The impacts of science are felt across all socio-ecological levels, ranging from the individual to societal. In order to adapt or respond to scientific discoveries, novel technologies, or biomedical or environmental challenges, a fundamental understanding of science is necessary. However, antiscientific rhetoric, mistrust in science, and the dissemination of misinformation hinder the promotion of science as a necessary and beneficial component of our world. Scientists can promote scientific literacy by establishing dialogues with nonexperts, but they may find a lack of formal training as a barrier to public engagement. To address this, the American Society for Biochemistry and Molecular Biology …

Phylogeographic History Of The Leaf-Eared Mouse, Phyllotis Xanthopygus Complex, Tabitha R. Mcfarland

Biology ETDs

Museum collections provide essential biodiversity sampling needed to understand the species limits, phylogeny, and biogeographic history of mammals, all key features of the foundation for comparative analyses in ecology and evolution. We add to this framework a diverse assemblage of species of leaf-eared mice (genus Phyllotis) in South America and then focus on the Phyllotis xanthopygus complex by combining available mitochondrial sequence (cytochrome b; cytb) data (351 GenBank samples) with 52 newly sequenced museum samples from the northern extent of this complex’s range (51 from Bolivia and 1 from northern Chile) to reconstruct evolutionary relationships using maximum …

Very little is known about the physiological role of nicotinic receptors in canine bladders, although functional nicotinic receptors have been reported in bladders of many species. Utilizing in vitro methods, we evaluated nicotinic receptors mediating bladder function in dogs: control (9 female and 11 male normal controls, 5 sham operated), Decentralized (9 females, decentralized 6–21 mo), and obturator-to-pelvic nerve transfer reinnervated (ObNT-Reinn; 9 females; decentralized 9–13 mo, then reinnervated with 8–12 mo recovery). Muscle strips were collected, mucosa-denuded, and mounted in muscle baths before incubation with neurotransmitter antagonists, and contractions to the nicotinic receptor agonist epibatidine were determined. Strip response …

A Polycistronic System For Multiplexed And Precalibrated Expression Of Multigene Pathways In Fungi, Qun Yue, Jie Meng, Yue Qiu, Miaomiao Yin, Liwen Zhang, Weiping Zhou, Zhiqiang An, Zihe Liu, Qipeng Yuan, Wentao Sun, Chun Li, Huimin Zhao, István Molnár, Yuquan Xu, Shuobo Shi

Faculty, Staff and Student Publications

Synthetic biology requires efficient systems that support the well-coordinated co-expression of multiple genes. Here, we discover a 9-bp nucleotide sequence that enables efficient polycistronic gene expression in yeasts and filamentous fungi. Coupling polycistronic expression to multiplexed, markerless, CRISPR/Cas9-based genome editing, we develop a strategy termed HACKing (Highly efficient and Accessible system by CracKing genes into the genome) for the assembly of multigene pathways. HACKing allows the expression level of each enzyme to be precalibrated by linking their translation to those of host proteins with predetermined abundances under the desired fermentation conditions. We validate HACKing by rapidly constructing highly efficient Saccharomyces …

Diastrophic dysplasia (DTD) is a recessive chondrodysplasia caused by pathogenic variants in the SLC26A2 gene encoding for a cell membrane sulfate/chloride antiporter crucial for sulfate uptake and glycosaminoglycan (GAG) sulfation. Research on a DTD animal model has suggested possible pharmacological treatment approaches. In view of future clinical trials, the identification of non-invasive biomarkers is crucial to assess the efficacy of treatments. Urinary GAG composition has been analyzed in several metabolic disorders including mucopolysaccharidoses. Moreover, the N-terminal fragment of collagen X, known as collagen X marker (CXM), is considered a real-time marker of endochondral ossification and growth velocity and was studied …

Michigan Tech Publications

A variety of environmental issues are affecting crops all across the world, but rising temperatures are posing the greatest threat. High temperature has been found to drastically inhibit seedling emergence and cause leaf necrosis at the seedling stage, which results in poor plant stand and significantly decreased yields. Polyamines (PAs) are positively charged, low-molecular-weight aliphatic nitrogenous bases present in all living organisms and are involved in various biological processes in plant growth and development, including senescence and response to different abiotic stresses. Putrescine (Put) functions as a master growth regulator that promotes optimal plant development and greater stress tolerance. Here, …

Comparing Four Indices Of Physiological Stress In An Urban-Adapted Songbird Between Urban And Rural Habitats, Rachel Kaplan

