Investigating Clot-Flow Interactions By Integrating Intravital Imaging With In Silico Modeling For Analysis Of Flow, Transport, And Hemodynamic Forces, Chayut Teeraratkul, Maurizio Tomaiuolo, Timothy Stalker, Debanjan Mukherjee

Cardeza Foundation for Hematologic Research

As a blood clot forms, grows, deforms, and embolizes following a vascular injury, local clot-flow interactions lead to a highly dynamic flow environment. The local flow influences transport of biochemical species relevant for clotting, and determines the forces on the clot that in turn lead to clot deformation and embolization. Despite this central role, quantitative characterization of this dynamic clot-flow interaction and flow environment in the clot neighborhood remains a major challenge. Here, we propose an approach that integrates dynamic intravital imaging with computer geometric modeling and computational flow and transport modeling to develop a unified in silico framework to …

Can Vpac-Targeted Cu-67-Tp3805 Play A Theranostic Role For Prostate Cancer?: A Quest, Mathew L. Thakur

Department of Radiology Faculty Papers

Early and accurate detection of prostate cancer (PCa) together with effective treatment can save lives. Despite the recent advances in its treatment, the mortality trends due to PCa, in the USA, continue to be alarming with annual increase of 3%. In this brief communication, we propose a novel approach to treat PCa, its metastasis and recurrence. This is guided by a large quantity of preliminary data driven by targeting an endogenous genetic product, VPAC, expressed in high density on the cell surface at the onset of genetic mutation that ignites the cancerous transformation. A large body of preclinical and clinical …

Mechanism Of Anion Exchange And Small-Molecule Inhibition Of Pendrin, Lie Wang, Anthony Hoang, Eva Gil-Iturbe, Arthur Laganowsky, Matthias Quick, Ming Zhou

Faculty, Staff and Students Publications

Pendrin (SLC26A4) is an anion exchanger that mediates bicarbonate (HCO3−) exchange for chloride (Cl−) and is crucial for maintaining pH and salt homeostasis in the kidney, lung, and cochlea. Pendrin also exports iodide (I−) in the thyroid gland. Pendrin mutations in humans lead to Pendred syndrome, causing hearing loss and goiter. Inhibition of pendrin is a validated approach for attenuating airway hyperresponsiveness in asthma and for treating hypertension. However, the mechanism of anion exchange and its inhibition by drugs remains poorly understood. We applied cryo-electron microscopy to determine structures of pendrin from Sus scrofa in the presence of either Cl−, …

Comparison Of Energy Budget Of Cockroach Nymph (Hemimetabolous) And Hornworm (Holometabolous) Under Food Restriction, Charles J Green, Chen Hou

Faculty, Staff and Student Publications

Animals with different life histories budget their intake energy differently when food availability is low. It has been shown previously that hornworm (larva of Manduca sexta), a holometabolous insect species with a short development stage, prioritizes growth at the price of metabolism under food restriction, but it is unclear how hemimetabolous insect species with a relatively long development period budget their intake energy under food scarcity. Here, we use orange head cockroaches (Eublaberus posticus) to investigate this question. We found that for both species under food restriction, rates of metabolism and growth were suppressed, but the degree …

Thermus thermophilus bacteriophage P23-45 encodes a giant 5,002-residue tail tape measure protein (TMP) that defines the length of its extraordinarily long tail. Here, we show that the N-terminal portion of P23-45 TMP is an unusual RNA polymerase (RNAP) homologous to cellular RNAPs. The TMP-fused virion RNAP transcribes pre-early phage genes, including a gene that encodes another, non-virion RNAP, that transcribes early and some middle phage genes. We report the crystal structures of both P23-45 RNAPs. The non-virion RNAP has a crab-claw-like architecture. By contrast, the virion RNAP adopts a unique flat structure without a clamp. Structure and sequence comparisons of …

Emerging Perspectives Of Synaptic Biomarkers In Als And Ftd, Karthik Krishnamurthy, Raj Kumar Pradhan

