Proteolytic activation of the hemagglutinin (HA) glycoprotein by host cellular proteases is pivotal for influenza A virus (IAV) infectivity. Highly pathogenic avian influenza viruses possess the multibasic cleavage site of the HA which is cleaved by ubiquitous proteases, such as furin; in contrast, the monobasic HA motif is recognized and activated by trypsin-like proteases, such as the transmembrane serine protease 2 (TMPRSS2). Here, we aimed to determine the effects of TMPRSS2 on the replication of pandemic H1N1 and H3N2 subtype IAVs in the natural host, the pig. The use of the CRISPR/Cas 9 system led to the establishment of homozygous …

Gram-negative bacterial bloodstream infections (GNB-BSI) are common and frequently lethal. Despite appropriate antibiotic treatment, relapse of GNB-BSI with the same bacterial strain is common and associated with poor clinical outcomes and high healthcare costs. The role of persister cells, which are sub-populations of bacteria that survive for prolonged periods in the presence of bactericidal antibiotics, in relapse of GNB-BSI is unclear. Using a cohort of patients with relapsed GNB-BSI, we aimed to determine how the pathogen evolves within the patient between the initial and subsequent episodes of GNB-BSI and how these changes impact persistence.

The Respiratory Enzyme Complex Rnf Is Vital For Metabolic Adaptation And Virulence In Fusobacterium Nucleatum, Timmie A Britton, Chenggang Wu, Yi-Wei Chen, Dana Franklin, Yimin Chen, Truc T Luong, Hung Ton-That

Faculty, Staff and Student Publications

The Gram-negative oral pathobiont Fusobacterium nucleatum can traverse to extra-oral sites such as placenta and colon, promoting adverse pregnancy outcomes and colorectal cancer, respectively. How this anaerobe sustains many metabolically changing environments enabling its virulence potential remains unclear. Informed by our genome-wide transposon mutagenesis, we report here that the highly conserved Rhodobacter nitrogen-fixation (Rnf) complex, encoded by the rnfCDGEAB gene cluster, is key to fusobacterial metabolic adaptation and virulence. Genetic disruption of the Rnf complex via non-polar, in-frame deletion of rnfC (ΔrnfC) abrogates polymicrobial interaction (or coaggregation) associated with adhesin RadD and biofilm formation. The defect in coaggregation …

Exploring The Spiritual Alliance Of Maintaining A 5-Acre Tropical Farm Through The Lens Of Occupational Engagement, Jose Rafols, Amy Wagenfeld

The Open Journal of Occupational Therapy

Large-scale commercial farmers and small scale “hobby” farmers engage in growing crops for subsistence and survival for themselves, their families, communities, and beyond. Their reverence and passion for farming make them good stewards of both community and world population nourishment. We suggest there may be a collective physical, emotional, and spiritual draw to farming that is interwoven with occupational engagement. Through a personal narrative approach, we reflect on the meaning and the work-focused occupation of farming and specifically how spirituality may be a guiding force that supports engagement despite seemingly insurmountable environmental and personal hardships. With an increasing interest in …

Increased Iron Uptake By Splenic Hematopoietic Stem Cells Promotes Tet2-Dependent Erythroid Regeneration, Yu-Jung Tseng, Yuki Kageyama, Rebecca L Murdaugh, Ayumi Kitano, Jong Hwan Kim, Jonathan Tiessen, Hidetaka Uryu, Koichi Takahashi, James F Martin, Md Abul Hassan Samee, Daisuke Nakada

Faculty, Staff and Student Publications

Hematopoietic stem cells (HSCs) are capable of regenerating the blood system, but the instructive cues that direct HSCs to regenerate particular lineages lost to the injury remain elusive. Here, we show that iron is increasingly taken up by HSCs during anemia and induces erythroid gene expression and regeneration in a Tet2-dependent manner. Lineage tracing of HSCs reveals that HSCs respond to hemolytic anemia by increasing erythroid output. The number of HSCs in the spleen, but not bone marrow, increases upon anemia and these HSCs exhibit enhanced proliferation, erythroid differentiation, iron uptake, and TET2 protein expression. Increased iron in HSCs promotes …

