Circadian Rhythmicity And Neurodevelopment Of Disco And Grim Mutations In Drosophila Melanogaster, John Patrick Story Apr 2019

Circadian Rhythmicity And Neurodevelopment Of Disco And Grim Mutations In Drosophila Melanogaster, John Patrick Story

EURēCA: Exhibition of Undergraduate Research and Creative Achievement

The death gene grim and its pathway for apoptosis has been studied extensively in Drosophila Melanogaster. The effects of grim mutations on circadian neurodevelopment and locomotor assays have yet to be investigated. Mutations in the gene disconnected (disco) has been shown to disrupt the normal development of the circadian circuitry, specifically the small ventro-lateral neurons (s-LNv’s). Which has shown to severely decrease rhythmicity during free-running periods. Alternatively, we have observed an increase in rhythmicity during free-running periods in grim mutations. Our goal is to investigate the neurodevelopment of the circadian circuitry and their associated locomotor activities in these Drosophila ...


A Polymorphism In The Fatty Acid Desaturase-2 Gene Is Associated With The Arachidonic Acid Metabolism In Pigs, Sofia Gol, Ramona N. Pena, Max F. Rothschild, Marc Tor, Joan Estany Apr 2019

A Polymorphism In The Fatty Acid Desaturase-2 Gene Is Associated With The Arachidonic Acid Metabolism In Pigs, Sofia Gol, Ramona N. Pena, Max F. Rothschild, Marc Tor, Joan Estany

Max Rothschild

Arachidonic acid (C20:4) is related to a wide range of biological effects including lipid homeostasis. The fatty acid desaturase-2 (FADS2) gene encodes for the delta-6-desaturase, which is involved in the biosynthesis of C20:4 from linoleic acid (C18:2). The purpose of this study was to characterise mutations in the promoter of the porcine FADS2, evaluating in particular the effect of one haplotype tagging polymorphism (rs321384923A > G) on the biosynthesis pathway of C20:4. A total of 1,192 Duroc barrows with records on fatty acid composition in muscle and subcutaneous fat were genotyped. Pigs carrying the A allele ...

Background: Goat populations that are characterized within the AdaptMap project cover a large part of the worldwide distribution of this species and provide the opportunity to assess their diversity at a global scale. We analysed genome-wide 50 K single nucleotide polymorphism (SNP) data from 144 populations to describe the global patterns of molecular variation, compare them to those observed in other livestock species, and identify the drivers that led to the current distribution of goats.

Results: A high degree of genetic variability exists among the goat populations studied. Our results highlight a strong partitioning of molecular diversity between and within ...


Genome-Wide Association Studies Of Inflammatory Bowel Disease In German Shepherd Dogs, Atiyeh Peiravan, Francesca Bertolini, Max Rothschild, Kenneth W. Simpson, Albert E. Jergens, Karin Allenspach, Dirk Werling Apr 2019

Genome-Wide Association Studies Of Inflammatory Bowel Disease In German Shepherd Dogs, Atiyeh Peiravan, Francesca Bertolini, Max Rothschild, Kenneth W. Simpson, Albert E. Jergens, Karin Allenspach, Dirk Werling

Max Rothschild

Canine Inflammatory Bowel Disease (IBD) is considered a multifactorial disease caused by complex interactions between the intestinal immune system, intestinal microbiota and environmental factors in genetically susceptible individuals. Although IBD can affect any breed, German shepherd dogs (GSD) in the UK are at increased risk of developing the disease. Based on previous evidence, the aim of the present study was to identify single nucleotide polymorphisms (SNPs), which may confer genetic susceptibility or resistance to IBD using a genome-wide association study (GWAS). Genomic DNA was extracted from EDTA blood or saliva samples of 96 cases and 98 controls. Genotyping of cases ...


