Comprehensive Sumo Proteomic Analyses Identify Hiv Latency-Associated Proteins In Microglia., Fergan Imbert, Dianne Langford Feb 2025

Comprehensive Sumo Proteomic Analyses Identify Hiv Latency-Associated Proteins In Microglia., Fergan Imbert, Dianne Langford

Rowan-Virtua School of Osteopathic Medicine Departmental Research

SUMOylation, the post-translational modification of proteins by small ubiquitin-like modifiers, plays a critical role in regulating various cellular processes, including innate immunity. This modification is essential for modulating immune responses and influencing signaling pathways that govern the activation and function of immune cells. Recent studies suggest that SUMOylation also contributes to the pathophysiology of central nervous system (CNS) viral infections, where it contributes to the host response and viral replication dynamics. Here, we explore the multifaceted role of SUMOylation in innate immune signaling and its implications for viral infections within the CNS. Notably, we present novel proteomic analyses aimed at …

All Current Publications

This second of four fact sheets in this series explores materials needed to start seeds indoors—specifically, seeds, containers, soilless mix (potting soil), lights, water, fertilizer, a heat source, fans, labels, and a general growing space. Our focus is mainly starting vegetables. However, the principles discussed apply to starting herbs and other ornamental annuals and perennials. Online propagation protocols, books on plant propagation, and other Utah State University (USU) Extension resources discuss how to start other unique and less common plants.


Oncogenic Kras Mutations Confer A Unique Mechanotransduction Response To Peristalsis In Colorectal Cancer Cells, Abigail J Clevenger, Claudia A Collier, John Paul M Gorley, Sarah Colijn, Maygan K Mcfarlin, Spencer C Solberg, Scott Kopetz, Amber N Stratman, Shreya A Raghavan Feb 2025

Oncogenic Kras Mutations Confer A Unique Mechanotransduction Response To Peristalsis In Colorectal Cancer Cells, Abigail J Clevenger, Claudia A Collier, John Paul M Gorley, Sarah Colijn, Maygan K Mcfarlin, Spencer C Solberg, Scott Kopetz, Amber N Stratman, Shreya A Raghavan

Faculty, Staff and Student Publications

Colorectal cancer tumors start as polyps on the inner lining of the colorectum, in which they are exposed to the mechanics of peristalsis. Our previous work leveraged a custom-built peristalsis bioreactor to demonstrate that colonic peristalsis led to cancer stem cell enrichment in colorectal cancer cells. However, this malignant mechanotransductive response was confined to select colorectal cancer lines that harbored an oncogenic mutation in the Kirsten rat sarcoma virus (KRAS) gene. In this study, we explored the involvement of activating KRAS mutations on peristalsis-associated mechanotransduction in colorectal cancer. Peristalsis enriched cancer stem cell marker Leucine-rich repeat-containing G protein-coupled receptor 5 …

Brd7 Loss Reawakens Dormant Metastasis Initiating Cells In Lung By Forging An Immunosuppressive Niche, Jayanta Mondal, Junfeng Zhang, Feng Qing, Shunping Li, Dhiraj Kumar, Jason T Huse, Filippo G Giancotti

Faculty, Staff and Student Publications

Metastasis in cancer is influenced by epigenetic factors. Using an in vivo screen, we demonstrate that several subunits of the polybromo-associated BAF (PBAF) chromatin remodeling complex, particularly Brd7, are required for maintaining breast cancer metastatic dormancy in the lungs of female mice. Brd7 loss induces metastatic reawakening, along with modifications in epigenomic landscapes and upregulated oncogenic signaling. Breast cancer cells harboring Brd7 inactivation also reprogram the surrounding immune microenvironment by downregulating MHC-1 expression and promoting a pro-metastatic cytokine profile. Flow cytometric and single-cell analyses reveal increased levels of pro-tumorigenic inflammatory and transitional neutrophils, CD8+ exhausted T cells, and CD4+ stress …

Ion suppression is a major problem in mass spectrometry (MS)-based metabolomics; it can dramatically decrease measurement accuracy, precision, and sensitivity. Here we report a method, the IROA TruQuant Workflow, that uses a stable isotope-labeled internal standard (IROA-IS) library plus companion algorithms to: 1) measure and correct for ion suppression, and 2) perform Dual MSTUS normalization of MS metabolomic data. We evaluate the method across ion chromatography (IC), hydrophilic interaction liquid chromatography (HILIC), and reversed-phase liquid chromatography (RPLC)-MS systems in both positive and negative ionization modes, with clean and unclean ion sources, and across different biological matrices. Across the broad range …

