Defrnd: Detergent-Free Reconstitution Into Native Nanodiscs With Designer Membrane Scaffold Peptides, Qian Ren, Vinay Idikuda, Baron Chanda, Et Al.

2020-Current year OA Pubs

Membrane scaffold protein-based nanodiscs have facilitated unprecedented structural and biophysical analysis of membrane proteins in a near-native lipid environment. However, successful reconstitution of membrane proteins in nanodiscs requires prior solubilization and purification in detergents, which may impact their physiological structure and function. Furthermore, the detergent-mediated reconstitution of nanodiscs is unlikely to recapitulate the precise composition or asymmetry of native membranes. To circumvent this fundamental limitation of traditional nanodisc technology, we herein describe the development of membrane-solubilizing peptides to directly extract membrane proteins from native cell membranes into nanoscale discoids. By systematically protein engineering and screening, we create a class of …

Patients with relapsed/refractory (R/R) B-cell acute lymphoblastic leukemia (B-ALL) with central nervous system (CNS) involvement (CNS B-ALL) have poor outcomes and were frequently excluded from CD19-targeting chimeric antigen receptor (CAR) T-cell clinical trials. The efficacy and safety of brexucabtagene autoleucel (brexu-cel) in adults with R/R B-ALL was established by the ZUMA-3 trial, which excluded patients with advanced or symptomatic CNS involvement. In this retrospective multicenter analysis, we investigated the safety and efficacy of brexu-cel in patients with CNS B-ALL using data from the ROCCA (Real-World Outcomes Collaborative for CAR T in ALL) consortium. Of 189 patients who received infusion, 31 …

Abstract

Medication Safety: A Policy Journey to Reduce Medication Errors

Background: Medication errors have long been a significant concern. Unsafe medication practices and errors can pose serious risks of injury and preventable harm within healthcare systems.

These errors can lead to severe consequences and have the potential to result in injury, disability, or even death. The World Health Organization highlights that in the United States, an estimated 1.3 million people experience medication-related harm, with 7,000-9,000 people dying due to a medication error each year (WHO, 2023). On average, one adverse drug effect (ADE) adds more than $2,000 to the cost …

Molecular Mechanisms Of Iron Metabolism And Overload, Aditi Tayal, Jasmeen Kaur, Robert W. Maitta

Faculty Scholarship

Iron represents an essential element required for normal physiologic processes throughout organ systems. A vast network of transporters is involved not only in uptake of this element but in processing, oxidation, and recycling to maintain it in a tight balance to avoid excess storage. This complex network of transporters, including heme and ferroportin, among many others, are responsible for facilitating inter-organ tissue iron exchange and availability, contributing to overall heme homeostasis. However, exposure to high levels of iron can overwhelm compensatory mechanisms that result in its accumulation and toxicity. This is the case of patients with genetic diseases such as …

Probing The Effect Of Peg-Dna Interactions And Buffer Viscosity On Tethered Dna In Shear Flow, Fatema Tuz Zohra, Huda Al-Zuhairi, Jefferson Reinoza, Hyeongjun Kim, Andreas Hanke

Mechanical Engineering Faculty Publications

DNA flow-stretching is a widely employed, powerful technique for investigating the mechanisms of DNA-binding proteins involved in compacting and organizing chromosomal DNA. We combine single-molecule DNA flow-stretching experiments with Brownian dynamics simulations to study the effect of the crowding agent polyethylene glycol (PEG) in these experiments. PEG interacts with DNA by an excluded volume effect, resulting in compaction of single, free DNA molecules in PEG solutions. In addition, PEG increases the viscosity of the buffer solution. By stretching surface-tethered bacteriophage lambda DNA in a flow cell and tracking the positions of a quantum dot labeled at the free DNA end …

Crossroads Of Covid-19 And Alzheimer’S: Investigating Sars-Cov-2 Nsp6 And Orf7a In Amyloid-Β42 Toxicity, Jeffrey William Huettemann, Amit Singh

Research from the Berry Summer Thesis Institute, 2025

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) resulted in several hundred million contracted cases of coronavirus disease 2019 (COVID-19) and a global pandemic. In some of these cases, previous neurological diseases, such as Alzheimer’s disease (AD), seemed to progress much more rapidly after the COVID-19 infection. Thus, we became interested in studying the effects of SARS-CoV-2 infection on prior neurological disease progressions.

To modulate this condition, we used Drosophila melanogaster as a genetic model system. We had previously developed the Alzheimer’s Disease Fly Model with expression of human amyloid beta 42 (Aβ42) peptide, which is responsible for extracellular Aβ-42 …

Astrocytes Expressing Mutant Hnrnpa1 Induce Non-Cell-Autonomous Motor Neuron Death, Qinxue Wu, Xionghao Liu, Tingting Zhang, Shiquan Cui, Bo Huang, Cao Huang, Qilin Cao, Xu-Gang Xia, Hongxia Zhou

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

Pathogenic mutation of heterogeneous nuclear ribonucleoprotein A1 (hnRNPA1) is causative to amyotrophic lateral sclerosis (ALS). Neuron death resulting from pathogenic hnRNPA1 may not require its presence across all pertinent cells types, including neurons, glia, and muscles. Rather, the exclusive presence of pathogenic hnRNPA1 in a specific cell type, such as astrocytes, may suffice to substantially alter cellular functions. Consequently, this alteration initiates abnormal interaction within intricate neuron-glia networks, culminating in non-cell-autonomous motor neuron death. To investigate the pivotal role of non-cell-autonomous neuron death in hnRNPA1-associated ALS, we developed transgenic rats overexpressing mutant hnRNPA1 in specifically astrocytes. The confined overexpression of …
