An Autism-Causing Variant Misregulates Selective Autophagy To Alter Axon Targeting And Behavior, Tyler Buddell
An Autism-Causing Variant Misregulates Selective Autophagy To Alter Axon Targeting And Behavior, Tyler Buddell
Theses and Dissertations
Neurodevelopmental disorders cause debilitating disruptions to the cellular mechanisms that underlie development of the brain. Unfortunately, the complexities of neurodevelopmental disorders make them difficult to study, and the molecular mechanisms perturbed by these disorders remain elusive. Better understanding of neurodevelopmental mechanisms, and the related genes involved, will likely yield new insight into neurodevelopmental disorders. A gene that has been associated with a number of neurodevelopmental disorders is the calcium voltage-gated channel subunit alpha1 C (CACNA1C) gene. Common and rare variants of the CACNA1C gene have been associated with autism and other neurodevelopmental disorders including schizophrenia, bipolar disorder and ADHD. However, …
The Genetics Of Olfactory And Visually Guided Attractive Behaviors In Aedes Aegypti Mosquito, Joshua Ibukun Raji
The Genetics Of Olfactory And Visually Guided Attractive Behaviors In Aedes Aegypti Mosquito, Joshua Ibukun Raji
FIU Electronic Theses and Dissertations
Mosquitoes detect their hosts and seek suitable resources crucial for survival by integrating chemosensory, thermal, and visual cues. The diversity of the cues involved in mosquito attractive behaviors has made the design of behavioral control strategies a challenge. The genetic basis of mosquito attractive behaviors can now be determined using genome editing. The contribution of the IR8a chemosensory pathway was uncovered by disrupting the IR8a co- receptor in Aedes aegypti using CRISPR/Cas9. Ir8a mutant female mosquitoes are not attracted to lactic acid, a behaviorally active component of human sweat, and lack odor-evoked responses to acidic volatiles. The loss of Ir8a …
The Role Of Ash1l During Human Neurodevelopment, Anna Bagnell
The Role Of Ash1l During Human Neurodevelopment, Anna Bagnell
Senior Theses
Autism spectrum disorders (ASD) are associated with defects in neuronal connectivity and are highly heritable. A significant proportion of ASD cases are of complex genetic etiology; complexity which might reflect the impact of gene-environment interactions. However, there is a gap in our understanding of the mechanisms that underlie the gene-environment interaction in autism complex etiology. Genome wide association studies in large ASD cohorts identified high risk variants associated with autism in genes that regulate histone modifications and remodel chromatin. These findings highlight the relevance of chromatin regulatory mechanisms in the pathology of ASD. Changes in Histone H3 methylation have been …
Analysis Of The Genetic And Neurological Components Of Opioid Addiction, With Public Health Perspectives Of The Opioid Epidemic In The United States Of America, Janhavi A. Dubhashi
Analysis Of The Genetic And Neurological Components Of Opioid Addiction, With Public Health Perspectives Of The Opioid Epidemic In The United States Of America, Janhavi A. Dubhashi
DISCOVERY: Georgia State Honors College Undergraduate Research Journal
Opioid addiction has reached epidemic levels around the world, with over-prescription of opioid pain relievers being an often-cited reason for the epidemic in the USA. This project looks at opioid addiction from three perspectives: a review of literature dealing with the neural pathways involved in opioid use and addiction; the underlying genetic differences that can increase the risk of opioid use disorder; and an overview of the public health aspects of the epidemic. The paper will conclude with a review of current and new treatments based upon a growing neurobiological and molecular understanding of opioid use disorder.
Dna Methylation Of The Clusterin Promoter: Associations With Alzheimer’S Disease Risk And Related Phenotypes, Madeline Peretti
Dna Methylation Of The Clusterin Promoter: Associations With Alzheimer’S Disease Risk And Related Phenotypes, Madeline Peretti
Theses: Doctorates and Masters
Background
In 2017 approximately 50 million people worldwide were living with dementia. With Alzheimer’s disease (AD), accounting for 50-70% of dementia cases making this debilitating disease, with no current effective prevention, treatment or cure, a critical healthcare concern. Genome wide association studies (GWAS) have identified a number of risk genes for late onset AD (LOAD); Apolipoprotein E (APOE), a gene involved in the cholesterol/lipid pathway is considered the gene with the greatest risk. The third most associated AD risk gene is Clusterin (CLU), is also involved in the cholesterol/lipid pathway. CLU has been implicated in both …
