Phase Separation Clustering Of Poly Ubiquitin Cargos On Ternary Mixture Lipid Membranes By Synthetically Cross-Linked Ubiquitin Binder Peptides, Soojung Kim, Kamsy K. Okafor, Rina Tabuchi, Cedric Briones, Il Hyung Lee

Department of Chemistry and Biochemistry Faculty Scholarship and Creative Works

Ubiquitylation is involved in various physiological processes, such as signaling and vesicle trafficking, whereas ubiquitin (UB) is considered an important clinical target. The polymeric addition of UB enables cargo molecules to be recognized specifically by multivalent binding interactions with UB-binding proteins, which results in various downstream processes. Recently, protein condensate formation by ubiquitylated proteins has been reported in many independent UB processes, suggesting its potential role in governing the spatial organization of ubiquitylated cargo proteins. We created modular polymeric UB binding motifs and polymeric UB cargos by synthetic bioconjugation and protein purification. Giant unilamellar vesicles with lipid raft composition were …

Responding To Digital Addiction, Ned Snow

Seattle University Law Review

In Unwired: Gaining Control over Addictive Technologies, Professor Gaia Bernstein calls our attention to the growing problem of digital addiction. Digital addiction may sound like something out of a science-fiction novel or something that does not raise the same sort of real-life practical concerns as are present in a physical health crisis or an economic decline. But as Bernstein presents the evidence, we learn that the consequences of digital addiction can be just as harmful as a serious disease or a financial depression. Cognitive development disorders, anxiety, emotional depression, social isolation, and other mental health ills can be debilitating—as much …

2020-Current year OA Pubs

BACKGROUND: Thrombosis in modified Blalock-Taussig-Thomas shunts (mBTTS) poses a life-threatening risk for infants with shunt-dependent congenital heart disease. Although hemodynamics influence thrombosis, the specific geometric contributors remain unclear. This study aimed to identify key variables to inform future hemodynamic analysis, hypothesizing that brachiocephalic, subclavian artery, mBTTS, and/or pulmonary artery (PA) geometry play a critical role in clot formation.

METHODS AND RESULTS: We retrospectively analyzed 11 infants with hypoplastic left heart syndrome who underwent mBTTS placement. Using computed tomography and magnetic resonance imaging, we generated 3-dimensional models of the shunt and surrounding vasculature. Geometric variables related to shunt positioning and vascular …

The Autophagy Protein Atg14 Safeguards Against Unscheduled Pyroptosis Activation To Enable Embryo Transport During Early Pregnancy, Pooja Popli, Arin K Oestreich, Vineet K Maurya, Marina N Rowen, Yong Zhang, Michael J Holtzman, Ramya Masand, John P Lydon, Shizuo Akira, Kelle Moley, Ramakrishna Kommagani

2020-Current year OA Pubs

Recurrent pregnancy loss, characterized by two or more failed clinical pregnancies, poses a significant challenge to reproductive health. In addition to embryo quality and endometrial function, proper oviduct function is also essential for successful pregnancy establishment. Therefore, structural abnormalities or inflammation resulting from infection in the oviduct may impede the transport of embryos to the endometrium, thereby increasing the risk of miscarriage. However, our understanding of the biological processes that preserve the oviductal cellular structure and functional integrity is limited. Here, we report that autophagy-related protein ATG14 plays a crucial role in maintaining the cellular integrity of the oviduct by …

Mistargeted Retinal Axons Induce A Synaptically Independent Subcircuit In The Visual Thalamus Of Albino Mice, Sean Mccracken, Liam Mccoy, Ziyi Hu, Julie A Hodges, Katia Valkova, Philip R Williams, Josh L Morgan

2020-Current year OA Pubs

In albino mice and EphB1 knockout mice, mistargeted retinal ganglion cell axons form dense islands of axon terminals in the dorsal lateral geniculate nuclei (dLGN). The formation of these islands of retinal input depends on developmental patterns of spontaneous retinal activity. We reconstructed the microcircuitry of the activity-dependent islands and found that the boundaries of the island represent a remarkably strong segregation within retinogeniculate connectivity. We conclude that when sets of retinal input are established in the wrong part of the dLGN, the developing circuitry responds by forming a synaptically isolated subcircuit within the otherwise fully connected network. The fact …

