Age and gender alter synaptic proteins in zebrafish (Danio Rerio) models of normal and delayed aging
(Bilkent University, 2017-07)Cognitive decline occurs during normal aging in some specific domains of cognitive abilities including but not limited to episodic memory, divided attention and executive functions, however, it is not a unitary decline ... -
Age related alterations of adult neurogenesis and astrocytes in Zebrafish (Danio Rerio)
(Bilkent University, 2019-09)Brain aging is marked by a decline in cognitive abilities and associated with neurodegenerative disorders. In order to identify appropriate interventions to change the course of brain aging and age-related neurological ... -
Age-dependent effects of short-term intermittent fasting and rapamycin treatment in Zebrafish (Danio Rerio) brain
(Bilkent University, 2020-05)World populations are rapidly aging, and there is an urgent need to develop interventions that prevent or reverse age-related deterioration of health. To date, several approaches have been developed to extend health span. ... -
Aging alters the molecular dynamics of synapses in a sexually dimorphic pattern in zebrafish (Danio rerio)
(Elsevier, 2017-06)The zebrafish has become a popular model for studying normal brain aging due to its large fecundity, conserved genome, and available genetic tools; but little data exists about neurobiological age-related alterations. The ... -
Aging, neurogenesis, and caloric restriction in different model organisms
(International Society on Aging and Disease, 2013)Brain aging is a multifactorial process that is occurring across multiple cognitive domains. A significant complaint that occurs in the elderly is a decrement in learning and memory ability. Both rodents and zebrafish ... -
Alterations in the molecular properties of neural stem cells from aged brains and brain tumors
(Bilkent University, 2017-07)It is known that new neuron formation in the brain continues throughout the life of an organism. In the adult human brain, it was proven that neurogenesis in the hippocampus is higher than expected, almost 700 new neurons ... -
The characterization and potential functional role of wdr81, a novel zebrafish gene, associated with cerebellar ataxia, mental retardation and dysequilibrium syndrome (camrq) in humans
(Bilkent University, 2016-04)Cerebellar ataxia, mental retardation and dysequilibrium syndrome (CAMRQ) is a neurodevelopmental disorder. The gene encoding WD repeat containing protein 81 (WDR81) was reported to be associated with CAMRQ2 [MIM 610185]. ... -
Characterization of a novel zebrafish (Danio rerio) gene, wdr81, associated with cerebellar ataxia, mental retardation and dysequilibrium syndrome (CAMRQ)
(BioMed Central Ltd., 2015)Background: WDR81 (WD repeat-containing protein 81) is associated with cerebellar ataxia, mental retardation and disequilibrium syndrome (CAMRQ2, [MIM 610185]). Human and mouse studies suggest that it might be a gene of ... -
Effects of aging and short-term dietary restriction on neurogenesis and cellular senescence in the zebrafish (Danio Reio) brain
(Bilkent University, 2016-09)Currently we know from rodent and fish studies that adult neuron generation is reduced but still continues in old animals with a dynamic change throughout aging. This process occurs mainly in hippocampal region, which is ... -
Expression of key synaptic proteins in Zebrafish (Danio Rerio) brain following caloric restriction and its mimetic and their relationship with gender
(Bilkent University, 2017-01)Aging is a progressive decline of physiological functioning and metabolic processes. Among all the organs, the brain seems to be the most vulnerable part of the body to the age-related changes because of the relatively ... -
Functionally conserved effects of rapamycin exposure on zebrafish
(Spandidos Publications, 2016-03)Mechanistic target of rapamycin (mTOR) is a conserved serine/threonine kinase important in cell proliferation, growth and protein translation. Rapamycin, a well-known anti-cancer agent and immunosuppressant drug, inhibits ... -
Investigating the mechanisms of telomere maintenance in zebrafish tissues and human brain cancer cell lines
(Bilkent University, 2019-09)Telomeres are nucleoprotein complexes formed at each end of the chromosomes to protect these ends from deterioration. In each round of cellular division, telomeric sequences shorten due to the end replication problem of ... -
Nano-formulation for topical treatment of precancerous lesions: Skin penetration, in vitro, and in vivo toxicological evaluation
(Springer Verlag, 2018)With the aim of improving the topical delivery of the antineoplastic drug 5-fluorouracil (5FU), it was loaded into ultradeformable liposomes composed of soy phosphatidylcholine and sodium cholate (UDL-5FU). The liposome ... -
Short-term dietary restriction in old zebrafish changes cell senescence mechanisms
(Elsevier, 2016-10)Brain aging is marked by a decline in cognitive abilities and associated with neurodegenerative disorders. Recent studies have shown, neurogenesis continues into adulthood but is known to be decreasing during advancing age ... -
Tissue specific transcriptome of zebrafish in ache mutant embryos
(Bilkent University, 2019-06)Differential expression of specific genes in certain tissues provides information about tissue specificity which might define phenotypes of various tissues. It is possible to understand the tissue-specific effects of ...
