Integrated with molecular biology techniques, the study further quantifies TRIP13 expression in progressive pancreatic cancer …

Analysis Of Botulinum Toxin A And Interacting Proteins In Skeletal Muscle Cells: An Investigation Into The Mechanisms Of Botulinum Toxin A As A Treatment For Chronic Exertional Compartment Syndrome, Lauren R. Kee

ELAIA

Background Chronic exertional compartment syndrome (CECS) is a condition in which muscle tissue expands against the surrounding fascia during activity and is compressed along with the nerves and blood vessels within the muscle compartment, leading to abnormally high intracompartmental pressure (ICP) and debilitating pain. Treatment typically includes fasciotomy, which results in significant levels of CECS recurrence; however, botulinum toxin A (BoNT-A) injection has recently been seen to decrease both ICP and pain through an unknown mechanism with little to no recurrence. Methods In this study, PyRosetta was used to model the probability of docking interaction between BoNT-A light or heavy …

Investigating Optimal Laboratory Growth Conditions Of Gracilibacillus Halotolerans In Media Supplemented With Salt, Isaac Young

Annual Research Symposium

As interest continues to grow in the field of persister cells and their morphology, there arises an ever-evolving desire to further understand specific strains of bacteria that exemplify the qualities of seemingly anomalous survival regardless of anti-bacterial treatment. In the case of the Gracilibacillus halotolerans, a halotolerant extremophile extracted from the Great Salt Lake with known persistent characteristics, uncovering its optimal growth conditions was essential for future investigations. Identifying the optimal salinity for the growth of G. halotolerans will allow us to standardize our growth methods, uncover several mechanisms of saline tolerance, and add to future investigations of persistence with …

Evidence That Aquaporin 11 (Aqp11) In The Spiny Dogfish (Squalus Acanthias) May Represent A Pseudogene, Christopher P. Cutler, Meghan Canicatti, Esosa Omoregie

Department of Biology Faculty Publications

Various attempts to amplify an AQP11 cDNA from tissues of the spiny dogfish (Squalus acanthias) were made. Two pairs of deoxy-inosine-containing degenerate primers were designed based on conserved amino acid sequences from an AQP11 alignment. These primers yielded some faint bands from gill cDNA that were sequenced. Blast searches with the sequences showed they were not AQP11. An elasmobranch AQP11 nucleotide sequence alignment was produced to identify conserved regions to make further degenerate primers. One primer pair produced a short 148 bp fragment showing particularly strong amplification in gill and intestine. It was sequenced and represented a piece of the …

Studying The Genes And Conditions That Influence Root Development, Tessa Holtkamp, Hannah Ordonez Webb

Undergraduate Research Symposium

Root development in plants is essential for their survival and understanding how hormones influence their development can explain how plants grow under different circumstances. Researching how Indole-3-butyric acid (IBA), a hormone that induces root production, affects the plant model Arabidopsis thaliana helps explain the hormone's effect in agricultural crop systems. To understand root pathways, we performed assays on mutant lines of Arabidopsis by growing plants on varying concentrations of IBA. For wild-type and mutant lines, phenotyping experiments like branching of roots, lengths of stems, and root length were conducted along with PCR and restriction digest genotyping experiments to compare their …

C. Compactum Acts As A Comprehensive Climate Archive And Ecological Foundation In The Labrador Sea, Sadie Heckman

CMC Senior Theses

Clathromorphum compactum, a species of crustose coralline algae (CCA), is incredibly valuable for the future of high latitude ocean health, both as a comprehensive archive of changing ocean conditions, and ecologically as a foundational species for promoting biodiversity. Previous work establishes C. compactum as an effective climate proxy, and its life history provides several advantages for this use. C. compactum grow in nongeniculate, generally radial formations on hard substrates, over a wide distribution in mid-to-high latitude oceans and at subtidal depth ranges. Indeterminate growth leads to extreme longevity in C. compactum (Halfar et al., 2008), and growth rates are relatively …

Can Biology Define A Human Life?, Katelyn De Leon

Regis University Student Publications (comprehensive collection)