For most researchers, academic publishing serves two goals that are often misaligned-knowledge dissemination and establishing scientific credentials. While both goals can encourage research with significant depth and scope, the latter can also pressure scholars to maximize publication metrics. Commercial publishing companies have capitalized on the centrality of publishing to the scientific enterprises of knowledge dissemination and academic recognition to extract large profits from academia by leveraging unpaid services from reviewers, creating financial barriers to research dissemination, and imposing substantial fees for open access. We present a set of perspectives exploring alternative models for communicating and disseminating scientific research. Acknowledging that …

Exercise and Sport Studies: Faculty Publications

The menopausal transition is associated with increased risk for cardiovascular disease (CVD). Hot flashes (HF), a cardinal symptom of menopause, have been associated with increased CVD risk, particularly in perimenopausal women. Flow-mediated dilation (FMD) is an indicator of endothelial function and a subclinical CVD risk factor. Lower FMD has been associated with more HF. As moderate to vigorous physical activity (MVPA) is recognized to reduce CVD risk, our goal was to determine whether higher levels of MVPA change the relationship between HF and FMD in perimenopausal women. Healthy perimenopausal women had HF measured objectively using sternal skin conductance for 24 …

Lytic transglycosylases (LTs) are bacterial enzymes involved in biosynthesis and maintenance of the peptidoglycan cell wall. LTs are reported to be regulated by two paralogs of Inhibitor of Vertebrate Lysozymes: Ivyp1 and Ivyp2. This study investigated the regulatory dynamics between the soluble LT (SltB1), and Ivy paralogs as putative regulators in Pseudomonas aeruginosa (PA). The secondary objective was to delineate the critical roles played by a glutamic acid at position 135 in SltB1 and a histidine at position 62 in Ivyp1 in governing their molecular interaction through site directed mutagenesis. Isolated SltB1 shows no lytic activity in our assay, in …

Bladder cancer (BLCA) genomic profiling has identified molecular subtypes with distinct clinical characteristics and variable sensitivities to frontline therapy. BLCAs can be categorized into luminal or basal subtypes based on their gene expression. We comprehensively characterized nine human BLCA cell lines (UC3, UC6, UC9, UC13, UC14, T24, SCaBER, RT4V6 and RT112) into molecular subtypes using orthotopic xenograft models. Patient-derived, luciferase-tagged BLCA cell lines were cultured in vitro and engrafted into bladders of NSG mice. Tumor growth was monitored using bioluminescence imaging and mRNA-based molecular classification was used to characterize xenografts into molecular subtypes. RNAseq analysis and basal, luminal, and epithelial-mesenchymal …

Test Of Strategies For Production And Harvest Of Edible Roots From Hydroponic Plants, Mariam Yaslem Albreiki Feb 2025

Test Of Strategies For Production And Harvest Of Edible Roots From Hydroponic Plants, Mariam Yaslem Albreiki

Theses

Hydroponic plant cultivation is becoming increasingly popular in the UAE, especially for leafy greens and fruit vegetables. By the end of the growing cycle, the roots of hydroponic plants are usually treated as crop residues, even though roots of several species are potentially edible and could be processed into food or nutraceuticals. Root crops like sweet potato or carrot might even be grown in hydroponic systems for the primary purpose of producing edible fibrous or tuberous roots. However, the use of hydroponic systems for the production of root biomass is not yet common, and most farmers strive to produce plants …

Background: Coronary artery disease is the most common form of cardiovascular disease. It is caused by excess plaque along the arterial wall, blocking blood flow to the heart (stenosis). A percutaneous coronary intervention widens the arterial wall with the inflation of a balloon inside the lesion area and leaves behind a metal stent to prevent re-narrowing of the artery (restenosis). However, in-stent restenosis may occur due to damage to the arterial wall tissue, triggering neointimal hyperplasia, producing fibrotic and calcified plaques and narrowing the artery again. Drug-eluting stents, which slowly release medication to inhibit neointimal hyperplasia, are used to prevent …

