Paternal Ages And Genetic Diseases And Congenital Anomalies, Neda Hamood
Paternal Ages And Genetic Diseases And Congenital Anomalies, Neda Hamood
The Pegasus Review: UCF Undergraduate Research Journal
he purpose of this research is to investigate the link between Advanced Paternal Ages (APA) (i.e., APA ≥ 35 years and APA ≥ 50 years) and genetic diseases and congenital anomalies. Currently, the relationship between both APA and genetic diseases and congenital anomalies remains unclear. There is room for improvement, however, to investigate systematically the relationship between specific congenital anomalies in newborns and APA. More recently, the link between APA (as opposed to existing studies analyzing Advanced Maternal Age alone) and genetic diseases has been recognized by researchers, epidemiologists, and various health experts. Thus, this study serves to examine the …
Utilizing Markov Chains To Estimate Allele Progression Through Generations, Ronit Gandhi
Utilizing Markov Chains To Estimate Allele Progression Through Generations, Ronit Gandhi
Honors Theses
All populations display patterns in allele frequencies over time. Some alleles cease to exist, while some grow to become the norm. These frequencies can shift or stay constant based on the conditions the population lives in. If in Hardy-Weinberg equilibrium, the allele frequencies stay constant. Most populations, however, have bias from environmental factors, sexual preferences, other organisms, etc. We propose a stochastic Markov chain model to study allele progression across generations. In such a model, the allele frequencies in the next generation depend only on the frequencies in the current one.
We use this model to track a recessive allele …
Incorporating Sex Chromosomes In Transcriptome Prediction Models And Improving Cross-Population Prediction Performance, Daniel S. Araujo
Incorporating Sex Chromosomes In Transcriptome Prediction Models And Improving Cross-Population Prediction Performance, Daniel S. Araujo
Master's Theses
Transcriptome prediction models built with data from European-descent individuals are less accurate when applied to different populations because of differences in linkage disequilibrium patterns and allele frequencies. We hypothesized multivariate adaptive shrinkage may improve cross-population transcriptome prediction, as it leverages effect size estimates across different conditions - in this case, different populations. To test this hypothesis, we made transcriptome prediction models for use in transcriptome-wide association studies (TWAS) using different methods (Elastic Net, Matrix eQTL and Multivariate Adaptive Shrinkage in R (MASHR)) and tested their out-of-sample transcriptome prediction accuracy in population-matched and cross-population scenarios. Additionally, to evaluate model applicability in …
The Effect Of Genetic Relatedness On Mate Selection And Spatial Distribution In The American Alligator, Alligator Mississippiensis, Mark Hoog
Electronic Theses and Dissertations
To date, most genetic studies on the American alligator (Alligator mississippiensis) have focused on population genetics and multiple paternity. There have not been any studies looking at how relatedness affects alligator behavior and movement. This study focused on three main questions: 1) what is the genetic diversity among alligators in this location? 2) can parentage be accurately defined among parents and offspring? and 3) how does individual relatedness affect their spatial distribution? We examined the relatedness of 174 unique individuals from the Okefenokee Swamp Park, in South Georgia, USA. In addition, we placed Telonics® satellite tags on …

Quantitative Song Variety In Relation To Genotype In A Hybridizing Chickadee Population, Shelby Madison Palmer
Quantitative Song Variety In Relation To Genotype In A Hybridizing Chickadee Population, Shelby Madison Palmer
MSU Graduate Theses
The Black-capped chickadee (Poecile atricapillus) and Carolina chickadee (P. carolinensis) are North American songbird species that hybridize in a narrow contact zone stretching latitudinally from New Jersey to Kansas, USA. The association between genetic ancestry and song type in this hybrid zone has been studied independently several times and found to be minimal or absent, likely due to the influence of cultural transmission on learned song in the oscine passerine clade to which the chickadees belong. Despite this, the song of both species remains remarkably distinct in allopatry, suggesting a genetic constraint on certain qualities of …
Alzheimer’S Disease Genetics And Short-Chain Fatty Acid Treatment In Studies Of The Murine Gut Microbiome, Diana Zajac
Alzheimer’S Disease Genetics And Short-Chain Fatty Acid Treatment In Studies Of The Murine Gut Microbiome, Diana Zajac
Theses and Dissertations--Physiology
Elucidating the relationship of the gut microbiome in Alzheimer's Disease (AD) risk and pathogenesis is an area of intense interest. Since 60 to 80% of AD risk is related to genetics and APOE alleles represent the most impactful genetic risk factors for AD, their mechanism(s) of action are under intense scrutiny.