Farber Institute for Neuroscience Staff Papers and Presentations

Amyotrophic Lateral Sclerosis (ALS) and Frontotemporal Dementia (FTD) are debilitating neurodegenerative diseases with shared pathological features like transactive response DNA-binding protein of 43 kDa (TDP-43) inclusions and genetic mutations. Both diseases involve synaptic dysfunction, contributing to their clinical features. Synaptic biomarkers, representing proteins associated with synaptic function or structure, offer insights into disease mechanisms, progression, and treatment responses. These biomarkers can detect disease early, track its progression, and evaluate therapeutic efficacy. ALS is characterized by elevated neurofilament light chain (NfL) levels in cerebrospinal fluid (CSF) and blood, correlating with disease progression. TDP-43 is another key ALS biomarker, its mislocalization linked …

Through Their Eyes: Illuminating The Nature Of Animal Use In Conservation Research Through An Analysis Of Peer-Reviewed Literature In The Journal Conservation Biology, Sarah Hollmann

Theses and Dissertations

Non-human animals habitually have been treated as a resource in the service of humans and human-driven values. The field of conservation is not immune to this fact. But, because conservation is seemingly dedicated to the saving and protection of species and nature, until recently the field historically has been given a pass for the use and treatment of animals that are done “in the name of conservation”. This treatment is evident in common conservation practices such as capture, captivity, invasive sampling, aversive treatment, experimental manipulation, and intentional killing. A principal question we are asking is how individual animals are impacted …

Secreted Igm Modulates Il-10 Expression In B Cells, Shannon Mcgettigan, Lazaro Aira, Gaurav Kumar, Romain Ballet, Eugene Butcher, Nicole Baumgarth, Gudrun Debes

Department of Microbiology and Immunology Faculty Papers

IL-10⁺ B cells are critical for immune homeostasis and restraining immune responses in infection, cancer, and inflammation; however, the signals that govern IL-10⁺ B cell differentiation are ill-defined. Here we find that IL-10⁺ B cells expand in mice lacking secreted IgM ((s)IgM^–/–) up to 10-fold relative to wildtype (WT) among all major B cell and regulatory B cell subsets. The IL-10⁺ B cell increase is polyclonal and presents within 24 hours of birth. In WT mice, sIgM is produced prenatally and limits the expansion of IL-10⁺ B cells. Lack of the high affinity …

Justice Bork, Or, Be Careful Which Supreme Court Nominees You Choose To Fight, Mikel Norris

Political Science

This study uses counterfactual analysis to assess whether a hypothetical Supreme Court with Robert Bork as a member would have decided cases differently than the actual Supreme Court.

I utilize both a qualitative analysis, and a quantitative Bayesian counterfactual model to predict Supreme Court case outcomes from 1988 to 2012.

The results show that several salient cases would have been decided differently, most of the decisions decided over the time frame would have remained unchanged. I also find that a hypothetical Supreme Court with Robert Bork as an associate justice would not have radically shifted rightward. Rather, the results show …

Advancing Cell Segmentation Methods Through An Innovative Technique And Systematic Evaluation, Yuxing Wang

Theses

In the biomedical field, downstream cell-level analysis is a crucial step for comprehensively characterizing cells' location, function, morphology, and phenotype, relying on the accurate identification of individual cells. Consequently, there is increasing interest in the high quality of identified cell boundaries for biologists or researchers. Currently, cell segmentation methods are categorized into two types: Image-based and RNA-based cell segmentation. However, these methods face significant challenges. For example, most image-based methods tend to identify cell nuclear boundaries rather than entire cell boundaries when only nuclear staining images are available, and their performance is affected by noise in images and training labels. …

Current And Future Therapeutic Strategies For High-Grade Gliomas Leveraging The Interplay Between Epigenetic Regulators And Kinase Signaling Networks, Lea M Stitzlein, Jack T Adams, Erin N Stitzlein, Richard W Dudley, Joya Chandra

Faculty, Staff and Student Publications

Targeted therapies, including small molecule inhibitors directed against aberrant kinase signaling and chromatin regulators, are emerging treatment options for high-grade gliomas (HGG). However, when translating these inhibitors into the clinic, their efficacy is generally limited to partial and transient responses. Recent studies in models of high-grade gliomas reveal a convergence of epigenetic regulators and kinase signaling networks that often cooperate to promote malignant properties and drug resistance. This review examines the interplay between five well-characterized groups of chromatin regulators, including the histone deacetylase (HDAC) family, bromodomain and extraterminal (BET)-containing proteins, protein arginine methyltransferase (PRMT) family, Enhancer of zeste homolog 2 …