I grew up contemplating the concept of life. From my Catholic grandmother to my pediatrician mother, I always received mixed perspectives on the hot topics of abortions, vaccines, and embryo use. I found that the controversy lies in an ambiguous, mixed understanding of what constitutes a human life. From biochemical approaches to extraterrestrial life forms and spirituality there is no clear, coherent all-encompassing definition of life. However, that does not mean we can merely agree to disagree. The concept of a human life has drastic implications on our everyday lives. An insufficient definition has, and will continue to, diminish quality …

Reducing Food Scarcity: The Benefits Of Urban Farming, S.A. Claudell, Emilio Mejia

Journal of Nonprofit Innovation

Urban farming can enhance the lives of communities and help reduce food scarcity. This paper presents a conceptual prototype of an efficient urban farming community that can be scaled for a single apartment building or an entire community across all global geoeconomics regions, including densely populated cities and rural, developing towns and communities. When deployed in coordination with smart crop choices, local farm support, and efficient transportation then the result isn’t just sustainability, but also increasing fresh produce accessibility, optimizing nutritional value, eliminating the use of ‘forever chemicals’, reducing transportation costs, and fostering global environmental benefits.

This study aimed to select and characterize endophytic bacteria producing bioactive compounds that inhibit the growth of F. proliferatum. The endophytic bacteria used were isolated from the roots, stems, leaves, and soil of shallot plants from healthy and diseased shallot farming fields. The endophytic bacteria were selected using the dual culture method and extracted using ethyl acetate solvent. The results of the 16S rRNA identification suggested that isolate ABP5.2 is similar to Pseudomonas …

Repositioning Propranolol To Block Mitogenic Signaling In Breast Cancer, Alexa Noel Montoya

Open Access Theses & Dissertations

Breast cancer is the second most diagnosed cancer among women and is about 30% of all new cases of female cancers each year. It is projected that 1 in 8 every U.S. woman (about 13%) develop invasive breast cancer over the course of her lifetime. While advances in cancer research have made it possible to elucidate several breast cancer genomic subtypes, and develop new novel therapies, many of these agents are associated with significant toxicity, as well as high costs. A retrospective cross-sectional study of 404 breast cancer patients was performed to determine the effect of β-blocker usage on tumor …

Quantifying The Role Of Water Quality On Nitrogen Cycling In A Trophic Estuary, Kayla Gonzalez-Boy

Symposium of Student Scholars

Jobos Bay Estuary is an intertidal, tropical estuary located in southern Puerto Rico. The estuary covers about 12 km² and has a variety of habitats, such as seagrass beds, mangroves, mud flats, and coral reefs, which play important roles in sediment trapping and water quality maintenance. Seagrasses also serve as nursery and feeding grounds and provide shelter for macrofauna. Currently, the role of seagrasses and water quality on nitrogen (N) cycling in trophic estuaries is not well constrained. Understanding variations in sediment-based effects on N cycling rates and transformations, and how they are associated with water quality, is an …

Elucidating The Priming Mechanism Of Clpxp Protease By Single-Domain Response Regulator Cpdr In Caulobacter Crescentus, Kimberly E. Barker

Masters Theses

In Caulobacter crescentus, progression through the cell cycle is regulated by the AAA+ protease ClpXP, and there are several classes of cell-cycle substrates that require adaptors in order to be degraded. CpdR, a single domain-response regulator, binds the N-terminal domain of ClpXP and primes the protease for degradation of downstream factors (Lau et al., 2015). The ability of CpdR to bind ClpX is regulated by its phosphorylation state. In the unphosphorylated state, CpdR binds ClpXP and guides its localization to the cell pole during the swarmer to stalked transition, where CpdR is mediates degradation of substrates such as PdeA. …

Targeting Bet Proteins Downregulates Mir-33a To Promote Synergy With Pim Inhibitors In Cmml, Christopher T. Letson

USF Tampa Graduate Theses and Dissertations

Chronic Myelomonocytic Leukemia (CMML) is a rare myeloid malignancy with a dismal prognosis and no therapeutic options which are capable of altering the natural course of the disease. There remains a significant need for novel therapies that are able to meaningfully improve patient outcomes. In this study we explore the effectiveness of Bromodomain and Extra-Terminal domain protein inhibitor (BETi) combinations in CMML. Preclinical studies in myeloid neoplasms have demonstrated efficacy of BETi. However, BETi demonstrate poor single agent activity in clinical trials. Several studies suggest that combinations with other anti-cancer inhibitors may enhance the efficacy of BETi. To nominate BETi …

