Laboratories were shut down or only a limited number of people were allowed to enter to conduct the necessary research. This paper discusses how the COVID-19 pandemic affected research process and experiments within various aspects of the …

Parallels Between Internet And Stimulant Drug Addiction, Yashica Bhuvane

Mako: NSU Undergraduate Student Journal

This analysis explores how stimulant addictions—specifically cocaine, methamphetamines, and nicotine—impact the brain's reward system, comparing these effects with those seen in Internet Addiction (IA). Drawing from functional magnetic resonance imaging (fMRI) studies, it assesses changes in key brain regions involved in reward processing, craving, and cognitive control related to these addictive behaviors. The analysis investigates how each stimulant affects dopaminergic transmission and disrupts reward circuitry, highlighting both similarities and differences in brain activation patterns linked to addiction. By comparing these patterns with those seen in IA, the analysis aims to identify which stimulant most closely resembles the neural disruptions associated …

Discerning The Role Of Microtubule Acetylation During Hiv-1 Infection, Drew Michael Lichon

Dissertations

The host-pathogen interactions underlying Human Immunodeficiency Virus type 1 (HIV-1) infection are complex and involve the exploitation of host cellular machinery. This thesis investigates the roles of dynein adaptors, microtubule acetylation, and TRIM69-mediated restriction in HIV-1 infection. Through a series of detailed experiments, we explore how HIV-1 utilizes multiple dynein adaptors, such as BICDR1 and Hook3, for intracellular transport, and reveal that these adaptors are critical for efficient viral trafficking. Conversely, the knockdown of Ninein surprisingly enhances HIV-1 infectivity, suggesting a nuanced regulatory role for this adaptor in viral transport. Further, this thesis challenges the prevailing paradigm that microtubule acetylation …

This work presents an innovative, automated, and cost-effective tape placement system that extends traditional methods beyond carbon fiber prepreg. We developed a customized tape print module (TPM) integrated with a robotic arm, enabling precise and versatile tape placements. Our system supports non-linear toolpaths, complex patterns, and controllable placements on multi-plane surfaces, creating overhangs without support. We demonstrate circuit printing with copper tape …

Il-1Β In Neoplastic Disease And The Role Of Its Tumor-Derived Form In The Progression And Treatment Of Metastatic Prostate Cancer, Yetunde Oyende, Luke Taus, Alessandro Fatatis

Kimmel Cancer Center Faculty Papers

Since its discovery, IL-1β has taken center stage as a key mediator of a very broad spectrum of diseases revolving around immuno-mediated and inflammatory events. Predictably, the pleiotropic nature of this cytokine in human pathology has led to the development of targeted therapeutics with multiple treatment indications in the clinic. Following the accumulated findings of IL-1β's central modulatory role in the immune system and the implication of inflammatory pathways in cancer, the use of IL-1β antagonists was first proposed and then also pursued for oncology disorders. However, this approach has consistently relied on the perceived need of interfering with IL-1β …

Viroporin Activity Is Necessary For Intercellular Calcium Signals That Contribute To Viral Pathogenesis, J Thomas Gebert, Francesca J Scribano, Kristen A Engevik, Ethan M Huleatt, Michael R Eledge, Lauren E Dorn, Asha A Philip, Takahiro Kawagishi, Harry B Greenberg, John T Patton, Joseph M Hyser

Faculty, Staff and Students Publications

Viruses engage in a variety of processes to subvert host defenses and create an environment amenable to replication. Here, using rotavirus as a prototype, we show that calcium conductance out of the endoplasmic reticulum by the virus encoded ion channel, NSP4, induces intercellular calcium waves that extend beyond the infected cell and contribute to pathogenesis. Viruses that lack the ability to induce this signaling show diminished viral shedding and attenuated disease in a mouse model of rotavirus diarrhea. This implicates nonstructural protein 4 (NSP4) as a virulence factor and provides mechanistic insight into its mode of action. Critically, this …

Nkapl Facilitates Transcription Pause-Release And Bridges Elongation To Initiation During Meiosis Exit, Zhenlong Kang, Chen Xu, Shuai Lu, Jie Gong, Ruoyu Yan, Gan Luo, Yuanyuan Wang, Qing He, Yifei Wu, Yitong Yan, Baomei Qian, Shenglin Han, Zhiwen Bu, Jinwen Zhang, Xian Xia, Liang Chen, Zhibin Hu, Mingyan Lin, Zheng Sun, Yayun Gu, Lan Ye

Transcription elongation, especially RNA polymerase II (Pol II) pause-release, is less studied than transcription initiation in regulating gene expression during meiosis. It is also unclear how transcription elongation interplays with transcription initiation. Here, we show that depletion of NKAPL, a testis-specific protein distantly related to RNA splicing factors, causes male infertility in mice by blocking the meiotic exit and downregulating haploid genes. NKAPL binds to promoter-associated nascent transcripts and co-localizes with DNA-RNA hybrid R-loop structures at GAA-rich loci to enhance R-loop formation and facilitate Pol II pause-release. NKAPL depletion prolongs Pol II pauses and stalls the SOX30/HDAC3 transcription initiation complex …

Investigating The Role Of The Nsp15 Amino-Terminal Domain In Nsp15 Function, Viral Replication, And Pathogenesis, Monika Evdokimova

Dissertations

Identifying conserved mechanisms used by viruses to delay host innate responses can reveal potential targets for antiviral therapeutics. Here, we investigated coronavirus nonstructural protein 15 (nsp15), which encodes a highly conserved endoribonuclease (EndoU). EndoU functions as an immune antagonist by limiting the accumulation of viral replication intermediates that would otherwise be sensed by the host. Despite being a promising antiviral target, it has been difficult to develop small molecule inhibitors that target the EndoU active site. We generated nsp15 mutants of SARS-CoV-2 and mouse coronavirus MHV-A59 and identified conserved residues within the amino-terminal domain that are required for EndoU activity. …

