Bladder cancer (BLCA) genomic profiling has identified molecular subtypes with distinct clinical characteristics and variable sensitivities to frontline therapy. BLCAs can be categorized into luminal or basal subtypes based on their gene expression. We comprehensively characterized nine human BLCA cell lines (UC3, UC6, UC9, UC13, UC14, T24, SCaBER, RT4V6 and RT112) into molecular subtypes using orthotopic xenograft models. Patient-derived, luciferase-tagged BLCA cell lines were cultured in vitro and engrafted into bladders of NSG mice. Tumor growth was monitored using bioluminescence imaging and mRNA-based molecular classification was used to characterize xenografts into molecular subtypes. RNAseq analysis and basal, luminal, and epithelial-mesenchymal …

Faculty, Staff and Student Publications

Prediction and avoidance of intraoperative hypotension (IOH) can lead to less postoperative morbidity. Machine learning (ML) is increasingly being applied to predict IOH. We hypothesize that incorporating demographic and physiological features in an ML model will improve the performance of IOH prediction. In addition, we added a "dial" feature to alter prediction performance. An ML prediction model was built based on a multivariate random forest (RF) trained algorithm using 13 physiologic time series and patient demographic data (age, sex, and BMI) for adult patients undergoing hepatobiliary surgery. A novel implementation was developed with an adjustable, multi-model voting (MMV) approach to …

Hsp90: Bringing It All Together, Georgios Ioannis Karras, Giorgio Colombo, Andrea N Kravats

Faculty, Staff and Student Publications

Heat-shock protein 90 (Hsp90) is an ancient and multifaceted protein-folding machine essential for most organisms. The past 40 years have uncovered remarkable complexity in the regulation and function of Hsp90, which dwarfs most other machines in the cell in sophistication. Here, we propose four analogies to illustrate Hsp90's sophistication: a multifunctional Swiss Army knife, an automobile engine and its controls, a switchboard acting as a hub and directing signals, and an orchestra conductor setting the tempo of a symphony. Although each of these analogies represents some key Hsp90 activities, none of them captures the entirety of Hsp90's complexity. Together, these …

Toward A Biological Definition Of Neuronal And Glial Synucleinopathies, Claudio Soto, Brit Mollenhauer, Oskar Hansson, Un Jung Kang, Roy N Alcalay, David Standaert, Claudia Trenkwalder, Kenneth Marek, Douglas Galasko, Kathleen Poston

Faculty, Staff and Student Publications

Cerebral accumulation of alpha-synuclein (αSyn) aggregates is the hallmark event in a group of neurodegenerative diseases-collectively called synucleinopathies-which include Parkinson's disease, dementia with Lewy bodies and multiple system atrophy. Currently, these are diagnosed by their clinical symptoms and definitively confirmed postmortem by the presence of αSyn deposits in the brain. Here, we summarize the drawbacks of the current clinical definition of synucleinopathies and outline the rationale for moving toward an earlier, biology-anchored definition of these disorders, with or without the presence of clinical symptoms. We underscore the utility of the αSyn seed amplification assay to detect aggregated αSyn in living …

Undervaluing Nondrug Rewards Or Overvaluing Cocaine? Cocaine Demand Relates To Cocaine Use Severity More Strongly Than Anhedonia In Individuals With Cocaine Use Disorder, Cecilia Nunez, Jin H Yoon, Constanza De Dios, Vincent Dang, Scott D Lane, Jessica N Vincent, Joy M Schmitz, Margaret C Wardle

Faculty, Staff and Student Publications

Cocaine use disorder (CUD) is a major public health issue, and greater cocaine use severity has been associated with worse treatment retention and outcomes. Therefore, greater understanding of processes that influence cocaine use is needed. Both anhedonia (i.e., undervaluation of non-drug rewards) and cocaine demand (i.e., cocaine valuation) are related to cocaine use severity and thematically related to each other at face value, but no studies have directly compared these outcomes to our knowledge. The current study represents a secondary analysis from a two-phase sequential, multiple assignment, randomized trial (SMART) aimed at developing adaptive interventions for CUD. We examined the …
