Targeted Protein Degradation Via Lysosomes, Rishi R Paudel, Dong Lu, Sandipan Roy Chowdhury, Erika Y Monroy, Jin Wang

Faculty, Staff and Students Publications

In the scope of targeted protein degradation (TPD), proteolysis-targeting chimeras (PROTACs), leveraging the ubiquitin-proteasome system, have been extensively studied. However, they are limited to the degradation of soluble and membrane proteins, excluding the aggregated and extracellular proteins and dysfunctional organelles. As an alternative protein degradation pathway, lysosomes serve as a feasible tool for accessing these untouched proteins and/or organelles by proteosomes. Here, we focus on reviewing the emerging lysosome-mediated TPD, such as AUTAC, ATTEC, AUTOTAC, LYTAC, and MoDE-A. Intracellular targets, such as soluble and aggregated proteins and organelles, can be degraded via the autophagy-lysosome pathway. Extracellular targets, such as membrane …

Faculty, Staff and Students Publications

Background

Computational fluid dynamics has shown good agreement with contrast‐enhanced magnetic resonance imaging measurements in cardiovascular disease applications. We have developed a biomechanical model of microvascular perfusion using contrast‐enhanced magnetic resonance imaging signal intensities derived from skeletal calf muscles to study peripheral artery disease (PAD).

Methods and Results

The computational microvascular model was used to study skeletal calf muscle perfusion in 56 individuals (36 patients with PAD, 20 matched controls). The recruited participants underwent contrast‐enhanced magnetic resonance imaging and ankle‐brachial index testing at rest and after 6‐minute treadmill walking. We have determined associations of microvascular model parameters including the transfer …

Evaluation Of Apparent Diffusion Coefficient Repeatability And Reproducibility For Preclinical Mris Using Standardized Procedures And A Diffusion-Weighted Imaging Phantom, Dariya Malyarenko, Ghoncheh Amouzandeh, Stephen Pickup, Rong Zhou, Henry Charles Manning, Seth T Gammon, Kooresh I Shoghi, James D Quirk, Renuka Sriram, Peder Larson, Michael T Lewis, Robia G Pautler, Paul E Kinahan, Mark Muzi, Thomas L Chenevert

Faculty, Staff and Students Publications

Relevant to co-clinical trials, the goal of this work was to assess repeatability, reproducibility, and bias of the apparent diffusion coefficient (ADC) for preclinical MRIs using standardized procedures for comparison to performance of clinical MRIs. A temperature-controlled phantom provided an absolute reference standard to measure spatial uniformity of these performance metrics. Seven institutions participated in the study, wherein diffusion-weighted imaging (DWI) data were acquired over multiple days on 10 preclinical scanners, from 3 vendors, at 6 field strengths. Centralized versus site-based analysis was compared to illustrate incremental variance due to processing workflow. At magnet isocenter, short-term (intra-exam) and long-term (multiday) …

Post-Transcriptional Regulation In Cranial Neural Crest Cells Expands Developmental Potential, Rachel A Keuls, Young Sun Oh, Ivanshi Patel, Ronald J Parchem

Faculty, Staff and Students Publications

Developmental potential is progressively restricted after germ layer specification during gastrulation. However, cranial neural crest cells challenge this paradigm, as they develop from anterior ectoderm, yet give rise to both ectodermal derivatives of the peripheral nervous system and ectomesenchymal bone and cartilage. How cranial neural crest cells differentiate into multiple lineages is poorly understood. Here, we demonstrate that cranial neural crest cells possess a transient state of increased chromatin accessibility. We profile the spatiotemporal emergence of premigratory neural crest and find evidence of lineage bias toward either a neuronal or ectomesenchymal fate, with each expressing distinct factors from earlier stages …

Structures Of Human Gastrin-Releasing Peptide Receptors Bound To Antagonist And Agonist For Cancer And Itch Therapy, Shuman Peng, Yuting Zhan, Dongqi Zhang, Lu Ren, Anqi Chen, Zhou-Feng Chen, Haitao Zhang

2020-Current year OA Pubs

Gastrin releasing peptide receptor (GRPR), a member of the bombesin (BBN) G protein-coupled receptors, is aberrantly overexpressed in several malignant tumors, including those of the breast, prostate, pancreas, lung, and central nervous system. Additionally, it also mediates non-histaminergic itch and pathological itch conditions in mice. Thus, GRPR could be an attractive target for cancer and itch therapy. Here, we report the inactive state crystal structure of human GRPR in complex with the non-peptide antagonist PD176252, as well as two active state cryo-electron microscopy (cryo-EM) structures of GRPR bound to the endogenous peptide agonist gastrin-releasing peptide and the synthetic BBN analog …

Keynote Unraveling Complex Problems: Applying Systems Thinking In Data Science, Ryan Nichols

SDSU Data Science Symposium

It would be an understatement to say that our world and its’ problems are as complex as ever. When developing models it is essential that we create some simplified view of a system in order to focus on relevant information, while remaining aware of interdependencies with external systems. While this is somethings we all do to explain events, correlations, or estimate the impact of a decision; how often do you practice this approach of thinking intentionally? As data scientist, we find ourselves increasingly looked to as a primary source for answers and solutions. This task comes with the responsibility to …

Working At An Assisted Living Facility During Covid, Anonymous

Community Reflections

For the past few years, learning how to deal with a pandemic referred to as Covid-19, was an everyday struggle for humankind. The fear of leaving your house to get groceries, or even going to work had people struggling to live the life of what was worry-free. At the very beginning of the pandemic, I was working at my very first job, which was at an assisted living facility. I was a server at the dining hall in the facility and made great connections with some really nice people. In the midst of the first wave of Covid, the facility …

Impact Of Population Based Indoor Residual Spraying With And Without Mass Drug Administration With Dihydroartemisinin-Piperaquine On Malaria Prevalence In A High Transmission Setting: A Quasi-Experimental Controlled Before-And-After Trial In Northeastern Uganda, Richard C. Elliott

Materials Science and Engineering Faculty Publications and Presentations

Background: Declines in malaria burden in Uganda have slowed. Modelling predicts that indoor residual spraying (IRS) and mass drug administration (MDA), when co-timed, have synergistic impact. This study investigated additional protective impact of population-based MDA on malaria prevalence, if any, when added to IRS, as compared with IRS alone and with standard of care (SOC).

Methods: The 32-month quasi-experimental controlled before-and-after trial enrolled an open cohort of residents (46,765 individuals, 1st enumeration and 52,133, 4th enumeration) of Katakwi District in northeastern Uganda. Consented participants were assigned to three arms based on residential subcounty at study start: MDA+IRS, IRS, SOC. IRS …

Covid-19 Reflection, Anonymous

Community Reflections

The COVID-19 Pandemic was one of the most difficult times in recent history for not only the infected, but also the general public. When COVID-19 first became an issue in the United States with schools closing down for two weeks in March of 2020, I was a junior attending a private, all-boys high school. When the school officially closed, we began virtual classes which was a difficult adjustment due to classes being taught on Zoom and the schedules of classes being strangely different. This form of learning was difficult for me personally.