Dietary Effects On The Retina Of Hamsters, Nicole El-Darzi, Natalia Mast, Yong Li, Irina A. Pikuleva

Faculty Scholarship

The retina is a sensory tissue in the back of the eye, which captures visual information and relays it to the brain. The retinal pigment epithelium separates the neural retina from the choroidal (systemic) circulation and is thereby exposed to circulating lipoprotein particles. Herein, we used hamsters and conducted various retinal evaluations of animals fed either a normal diet or a Western-type diet (WTD). Prior to evaluations, hamsters were injected with indocyanine green (ICG), a fluorescent dye that binds to various proteins and lipids in the systemic circulation. The WTD increased plasma levels of total and HDL cholesterol 1.8- and …

Novel Method For Pure Polymer Vagus Nerve Stimulators, James Dodge Iii

ENGS 88 Honors Thesis (AB Students)

Vagus nerve stimulation (VNS) has become a promising treatment for epilepsy, depression, obesity, and more. However, the state-of-the-art nerve cuffs use metal conductors, limiting the implanted VNS devices’ biocompatibility, electronic properties, and ultimately the device lifetime. Because the benefits of VNS treatment increase over time, and metal limits the lifetime of devices, a transition to non-metallic conductors with a better match to tissue material properties and safer electronic properties promises to increase the lifetime of VNS devices. To demonstrate the replacement of metal with a conductor with properties closer to that of body tissue, a novel fabrication scheme was designed …

An Exploration Of The Experiences Of Perinatal Depression And Anxiety Among Pregnant And Parenting Adolescents In The Tampa Bay Area Of Florida, Olajumoke Adetoun Ojeleye

USF Tampa Graduate Theses and Dissertations

Perinatal depression (PND) and perinatal anxiety (PNA) are increasing among pregnant and parenting adolescents (PPAs), with PNA often underrecognized. This leads to significant socioeconomic costs and adverse maternal consequences if untreated. Hence, this dissertation explores the experiences of PND and PNA among PPAs, focusing on their knowledge gaps, perception, mental health needs, care preferences, and access to PMH care. The research employs a qualitative design (free-listing and in-depth interviews) to gather participant insights. Key findings reveal that many PPAs possess limited knowledge about PNA when compared to PND. Lack of support from partners, family, and peers emerged as the topmost …

No Evidence Of Fisheries-Induced Evolution Observed From Bluegill Populations In Small Kansas Impoundments, Morganne C. Borsh, Ben C. Neely, Peter B. Berendzen

Faculty Publications

Objective: Bluegill Lepomis macrochirus support recreational fisheries throughout much of their geographic distribution. One characteristic of the species is for males to exhibit alternative reproductive tactics to maximize production of progeny. These divergent strategies coupled with size-selective harvest by anglers create the potential for fisheries-induced evolution (FIE). As such, we sought to characterize genetic diversity of five fished and five unfished Bluegill populations to test for the occurrence of FIE. Methods: Fin clips from 100 Bluegill across 10 populations in southeast Kansas were collected to examine genetic diversity and test for the occurrence of FIE associated with long-term selective harvest. …

Icos-Expressing Car-T Cells Mediate Durable Eradication Of Triple-Negative Breast Cancer And Metastasis, Shelley Herbrich, Mehdi Chaib, Padmanee Sharma

Faculty, Staff and Student Publications

Triple-negative breast cancer (TNBC) remains one of the most aggressive and therapeutically challenging breast cancer subtypes. In their recent study, Cao et al introduced a B7H3-specific chimeric antigen receptor (CAR)-T cell with constitutive inducible co-stimulator (ICOS) expression (ICOS-B7H3-CAR-T), which demonstrated eradication of TNBC, including metastases, in preclinical models. These CAR-T cells exploit the expression of ICOS ligand on TNBC cells, enhancing antitumor cytotoxicity through ICOS signaling. Compared with conventional B7H3-CAR-T cells, the ICOS-B7H3-CAR-T cells exhibited superior antitumor efficacy, increased cytokine secretion, and prolonged survival in xenograft murine models. This study highlights ICOS as a promising co-stimulatory molecule for improving CAR-T …
