Drug Discovery Targeting The Disorder-To-Order Transition Regions Through The Conformational Diversity Mimicking And Statistical Analysis, Insung Na, Sungwoo Choi, Seung Han Son, Vladimir N. Uversky, Chul Geun Kim Jan 2020

Drug Discovery Targeting The Disorder-To-Order Transition Regions Through The Conformational Diversity Mimicking And Statistical Analysis, Insung Na, Sungwoo Choi, Seung Han Son, Vladimir N. Uversky, Chul Geun Kim

Molecular Medicine Faculty Publications

Intrinsically disordered proteins exist as highly dynamic conformational ensembles of diverse forms. However, the majority of virtual screening only focuses on proteins with defined structures. This means that computer-aided drug discovery is restricted. As a breakthrough, understanding the structural characteristics of intrinsically disordered proteins and its application can open the gate for unrestricted drug discovery. First, we segmented the target disorder-to-order transition region into a series of overlapping 20-amino-acid-long peptides. Folding prediction generated diverse conformations of these peptides. Next, we applied molecular docking, new evaluation score function, and statistical analysis. This approach successfully distinguished known compounds and their corresponding binding …


Yersinia Outer Membrane Vesicles As Potential Vaccine Candidates In Protecting Against Plague, Andrey A. Byvalov, Ilya V. Konyshev, Vladimir N. Uversky, Svetlana V. Dentovskaya, Andrey P. Anisimov Jan 2020

Yersinia Outer Membrane Vesicles As Potential Vaccine Candidates In Protecting Against Plague, Andrey A. Byvalov, Ilya V. Konyshev, Vladimir N. Uversky, Svetlana V. Dentovskaya, Andrey P. Anisimov

Molecular Medicine Faculty Publications

Despite the relatively low incidence of plague, its etiological agent, Yersinia pestis, is an exceptional epidemic danger due to the high infectivity and mortality of this infectious disease. Reports on the isolation of drug-resistant Y. pestis strains indicate the advisability of using asymmetric responses, such as phage therapy and vaccine prophylaxis in the fight against this problem. The current relatively effective live plague vaccine is not approved for use in most countries because of its ability to cause heavy local and system reactions and even a generalized infectious process in people with a repressed immune status or metabolic disorders, as …


Yersinia Pestis Plasminogen Activator, Florent Sebbane, Vladimir N. Uversky, Andrey P. Anisimov Jan 2020

Yersinia Pestis Plasminogen Activator, Florent Sebbane, Vladimir N. Uversky, Andrey P. Anisimov

Molecular Medicine Faculty Publications

The Gram-negative bacterium Yersinia pestis causes plague, a fatal flea-borne anthropozoonosis, which can progress to aerosol-transmitted pneumonia. Y. pestis overcomes the innate immunity of its host thanks to many pathogenicity factors, including plasminogen activator, Pla. This factor is a broad-spectrum outer membrane protease also acting as adhesin and invasin. Y. pestis uses Pla adhesion and proteolytic capacity to manipulate the fibrinolytic cascade and immune system to produce bacteremia necessary for pathogen transmission via fleabite or aerosols. Because of microevolution, Y. pestis invasiveness has increased significantly after a single amino-acid substitution (I259T) in Pla of one of the oldest Y. pestis …

Linear Relationships Between Partition Coefficients Of Different Organic Compounds And Proteins In Aqueous Two-Phase Systems Of Various Polymer And Ionic Compositions, Nuno R. Da Silva, Luisa A. Ferreira, Pedro P. Madeira, José A. Teixeira, Vladimir N. Uversky, Boris Y. Zaslavsky

Molecular Medicine Faculty Publications

Analysis of the partition coefficients of small organic compounds and proteins in different aqueous two-phase systems under widely varied ionic compositions shows that logarithms of partition coefficients for any three compounds or proteins or two organic compounds and one protein are linearly interrelated, although for protein(s) there are ionic compositions when the linear fit does not hold. It is suggested that the established interrelationships are due to cooperativity of different types of solute–solvent interactions in aqueous media. This assumption is confirmed by analysis of distribution coefficients of various drugs in octanol-buffer systems with varied ionic compositions of the buffer. Analysis …


The Pathophysiological Significance Of Fibulin-3, Imogen Livingstone, Vladimir N. Uversky, Dominic Furniss, Akira Wiberg Jan 2020

The Pathophysiological Significance Of Fibulin-3, Imogen Livingstone, Vladimir N. Uversky, Dominic Furniss, Akira Wiberg

Molecular Medicine Faculty Publications

Fibulin-3 (also known as EGF-containing fibulin extracellular matrix protein 1 (EFEMP1)) is a secreted extracellular matrix glycoprotein, encoded by the EFEMP1 gene that belongs to the eight-membered fibulin protein family. It has emerged as a functionally unique member of this family, with a diverse array of pathophysiological associations predominantly centered on its role as a modulator of extracellular matrix (ECM) biology. Fibulin-3 is widely expressed in the human body, especially in elastic-fibre-rich tissues and ocular structures, and interacts with enzymatic ECM regulators, including tissue inhibitor of metalloproteinase-3 (TIMP-3). A point mutation in EFEMP1 causes an inherited early-onset form of macular …

