A Bioinformatics Methodology For The Annotation And Analysis Of Sperm Chromatin Remodeling Proteins In Sequenced Drosophila Species, Zain A. Alvi
Seton Hall University Dissertations and Theses (ETDs)
Spermatogenesis is the process by which mature functional spermatozoa are formed, and is initiated in the stem cell niche of the testes. During the post-meiotic stage of spermatogenesis, spermiogenesis, transition proteins facilitate the transformation of chromatin from a histone-based nucleosome structure to a protamine-based nucleosome structure. This study is aimed at analyzing genomic, transcript, and protein sequences of transition proteins in 13 sequenced Drosophila species. The Drosophila melanogaster spermatid specific transition protein-like protein (Tpl94D) was used as the reference sequence in this study. An extensive bioinformatics approach was employed in establishing the Tpl94D orthologs. We identified …

Theses & Dissertations
Despite multiple DNA repair pathways, DNA lesions can escape repair and compromise normal chromosomal replication, leading to genome instability. Cells utilize specialized low-fidelity Translesion Synthesis (TLS) DNA polymerases to bypass lesions and rescue arrested replication forks. TLS is a highly conserved two-step process that involves insertion of a nucleotide opposite a lesion and extension of the resulting aberrant primer terminus. The first step can be performed by both replicative and TLS DNA polymerases and, because of non-instructive DNA lesions, often results in a nucleotide misincorporation. The second step is almost exclusively catalyzed by DNA polymerase ζ …
Functional Significance Of Branch Points In Mirtrons, Britton A. Strickland
Functional Significance Of Branch Points In Mirtrons, Britton A. Strickland
Honors Theses
MicroRNAs are a heterogeneous group of small regulatory RNAs generated by many pathways. Mirtrons (miR) are a class of microRNAs produced by splicing, and some mirtrons contain a 3’ tail located downstream from the self-complementary hairpin. During RNA splicing, a loop-like “lariat” intermediate structure is created when the 5’ end of the RNA is attached to an adenine called the branch point. The goal of this project is to uncover the contribution of branch point location to the processing of tailed mirtrons into functional gene regulators. This project approaches this issue from two directions. First, branch points were identified by …
Characterization Of Vesicular Monoamine Transporter 2 And Its Role In Parkinson's Disease Pathogenesis Using Drosophila, Antonio Joel Tito Jr., Sheng Zhang
Characterization Of Vesicular Monoamine Transporter 2 And Its Role In Parkinson's Disease Pathogenesis Using Drosophila, Antonio Joel Tito Jr., Sheng Zhang
Dissertations & Theses (Open Access)
Parkinson’s disease (PD) is a progressive neurodegenerative disorder caused by the selective loss of the dopaminergic neurons in the Substantia nigra pars compacta region of the brain. PD is also the most common neurodegenerative disorder and the second most common movement disorder. PD patients exhibit the cardinal symptoms, including tremor of the extremities, rigidity, slowness of movement, and postural instability, after 70-80% of DA neurons degenerate. It is, therefore, imperative to elucidate the underlying mechanisms involved in the selective degeneration of DA neurons. Although increasing numbers of PD genes have been identified, why these largely widely expressed genes induce …
Tetrameric Photosystem I: From Initial Discovery And Characterization In Chroococcidiopsis Sp. Ts-821 To Exploration Of Its Distribution And Understanding Of Its Significance In Cyanobacteria, Meng Li
Doctoral Dissertations
Photosystem I (PSI) forms trimeric complexes in most characterized cyanobacteria. We had reported the tetrameric form of PSI in the unicellular cyanobacterium, Chroococcidiopsis sp. TS-821 (TS-821). Using Cryo-EM, a 3D model of the PSI tetramer structure at 11.5 [Angstrom] resolution was obtained and a 2D map within the membrane plane of at 6.1 [Angstrom]. In contrast to the three-fold symmetry in trimeric PSI crystal structure from T. elongatus, two different inter-monomer interactions involving PsaLs are found in the PSI tetramer. Phylogenetic analysis based on PsaL protein sequences shows that TS-821 is closely related to heterocyst-forming cyanobacteria. Additionally, this tetrameric …

