Seasonal Stem Loss And Self-Thinning In Low Marsh Spartina Alterniflora In A New England Tidal Marsh, Clara Chaisson, Chad C. Jones, R. Scott Warren

Botany Faculty Publications

Dense monocultures of the grass Spartina alterniflora dominate the low marsh in typical New England tidal marshes. These marshes provide a number of important ecosystem services; thus, it is important to understand the factors that influence S. alterniflora productivity. End of season live biomass is often used to estimate S. alterniflora productivity, but this measure fails to account for stems lost within the growing season and may lead to a significant underestimate. We explored two possible factors that may influence S. alterniflora stem loss within the growing season: 1) density-dependent mortality (self-thinning), and 2) the physical force of moving water …

Design Of A Synthetic Temperature-Activated Epigenetic Biocontainment System, Owen Rivers Page

Theses and Dissertations

The need for an internal control to govern engineered strain survival is becoming apparent when considering the biosafety and ethics within biotechnological research. Using understudied regulatory elements known as RNA thermometers (RNATs) that can modulate protein translation based on temperature changes and a Type II restriction modification system, we posit the creation of a synthetic temperature-activated epigenetic biocontainment system, termed the ‘sentinel switch’. We have mined a wide variety of bacteria from Yersinia pestis to Synechocystis sp. looking for novel RNATs. A complementary synthetic biology approach based on library generation and screening of chimeric RNATs (ChRNATs) was also conducted. RNATs …

Identification Of Novel Phosphorylation Sites In Sars-Cov-2 Nucleocapsid Protein, Josie Daldegan Rezende

Theses and Dissertations

COVID-19, the 2019 disease outbreak, continues to cause severe mortality worldwide. Fast and reliable tests that identify the SARS-CoV-2 virus, which is responsible for causing the COVID-19 disease, are crucial for controlling the spread of the virus. Antigen tests are ideal for the rapid diagnosis of COVID-19. Current antigen tests for COVID-19 detect the SARS-CoV-2 nucleocapsid (N) protein. The nucleocapsid is the most abundant protein produced by the virus upon infection, which makes it a superior target for detection by an antigen test. Nucleocapsid proteins from several coronaviruses, including SARS, have previously been shown to be modified by posttranslational modification …

Repressive Interactions Between Transcription Factors Separate Different Embryonic Ectodermal Domains., Steven L. Klein, Andre L P Tavares, Meredith Peterson, Charles H Sullivan, Sally A. Moody

Anatomy and Regenerative Biology Faculty Publications

The embryonic ectoderm is composed of four domains: neural plate, neural crest, pre-placodal region (PPR) and epidermis. Their formation is initiated during early gastrulation by dorsal-ventral and anterior-posterior gradients of signaling factors that first divide the embryonic ectoderm into neural and non-neural domains. Next, the neural crest and PPR domains arise, either

Phage Hunters: The Discovery Of Two Novel Bacteriophages That Infect Gordonia Rubripertincta, Sarah Ballarin, Neel Balusa, Melissa Bell, Samia Caballero, Joshua Chan, Maria Farez, Ashley J. Guillen-Tapia, Nashrah Pierre-Louis, Victoria Polishuk, Bhavya Soni, Julie Torruellas Garcia, Katie E. Crump

Sea-Phages

Antibiotic resistance is a global healthcare concern because it poses a threat to effectively treating bacterial infections and the need for alternative therapeutics are urgently required. Phage therapy, which uses viruses to treat bacterial infections, is a promising alternative to conventional antibiotics. Phages have also been widely used in the food industry to prevent microbial growth on certain foods and are currently being explored as a method for bioremediation of oil spills and wastewater treatment. Although phages are ubiquitous in nature, many have yet to be discovered. Through the SEA-PHAGES (Science Education Alliance-Phage Hunters Advancing Genomics and Evolutionary Science) program …

Turkish Journal of Biology

BEX family genes are expressed in various tissues and play significant roles in neuronal development. A mouse model of Bex3 gene knock-out was generated in this study, using the CRISPR-Cas9 system. Transcriptomic analysis of the brain was performed to identify genes and pathways under Bex3 regulation. Essential biological functions under the control of Bex3 related to brain development were identified. Ninety-five genes were differentially expressed under Bex3-/- regulation, with 53 down and 42 up. Among down-regulated genes, LOC102633156 is a member of zf-C2H2, Xlr3a is an X-linked lymphocyte regulated gene, LOC101056144 is a hippocampal related gene, 2210418O10Rik and Fam205a3 are …

Noncoding Rnas In Apoptosis: Identification And Function, Özge Tüncel, Merve Kara, Bi̇lge Yaylak, İpek Erdoğan, Bünyami̇n Akgül

Turkish Journal of Biology

Apoptosis is a vital cellular process that is critical for the maintenance of homeostasis in health and disease. The derailment of apoptotic mechanisms has severe consequences such as abnormal development, cancer, and neurodegenerative diseases. Thus, there exist complex regulatory mechanisms in eukaryotes to preserve the balance between cell growth and cell death. Initially, protein-coding genes were prioritized in the search for such regulatory macromolecules involved in the regulation of apoptosis. However, recent genome annotations and transcriptomics studies have uncovered a plethora of regulatory noncoding RNAs that have the ability to modulate not only apoptosis but also many other biochemical processes …

