Chemogenetic inhibition of MCH neurons does not alter memory performance in mice
Mutlu Burnaz, Özlem; Yuluğ, Burak; Öncül, Merve; Çelik, Eşref; Sayar Atasoy, Nilüfer; Çankaya, Şeyda; Hanoğlu, Lütfü; Velioğlu, Halil Aziz (Elsevier Masson s.r.l., 2022)Memory storage in the brain is one of the most extensively studied subjects in neuroscience. However, due to the highly complex structure of the memory-related systems in the brain, the mystery remains unsolved. Consolidation ... -
Impaired melanocortin pathway function in prader-willi syndrome gene-magel2 deficient mice
Öncül, Merve; Dilsiz, Pelin; Ateş Öz, Edanur; Ateş, Tayfun; Aklan, İltan; Çelik, Eşref; Sayar Atasoy, Nilüfer; Atasoy, Deniz (Oxford University Press, 2018)Prader-Willi Syndrome (PWS) is a neurodevelopmental disorder causing social and learning deficits, impaired satiety and severe childhood obesity. Genetic underpinning of PWS involves deletion of a chromosomal region with ... -
Inactivation of Magel2 suppresses oxytocin neurons through synaptic excitation-inhibition imbalance
Ateş, Tayfun; Öncül, Merve; Dilsiz, Pelin; Topçu, İskalen Cansu; Cıvaş, Cihan Civan; Alp, Muhammed İkbal; Aklan, İltan; Öz, Edanur Ateş; Yavuz, Yavuz; Yılmaz, Bayram; Atasoy, Nilüfer Sayar; Atasoy, Deniz (Academic Press Inc Elsevier Science, 2019)Prader-Willi and the related Schaaf-Yang Syndromes (PWS/SYS) are rare neurodevelopmental disorders characterized by overlapping phenotypes of high incidence of autism spectrum disorders (ASD) and neonatal feeding difficulties. ... -
MCH neuron activity ıs sufficient for reward and reinforces feeding
Dilsiz, Pelin; Aklan, İltan; Sayar Atasoy, Nilufer; Yavuz, Yavuz; Filiz, Gizem; Köksalar, Fulya; Ateş, Tayfun; Öncül, Merve; Çoban, İlknur; Ateş Öz, Edanur; Cebecioğlu, Utku; Alp, Muhammed İkbal; Yılmaz, Bayram; Atasoy, Deniz (Karger, 2020)Background: Melanin-concentrating hormone (MCH)-expressing neurons have been implicated in regulation of energy homeostasis and reward, yet the role of their electrical activity in short-term appetite and reward modulation ... -
Neurons from human mesenchymal stem cells display both spontaneous and stimuli responsive activity
Karakaş, Nihal; Bay, Sadık; Türkel, Nezaket; Öztunç, Nurşah; Öncül, Merve; Bilgen, Hülya; Shah, Khalid; Şahin, Fikrettin; Öztürk, Gürkan (Public Library of Science, 2020)Mesenchymal stem cells have the ability to transdifferentiate into neurons and therefore one of the potential adult stem cell source for neuronal tissue regeneration applications and understanding neurodevelopmental ... -
NTS catecholamine neurons mediate hypoglycemic hunger via medial hypothalamic feeding pathways
Aklan, İltan; Sayar Atasoy, Nilufer; Yavuz, Yavuz; Ateş, Tayfun; Çoban, İlknur; Köksalar, Fulya; Filiz, Gizem; Topçu, İskalen Cansu; Öncül, Merve; Dilsiz, Pelin; Cebecioğlu, Utku; Alp, Muhammed İkbal; Yılmaz, Bayram; Davis, Deborah R.; Hajdukiewicz, Karolina; Saito, Kenji; Konopka, Witold; Cui, Huxing; Atasoy, Deniz (Cell Press, 2020)Glucose is the essential energy source for the brain, whose deficit, triggered by energy deprivation or therapeutic agents, can be fatal. Increased appetite is the key behavioral defense against hypoglycemia; however, the ... -
