Delayed therapeutic administration of melatonin enhances neuronal survival through AKT and MAPK signaling pathways following focal brain ischemia in mice
Kılıç, Ülkan; Elibol, Birsen; Çağlayan, Ahmet Burak; Beker, Mustafa Çağlar; Beker, Merve; Altuğ Tasa, Burcugül; Uysal, Ömer; Yılmaz, Bayram; Kılıç, Ertuğrul (Springer Nature, 2022)Melatonin has a role in the cell survival signaling pathways as a candidate for secondary stroke prevention. Therefore, in the present study, the coordination of ipsilateral and contralateral hemispheres to evaluate delayed ... -
Expression of Pea3 protein subfamily members in hippocampus and potential regulation following neuronal stimulation
Kandemir, Başak; Davis, Sabrina; Yiğit, Esra Nur; Öztürk, Gürkan; Yılmaz, Bayram; Laroche, Serge; Aksan Kurnaz, Işıl (Elsevier Ireland Ltd, 2020)Pea3 proteins belong to a subfamily of the E-twentysix (ETS) domain superfamily of transcription factors, which play various roles during development. Polyoma Enhancer-Activator 3 (Pea3) proteins Pea3, ERM and Er81 are ... -
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. ... -

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 ... -
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 ... -
Particular phosphorylation of PI3K/Akt on Thr308 via PDK-1 and PTEN mediates melatonin's neuroprotective activity after focal cerebral ischemia in mice
Kılıç, Ülkan; Çağlayan, Ahmet Burak; Beker, Mustafa Çağlar; Günal, Mehmet Yalçın; Çağlayan, Berrak; Yalçın, Esra; Keleştemur, Taha; Gündoğdu, Reyhan Zeynep; Yuluğ, Burak; Yılmaz, Bayram; Kerman, Bilal Ersen; Kılıç, Ertuğrul (Elsevier Sciences Bv, 2017)Apart from its potent antioxidant property, recent studies have revealed that melatonin promotes PI3K/Akt phosphorylation following focal cerebral ischemia (FCI) in mice. However, it is not clear (i) whether increased ...