Punctuated Evolution Within A Eurythermic Genus (Mesenchytraeus) Of Segmented Worms: Genetic Modification Of The Glacier Ice Worm F1f0 Atp Synthase, Shirley A. Lang
Graduate School of Biomedical Sciences Theses and Dissertations
Segmented worms (Annelida) are among the most successful animal inhabitants of extreme environments worldwide. An unusual group of Mesenchytraeus worms endemic to the Pacific Northwest of North America occupy geographically proximal ecozones ranging from low elevation temperate rainforests to high altitude glaciers. Along this altitudinal transect, Mesenchytraeus representatives from disparate habitat types were collected and subjected to deep mitochondrial and nuclear phylogenetic analyses. Evidence presented here employing modern bioinformatic analyses (i.e., maximum likelihood, Bayesian inference, multi-species coalescent) supports a Mesenchytraeus “explosion” in the upper Miocene (5-10 million years ago) that gave rise to ice, snow and terrestrial worms, derived from …
Molecular Analysis Of Ftsz-Ring Assembly In E. Coli Cytokinesis, Kuo-Hsiang Huang
Molecular Analysis Of Ftsz-Ring Assembly In E. Coli Cytokinesis, Kuo-Hsiang Huang
Dissertations, Theses, and Capstone Projects
An essential first step in bacterial division is the assembly of a cytokinetic ring (Z-ring) formed by the tubulin-like FtsZ at midcell. The highly conserved core domain of FtsZ has been reported to mediate assembly of FtsZ polymers in vivo and in vitro. Species-specific differences in the FtsZ C-terminal domain such as the FtsZ CTV region and interactions with several modulatory proteins such as ZapC and ZapD, restricted to certain bacterial classes, also serve as key determinants of FtsZ protofilament bundling. Here, we characterize (i) the roles of the FtsZ CTV region in mediating both longitudinal and lateral interactions …
Iron Acquisition Strategies Employed By Staphylococcus Lugdunensis, Jeremy R. Brozyna
Iron Acquisition Strategies Employed By Staphylococcus Lugdunensis, Jeremy R. Brozyna
Electronic Thesis and Dissertation Repository
Iron is crucial for many cellular processes including DNA synthesis and respiration. The majority of iron in mammals is in heme within hemoproteins, inside cells, or transported through circulation by the glycoprotein transferrin, which constitutes the greatest iron source in serum. Limiting iron availability is an important facet of nutritional immunity to help prevent infection.
Staphylococcus lugdunensis is a human skin commensal and opportunistic pathogen capable of causing a variety of infections, including particularly aggressive endocarditis. It is an emerging pathogen with elevated virulence compared to other species of coagulase-negative staphylococci. The versatility of S. lugdunensis to infect multiple niches …
Multi-Gene Resistance To Neonicotinoids In The Colorado Potato Beetle, Leptinotarsa Decemlineata, Emine Kaplanoglu
Multi-Gene Resistance To Neonicotinoids In The Colorado Potato Beetle, Leptinotarsa Decemlineata, Emine Kaplanoglu
Electronic Thesis and Dissertation Repository
The Colorado potato beetle, Leptinotarsa decemlineata, is a significant pest of potato, and its impact on agriculture is measured on a global scale. The beetle is mainly controlled by neonicotinoid insecticides, however, resistance development is a growing concern. Resistance to neonicotinoids is thought to involve elevated activity of detoxifying enzymes and xenobiotic transporters that break-down and excrete insecticide molecules. Here, using mRNA sequencing, I identified multiple detoxifying enzyme and xenobiotic transporter genes transcriptionally up-regulated in a neonicotinoid resistant strain of beetles. I then used RNA interference to knock down the transcript levels of the ten most promising genes in …
Incremental Phylogenetics By Repeated Insertions: An Evolutionary Tree Algorithm, Peter Revesz, Zhiqiang Li
Incremental Phylogenetics By Repeated Insertions: An Evolutionary Tree Algorithm, Peter Revesz, Zhiqiang Li
School of Computing: Faculty Publications
We introduce the idea of constructing hypothetical evolutionary trees using an incremental algorithm that inserts species one-by-one into the current evolutionary tree. The method of incremental phylogenetics by repeated insertions lead to an algorithm that can be used on DNA, RNA and amino acid sequences. According to experimental results on both synthetic and biological data, the new algorithm generates more accurate evolutionary trees than the UPGMA and the Neighbor Joining algorithms.
Functional And Expression Analysis Of A Novel Basement Membrane Degrader In Drosophila Melanogaster, Christopher J. Fields
Functional And Expression Analysis Of A Novel Basement Membrane Degrader In Drosophila Melanogaster, Christopher J. Fields
Masters Theses & Specialist Projects
The Srivastava Lab is focused on the identification and characterization of genes that play a role in basement membrane remodeling. Previously, we identified putative basement membrane degraders through a genetic screen. One such gene has been suggested to play a role in the maintenance of the stem cell niche in Drosophila melanogaster, but no other information about the role this gene plays in development or disease has been published. Here, data are presented from experiments utilizing Drosophila genetics and immunohistochemistry that provide important insights on the biological role of this gene.
Collagenase activity was up-regulated upon overexpression of this gene, …