Modeling Of C-Terminal Tail Of Human Sting And Its Interaction With Tank-Binding Kinase 1, Rahaf Ata Ouda Al-Masri, Hajara Audu-Bida, Şebnem Eşsi̇z

Turkish Journal of Biology

Stimulator of interferon genes (STING) plays a significant role in a cell's intracellular defense against pathogens or self-DNA by inducing inflammation or apoptosis through a pathway known as cGAS-cGAMP-STING. STING uses one of its domains, the C-terminal tail (CTT) to recruit the members of the pathway. However, the structure of this domain has not been solved experimentally. STING conformation is open and more flexible when inactive. When STING gets activated by cGAMP, its conformation changes to a closed state covered by 4 beta-sheets over the binding site. This conformational change leads to its binding to Tank-binding kinase 1 (TBK1). TBK1 …

Ubiquitin Specific Protease 7 Maintains Pluripotency Of Mouse Embryonic Stem Cells Through Stabilization Of Ss-Catenin, Taha Bartu Hayal

Turkish Journal of Biology

Embryonic stem cells (ESCs), which are derived from the undifferentiated inner cell mass of the embryo, can differentiate every cell type of the body regarding their pluripotency. Therefore, human or mouse ESCs can be used as an unlimited cell source for numerous researches or therapeutical approaches. However, pluripotency maintenance of ESCs during in vitro culture is challenging because of their endless differentiation capacity. In the current study, the effect of USP7 on pluripotency maintenance of mouse ESCs (mESCs) has been investigated with the help of cell viability assay, morphological analysis, alkaline phosphatase (ALP) staining, qPCR analysis, and Western Blotting. 600 …

P110Α Activity At The M-To-G1 Transition Is Critical For Cellular Proliferation And Reentry Into The Cell Cycle, Onur Çi̇zmeci̇oğlu

Turkish Journal of Biology

Phosphoinositide 3-kinase (PI3K) signaling pathway is essential for normal physiology and is impaired in diseases such as premalignant hyperproliferative disorders, primary immunodeficiency, metabolic disorders, and cancer. Although the core PI3K pathway components are known today, a long-standing gap in our knowledge of PI3K signaling concerns how distinct PI3K isoforms and their activity patterns contribute to the functional consequences of pathway upregulation. In order to address this issue, we devised a molecular genetic cell model, which allowed temporal regulation of the indispensable PI3K isoform, p110α in distinct stages of the cell cycle. We found that late M and early G1 …

Cytoplasmically Localized Trna-Derived Fragments Inhibit Translationin Drosophila S2 Cells, Syed Muhammad Hamid, Bünyami̇n Akgül

Turkish Journal of Biology

Transfer ribonucleic acids (tRNAs) serve not only as amino acid carriers during translation but also as a template for the biogenesis of short fragments that can regulate gene expression. Despite recent progress in the function of tRNA-derived fragments (tRFs), their intracellular localization, protein partners, and role in regulating translation are not well understood. We used synthetic tRFs to investigate their localization and function in Drosophila S2 cells. Under our experimental setting, all synthetic tRFs tested were localized at distinct sites within the cytoplasm in a similar manner in Drosophila S2 cells. Cytoplasmically-localized tRFs were positioned in close proximity to GW182 …

Turkish Journal of Biology

Stathmin1 (STMN1) has been proposed as a possible prognostic marker and a potential therapeutic target for some cancers. We aimed to analyze the changes in autophagy, invasion, apoptosis-related genes in prostate cancer (PCa) cell line (PC-3), after small interfering RNA (siRNA)-mediated STMN1 silencing, and also the relationships of STMN1 expression, clinicopathological parameters, and survival (OS) in PCa cases. The STMN1 expressions were analyzed, immunohistochemically, in formalin-fixed paraffin-embedded 75 PCa and 15 benign prostatic hypertrophy (BPH) tissues. The correlation between the levels of expression STMN1, clinicopathological features, and OS was determined in PCa cases. The siRNA-mediated STMN1 incubated PC-3 cells were …

Transcriptome Sequencing Reveals Circrna Expression Profile In Parkinson's Disease-Like Mice After Aerobic Exercise, Tianlun Fan, Xiating Li, Chuan Fu, Lichun Sun

Turkish Journal of Biology

Parkinson's disease (PD) is a common complex neurodegenerative disease, and aerobic exercise (EX) has potential to improve motor dysfunction. This study aimed to explore whether EX acts on PD in mice mode. Mice were administered 1-methyl-4-phenyl- 1,2,3,6-tetrahydropyridine (MPTP) and subjected to a 4-week physical exercise regimen (EX-PD group) and underwent RNA-Seq. Here, MPTP caused PD, which was characterized by neuron shrinkage and behavioral deficits, whereas EX improved PD by rescuing neuronal survival and motor function in mice. Moreover, circRNA expression profiles identified a total of 142 differentially expressed circRNAs (DEcircRNAs) between PD and EX-PD group. These DEcircRNAs were mainly involved …
