary. Indeed, melatonin also acts both upstream, on brain centers that control the pituitary hormone production and release, as well as downstream, on the tissues targeted by the pituitary hormones, which provide positive and negative feedback to the pituitary gland. In this review, we describe the known pathways through which melatonin modulates anterior pituitary hormonal production, distinguishing indirect effects mediated by brain centers from direct effects on the anterior pituitary. We also highlight similarities and differences between teleosts and mammals, drawing attention to knowledge gaps, and suggesting aims for future research.}, doi = {10.3389/fendo.2020.605111}, url = {https://www.frontiersin.org/articles/10.3389/fendo.2020.605111/full}, author = {Ciani, Elia and Haug, Trude M. and Maugars, Gersende and Weltzien, Finn-Arne and Falc{\'o}n, Jack and Fontaine, Romain} } @article {6018, title = {Functional divergence of thyrotropin beta-subunit paralogs gives new insights into salmon smoltification metamorphosis}, journal = {Scientific Reports}, volume = {9}, year = {2019}, pages = {4561}, author = {Fleming, Mitchell S and Maugars, Gersende and Lafont, Anne-Gaelle and Rancon, Jocelyn and Fontaine, Romain and Nourizadeh-Lillabadi, Rasoul and Weltzien, Finn-Arne and Santidrian Yebra-Pimentel, Elena and Dirks, Ron and McCormick, Stephen D and Rousseau, Karine and Martin, Patrick and Sylvie Dufour} } @article {4756, title = {Nuclear and membrane progestin receptors in the European eel: characterization and expression in vivo through spermatogenesis}, journal = {Comparative Biochemistry and Physiology, Part A}, volume = {207}, year = {2017}, pages = {79-92}, author = {Morini, Marina and Penaranda, David S and V{\'\i}lchez, M C and Nourizadeh-Lillabadi, R and Anne-Gaelle Lafont and Sylvie Dufour and Asturiano, J F and Weltzien, Finn-Arne and Perez, Luz} } @article {5016, title = {Rapid de novo assembly of the European eel genome from nanopore sequencing reads}, journal = {Scientific Reports}, volume = {7}, year = {2017}, pages = {7213}, author = {J.