Master of Science in Integrative Biology Theses

Birds show tremendous variation in the extent to which different species tolerate life in urban habitats, yet it remains unclear why some species thrive while others cannot. My work explores possible phenotypes that make an urban-adapted species, the European starling (Sturnus vulgaris), so successful in both rural and urban areas. Literature on stress-urbanization relationship remains highly equivocal partly due to an array of different study systems being compared as well as to key methodological differences. The present study quantified metrics of both acute stress (i.e., stress-induced corticosterone and breath rate) and chronic stress (i.e., baseline corticosterone and total …

Measuring Bee Effects On Seed Traits Of Hybrid Sunflower, Gary J. Brewer, Kentaro Miwa, Kathy Hanford

Department of Entomology: Faculty Publications

In hybrid sunflower, bee pollination can improve productivity, but the contribution of bees to productivity may be over or underestimated. To estimate bee effects (seed trait gains from exposure to bees during anthesis), single capitula are commonly covered with a porous material to exclude bees. However, depending on the exclosure porosity, estimates of the magnitude of bee effects will vary. In two studies, porosity size and bee effect gains in two sunflower types were tested. In the exclosure study, Delnet exclosures severely reduced seed set and exclosures with larger porosities and had smaller and similar effects. However, since a few …

Human Patient-Derived Brain Tumor Models To Recapitulate Ependymoma Tumor Vasculature., Min D Tang-Schomer, Markus J Bookland, Jack E Sargent, Taylor N Jackvony

Faculty Research 2023

Despite in vivo malignancy, ependymoma lacks cell culture models, thus limiting therapy development. Here, we used a tunable three-dimensional (3D) culture system to approximate the ependymoma microenvironment for recapitulating a patient's tumor in vitro. Our data showed that the inclusion of VEGF in serum-free, mixed neural and endothelial cell culture media supported the in vitro growth of all four ependymoma patient samples. The growth was driven by Nestin and Ki67 double-positive cells in a putative cancer stem cell niche, which was manifested as rosette-looking clusters in 2D and spheroids in 3D. The effects of extracellular matrix (ECM) such as collagen …

Carbamoylated Erythropoietin-Induced Cerebral Blood Perfusion And Vascular Gene Regulation., Jayanarayanan Sadanandan, Monica Sathyanesan, Yutong Liu, Neeraj K Tiwari, Samuel S Newton

Faculty Research 2023

Cerebral hypoperfusion is associated with enhanced cognitive decline and increased risk of neuropsychiatric disorders. Erythropoietin (EPO) is a neurotrophic factor known to improve cognitive function in preclinical and clinical studies of neurodegenerative and psychiatric disorders. However, the clinical application of EPO is limited due to its erythropoietic activity that can adversely elevate hematocrit in non-anemic populations. Carbamoylated erythropoietin (CEPO), a chemically engineered non-erythropoietic derivative of EPO, does not alter hematocrit and maintains neurotrophic and behavioral effects comparable to EPO. Our study aimed to investigate the role of CEPO in cerebral hemodynamics. Magnetic resonance imaging (MRI) analysis indicated increased blood perfusion …

Loss Of Pml Nuclear Bodies In Familial Amyotrophic Lateral Sclerosis-Frontotemporal Dementia, Francesco Antoniani, Marco Cimino, Laura Mediani, Jonathan Vinet, Enza M. Verde, Valentina Secco, Alfred Yamoah, Priyanka Tripathi, Eleonora Aronica, Maria Elena Cicardi, Davide Trotti, Jared Sterneckert, Anand Goswami, Serena Carra

Farber Institute for Neuroscience Faculty Papers

Amyotrophic Lateral Sclerosis (ALS) and Frontotemporal Dementia (FTD) are two neurodegenerative disorders that share genetic causes and pathogenic mechanisms. The critical genetic players of ALS and FTD are the TARDBP, FUS and C9orf72 genes, whose protein products, TDP-43, FUS and the C9orf72-dipeptide repeat proteins, accumulate in form of cytoplasmic inclusions. The majority of the studies focus on the understanding of how cells control TDP-43 and FUS aggregation in the cytoplasm, overlooking how dysfunctions occurring at the nuclear level may influence the maintenance of protein solubility outside of the nucleus. However, protein quality control (PQC) systems that maintain protein homeostasis comprise …

A World Of Difference: The Fundamental Opposition Between Transhumanist “Welfarism” And Disability Advocacy, Susan B. Levin

Philosophy: Faculty Publications

From the standpoint of disability advocacy, further exploration of the concept of well-being stands to be availing. The notion that “welfarism” about disability, which Julian Savulescu and Guy Kahane debuted, qualifies as helpful is encouraged by their claim that welfarism shares important commitments with that advocacy. As becomes clear when they apply their welfarist frame to procreative decisions, endorsing welfarism would, in fact, sharply undermine it. Savulescu and Kahane's Principle of Procreative Beneficence—which reflects transhumanism, or advocacy of radical bioenhancement—morally requires parents to choose the child who will, in all probability, have “the best life.” Assuming the emergence of potent …

Diabetes is one of the leading causes of death and disability worldwide, and affects people regardless of country, age group, or sex. Using the most recent evidentiary and analytical framework from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD), we produced location-specific, age-specific, and sex-specific estimates of diabetes prevalence and burden from 1990 to 2021, the proportion of type 1 and type 2 diabetes in 2021, the proportion of the type 2 diabetes burden attributable to selected risk factors, and projections of diabetes prevalence through 2050.