We aimed to evaluate the health impact and cost-effectiveness of introducing different HPV vaccines into immunization programs and scaling up the screening program in Guangdong. We used a dynamic compartmental model to estimate the impact of intervention strategies during 2023-2100. We implemented the incremental cost-effectiveness ratio (ICER) in costs per averted disability-adjusted life year (DALY) as an indicator to assess the effectiveness of the intervention. We used an age-standardized incidence of 4 cases per 100,000 women as the threshold for the elimination of cervical cancer. Compared …

Armc5 Controls The Degradation Of Most Pol Ii Subunits, And Armc5 Mutation Increases Neural Tube Defect Risks In Mice And Humans, Xiao He, Isabelle Bourdeau, Wei Shi, Lucia Gagliardi, Maria Candida Barisson Villares Fragoso, Junzheng Peng, Jiangping Wu

Faculty, Staff and Student Publications

BACKGROUND: Neural tube defects (NTDs) are caused by genetic and environmental factors. ARMC5 is part of a novel ubiquitin ligase specific for POLR2A, the largest subunit of RNA polymerase II (Pol II).

RESULTS: We find that ARMC5 knockout mice have increased incidence of NTDs, such as spina bifida and exencephaly. Surprisingly, the absence of ARMC5 causes the accumulation of not only POLR2A but also most of the other 11 Pol II subunits, indicating that the degradation of the whole Pol II complex is compromised. The enlarged Pol II pool does not lead to generalized Pol II stalling or a generalized …

Engagement For Life's Sake: Reflections On Partnering And Partnership With Rural Tribal Nations, Chelsea Schelly, Valoree Gagnon, Kathleen Brosemer, Kristin Arola

Michigan Tech Publications

In this paper, we reflect on our collective experiences engaging with Anishinaabe Tribal Nations in the Great Lakes region to support Tribal sovereignty in decision-making for food, energy, and water (FEW) systems. In these diverse experiences, we find common lessons. The first set of lessons contributes new empirical knowledge regarding the challenges and opportunities that rural Great Lakes Tribal Nations navigate for enacting sovereignty in decision-making. Our experiences illustrate that while Tribal Nations benefit from a broad and deep commitment to sovereignty and many cultural strengths, they are often challenged by shortages in administrative capacity; technical support; and embeddedness in …

The Antagonist Effect Of Pichia Kluyveri Against The Aflatoxigenic Aspergillus Flavus, Wafa Masoud

Journal of the Arab American University مجلة الجامعة العربية الامريكية للبحوث

Aspergillus flavus is one of the main fungi that are known to produce Aflatoxin B1 (AFB1). AFB1 has been detected in many food products and reported to be a carcinogenic. Using a biocontrol agent against A. flavus can safely eliminate or reduce the occurrence of AFB1 in food. Therefore, the effects of four yeast strains of Pichia kluyveri on the growth and spore germination of A. flavus were studied. In addition, the effect of exposure of A. flavus to the yeast’s headspace, as well as the effects of different headspace concentrations of 2-phenyl ethyl acetate and ethyl acetate, on the …

Trade-Offs In Rooting Strategy Dimensions Along An Edaphic Gradient In A Grassland Ecosystem, Yuguo Yang, Sabrina E. Russo

School of Biological Sciences: Faculty Publications

1. Roots are essential to the diversity and functioning of plant communities, but trade-offs in rooting strategies are still poorly understood.
2. We evaluated existing frameworks of rooting strategy trade-offs and tested their underlying assumptions, guided by the hypothesis that community-level rooting strategies are best described by a combination of variation in organ-level traits, plant-level root:shoot allocation and symbiosis-level mycorrhizal dependency. We tested this hypothesis using data on plant community structure, above-and below-ground biomass, eight root traits including mycorrhizal colonisation and soil properties from an edaphic gradient driven by elevation and water availability in sandhills prairie, Nebraska, USA.
3. We found multidimensional trade-offs …