First, I conducted a study on APOE targeted replacement mice to investigate the impact of APOE alleles on the murine gut microbiome. The relative abundance of bacteria from the family Ruminococacceae and related genera increased with APOE2 status. The relative abundance of the class Erysipelotrichia increased with APOE4 status, …
Examining Genetically-Informed Etiologic Models Of Co-Occurring Posttraumatic Stress Disorder And Recreational Cannabis Use Among College Students, Terrell A. Hicks
Examining Genetically-Informed Etiologic Models Of Co-Occurring Posttraumatic Stress Disorder And Recreational Cannabis Use Among College Students, Terrell A. Hicks
Theses and Dissertations
The college years encompass a period of increased risk recreational cannabis use (RCU), as well as a time of increased risk for trauma exposure and developing posttraumatic stress disorder (PTSD). Given the high co-occurrence between RCU and PTSD, and the potentially negative consequences of the two (e.g., worse academic outcomes), there is a need to understand the etiologic mechanisms of these commonly co-occurring conditions. Two primary phenotypic models exist: self-medication model (i.e., PTSD to RCU) and the high-risk model (i.e., RCU to PTSD). To date, there are two existing studies longitudinally examining the etiologic models proposed to explain co-occurring RCU …

Lung-function impairment underlies chronic obstructive pulmonary disease (COPD) and predicts mortality. In the largest multi-ancestry genome-wide association meta-analysis of lung function to date, comprising 580,869 participants, we identified 1,020 independent association signals implicating 559 genes supported by ≥2 criteria from a systematic variant-to-gene mapping framework. These genes were enriched in 29 pathways. Individual variants showed heterogeneity across ancestries, age and smoking groups, and collectively as a genetic risk score showed strong association with COPD across ancestry groups. We undertook phenome-wide association studies for selected associated variants as well as trait and pathway-specific genetic risk scores to infer possible consequences of …
Advancing Methods Of Diet Analysis: A Case Study Using Degraded Merlin (Falco Columbarius) Prey Remains, Taylor A. Coon
Advancing Methods Of Diet Analysis: A Case Study Using Degraded Merlin (Falco Columbarius) Prey Remains, Taylor A. Coon
Undergraduate Theses, Professional Papers, and Capstone Artifacts
Prey remains have long been used as a mechanism to approach diet analyses. As understanding diet is key to comprehending ecosystem dynamics, prey remains identification requires a unique methodological approach to determine diversity within a sample. With the advancement of technology, molecular protocols designed for species-specific identification have improved to incredible accuracy and precision. Yet, the visual identification method has remained a predominant technique within diet studies. With entry-level observers, we matched visual identifications with molecular-based methods to quantify the accuracy of the visual identification method. This study determined what fraction of visually identified prey remains could be correctly identified …
Extension Of The Ergot Alkaloid Gene Cluster, Samantha Joy Fabian
Extension Of The Ergot Alkaloid Gene Cluster, Samantha Joy Fabian
Graduate Theses, Dissertations, and Problem Reports
Specialized metabolites produced by fungi impact human health. A large portion of the pharmaceuticals currently on the market are derived from metabolites biosynthesized by microbes. Ergot alkaloids are a class of fungal metabolites that are important in the interactions of environmental fungi with insects and mammals and also are used in the production of pharmaceuticals. In animals, ergot alkaloids can act as partial agonists or antagonists at receptors for 5-hydroxytryptamine (serotonin), dopamine, and noradrenaline as ergot alkaloids have chemical structures similar to those neurotransmitters. Therefore, they affect insects and mammals that consume them and can be used to produce drugs …
Dfhic: A Dilated Full Convolution Model To Enhance The Resolution Of Hi-C Data, Bin Wang, Kun Liu, Yaohang Li, Jianxin Wang
Dfhic: A Dilated Full Convolution Model To Enhance The Resolution Of Hi-C Data, Bin Wang, Kun Liu, Yaohang Li, Jianxin Wang
Computer Science Faculty Publications
Motivation: Hi-C technology has been the most widely used chromosome conformation capture(3C) experiment that measures the frequency of all paired interactions in the entire genome, which is a powerful tool for studying the 3D structure of the genome. The fineness of the constructed genome structure depends on the resolution of Hi-C data. However, due to the fact that high-resolution Hi-C data require deep sequencing and thus high experimental cost, most available Hi-C data are in low-resolution. Hence, it is essential to enhance the quality of Hi-C data by developing the effective computational methods.
