Intracellular Fate Of Bovine Milk Exosomes In Murine Bone Marrow-Derived Macrophages, Afsana Khanam, Janos Zempleni

Department of Nutrition and Health Sciences: Faculty Publications

Milk exosomes (MEs) and their microRNA cargos constitute novel bioactive food compounds, and bovine MEs (BMEs) are being considered for use in drug delivery. The internalization of MEs by macrophages and degradation in lysosomes (in all cells) limit biological activities. Here, we determined whether BMEs internalized by murine bone marrow-derived macrophages (BMDMs) retrofuse with the intralumenal membrane in the multivesicular body (MVB) for subsequent release into the extracellular space or whether BMEs are destined for degradation in lysosomes.

Conclusions: The retrofusion of BME-derived intralumenal MVBs and secretion of BME into the extracellular space is quantitatively minor in BMDMs. The majority …

Mechanical Overload-Induced Muscle-Derived Extracellular Vesicles Promote Adipose Tissue Lipolysis, Ivan J. Vechetti Jr, Bailey D. Peck, Yuan Wen, R Grace Walton, Taylor R. Valentino, Alexander P. Alimov, Cory M. Dungan, Douglas W. Van Pelt, Ferdinand Von Walden, Bjorn Alkner, Charlotte A. Peterson, John J. Mccarthy

Department of Nutrition and Health Sciences: Faculty Publications

How regular physical activity is able to improve health remains poorly understood. The release of factors from skeletal muscle following exercise has been proposed as a possible mechanism mediating such systemic benefits. We describe a mechanism wherein skeletal muscle, in response to a hypertrophic stimulus induced by mechanical overload (MOV), released extracellular vesicles (EVs) containing muscle-specific miR-1 that were preferentially taken up by epidydimal white adipose tissue (eWAT). In eWAT, miR-1 promoted adrenergic signaling and lipolysis by targeting Tfap2α, a known repressor of Adrβ3 expression. Inhibiting EV release prevented the MOV-induced increase in eWAT miR-1 abundance and expression of …

Management Of Late Summer Planted Annual Forages For Grazing And The Impacts Of Novel Sweet Bran Plus Products On Performance And Carcass Characteristics Of Beef Finishing Steers, Devin Anthony Jakub

Department of Animal Science: Dissertations, Theses, and Student Research

Two separate grazing studies were conducted to evaluate: 1) the effects of rapeseed inclusion into late summer planted oats on the performance of growing steers during late fall and winter (Exp. 1) and 2) the effects of forage allocation on forage utilization and performance of steers grazing a late summer planted oat-rapeseed mix (Exp. 2). Variation in the corn wet milling process can result in negative effects on animal performance, nonetheless, there remains interest in further exploration and refinement of corn wet milling byproducts to achieve optimal byproduct compositions and cattle performance. Thus, another experiment was conducted to evaluate the …

Evidence Of Myomir Regulation Of The Pentose Phosphate Pathway During Mechanical Load-Induced Hypertrophy, Taylor Valentino, Vandre C. Figueiredo, C. Brooks Mobley, John J. Mccarthy, Ivan Jose Vechetti Jr

Department of Nutrition and Health Sciences: Faculty Publications

Many of the molecular and cellular mechanisms discovered to regulate skeletal muscle hypertrophy were first identified using the rodent synergist ablation model. This model reveals the intrinsic capability and necessary pathways of skeletal muscle growth in response to mechanical overload (MOV). Reminiscent of the rapid cellular growth observed with cancer, we hypothesized that in response to MOV, skeletal muscle would undergo metabolic programming to sustain increased demands to support hypertrophy. To test this hypothesis, we analyzed the gene expression of specific metabolic pathways taken from transcriptomic microarray data of a MOV time course. We found an upregulation of genes involved …