Great Lakes Institute for Environmental Research Publications

For Microcystis aeruginosa PCC 7806, temperature decreases from 26 °C to 19 °C double the microcystin quota per cell during growth in continuous culture. Here we tested whether this increase in microcystin provided M. aeruginosa PCC 7806 with a fitness advantage during colder-temperature growth by comparing cell concentration, cellular physiology, reactive oxygen species damage, and the transcriptomics-inferred metabolism to a non-toxigenic mutant strain M. aeruginosa PCC 7806 ΔmcyB. Photo-physiological data combined with transcriptomic data revealed metabolic changes in the mutant strain during growth at 19 °C, which included increased electron sinks and non-photochemical quenching. Increased gene expression was observed for …

Effects Of Growth Rate On Peptidoglycan Crosslink Density Of E. Coli Using Fluorescent Labeling, Morgan Olszewski

Harrisburg University Research Symposium: Highlighting Research, Innovation, & Creativity

Peptidoglycan (PG) is a polymer composed of polysaccharides and crosslinked peptide chains found in bacterial cell walls. It helps to protect the cell from environmental stress and maintain cell morphology throughout its life cycle and further generations. The PG is made up of two sugars, N-acetyl muramic acid (NAM) and N-acetyl glucosamine (NAG). NAM and NAG are connected by glycosidic linkages to form repeated chains. The chains are formed in layers, which are interconnected via a polypeptide stem linked by a peptide bridge. During cell growth, continuous turnover of existing PG occurs by severing existing crosslinks, inserting new PG into …

Short-Term Versus Long-Term Effects Of Nitrogen Addition And Warming On Ecosystem N Dynamics In A Grass-Dominated Temperate Old Field, Benjamin F. A. Souriol

Electronic Thesis and Dissertation Repository

Increased atmospheric nitrogen (N) deposition and climate warming are both anticipated to influence the ecosystem N dynamics of northern temperate ecosystems substantially over the next century. Nevertheless, in field experiments with N addition and warming treatments, temporal scale can play an important role in determining the extent of treatment effects on N dynamics, and it is unclear to what extent the results of short-term studies can be extrapolated to responses over longer time scales. I compared the short-term versus long-term effects of N addition and warming on net N mineralization, N leaching, and N retention in a grass-dominated old field. …

A Colonial-Nesting Seabird Shows Limited Heart Rate Responses To Natural Variation In Threats Of Polar Bears, Erica A. Geldart, Oliver P. Love, Andrew F. Barnas, Christopher M. Harris, H. Grant Gilchrist, Christina A.D. Semeniuk

Great Lakes Institute for Environmental Research Publications

Several predator-prey systems are in flux as an indirect result of climate change. In the Arctic, earlier sea-ice loss is driving polar bears (Ursus maritimus) onto land when many colonial nesting seabirds are breeding. The result is a higher threat of nest predation for birds with potential limited ability to respond. We quantified heart rate change in a large common eider (Somateria mollissima) breeding colony in the Canadian Arctic to explore their adaptive capacity to keep pace with the increasing risk of egg predation by polar bears. Eiders displayed on average higher heart rates from baseline when polar bears were …

Novel Therapy Targeting Mutant-Krasg12d And Galectin-1 In Pancreatic Cancer, Ana I. Martinez Bulnes, Sheema Khan, Dan Ninroy, Poornima Devi Shaji, Swathi Holla, Murali M. Yallapu, Subhash C. Chauhan

Research Symposium

Introduction: Although, surgical resection and chemotherapy are the gold standard for treating Pancreatic Ductal Adenocarcinoma (PDAC), low patient survival rate remains the problem. The activating point mutation of the KRAS on codon-12 is present in 70–95% of PDAC cases and so far, no success has been achieved to inhibit KRAS. KRASG12D regulates cell proliferation, differentiation, apoptosis. Recent preliminary and published studies show high Galectin-1 (Gal-1) levels in both pancreatic cancer and stromal cells, which modulate tumor microenvironment and metastasis. Additionally, genetic deletion of gal1 inhibits metastasis and improves survival in KRAS mouse model of PDAC (1). Therefore, our objective is …