Chromatin remodeling, including histone modification, chromatin (un)folding, and nucleosome remodeling, is a significant transcriptional regulation mechanism. By these epigenetic modifications, transcription factors and their regulators are recruited to the promoters of target genes, and thus gene expression is controlled through either transcriptional activation or repression. The Mat1-mediated transcriptional repressor (MMTR)/DNA methyltransferase 1 (DNMT1)-associated protein (Dmap1) is a transcription corepressor involved in chromatin remodeling, cell cycle regulation, DNA double-strand break repair, and tumor suppression. The Tip60-p400 complex proteins, including MMTR/Dmap1, interact with the oncogene Myc in embryonic stem cells (ESCs). These proteins interplay with the stem cell-related proteome networks and regulate …

Extensive non-pharmaceutical and physical distancing measures are currently the primary interventions against coronavirus disease 2019 (COVID-19) worldwide. It is therefore urgent to estimate the impact such measures are having. We introduce a Bayesian epidemiological model in which a proportion of individuals are willing and able to participate in distancing, with the timing of distancing measures informed by survey data on attitudes to distancing and COVID-19. We fit our model to reported COVID-19 cases in British Columbia (BC), Canada, and five other jurisdictions, using an observation model that accounts for both underestimation and the delay between symptom onset and reporting. We …

Modeling The Role Of Asymptomatics In Infection Spread With Application To Sars-Cov-2, Hana M. Dobrovolny

All publications

SARS-CoV-2 started causing infections in humans in late 2019 and has spread rapidly around the world. While the number of symptomatically infected and severely ill people is high and has overwhelmed the medical systems of many countries, there is mounting evidence that some of the rapid spread of this virus has been driven by asymptomatic infections. In this study, we use a compartmental mathematical model of a viral epidemic that includes asymptomatic infection to examine the role of asymptomatic individuals in the spread of the infection. We apply the model to epidemics in California, Florida, New York, and Texas, finding …

The origin of the severe acute respiratory syndrome-coronavirus 2 (SARS-CoV-2) virus causing the COVID-19 pandemic has not yet been fully determined. Despite the consensus about the SARS-CoV-2 origin from bat CoV RaTG13, discrepancy to host tropism to other human Coronaviruses exist. SARS-CoV-2 also possesses some differences in its S protein receptor-binding domain, glycan-binding N-terminal domain and the surface of the sialic acid-binding domain. Despite similarities based on cryo-EM and biochemical studies, the SARS-CoV-2 shows higher stability and binding affinity to the ACE2 receptor. The SARS-CoV-2 does not appear to present a mutational “hot spot” as only the D614G mutation has …

Untreated Stroke As Collateral Damage Of Covid-19: “Time Is Brain” Versus “Stay At Home”:, David Z. Rose, W. Scott Burgin, Swetha Renati Jan 2020

Untreated Stroke As Collateral Damage Of Covid-19: “Time Is Brain” Versus “Stay At Home”:, David Z. Rose, W. Scott Burgin, Swetha Renati

All publications

For decades, neurologists have been advocating that anyone with acute focal deficits report immediately to the closest hospital’s emergency room. Major advancements in the hyperacute diagnosis and treatment of stroke have justified our call-to-action slogan of “Time is Brain”—faster therapy leads to superior outcomes. However, this mantra has been recently usurped by the catchphrase “Stay at Home” during the coronavirus disease 2019 (COVID-19) pandemic. Fewer patients are presenting to hospitals with acute stroke; our census is down. Presumably the etiology of this phenomenon is either strict “social distancing” that some people may misperceive to exclude even emergent situations, or fears …

Education Reforms For Inclusion? Interrogating Policy-Practice Disjunctions In Early Childhood Education In Bulgaria, Veselina Lambrev, Anna Kirova, Larry Prochner

Teaching and Learning Faculty Publications

This article examines how early childhood educators, as policy implementers, perceive reforms in Bulgaria’s education system that occurred between 2008 and 2018. Both Roma and non-Roma educators participated in this project that compares perceptions of Bulgarian teachers in public schools and Roma educators in informal educational settings operated by NGOs and religious institutions. Applying intersectionality as a framework, the study draws from anti-Romaism as a particular form of racism that militates against the inclusion of Roma to examine whether and to what extent discourses of minoritized and racialised children are evident in the views held by the Bulgarian educators, resulting, …

Type 1 diabetes (T1D) results in the loss of pancreatic beta cells and subsequent loss of insulin production. Exogenous insulin is the only effective treatment, but there is still no cure or interventional therapy available to inhibit progression of T1D. Successful T1D interventional therapy must protect pancreatic beta cells from autoimmunity while enhancing beta cell survival and function. Our data suggests Cornus officinalis (CO) may be a candidate for interventional therapy to protect pancreatic beta cells from autoimmune attack and increase their function. CO has been used in traditional Chinese medicine (TCM) for over 2,000 years and has shown characteristics …

As coral reefs continue to decline due to climate change and other stressors, scientists have proposed adopting genomic tools, such as biomarkers, to aid in the conservation and restoration of these threatened ecosystems. Biomarkers are easily measured indicators of biological processes that can be used to predict or diagnose health, resilience, and other key performance metrics. The ultimate goal of developing biomarkers is to determine the conservation value and utility of a given coral colony, including the host animal, its algal symbionts, and their microbial partners. However, this goal remains distant because most efforts have not yet moved beyond the …