A Screen For Genetic Modifiers Of Protein Phosphatase 1 Function In Drosophila Collective Cell Cohesion And Migration, Carmen F. Del Real, Yujun Chen, Marissa Komp, Jocelyn A. Mcdonald Apr 2019

A Screen For Genetic Modifiers Of Protein Phosphatase 1 Function In Drosophila Collective Cell Cohesion And Migration, Carmen F. Del Real, Yujun Chen, Marissa Komp, Jocelyn A. Mcdonald

Kansas State University Undergraduate Research Conference

Cells can migrate collectively in tightly or loosely-associated groups during tissue and organ formation, during embryonic development, in tumor metastases, and in wound healing. Drosophilaborder cellsserve as an excellent genetic model of collective cell migration inside a developing tissue. During ovarian development, 6-8 cells form the border cell cluster and migrate together as a cohesive group to reach the large oocyte. Previous experiments have shown that Nuclear inhibitor of Protein Serine Threonine Phosphatase 1 (NiPP1) causes border cells to separate into single cells, rather than stay in a group, and limits their ability to migrate. NiPP1 inhibits the ...

Residual Feed Intake (RFI) is an economically relevant trait in beef cattle. Among the molecular regulatory mechanisms, microRNAs (miRNAs) are an important dimension in post-transcriptional regulation and have been associated with different biological pathways. Here, we performed differential miRNAs expression and weighted gene co-expression network analyses (WGCNA) to better understand the complex interactions between miRNAs and mRNAs expressed in bovine skeletal muscle and liver. MiRNA and mRNA expression data were obtained from Nelore steers that were genetically divergent for RFI (N = 10 [low RFI or feed efficient]; N = 10 [high RFI or feed inefficient]). Differentially expressed and hub miRNAs such ...

Background: Lipids are a class of molecules that play an important role in cellular structure and metabolism in all cell types. In the last few decades, it has been reported that long-chain fatty acids (FAs) are involved in several biological functions from transcriptional regulation to physiological processes. Several fatty acids have been both positively and negatively implicated in different biological processes in skeletal muscle and other tissues. To gain insight into biological processes associated with fatty acid content in skeletal muscle, the aim of the present study was to identify differentially expressed genes (DEGs) and functional pathways related to gene ...

James M Reecy

Background The availability of the bovine genome sequence and SNP panels has improved various genomic analyses, from exploring genetic diversity to aiding genetic selection. However, few of the SNP on the bovine chips are polymorphic in buffalo, therefore a panel of single nucleotide DNA markers exclusive for buffalo was necessary for molecular genetic analyses and to develop genomic selection approaches for water buffalo. The creation of a 90K SNP panel for river buffalo and testing in a genome wide association study for milk production is described here.

Methods The genomes of 73 buffaloes of 4 different breeds were sequenced and ...


Investigating Comt Influence On The Proactive-Reactive Stress Coping Axis In Zebrafish, Sean T. Bresnahan, Ryan Y. Wong Mar 2019

Investigating Comt Influence On The Proactive-Reactive Stress Coping Axis In Zebrafish, Sean T. Bresnahan, Ryan Y. Wong

Student Research and Creative Activity Fair

Individuals of the same species often display differences in correlated suites of behaviors which are made conspicuous when challenges – stressful, fear-inducing, etc. – are presented. In many species, a specific suite of behaviors (risk-aversion, aggression, exploration, learning, and memory) characterize an alternative set of stress coping styles (proactive and reactive). Such behaviors are regulated in the brain by specific neurotransmitters along with proteins that regulate them. One neurotransmitter regulator protein, catechol-O-methyltransferase (COMT) shows higher baseline whole-brain expression in proactive relative to reactive animals. However, it is not known whether its expression is a cause or a consequence of the stress coping ...


Synder: Inferring Genomic Orthologs From Synteny Maps, Zebulun Arendsee, Andrew Wilkey, Urminder Singh, Jing Li, Manhoi Hur, Eve Syrkin Wurtele Feb 2019

Synder: Inferring Genomic Orthologs From Synteny Maps, Zebulun Arendsee, Andrew Wilkey, Urminder Singh, Jing Li, Manhoi Hur, Eve Syrkin Wurtele

Genetics, Development and Cell Biology Publications

Ortholog inference is a key step in understanding the evolution and function of a gene or other genomic feature. Yet often no similar sequence can be identified, or the true ortholog is hidden among false positives. A solution is to consider the sequence's genomic context. We present the generic program, synder, for tracing features of interest between genomes based on a synteny map. This approach narrows genomic search-space independently of the sequence of the feature of interest. We illustrate the utility of synder by finding orthologs for the Arabidopsis thaliana 13-member gene family of Nuclear Factor YC transcription factor ...