Results: In this work, we propose …
Molecular Genetic Studies Of Horses, Especially With Reference To Aggrecan And Dwarfism, John Edmund Eberth
Molecular Genetic Studies Of Horses, Especially With Reference To Aggrecan And Dwarfism, John Edmund Eberth
Theses and Dissertations--Veterinary Science
This work consists of studies on dwarfism in Miniature horses and a study on breakdowns in Thoroughbreds in relation to gene aggrecan. A correction of the description and designation of D3 dwarf variant in aggrecan (ACAN) from the master’s thesis Chondrodysplasia-like dwarfism in the Miniature horse (2013). Commercial sequencing showed previous sequencing reads presented an artifact and not a single base deletion. Analysis showed a single base missense mutation in exon 8 identified as D3* was the actual cause. Multiple alleles of ACAN associated with chondrodysplastic dwarfism in Miniature horses by Eberth et al. (2018), corrected the …
Dissecting Interactions Across Gene Regulatory Layers In C. Elegans, Morgan Taylor
Dissecting Interactions Across Gene Regulatory Layers In C. Elegans, Morgan Taylor
Biological Sciences Theses and Dissertations
The nematode Caenorhabditis elegans is a powerful tool for studying nervous system genetics. Though relatively simple compared to mammals, C. elegans boasts a remarkably well-conserved neuronal genome and proteome, and its utility in the characterization of neuronal genes has been well-established. However, gene expression is often controlled by complex interactions between multiple genes, and teasing apart the functions of individual genes within such networks remains a challenge. Dissecting these interaction networks is crucial in determining the multifaceted functions of important, conserved regulatory genes. Here we explore interactions between gene regulatory layers in the C. elegans nervous system, employing a synthetic …

A Survey Of Speech-Language Pathologists' Academic Preparation In Craniofacial Anomalies, Francesca Myerski
Honors Theses
Craniofacial anomalies occur in 1 of 750 newborns a year with the three main types being cleft lip, cleft palate, and cleft lip and/or cleft palate. There are six main factors that affect craniofacial anomalies that are focused on in this research, including genetics, environmental factors, medications, diet, health risks, and surgical procedures/surgeons. The research found that there is a lot of information on craniofacial anomalies and speech-language pathologists need to learn about as much as possible. The lack of knowledge and academic preparations speech-language pathologists have in craniofacial anomalies has decreased their awareness in the birth defect and has …

This mosquito species has expanded its geographical range into expanded into the Northern Chihuahuan Desert to further increase the risk of infection by these viruses in naïve human populations. Although Ae. aegypti is abundant along the U.S.â??Mexico border, the biology and ecology of this mosquito species in this temperate/arid climate region is not understood. The objective of this study was to understand the environmental factors that influence the invasive species of Ae. aegypti abundance, breeding habitat selection, host feeding behavior, and …
Ngly1 Deficiency Affects Glycosaminoglycan Biosynthesis And Wnt Signaling Pathway In Mice, Amy Batten
Ngly1 Deficiency Affects Glycosaminoglycan Biosynthesis And Wnt Signaling Pathway In Mice, Amy Batten
PANDION: The Osprey Journal of Research and Ideas
