Investigation Of Even-Skipped, A Developmentally-Regulated Gene Controlling Neural Segmentation In Dragonflies, Kathryn Bangser
Investigation Of Even-Skipped, A Developmentally-Regulated Gene Controlling Neural Segmentation In Dragonflies, Kathryn Bangser
Honors Theses
A comprehensive understanding of the genetic mechanisms underlying pattern formation and neurogenesis is necessary in order to trace the evolutionary history of insect embryogenesis.
One of the most important processes of embryogenesis is the organized pattern formation that allows for proper body segmentation and neural development. Proper segmentation, which relies on a series of specific gene expressions, is necessary for the development of an operational nervous system. Even-skipped (eve), one such regulatory gene, has been studied extensively in certain model organisms, and theories regarding the evolution of its functional role could be further elucidated by visualizing its expression …
The 5-Ht1a-R Knockout Mouse As A Model Of Later Life Anxiety Disorders: Implications For Sex Differences, Tatyana Budylin
The 5-Ht1a-R Knockout Mouse As A Model Of Later Life Anxiety Disorders: Implications For Sex Differences, Tatyana Budylin
Dissertations, Theses, and Capstone Projects
Anxiety affects nearly twice as many women as it affects men across all cultures and economic groups. Importantly, girls have a higher chance of inheriting anxiety disorders than boys, and many anxiety disorders appear at a very young age. However, little is known about sex differences in brain and behavioral development and how they relate to anxiety in adulthood. Serotonin 1A receptor (5-HT1A-R) mediated signaling has been implicated in depression and anxiety, however most studies that focus on the involvement of the 5-HT1A-R have been conducted in adults. Little is known about how the 5-HT1A …

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 …

A Composite Review Of The Proposed Molecular Mechanisms And Genetic Components Underlying Parkinson’S Disease, Paige Brodrick
Scripps Senior Theses
Parkinson’s disease (PD) is a progressive neurodegenerative disorder characterized by the progressive death of dopaminergic neurons present in the substantia nigra. The clinical presentation of PD includes tremors, slowed movement (bradykinesia), muscle and limb rigidity, and difficulty with walking and balancing. While many environmental factors can affect the onset and progression of the disease, genetic mutations have a large influence. Of the identified PD-linked genetic mutations, mutations in the leucine-rich repeat kinase 2 (LRRK2) are one of the most common genetic causes of PD. Located in endosomes, LRRK2 has been shown to play a role in the sorting and endocytosis …

Alzheimer’s disease is the most common form of dementia in the world with a new case of dementia diagnosed every 3.2 seconds. For over 25 years the amyloid cascade hypothesis has existed as a mechanism of understanding and diagnosing Alzheimer’s Disease. The amyloid cascade hypothesis suggests that Alzheimer’s Disease is sequential in protein progression and proliferative from the medial temporal lobe to the rest of the brain. Hypometabolism of brain regions has also been correlated to plaque deposition and hypometabolism is observed in brain regions that make up the default mode network, specifically the retrosplenial cortex, which is not accounted …