Here we report expression and characterization of recombinant bacterial phytase PaPhyC from Pantoea sp. Codon-optimized phytase gene was expressed E.coli BL21 pLysS and protein expression was confirmed by Western blotting. Recombinant protein expressed in E.coli has high phytase activity. We show that PaPhyC recombinant phytase has different molecular masses when expressed in bacteria and plants, suggesting that possible protein glycosylation in plants may influence its overall size.

The Role Of Daf-19 In Non-Ciliated Neurons: How Is Neural Development Regulated By Different Daf-19 Isoforms?, Zabdiel Ek Vazquez
The Role Of Daf-19 In Non-Ciliated Neurons: How Is Neural Development Regulated By Different Daf-19 Isoforms?, Zabdiel Ek Vazquez
Lawrence University Honors Projects
A degenerative disease-like phenotype, specifically reduction in synaptic protein levels in adult worms, is correlated with loss-of-function of the only RFX transcription factor gene, daf-19, in C. elegans. This gene encodes four known transcription factor isoforms, two of which are correlated with particular functions. The DAF-19C isoform activates genes responsible for cilia development, while DAF-19M is needed for cilia specification in males. A comparison of the transcriptome of daf-19 null and isogenic wild type adult worms suggests both positive and negative regulation of gene expression is correlated with the presence of DAF-19 proteins. We have assessed DAF-19 regulation …