Individuals affected by NGLY1 Deficiency cannot properly deglycosylate and recycle certain proteins. Even though less than 100 people worldwide have been diagnosed with this rare autosomal recessive condition, thousands are affected by similar glycosylation disorders. Common phenotypic manifestations of NGLY1 Deficiency include severe neural and intellectual delay, impaired muscle and liver function, and seizures that may become intractable. Very little is currently known about the various mechanisms through which NGLY1 deficiency affects the body and this has led to a lack of viable treatment options for those afflicted. This experiment uses a loss-of-function (LOF) mouse model of NGLY1 Deficiency homologous …

Skin cancer is one of the most common forms of cancer worldwide. The American Academy of Dermatology estimates that 9500 people in the United States are diagnosed with skin cancer every day, and that 1 in 5 Americans will be diagnosed with skin cancer by age 70. With such a high prevalence of disease, understanding how skin cancer develops and how it can be treated is extremely important. This project aims to analyze the genes involved in the development of the three most common forms of skin cancer: basal cell carcinoma, squamous cell carcinoma, and melanoma.
Regulation And Function Of The Mec-8/Rbpms Rna Binding Protein In Vivo, Xiaoyu Liang
Regulation And Function Of The Mec-8/Rbpms Rna Binding Protein In Vivo, Xiaoyu Liang
Biological Sciences Theses and Dissertations
Alternative splicing is a major form of post-transcriptional regulation of gene expression which plays a pivotal role in cell/tissue- specific identity, diversity, and function. The mechanisms of alternative splicing are well studied; however, the functional consequences of the spliced transcripts are relatively less demonstrated. Therefore, many efforts are needed to understand the physiological relevance of alternative splicing. RNA binding proteins are critical regulators of alternative splicing, their malfunction disrupt the normal networks, and further underlies many diseases. To understand how alternative splicing contributes to the physiological functions in the cells or tissues, we explored the regulatory networks of RNA binding …

A Review On Serum, Genetic And Mirna Associated Biomarkers For The Early Diagnosis Of Hepatocellular Carcinoma (Hcc)), Ambreen Kanwal, Asima Tayyeb
Journal of Bioresource Management
Hepatocellular carcinoma is the most devastating complication of liver cirrhosis and diagnosis in earlier stages could be useful in curative interventions. The main aim of this review was to analyze current diagnostic biomarkers which are available for the early diagnosis of hepatocellular carcinoma (HCC). For this purpose, we searched different web databases including Medline/Pubmed. We found multiple significant serum biomarkers for imperative diagnosis including α- Fetoprotein, Des- γ -carboxyprothrombin (DCP), Osteopontin (OPN), Glypican-3 (GPC3), Golgi protein-73 (GP73), Squamous cell carcinoma antigen (SCCA), Annexin A2 (ANXA2) and Heat shock protein 70 (HSP70) but all of these represent low sensitivity and low …
Investigation Of Neurotransmitter’S Knockdown Effect On Drosophila Melanogaster Female Aggression, Asil N. El Galad
Investigation Of Neurotransmitter’S Knockdown Effect On Drosophila Melanogaster Female Aggression, Asil N. El Galad
Undergraduate Student Research Internships Conference
Drosophila melanogaster (D. melanogaster) is a popular model organism in neurobiology. While aggression has been studied heavily in male drosophila, there's minimal research on aggression in female drosophila. Neurotransmitters influencing aggressive behaviour in female D. melanogaster are poorly understood. Various neurotransmitters such as dopamine, octopamine, and serotonin influence aggression in D. melanogaster Further investigation of the role of neurotransmitters on aggression is thus important. The purpose of our experiment is to observe the effect of the knockdown of dopamine, octopamine and glutamate on aggression in female D. melanogaster.