Revisiting Phosphoregulation Of Cdc25c During M-Phase Induction, Tan Tan, Chuanfen Wu, Ruoning Wang, Bih-Fang Pan, David Hawke, Fumin Yin, Zehao Su, Boye Liu, Sue-Hwa Lin, Wei Zhang, Jian Kuang

Faculty, Staff and Student Publications

Cdc25C undergoes a sudden and substantial gel mobility shift at M-phase onset, correlating with abrupt activation of both Cdc25C and Cdk1 activities. A positive feedback loop between Cdk1 and Cdc25C has been used to explain this hallmark phenomenon. Here, we demonstrate that the M-phase supershift and robust activation of Cdc25C are due to the site-comprehensive phosphorylation of its long intrinsically disordered regulatory domain without requiring Cdk1 or other major mitotic kinase activities. The phosphorylation process involves substrate-mediated assembly of phosphorylation machinery that catalyzes multisite phosphorylation continuously without substrate dissociation. In contrast to the site-comprehensive phosphorylation of Cdc25C occurring at M-phase …

Innervation Of Human Intestinal Organoids, Rachel C Bordelon, Madushani Herath, Allison L Speer

Faculty, Staff and Student Publications

The complexity of intestinal cytoarchitecture and function poses significant challenges for the creation of the bioengineered small intestine. Techniques for generating human intestinal organoids (HIOs) resembling human small intestine have been previously reported. HIOs contain epithelium and mesenchyme but lack other critical components of functional intestine such as the enteric nervous system (ENS), immune cells, vasculature, and microbiome. Two independent research groups have published distinct methods to innervate HIOs with an ENS. Here we discuss a unique method of incorporating the ENS into an HIO-derived bioengineered small intestine, which utilizes components of these prior reports to optimize progenitor cell identity …

Arthritis leads to bone erosion due to an imbalance between osteoclast and osteoblast function. Our prior investigations revealed that the Ca2+-selective ion channel, Orai1, is critical for osteoclast maturation. Here, we show that the small-molecule ELP-004 preferentially inhibits transient receptor potential canonical (TRPC) channels. While ELP-004 minimally affected physiological RANKL-induced osteoclast maturation in murine bone marrow- and spleen-derived myeloid cells (BMSMCs) and human PBMC-derived cells, it potently interfered with osteoclast maturation driven by TNFα or LTB4. The contribution of TRPC channels to osteoclastogenesis was examined using BMSMCs derived from TRPC4-/- or TRPC(1-7)-/- mice, again revealing preferential interference with osteoclastogenesis driven …

Peritoneal carcinomatosis (PC) in gastric adenocarcinoma (GAC) is the most common metastatic site and leads to a short median survival. Exosomes have been shown to remodel the microenvironment, facilitating tumor metastases. However, the functional component in GAC cell-derived exosomes that remodel the landscape in the peritoneal cavity remains unclear. To address this, we performed in-depth proteomic profiling of ascites-derived exosomes from patients with PC, and we found that Galectin-3 was highly enriched in exosomes derived from malignant ascites. exosomal Galectin-3 was the crucial regulator of PC. Blockage of exosomal Galectin-3 significantly inhibited tumor metastases and prolonged overall survival. Exosomal Galectin-3 …

Colorectal cancer (CRC) is the third most common cancer worldwide, with rising prevalence among younger adults. Several lifestyle factors, particularly disruptions in circadian rhythms by light-dark (LD) shifts, are known to increase CRC risk. Epidemiological studies previously showed LD-shifts are associated with increased risk of CRC. To explore the mechanisms and interactions between LD-shift and intestinal aging, we investigated how the combination of LD-shifts and aging impacts colon carcinogenesis development. Our data showed that LD-shifts and aging increased colon tumorigenesis. Notably, LD-shift accelerated intestinal aging by altering aging-related pathways, such as intestinal barrier damage, accompanied by dysbiotic changes in the …

Barcoded Sars-Cov-2 Viruses Define The Impact Of Duration And Route Of Exposure On The Transmission Bottleneck In A Hamster Model, Reed Trende, Tamarand L Darling, Tianyu Gan, David Wang, Adrianus C M Boon

2020-Current year OA Pubs

The transmission bottleneck, defined as the number of viruses shed from one host to infect another, is an important determinant of the rate of virus evolution and the level of immunity required to protect against virus transmission. Despite its importance, the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) transmission bottleneck remains poorly characterized. We adapted a SARS-CoV-2 reverse genetics system to generate a pool of >200 isogenic SARS-CoV-2 viruses harboring specific 6-nucleotide barcodes, infected donor hamsters with this pool, and exposed contact hamsters to paired infected donors, varying the duration and route of exposure. Following exposure, the nasal turbinates, trachea, …

Dunbar’S Number In Motion: Agent-Based Simulations Of Friendship Formation, Christopher R. Cooke, Cameron D. Lutz

Northeast Journal of Complex Systems (NEJCS)

By contrasting Lévy flight and random walk strategies in simulated agents, we discern the effect of movement behavior on the total duration of social interactions. Our agent-based simulation results approximate empirically observed Dunbar social circle formation using simple behavioral rules of interaction and compatibility to mimic exogenous attribute-based friendship formation. We simulate the complexities of social interactions among agents with unique attributes and a time budget for social engagement over a one-year period. Two distinct simulations were conducted to evaluate the behavioral contributions of Lévy flight and random walk movement patterns on cumulative interaction duration and the formation of Dunbar …