Hiv Vaccines: Progress, Limitations And A Crispr/Cas9 Vaccine, Omar A. Garcia Martinez
Biology: Student Scholarship & Creative Works
ABSTRACT: The HIV-1 pandemic continues to thrive due to ineffective HIV-1 vaccines. Historically, the world’s most infectious diseases, such as polio and smallpox, have been eradicated or have come close to eradication due to the advent of effective vaccines. Highly active antiretroviral therapy is able to delay the onset of AIDS but can neither rid the body of HIV-1 proviral DNA nor prevent further transmission. A prophylactic vaccine that prevents the various mechanisms HIV-1 has to evade and attack our immune system is needed to end the HIV-1 pandemic. Recent advances in engineered nuclease systems, like the CRISPR/Cas9 system, have …
Epigenetic Characterization Of Human Retina Cells, Nicholas R. Dunham
Epigenetic Characterization Of Human Retina Cells, Nicholas R. Dunham
Senior Honors Projects, 2010-2019
DNA methylation is an epigenetic modifier that modulates gene expression in plant and vertebrate genomes. The aim of this study was to characterize the role of DNA methylation in the human retina, particularly within rod and cone photoreceptor retinal neurons. Previous studies investigating DNA methylation in murine retinal cells and retina-derived human retinoblastoma immortalized cell culture lines demonstrate an inverse relationship between DNA methylation and transcriptional activity. Here, we used gene-specific bisulfite pyrosequencing analysis to measure DNA methylation in the genomes of human ocular cells in an effort to characterize the role of this important epigenetic modifier. These results can …
Investigation Of A Mycobacteriophage Transcription Repressor, Kathryn Orban
Investigation Of A Mycobacteriophage Transcription Repressor, Kathryn Orban
Honors Thesis
Mycobacteriophage HelDan is a lysogenic, or temperate, phage (virus) of the bacterium Mycobacterium smegmatis, which is a fast-growing, close relative of Mycobacterium tuberculosis, the causative agent of tuberculosis. The phage replication cycle is dependent on time-coordinated gene expression events. In order to study the regulation of gene expression during phage replication, HelDan protein gp73, a putative transcriptional repressor, was studied. Characterization of gp73 structure and function, such as DNA binding activity and affinity, was done using both bioinformatics and biochemical analyses. To this end, the gene encoding gp73 was cloned and the ability of the recombinant gp73 protein …
The Roles Of Malt1 In Nf-Κb Activation And Solid Tumor Progression, Deng Pan
The Roles Of Malt1 In Nf-Κb Activation And Solid Tumor Progression, Deng Pan
Dissertations & Theses (Open Access)
The transcription factor NF-κB plays a central role in many aspects of biological processes and diseases, such as inflammation and cancer. Although it has been suggested thatNF-κB is critical in tumorigenesis and tumor progression, the molecular mechanism by which NF-κB is activated in solid tumor remains largely unknown. In the current work, we focus on growth factor receptor-induced NF-κB activation and tumor progression, including epidermal growth factor receptor (EGFR)-induced NF-κB in lung cancer and heregulin receptor (HER2)-induced NF-κB in breast cancer. We found that Mucosa-associated lymphoma translocation protein 1 (MALT1), also known as paracaspase, is required for EGFR-induced NF-κB activation …
Engineering A Mutation In The Heparin Binding Pocket Of The Human Fibroblast Growth Factor, Roshni Patel
Engineering A Mutation In The Heparin Binding Pocket Of The Human Fibroblast Growth Factor, Roshni Patel
Chemistry & Biochemistry Undergraduate Honors Theses
Fibroblast growth factors (FGFs) are family of proteins that belong to a group of growth factors that are found in mammals and play an important role in angiogenesis, differentiation, organogenesis, and tissue repair. In summary, their main functionality is involved in cell division and proliferation. Because FGFs plays such a vital role in cell proliferation, they are mainly involved in the process of wound healing and injuries. FGF binds to its ligand, heparin—a heavily sulfated glycosaminoglycan. The binding of heparin to FGF occurs through electrostatic interactions, specifically between the negatively charged sulfate groups on heparin and positively charged residues such …

Papers in Herpetology
The state of Florida, USA, has more introduced herpetofauna than any other governmental region on Earth. Four species of nonnative crocodilians have been introduced to Florida (all since 1960), one of which is established. Between 2000–2014 we field-collected three nonnative crocodilians in Miami-Dade County, Florida, and one in Hendry County, Florida. We used DNA barcoding and molecular phylogenetics to determine species identification and native range origin. Also, we described diet, movement, and growth for one crocodile. Our molecular analyses illustrated that two of the crocodiles we collected are most closely related to Nile Crocodiles (Crocodylus niloticus) from South Africa, suggesting …

Staufen Negatively Modulates Microrna Activity In Caenorhabditis Elegans, Zhiji Ren, Isana Veksler-Lublinsky, David Morrissey, Victor Ambros
Victor R. Ambros
The double-stranded RNA-binding protein Staufen has been implicated in various post-transcriptional gene regulatory processes. Here we demonstrate that the Caenorhabditis elegans homolog of Staufen, STAU-1, functionally interacts with microRNAs. Loss-of-function mutations of stau-1 significantly suppress phenotypes of let-7 family microRNA mutants, a hypomorphic allele of dicer and a lsy-6 microRNA partial loss-of-function mutant. Furthermore, STAU-1 modulates the activity of lin-14, a target of lin-4 and let-7 family microRNAs, and this modulation is abolished when the 3' untranslated region of lin-14 is removed. Deep sequencing of small RNA cDNA libraries reveals no dramatic change in the levels of microRNAs, or other …

It catalyzes the conversion of UDP-3-O-(3-hydroxymyristoyl)-α-D-glucosamine + a(3R)-3-hydroxymyristoyl-[acp] → a holo-[acyl-carrier protein] + UDP-2-N,3-O-bis[(3R)-3-hydroxytetradecanoyl]-α-D-glucosamine. The E. coli K12 MG1655 ortholog is predicted to be b0179, which …