My Summer Working With Two-Spotted Spider Mites, Renée A. Smith
My Summer Working With Two-Spotted Spider Mites, Renée A. Smith
Undergraduate Student Research Internships Conference
Two-spotted spider mites are a polyphagous pest, capable of eating a magnitude of food crops which causes a large problem for Canadian agriculture. Their ability to consume various crops stems from their ability to adapt to various chemical defence mechanisms. This ability allows them to acquire resistance to many commonly used pesticides. This has resulted in large infections in Canadian farms with few options to prevent the pests from affecting crop yields. Take a look at my project if you'd like to see how the Grbic lab is working to combat this issue using genetic engineering techniques!
Rna-Interference As A Topical Pesticide, Eleanor Khochaba
Rna-Interference As A Topical Pesticide, Eleanor Khochaba
Undergraduate Student Research Internships Conference
Tetranychus urticae are a species of pests that are very problematic in agricultural environments, as they cause lots of damage to a wide variety of crops. One step in figuring out a solution to this problem is through the use of RNA interference. After synchronizing the spider mites, they are treated with the dsRNA solution. The dsRNA is cleavage inside the mite, and the siRNA fragments then bind to a target gene in hopes of homologous sequence recognition leading to knockout/deregulation of the target gene. After treatment, the mites are observed for multiple variables, primarily fecundity and survival. If a …

All HCAS Student Capstones, Theses, and Dissertations
This study provides the first genomics-level, population structure and genetic diversity assessment of the shortfin mako (Isurus oxyrinchus) shark. The assessments were based on mitogenome sequences from makos distributed throughout the Atlantic Ocean, with Pacific mako mitogenomes used as a comparative outgroup. In addition to complete mitogenome-based analyses, I assessed individual mitochondrial coding gene and non-coding (Control Region) sequences for their comparative resolution properties as markers for revealing matrilineal population structure and genetic diversity. Sequencing of 125 makos in the western and eastern Atlantic across northern and southern hemispheres yielded 92 complete mitogenomes (16,698-16,702 bp) and 33 partial …
Description, Diversity, And Phylogeography Of The North American Spider Beetle (Coleoptera: Ptinidae) Genus Coleotestudo, Robert Chambliss
Description, Diversity, And Phylogeography Of The North American Spider Beetle (Coleoptera: Ptinidae) Genus Coleotestudo, Robert Chambliss
Masters Theses & Specialist Projects
A new genus, Coleotestudo, is proposed for the American species currently placed in the genus Niptus LeConte and are transferred herein. Two new species from Mexico are also described as C. potosi n. sp. and C. nahua n. sp. Distinguishing morphological characteristics for the North American Coleotestudo species are given. The combined set of morphological evidence, DNA sequence data, and a Western New World distribution strongly support the hypothesis that Coleotestudo does not share a recent common ancestor with N. hololeucus and both represent unrelated clades of spider beetles.
During the summer of 2021, Coleotestudo was collected mainly from …

The Effects Of Physical Function And Genetics On Cognition And Blood Biomarkers In Individuals At-Risk For Alzheimer’S Disease And Related Dementias, Joshua Louis Gills
Graduate Theses and Dissertations
Alzheimer’s disease and related dementia (ADRD) rates are expected to triple by the year 2050. Early detection and specific mitigation efforts are warranted to blunt the alarming rate. Physical function (PF) declines with age, but higher physical function is associated with better cognitive functioning in middle-to- older age individuals. Moreover, greater physical activity (PA) is associated with better global cognition; however, Apoliporotein e4 carriers may not gain the same benefits with exercise. Additionally, plasma phosphorylated tau 217 (p-tau217) has been identified as a novel diagnostic ADRD biomarker which needs further research to examine associations with risk factors. Therefore, the aims …
