Identifying Rna Splicing Changes During Alcohol Withdrawal Using An Optimized Rna-Seq Analysis Pipeline, Yasaswi Veera, Luana Martins De Carvalho, Amy Lasek
Identifying Rna Splicing Changes During Alcohol Withdrawal Using An Optimized Rna-Seq Analysis Pipeline, Yasaswi Veera, Luana Martins De Carvalho, Amy Lasek

Alcohol use disorder (AUD) causes long-lasting changes in brain gene expression and RNA splicing, particularly in the ventral hippocampus. This study analyzes RNA-Seq data from rats exposed to chronic alcohol and withdrawal to identify transcript-level and splicing alterations. An optimized RNA-Seq pipeline using STAR, FeatureCounts, edgeR, and WGCNA improved efficiency by 25-40% while maintaining consistency across 25 datasets. Results reveal changes in neural signaling and stress-response pathways associated with withdrawal. This work provides both biological insight into AUD and a reproducible computational framework for transcriptomic analysis.
Investigation Of Brain Function And Structural Development As Risk Factors Of Suicidal Thoughts And Behaviors, Yi Zhou
Theses and Dissertations
Background: Identifying risk factors for suicidal thoughts and behaviors, especially causal ones, will be imperative to improving screening and treatment interventions. To identify replicable brain-based risk factors, there is increasing evidence indicating the need for large sample sizes, in the hundreds to thousands, in order to achieve a sufficient level of statistical power to detect them. Furthermore, longitudinal studies of brain and behavioral factors will be essential to understanding how suicide develops, especially the transition from suicide ideation to attempt. While experimental studies may not be feasible or ethical, genetically informed methods for testing evidence for causation are an alternative …

The Role Of Mindfulness In Self-View Investment: Neural And Subjective Indicators, Hadley Rahrig
The Role Of Mindfulness In Self-View Investment: Neural And Subjective Indicators, Hadley Rahrig
Theses and Dissertations
Self-concept is strongly influenced by beliefs about one’s personal psychological attributes, and these beliefs are held with varying degrees of confidence and consequence. Hence, it is investment in self-views of those attributes that helps to regulate and maintain stable self-concept. Self-view investment is relevant to numerous self-related functions, but high self-view investment can also contribute to maladaptive self-views. Theory suggests that mindfulness cultivates a less personal, more objective perception of one’s thoughts, emotions and behaviors, and training in mindfulness has been shown to alter self-referential processing. The current pilot study (N=21) investigates the possible role of dispositional mindfulness in two …
Illumination Of The Golgi Apparatus Of Pathogenic And Nonpathogenic Naegleria Species, Tyler M. Poe
Illumination Of The Golgi Apparatus Of Pathogenic And Nonpathogenic Naegleria Species, Tyler M. Poe
Theses and Dissertations
In this study, Naegleria fowleri, a pathogenic amoeba and the causative agent of Primary Amebic Meningoencephalitis (PAM), was utilized to determine the presence or absence of classically conserved Golgi molecules featured in the expression of a Golgi apparatus. Previous studies concluded no Golgi expression via light microscopy and transmission electron microscopy, but a recent report on Naegleria gruberi indicated the presence of dispersed Golgi tubules. Non-pathogenic species of the Naegleria genus such as Naegleria gruberi 30540 and Naegleria lovaniensis 30569 were utilized in Western immunoblot analysis compared to reduced whole-cell lysate proteins of two strains of N. fowleri and …
Axon Initial Segment Loss Is Not Observed In The Hippocampus Of A Experimental Autoimmune Encephalomyelitis Mouse Model, Praveen Mohanraju
Axon Initial Segment Loss Is Not Observed In The Hippocampus Of A Experimental Autoimmune Encephalomyelitis Mouse Model, Praveen Mohanraju
UROP Posters
The axon initial segment (AIS) is fundamental for neuronal communication and action potential initiation, a characteristic which has been shown to be disrupted in inflammatory diseases such as Multiple Sclerosis (MS). Previous work from our lab has shown AIS breakdown in layer 5 of the cortex in a mouse model of MS known as experimental autoimmune encephalomyelitis (EAE). Moreover, it was shown that AIS breakdown was independent of demyelination but temporally correlated with microglial inflammatory reactivity. In order to determine if this pathology is specific to the cortex or affects other regions of the brain, we exploited these EAE induced …
Allosteric Effects Of G-Protein Coupled Receptor Heteromerization: Relevance To Psychosis, Jason W. Younkin
Allosteric Effects Of G-Protein Coupled Receptor Heteromerization: Relevance To Psychosis, Jason W. Younkin
Theses and Dissertations
G-protein coupled receptors (GPCRs) implicated in disease are the predominant pharmaceutical targets. Growing evidence suggests that GPCRs form homo- and heteromeric complexes, resulting in allosteric functional changes. Ligands targeting one receptor can alter the function of the other receptor or receptors. Knowledge of these functional changes will provide unique opportunities to treat diseases. We examined two GPCR heteromers implicated in psychosis: mGlu2R-5HT2AR and D2R-5HT2AR. Using whole-cell patch clamp, we studied HEK-293 cells stably transfected with mGlu2R and 5HT2AR. Maximal heteromer formation allows inverse agonists to increase the G-protein activity of the opposite receptor, while sub-maximal heteromer formation does not. However, …
Elucidating The Role Of Endogenous Electric Fields In Regulating The Astrocytic Response To Injury In The Mammalian Central Nervous System, Matthew L. Baer
Elucidating The Role Of Endogenous Electric Fields In Regulating The Astrocytic Response To Injury In The Mammalian Central Nervous System, Matthew L. Baer
Theses and Dissertations
Endogenous bioelectric fields guide morphogenesis during embryonic development and regeneration by directly regulating the cellular functions responsible for these phenomena. Although this role has been extensively explored in many peripheral tissues, the ability of electric fields to regulate wound repair and stimulate regeneration in the mammalian central nervous system (CNS) has not been convincingly established. This dissertation explores the role of electric fields in regulating the injury response and controlling the regenerative potential of the mammalian CNS. We place particular emphasis on their influence on astrocytes, as specific differences in their injury-induced behaviors have been associated with differences in the …