Sirtuin 2 Inhibition Modulates Chromatin Landscapes Genome-Wide To Induce Senescence In Atrx-Deficient Malignant Glioma, Prit Benny Malgulwar, Carla Danussi, Sharvari Dharmaiah, William Johnson, Anand Singh, Kunal Rai, Arvind Rao, Jason T Huse

Faculty, Staff and Student Publications

BACKGROUND: Functional inactivation of ATRX characterizes large subgroups of malignant gliomas in adults and children. ATRX deficiency in glioma induces widespread chromatin remodeling, driving transcriptional shifts and oncogenic phenotypes. Effective strategies to therapeutically target these broad epigenomic sequelae remain undeveloped.

METHODS: We utilized integrated multiomics and the Broad Institute Connectivity Map (CMAP) to identify drug candidates that could potentially revert ATRX-deficient transcriptional changes. We then employed disease-relevant experimental models to evaluate functional phenotypes, coupling these studies with epigenomic profiling to elucidate molecular mechanism(s).

RESULTS: CMAP analysis and transcriptional/epigenomic profiling implicated the Class III HDAC Sirtuin2 (SIRT2) as a central mediator …

Glycosylphosphatidylinositols (GPIs) anchor over 150 proteins as GPI-anchored proteins (GPI-APs) with crucial roles in diverse biological processes. The highly conserved biosynthesis of GPI-APs involves precise steps with at least 21 genes, categorized as PIG and PGAP genes. Pathogenic variants in these genes are linked to human diseases, highlighting the importance of each biosynthesis step. PGAP2 stands out among these genes due to its association with an expanded clinical spectrum of neurodevelopmental disorder (NDD) phenotypes with biallelic pathogenic variants. We present four patients from two families, one consanguineous and the other nonconsanguineous, each displaying distinct clinical presentations, including intellectual disability, hyperphosphatasia, …

Vibroscape Analysis Reveals Acoustic Niche Overlap And Plastic Alteration Of Vibratory Courtship Signals In Ground-Dwelling Wolf Spiders, Noori Choi, Pat Miller, Eileen A. Hebets

School of Biological Sciences: Faculty Publications

To expand the scope of soundscape ecology to encompass substrate-borne vibrations (i.e. vibroscapes), we analyzed the vibroscape of a deciduous forest floor using contact microphone arrays followed by automated processing of large audio datasets. We then focused on vibratory signaling of ground-dwelling Schizocosa wolf spiders to test for (i) acoustic niche partitioning and (ii) plastic behavioral responses that might reduce the risk of signal interference from substrate-borne noise and conspecific/heterospecific signaling. Two closely related species - S. stridulans and S. uetzi - showed high acoustic niche overlap across space, time, and dominant frequency. Both species show plastic behavioral …

A High-Protein Diet Promotes Atrial Arrhythmogenesis Via Absent-In-Melanoma 2 Inflammasome, Jia Song, Jiao Wu, Dexter J Robichaux, Tingting Li, Shuyue Wang, Maria J Arredondo Sancristobal, Bingning Dong, Dobromir Dobrev, Jason Karch, Sandhya S Thomas, Na Li

Faculty, Staff and Students Publications

High-protein diets (HPDs) offer health benefits, such as weight management and improved metabolic profiles. The effects of HPD on cardiac arrhythmogenesis remain unclear. Atrial fibrillation (AF), the most common arrhythmia, is associated with inflammasome activation. The role of the Absent-in-Melanoma 2 (AIM2) inflammasome in AF pathogenesis remains unexplored. In this study, we discovered that HPD increased susceptibility to AF. To demonstrate the involvement of AIM2 signaling in the pathogenesis of HPD-induced AF, wildtype (WT) and Aim2^−/− mice were fed normal-chow (NC) and HPD, respectively. Four weeks later, inflammasome activity was upregulated in the atria of WT-HPD mice, but not …