Department of Nutrition and Health Sciences: Faculty Publications

Aberrant activation of the nucleotide-binding domain and leucine-rich repeat related (NLR) family, pyrin domain containing 3 (NLRP3) inflammasome drives the development of many complex inflammatory diseases, such as obesity, Alzheimer’s disease, and atherosclerosis. However, no medications specifically targeting the NLRP3 inflammasome have become clinically available. Therefore, we aim to identify new inhibitors of the NLRP3 inflammasome in this study. Methods: Vesicle-like nanoparticles (VLNs) were extracted from garlic chives and other Allium vegetables and their effects on the NLRP3 inflammasome were evaluated in primary macrophages. After garlic chive-derived VLNs (GC-VLNs) were found to exhibit potent anti-NLRP3 inflammasome activity in cell culture, …

Department of Nutrition and Health Sciences: Faculty Publications

We sought to characterize the lipid profile of skeletal muscle cell-derived Extracellular Vesicles (EVs) to determine if a hypertrophic stimulus would affect the lipid composition of C2C12 myotube-derived EVs. Analyses included C2C12 murine myoblasts differentiated into myotubes and treated with Insulin-Like Growth Factor 1 (IGF-1) for 24 h to induce hypertrophic growth. EVs were isolated from cell culture media, quantified using Nanoparticle Tracking Analysis (NTA) and analyzed using Transmission Electron Microscopy (TEM). EVs were homogenized and lipids extracted for quantification by Mass Spectrometry followed by downstream lipid class enrichment and lipid chain analysis. IGF-1 treatment elicited an increase in CD63 …

Weight Status Perceptions And Food Choice, Christopher R. Gustafson

Cornhusker Economics

Does your weight status—whether your height and weight put you into the normal weight, overweight, or obese category—predict your food choices, or even the types of food you’ll pay attention to when making a choice? What about the weight status you perceive yourself to be? These are important questions because the percentage of the population that is overweight or obese in the U.S.—and world-wide—has been increasing for decades despite a wide range of efforts aimed at slowing/reversing its growth. In the U.S., over 70 percent of the population is overweight or obese. High body weight has numerous consequences for individuals …

Sars-Cov-2 Concentrations In A Wastewater Collection System Indicated Potential Covid-19 Hotspots At The Zip Code Level, Renys E. Barrios, Chin Lim, Megan S. Kelley, Xu Li

Department of Nutrition and Health Sciences: Faculty Publications

Wastewater based epidemiology (WBE) has been successfully applied for SARS-CoV-2 surveillance at the city and building levels. However, sampling at the city level does not provide sufficient spatial granularity to identify COVID-19 hotspots, while data from building-level sampling are too narrow in scope for broader public health application. The objective of this study was to examine the feasibility of using wastewater from wastewater collection systems (WCSs) to monitor COVID-19 hotspots at the zip code level. In this study, 24-hr composite wastewater samples were collected from five manholes and two wastewater treatment plants (WWTPs) in the City of Lincoln, Nebraska. By …

Bovine Mammary Alveolar Mac-T Cells Afford A Tool For Studies Of Bovine Milk Exosomes In Drug Delivery, Mojisola Ogunnaike

Department of Nutrition and Health Sciences: Dissertations, Theses, and Student Research

Bovine milk exosomes (BMEs) have attracted attention as vehicles for delivering RNA therapeutics. BMEs originate in mammary alveolar cells. Here, we determined whether bovine mammary alveolar MAC-T cells are a promising tool to assess RNA delivery by BMEs. MAC-T cells exosomes (MAC-T BMEs) and BMEs were harvested by differential ultracentrifugation. Exosome size, morphology, microRNA content and marker proteins were assessed using nanoparticle tracking analysis, transmission electron microscopy, real-time PCR and immunoblot analysis, respectively. MAC-T cells were genetically engineered to secrete MAC-T BMEs endogenously labeled with a near-infrared fluorescent protein and tissue distribution was compared to fluorophore-labeled BMEs following intravenous injection …

