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, 2017-06)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 ... -
Development of a specialized zebrafish xenotransplantation database and establishment of ALU-based tumor DNA quantification method in zebrafish: focus on models of overexpression and microenvironment
(Bilkent University, 2020-09)Successful xenotransplantation of human cancer cells into zebrafish host marked a new era in cancer research enabling high throughput in vivo screens. Zebrafish xenotransplantation literature continues to rapidly accumulate, ... -
Dietary and pharmacological interventions that inhibit mammalian target of rapamycin activity alter the brain expression levels of neurogenic and glial markers in an age-and treatment-dependent manner
(Mary Ann Liebert, 2020)Intermittent fasting (IF) and its mimetic, rapamycin extend lifespan and healthspan through mechanisms that are not fully understood. We investigated different short-term durations of IF and rapamycin on cellular and ... -
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 ... -
Effects of aging, diet and potential genetic interventions on the levels of Smurf2 and its interacting partners in Zebrafish (Danio Rerio) brain
(Bilkent University, 2020-09)Aging is a natural process that is ultimate combination of numerous intrinsic and extrinsic changes in an organism. Contrary the common belief, brain aging is not a loss of neurons while it has been shown that subtle ... -
Expression levels of SMAD specific E3 ubiquitin protein ligase 2 (Smurf2) and its interacting partners show region-specific alterations during brain aging
(Elsevier, 2020)Aging occurs due to a combination of several factors, such as telomere attrition, cellular senescence, and stem cell exhaustion. The telomere attrition-dependent cellular senescence is regulated by increased levels of SMAD ... -
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 ... -
Genetic and environmental interventions altering the course of brain aging: evidence from the zebrafish (Danio Rerio) model
(Bilkent University, 2021-04)Age-related cognitive decline occurs during normal aging, although there is no prominent neural loss in the brain. Subtle molecular alterations in synaptic and cellular dynamics are likely underlying these cognitive ... -
Investigating motion detection of aging zebrafish with optomotor response
(Bilkent University, 2021-07)Various aspects of visual functioning including motion perception have been shown to be significantly altered throughout aging. Contrary to the traditional view focusing on structural changes in the eye and retina, ... -
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 ... -
Modulation of the neuroinflammatory response following genetic and environmental manipulations in the zebrafish (Danio Rerio)
(Bilkent University, 2022-05)Aging is an inevitable process through which organisms experience functional and physical decline. Cellular changes such as mitochondrial dysfunction, telomere attrition, and loss of proteostasis constitute the main ... -