Life Sciences Faculty Publications

The transcriptional anti-silencing and DNA-binding protein, VirB, is essential for the virulence of Shigella species and, yet, sequences required for VirB-DNA binding are poorly understood. While a 7-8 bp VirB-binding site has been proposed, it was derived from studies at a single VirB-dependent promoter, icsB. Our previous in vivo studies at a different VirB-dependent promoter, icsP, found that the proposed VirB-binding site was insufficient for regulation. Instead, the required site was found to be organized as a near-perfect inverted repeat separated by a single nucleotide spacer. Thus, the proposed 7-8 bp VirB-binding site needed to be re-evaluated. Here, we engineer ...


Mrub_3018 Is Orthologous To E. Coli B2759 (Casb), Kyle Parker, Dr. Lori Scott Feb 2019

Mrub_3018 Is Orthologous To E. Coli B2759 (Casb), Kyle Parker, Dr. Lori Scott

Meiothermus ruber Genome Analysis Project

This project is part of the Meiothermus ruber genome analysis project, which uses a collection of online bioinformatics tools to predict gene function. We studied the biological activity of the Mrub_3018 gene, which we hypothesize is orthologous to E. coli gene B2759. We predicted that Mrub_3018(DNA coordinates 3057916… 3058524) encodes the protein CasB. CasB is a protein in the CRISPR CASCADE that will function as a structural protein. When the rest of the proteins form an “S” formation CasB will connect the front and back of the “S” creating a back bone for the structure. It will help bind ...

Mrub_3019 Casa Gene Is An Ortholog To E. Coli B2760, Kelsey Heiland, Dr. Lori Scott

Meiothermus ruber Genome Analysis Project

This research is part of the Meiothermus ruber genome annotation project which aims to predict gene function with various bioinformatics tools. We investigated the function of Mrub_3019, which encodes the CasA protein involved in the multi-subunit effector complex for the CRISPR-Cas immunity system and predicted it to be an ortholog of E. coli K12 MG1655 b2760 (casA). We predicted that Mrub_3019 encodes the protein CasA, which is involved in PAM recognition of CRISPR interference pathway. Foreign DNA will bind to CasA, which signals Cas3 for helicase-mediated DNA degradation. Our hypothesis is supported by low E-values for pairwise alignment in NCBI ...

School of Arts & Sciences Theses

This study phylogenetically analyzed 30 AMY-related genes from 11 primates. The results show the gradual expansion of the AMY gene family which could have allowed primates to adapt to various ecological landscapes and maximize energy intake from starch-rich foods in periods of food scarcity.


Effects Of Temperature On Crispr/Cas System, Eddie Beckom, Dr. Lori Scott Jan 2019

Effects Of Temperature On Crispr/Cas System, Eddie Beckom, Dr. Lori Scott

Meiothermus ruber Genome Analysis Project

This project is part of the Meiothermus ruber genome analysis project, which uses a collection of online bioinformatics tools to predict gene function. We investigated the effect of temperature on the complexity of CRISPR/Cas systems in bacterial organisms across temperature classifications. We predict that temperature extremes would result in CRISPR/Cas systems with multiple operons, repeating cas genes, and complex systems. CRISPR/Cas systems can be classified into three types with a number of subtypes based on the CRISPR-associated genes, cas genes, present in a given organism. Our hypothesis is supported by the presence of multiple operons in thermophilic ...

Mrub_3020, A Paralog Of Mrub_1489, Is Orthologous To E. Coli Casc (Locus Tag B2761), Alfred Dei-Ampeh, Dr. Lori Scott

Meiothermus ruber Genome Analysis Project

This project is part of the Meiothermus ruber genome analysis project, which uses a collection of online bioinformatics tools to predict gene function. We investigated the biological functions of two genes: mrub_3020 and mrub_1489. We make two hypotheses in this investigation: a) mrub_3020 is orthologous to the gene b2761 in E. coli K12 MG1655 (a.k.a. casC); b) mrub_1489 is a paralog of mrub_3020. We also predict that the two genes encode unique proteins: mrub_3020 with DNA coordinates 3060491…3063190 encodes a CRISPR – associated helicase (Cas3) that supports the Cascade complex of the CRISPR – Cas adaptive immune system by ...