The Ecological Responses To Hydroperiod Of Wetland Plant Species Determined By Manipulated Soil Surface Elevation (Marsh Organs), Brandon Wolff

LSU Master's Theses

As sea level rise, subsidence, and abandonment of natural deltaic processes due to a highly engineered Mississippi River continue to threaten Louisiana’s coastal wetlands, the need for a system-wide understanding of natural wetland land-building and preservation processes has never been greater. A key component of any wetland is the ever-changing water environment that periodically floods and dries the marsh platforms. The flooding depth, duration, and frequency, known as the hydroperiod, along with salinity and soil fertility are key determining factors of vegetation and marsh types at a particular location. Different types of vegetation will have different growth characteristics such as …

Regulation Of Polysaccharide In Wu-Tou Decoction On Intestinal Microflora And Pharmacokinetics Of Small Molecular Compounds In Aia Rats, Zhiqiang Liu, Fei Zheng, Yulin Dai, Zifeng Pi, Hao Yue

Faculty, Staff and Student Publications

Wu-tou decoction (WTD), a traditional Chinese medicine prescription, is used to treat rheumatoid arthritis (RA). It works by controlling intestinal flora and its metabolites, which in turn modulates the inflammatory response and intestinal barrier function. Small molecular compounds (SM) and polysaccharides (PS) were the primary constituents of WTD extract. In this work, a model of adjuvant-induced arthritis (AIA) in rats was established and treated with WTD, SM, and PS, respectively. 16S rRNA gene sequencing was used to examine the regulatory impact of the various groups on the disturbance of the gut flora induced by RA. Further, since PS cannot be …

A Test Of The Pioneer Factor Hypothesis For Silent Gene Activation, Jeffrey Hansen

Arts & Sciences Graduate Student Theses and Dissertations

Transcription factors (TFs) activate silent genes by binding to and opening heterochromatic instances of their motifs. While we rely on this process for cellular reprogramming, we have an incomplete understanding of which TFs are capable of recognizing inaccessible instance of their motifs and what parameters are important for this activity. My thesis work aimed to address these two questions. The leading model for silent gene activation is the pioneer factor hypothesis (PFH). The PFH states that pioneer factors (PFs) are qualitatively unique TFs that can bind to and open DNA and subsequently recruit non-pioneer factors (nonPFs) to activate expression. We …

Akt Enhances The Vulnerability Of Cancer Cells To Vcp/P97 Inhibition-Mediated Paraptosis, Dong Min Lee, In Young Kim, Hong Jae Lee, Min Ji Seo, Mi-Young Cho, Gyesoon Yoon, Seok Soon Park, Seong-Yun Jeong, Eun Kyung Choi, Yong Hyeon Choi, Chae-Ok Yun, Mirae Yeo, Eunhee Kim, Kyeong Sook Choi

Faculty, Staff and Student Publications

Valosin-containing protein (VCP)/p97, an AAA+ ATPase critical for maintaining proteostasis, emerges as a promising target for cancer therapy. This study reveals that targeting VCP selectively eliminates breast cancer cells while sparing non-transformed cells by inducing paraptosis, a non-apoptotic cell death mechanism characterized by endoplasmic reticulum and mitochondria dilation. Intriguingly, oncogenic HRas sensitizes non-transformed cells to VCP inhibition-mediated paraptosis. The susceptibility of cancer cells to VCP inhibition is attributed to the non-attenuation and recovery of protein synthesis under proteotoxic stress. Mechanistically, mTORC2/Akt activation and eIF3d-dependent translation contribute to translational rebound and amplification of proteotoxic stress. Furthermore, the ATF4/DDIT4 axis augments VCP …