Identification Of Tectorigenin As A Natural Pro-Hypoxia Compound: Implications In Modulation Of Cellular Differentiation And Senescence, Mallika Khurana, Renu Wadhwa, Sunil Kaul

Research Symposium

Background: Hypoxia, a suboptimal level of oxygen, evokes stress response in cells and activated hypoxia signaling has been largely established as a pro-metastasis and pro-angiogenic factor for tumor cells. On the other hand, age-related neurodegenerative disorders are characterized by hypoxic environment, accumulation of molecular garbage and induction of premature senescence. Several recent studies have reported anti-stress impact of the intermittent induction of hypoxia signaling in these cells.

Methods: Screening of a phytochemical library using Hypoxia Responsive Element (HRE) driven luciferase as a reporter was carried out to identify hypoxia-modulating phytochemicals. Activation of HIF-1a (master regulator of hypoxia signaling) was validated …

Determination Of Hfe C282y Mutation And Its Association With The Iron Status And Viral Load In Hiv Patients From Reynosa, Tamaulipas, Juan Carlos Hernández, Marisol Rosas Díaz, Esperanza Milagros García Oropesa, Santos Graciela Montemayor Beltrán, Juana Díaz García, Imelda Ramírez Puente

Research Symposium

Background: The HFE protein has a fundamental role in iron homeostasis, the HFE C282Y mutation prevents the specific function of the protein, causing greater intestinal absorption of iron and intracellular accumulation. The HIV virus causes a disease that attacks the cells of the immune system, mainly CD 4 T lymphocytes inducing their destruction and immunosuppression of the patient. Some viruses have the ability to disrupt cellular metabolic processes during their own replication, such is the case of HIV-1, which is involved in alteration of iron metabolism resulting in an overload of iron.

Methods: An exploratory, descriptive, cross-sectional and prolective study …

Rna World And The Development Of Rna Protocells, Benjamin C. Mayfield

PANDION: The Osprey Journal of Research and Ideas

Origins of life research, also known as pre-biotic chemistry or astrobiology, aims to unravel the mystery of the first cell’s origin on Earth. This interdisciplinary field encompasses biology, chemistry, and physics, with the primary goal of understanding the conditions necessary for life to emerge from abiotic environments. The RNA world hypothesis suggests that early life initially used RNA instead of DNA to store genomic information and for enzymatic functions. Protocells, membrane-bound entities with metabolic processes and self-replication capabilities, likely preceded the emergence of true cells. The challenges associated with RNA world is currently an active field of research. Advancements in …

Recent MPOX viral resurgences have mobilized public health agencies around the world. Recognizing the significant risk of MPOX outbreaks, large-scale human testing, and immunization campaigns have been initiated by local, national, and global public health authorities. Recently, traditional clinical surveillance campaigns for MPOX have been complemented with wastewater surveillance (WWS), building on the effectiveness of existing wastewater programs that were built to monitor SARS-CoV-2 and recently expanded to include influenza and respiratory syncytial virus surveillance in wastewaters. In the present study, we demonstrate and further support the finding that MPOX viral fragments agglomerate in the wastewater solids fraction. Furthermore, this …

A Combined Microscopy And Single-Cell Sequencing Approach Reveals The Ecology, Morphology, And Phylogeny Of Uncultured Lineages Of Zoosporic Fungi, Kensuke Seto, D. Rabern Simmons, C. Alisha Quandt, Thijs Frenken, Alden C. Dirks, Rebecca A. Clemons, Katelyn M. Mckindles, R. Michael L. Mckay, Timothy Y. James

Great Lakes Institute for Environmental Research Publications

Environmental DNA analyses of fungal communities typically reveal a much larger diversity than can be ascribed to known species. Much of this hidden diversity lies within undescribed fungal lineages, especially the early diverging fungi (EDF). Although these EDF often represent new lineages even at the phylum level, they have never been cultured, making their morphology and ecology uncertain. One of the methods to characterize these uncultured fungi is a single-cell DNA sequencing approach. In this study, we established a large data set of single-cell sequences of EDF by manually isolating and photographing parasitic fungi on various hosts such as algae, …