A 62-year-old man was referred to our hospital presenting with a sore throat, dyspnea, and cervical swelling. Initial precontrast CT scans revealed a cervical and mediastinal hematoma, along with a hemothorax. Further dynamic contrast-enhanced CT scans indicated contrast media extravasation dorsal to the right thyroid gland lobe, suggesting a rupture of the right inferior thyroid artery or a parathyroid adenoma. Following endotracheal intubation, angiography confirmed extravasation from the right inferior thyroid artery. Transarterial embolization (TAE) was successfully performed using a gelatin sponge. The cervical and mediastinal hematoma were surgically excised, and the right inferior parathyroid gland was simultaneously resected. Pathological …

Hydrolysis Of The Acetyl-Coa Allosteric Activator By Staphylococcus Aureus Pyruvate Carboxylase, Amanda J. Laseke, Jeremy R. Lohman, Martin St. Maurice

Biological Sciences Faculty Research and Publications

Pyruvate carboxylase (PC) catalyzes the carboxylation of pyruvate to oxaloacetate which serves as an important anaplerotic reaction to replenish citric acid cycle intermediates. In most organisms, the PC-catalyzed reaction is allosterically activated by acetyl-coenzyme A. It has previously been reported that vertebrate PC can catalyze the hydrolysis of acetyl-CoA, offering a potential means for the enzyme to attenuate its allosteric activation. However, in the years since this initial report, there has been no further investigation of this phenomenon. The allosteric binding site for acetyl-CoA is now well characterized, enabling more detailed studies on acetyl-CoA hydrolysis at the allosteric site. Here, …

Constructing A Parameterized Stimuli Space Suitable To Induce Controlled Changes In Human And Machine Perceptual Systems, Andrew Frankel

Dissertations, Theses, and Capstone Projects

Traditional computer vision applications focus on objective tasks, such as object detection, classification, or segmentation. Much of human experience is inherently subjective, such as our personal response to artwork. Individualized experiences are challenging to replicate in a controlled laboratory environment, as those experiences depend on the unique history and internal models of the observer. This work presents a technique to construct a 2-dimensional parameterized stimuli space suitable to induce controlled changes in the perceptual systems of both human and machine observers. Our contributions are threefold:

Bacterial chondronecrosis with osteomyelitis (BCO) is caused by Salmonella, Staphylococcus spp., Escherichia coli, Enterococcus spp., and Mycoplasma spp. It is a leading cause of broiler lameness, resulting in economic losses and welfare concerns. BCO occurs when bacteria enter the bloodstream and colonize bone tissue. It is exacerbated by rapid growth, mechanical stress (e.g., repetitive pressure on hock joints and footpads), uneven flooring, or excessive body weight in commercial settings. This study tested the effectiveness of a probiotic program and an inactivated vaccine in reducing BCO lameness. The probiotic program included an Enterococcus faecium spray at hatch and a triple-strain Bacillus-based …

Stable understory microclimates within undisturbed rainforests are often considered refugia against climate change. However, this assumption contrasts with emerging evidence of Neotropical bird population declines in intact rainforests. We assessed the vulnerability of resident rainforest birds to climatic variability, focusing on dry season severity characterized by hotter temperatures and reduced rainfall. Analyzing 4264 individual bird captures over 27 years, we found that harsher Amazonian dry seasons significantly reduced apparent survival for 24 of 29 species, with longer-lived species being more strongly affected. Our model predicted that a 1°C increase in average dry season temperature would reduce the mean apparent survival …

Background/Objectives: Interferon gamma (IFN-γ) in the melanoma tumor microenvironment plays opposing roles, orchestrating both pro-tumorigenic activity and anticancer immune responses. Our previous studies demonstrated the role of neuronal nitric oxide synthase (nNOS) in IFN-γ-stimulated melanoma progression. However, the underlying mechanism has not been well defined. This study determined whether the nNOS/NO and COX-2/PGE2 signaling pathways crosstalk and augment the pro-tumorigenic effects of IFN-γ in melanoma. Methods: Bioinformatic analysis of patient and cellular proteomic data was conducted to identify proteins of interest associated with IFN-γ treatment in melanoma. Changes in protein expression were determined using various analytical techniques including …

Some of the most pronounced effects of climate change on agricultural output include the depletion of freshwater resources and heightened salinization of arable land, especially in arid and semi-arid regions, adversely affecting crop yields. Many economic vegetable crops including members of the brassica family are sensitive to salt-stress. The use of organic soil amendments such as biochar and compost as complimentary nutrient sources in the sandponics system can improve the performance of crops. The study aimed to evaluate the effect of organic amendment on the growth performance and yield of broccoli and Nile tilapia (Oreochromis niloticus) under brackish …