Ruminant Milk-Derived Extracellular Vesicles: A Nutritional And Therapeutic Opportunity?, Siew Ling Ong, Cherie Blenkiron, Stephen Haines, Alejandra Acevedo-Fani, Juliana A.S. Leite, Janos Zempleni, Rachel C. Anderson, Mark J. Mccann

Department of Nutrition and Health Sciences: Faculty Publications

Milk has been shown to contain a specific fraction of extracellular particles that are reported to resist digestion and are purposefully packaged with lipids, proteins, and nucleic acids to exert specific biological effects. These findings suggest that these particles may have a role in the quality of infant nutrition, particularly in the early phase of life when many of the foundations of an infant’s potential for health and overall wellness are established. However, much of the current research focuses on human or cow milk only, and there is a knowledge gap in how milk from other species, which may be …

Protective Role Of Palmitoleate Against Zika Virus-Induced Apoptosis In Placental Trophoblasts, Philma Glora Muthuraj

College of Education and Human Sciences: Dissertations, Theses, and Student Research

Zika virus (ZIKV) infection in pregnant women causes congenital Zika syndrome which involves birth defects such as intrauterine growth restriction (IUGR), retinal defects and microcephaly in the fetus. ZIKV infection results in placental pathology which plays a crucial role in disease transmission from mother to fetus. Currently, there is no Food and Drug Administration (FDA) approved vaccine or therapeutic drug against ZIKV. In this thesis, we have elucidated the cell signaling pathways connected to ZIKV-induced apoptosis in trophoblasts and also the protective effect of palmitoleate against ZIKV-induced apoptosis. First, we demonstrated the molecular mechanism behind ZIKV-induced apoptosis using an in …

Zika virus (ZIKV) infection in pregnancy is associated with the development of microcephaly, intrauterine growth restriction, and ocular damage in the fetus. ZIKV infection of the placenta plays a crucial role in the vertical transmission from the maternal circulation to the fetus. Our previous study suggested that ZIKV induces endoplasmic reticulum (ER) stress and apoptosis of placental trophoblasts. Here, we showed that palmitoleate, an omega-7 monounsaturated fatty acid, prevents ZIKV-induced ER stress and apoptosis in placental trophoblasts. Human trophoblast cell lines (JEG-3 and JAR) and normal immortalized trophoblasts (HTR-8) were used. We observed that ZIKV infection of the trophoblasts resulted …

Peterson

Department of Nutrition and Health Sciences: Faculty Publications

Using in vivo muscle stem cell (satellite cell)-specific extracellular vesicle (EV) tracking, satellite cell depletion, in vitro cell culture, and single-cell RNA sequencing, we show satellite cells communicate with other cells in skeletal muscle during mechanical overload. Early satellite cell EV communication primes the muscle milieu for proper long-term extracellular matrix (ECM) deposition and is sufficient to support sustained hypertrophy in adult mice, even in the absence of fusion to muscle fibers. Satellite cells modulate chemokine gene expression across cell types within the first few days of loading, and EV delivery of miR 206 to fibrogenic cells represses Wisp1 expression …

Saturated Free Fatty Acids Induce Placental Trophoblast Lipoapoptosis, Sathish Kumar Natarajan, Taylor Bruett, Philma Glora Muthuraj, Prakash K. Sahoo, Jillian Power, Justin L. Mott, Corrine Hanson, Ann Anderson-Berry

Department of Nutrition and Health Sciences: Faculty Publications

Obesity during pregnancy increases the risk for maternal complications like gestational diabetes, preeclampsia, and maternal inflammation. Maternal obesity also increases the risk of childhood obesity, intrauterine growth restriction (IUGR) and diabetes to the offspring. Increased circulating free fatty acids (FFAs) in obesity due to adipose tissue lipolysis induces lipoapoptosis to hepatocytes, cholangiocytes, and pancreatic-β-cells. During the third trimester of human pregnancy, there is an increase in maternal lipolysis and release of FFAs into the circulation. It is currently unknown if increased FFAs during gestation as a result of maternal obesity cause placental cell lipoapoptosis. Increased exposure of FFAs during maternal …