Methods

Estimates of diabetes prevalence and burden were computed in …

Deletion Of Taf1 And Taf5 In Zebrafish Capitulate Cardiac And Craniofacial Abnormalities Associated With Tafopathies Through Perturbations In Metabolism, Jamison Leid, Ryan Gray, Peter Rakita, Andrew L Koenig, Rohan Tripathy, James A J Fitzpatrick, Charles Kaufman, Lilianna Solnica-Krezel, Kory J Lavine

2020-Current year OA Pubs

Intellectual disability is a neurodevelopmental disorder that affects 2-3% of the general population. Syndromic forms of intellectual disability frequently have a genetic basis and are often accompanied by additional developmental anomalies. Pathogenic variants in components of TATA-binding protein associated factors (TAFs) have recently been identified in a subset of patients with intellectual disability, craniofacial hypoplasia, and congenital heart disease. This syndrome has been termed as a TAFopathy and includes mutations in TATA binding protein (TBP), TAF1, TAF2, and TAF6. The underlying mechanism by which TAFopathies give rise to neurodevelopmental, craniofacial, and cardiac abnormalities remains to be defined. Through a forward …

The Cerebellum Contributes To Generalized Seizures By Altering Activity In The Ventral Posteromedial Nucleus, Jaclyn Beckinghausen, Joshua Ortiz-Guzman, Tao Lin, Benjamin Bachman, Luis E Salazar Leon, Yu Liu, Detlef H Heck, Benjamin R Arenkiel, Roy V Sillitoe

Duncan NRI Faculty and Staff Publications

Thalamo-cortical networks are central to seizures, yet it is unclear how these circuits initiate seizures. We test whether a facial region of the thalamus, the ventral posteromedial nucleus (VPM), is a source of generalized, convulsive motor seizures and if convergent VPM input drives the behavior. To address this question, we devise an in vivo optogenetic mouse model to elicit convulsive motor seizures by driving these inputs and perform single-unit recordings during awake, convulsive seizures to define the local activity of thalamic neurons before, during, and after seizure onset. We find dynamic activity with biphasic properties, raising the possibility that heterogenous …

Lower Urinary Tract Symptoms In Depression: A Review, Danyon J. Anderson, Alise Aucoin, Colton R. Toups, Devin Cormier, Matthew Mcdonald, Jamal Hasoon, Omar Viswanath, Alan D. Kaye, Ivan Urits

School of Medicine Faculty Publications

Lower Urinary Tract Symptoms (LUTS) are frequently present in the general population as patients age with approximately a third of individuals experiencing LUTS during their lifetime. LUTS can be further defined as having any of the following symptoms: urinary hesitancy, straining, nocturia, increased urination frequency, and dysuria. LUTS has the potential for patients to contribute their symptoms to what can normally occur as we age. This can lead to a decrease in patients seeking care and could negatively impact patients’ health-related quality of life (HRQL). In conjunction with LUTS, we obtained from our analysis that LUTS and depression are closely …

COVID-19 affects brain function, as deduced by the "brain fog" that is often encountered in COVID-19 patients and some cognitive impairment that is observed in many a patient in the post-COVID-19 period. Approximately one-third of patients, even when they have recovered from the acute somatic disease, continue to show posttraumatic stress disorder (PTSD) symptoms. We hypothesized that the persistent changes induced by COVID-19 on brain structure would overlap with those associated with PTSD. We performed a thorough PubMed search on 25 April 2023 using the following strategy: ((posttraumatic OR PTSD) AND COVID-19 AND (neuroimaging OR voxel OR VBM OR freesurfer …

Genomically-informed therapy requires consideration of the functional impact of genomic alterations on protein expression and/or function. However, a substantial number of variants are of unknown significance (VUS). The MD Anderson Precision Oncology Decision Support (PODS) team developed an actionability classification scheme that categorizes VUS as either "Unknown" or "Potentially" actionable based on their location within functional domains and/or proximity to known oncogenic variants. We then compared PODS VUS actionability classification with results from a functional genomics platform consisting of mutant generation and cell viability assays. 106 (24%) of 438 VUS in 20 actionable genes were classified as oncogenic in functional …