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 Jan 2019

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.

Contrasting Patterns Of Rapid Molecular Evolution Within The P53 Network Across Mammal And Sauropsid Lineages, Courtney N. Passow, Anne M. Bronikowski, Heath Blackmon, Shikha Parsai, Tonia S. Schwartz, Suzanne E. Mcgaugh

Ecology, Evolution and Organismal Biology Publications

Cancer is a threat to multicellular organisms, yet the molecular evolution of pathways that prevent the accumulation of genetic damage has been largely unexplored. The p53 network regulates how cells respond to DNA-damaging stressors. While there has been research on the p53 gene and the transcription factors it encodes, we know little about p53 network regulation. In this study, we performed comparative genetic analyses of the p53 network to quantify the number of genes within the network that are rapidly evolving and constrained, and the association between lifespan and the patterns of evolution. Based on our previous published dataset, we ...


Detection Of Beta-Lactamase Variants In Municipal Wastewater And Fresh Water, Sunil Pandey Jan 2019

Detection Of Beta-Lactamase Variants In Municipal Wastewater And Fresh Water, Sunil Pandey

Masters Theses

The occurrence and spread of antibiotic-resistant genes (ARGs) are pressing public health problems worldwide. A key factor contributing to the spread of ARGs is lateral gene transfer. Wastewater treatment plants (WWTPs) are measured hot spots of microbial diversity and resistance because they receive polluted wastewater from diverse sources and contain a variety of different environments with dense bacterial loads. Due to the overuse of antibiotics the genetic capacities of microbes have profited. This helps every source of resistance gene and every means of horizontal gene transmission to develop the multiple mechanism of resistance to each antibiotic used clinically, agriculturally, or ...

Electronic Theses and Dissertations

Microbotryum lychnidis-dioicae causes anther smut fungus in its host plant, Silene latifolia. The goal of this work is to identify and characterize the virulence determinants of this pathogen to better understand the molecular basis behind this host-pathogen interaction. This work studied for the first time the key effectors in the mechanism of infection by this fungal species. Using, yeast two-hybrid screens, I have identified the host plant interaction partners for the effector, MVLG_01732. A second effector MVLG_05720, interacts with other fungal proteins that appear to facilitate the fungal establishment and colonization during the infection. Our findings indicate that a third ...


Investigating Autophagy Dysfunction Induced By A Parkinson's Disease-Causing Mutation In Vps35, Abir Ashfakur Rahman Dec 2018

Investigating Autophagy Dysfunction Induced By A Parkinson's Disease-Causing Mutation In Vps35, Abir Ashfakur Rahman

Boise State University Theses and Dissertations

Parkinson’s Disease (PD) is an idiopathic disorder with no known cure. With number of cases steadily rising around the world, it is imperative to turn to the underlying cellular and molecular mechanisms of the disease manifestation and neurodegeneration to craft novel modes of therapy. VPS35 is one of the few genes that have identified and definitively linked to familial PD. The particular mutation that has been associated is known to cause dysfunction of a key cellular process known as autophagy. This process is primarily responsible for clearance of unwanted, damaged or misfolded proteins, among other things. Our study reveals ...

Conover, William S. Sanders, Daniel G. Peterson, James E. Frelichowski, Jodi A. Scheffler, Brian E. Scheffler, Jonathan F. Wendel

Ecology, Evolution and Organismal Biology Publications

We employed phylogenomic methods to study molecular evolutionary processes and phylogeny in the geographically widely dispersed New World diploid cottons (Gossypium, subg. Houzingenia). Whole genome resequencing data (average of 33X genomic coverage) were generated to reassess the phylogenetic history of the subgenus and provide a temporal framework for its diversification. Phylogenetic analyses indicate that the subgenus likely originated following trans-oceanic dispersal from Africa about 6.6 mya, but that nearly all of the biodiversity evolved following rapid diversification in the mid-Pleistocene (0.5-2.0 mya), with multiple long-distance dispersals required to account for range expansion to Arizona, the Galapagos Islands ...
