UNLABELLED: Molecular signatures predict prognosis in hepatocellular carcinoma, but their relevance to transarterial radioembolization (TARE) with yttrium-90 (90Y) is unknown. We aimed to identify baseline and treatment-induced pathways associated with response and nominate biomarkers. Ten transcriptomically diverse human liver cancer cell lines were exposed to escalating activities of glass 90Y microspheres for 10 days. Normalized AUC values quantified sensitivity. Whole-transcriptome RNA sequencing at baseline and after treatment was analyzed with elastic net regression and gene set enrichment. Findings were corroborated by qRT-qPCR and exploratory analysis of pretreatment tumor samples from patients undergoing TARE. Liver cancer cell line responses to 90Y …

The Cognitive-Affective Social Processing And Emotion Regulation (Casper) Model, M Catalina Camacho, Elina Deshpande, Michael T Perino

2020-Current year OA Pubs

Humans are intensely social creatures. It is therefore not surprising that many psychiatric disorder criteria include social dysfunctions; however, overlapping presentations and diverse, complex etiologies make treating social dysfunctions difficult. Here, we introduce the Cognitive Affective Social Processing and Emotion Regulation (CASPER) model. CASPER integrates research from social psychology, cognitive neuroscience, and developmental science to describe how real-world social processing unfolds and is associated with differing psychiatric social cognitive neurophenotypes. Briefly, social processing can be broken down into the following cognitive steps: identifying relevant social cues, attending to related cues, interpreting cues, and adjusting behavior appropriately. Each of these steps …

Mutations In Hsp40 Co-Chaperone Change The Canonical Interdomain Interactions Stimulating Lgmdd1 Myopathy, Ankan K Bhadra, Geetika Aggarwal, Anshuman Jaysingh, Daniel Chen, Jil Daw, Conrad C Weihl, Heather L True

2020-Current year OA Pubs

Limb-girdle muscular dystrophy D1 (LGMDD1) is a rare, dominantly inherited neuromuscular protein-misfolding chaperonopathy caused by mutations in the Hsp40 co-chaperone DNAJB6, primarily in the glycine-phenylalanine (GF) or J-domains. Currently, no treatments are available, and a challenge in understanding the disease is identifying a specific client protein for DNAJB6 in skeletal muscle. DNAJB6 has homology to the yeast DNAJ family member, Sis1. Our previous research indicated that LGMDD1 GF domain mutants in Sis1 exhibit substrate-specific effects, influenced by Hsp70 activity. Herein, we employed functional assays along with advanced molecular simulation studies to understand the regulatory interdomain interactions in disease-causing mutants of …

Diverse Misfolding Mutant Digestive Enzymes Cause Chronic Pancreatitis Through Common Pathways, Steven J Wilhelm, Grace E Curry, Neel Matiwala, Jianguo Lin, Tran Quach, Mark E Lowe, Miklós Sahin-Tóth, Xunjun K Xiao

2020-Current year OA Pubs

BACKGROUND & AIMS: Increasing evidence suggests that protein misfolding and proteotoxicity is an important mechanism of chronic pancreatitis (CP) in patients with genetic variants. Two mouse models carrying misfolding digestive enzyme variants, CPA1 N256K and PNLIP T221M, recapitulate the human CP phenotype. We hypothesized that both models develop CP through similar disease mechanisms.

METHODS: We conducted a comprehensive analysis of mice aged 1 to 6 months using histology, immunohistochemistry, protein immunoblotting, quantitative polymerase chain reaction (qPCR), transmission electron microscopy (TEM), and RNA sequencing (RNA-seq) analysis to characterize pancreatic pathological changes.

RESULTS: Both homozygous models exhibited CP hallmarks, including progressive acinar …

Airway Management In Emergency Department Thoracotomy: A Narrative Review, Aaron J Lacy, Adam Liebendorfer, Sarah M Guess, Rami S Al-Aref, Anthony P Kronfli, Rachel E Armstrong, Amelia W Maiga, Alexander Bracey, Ryan N Barnicle

2020-Current year OA Pubs

INTRODUCTION: Emergency department thoracotomy (EDT) is a high-risk, life-saving intervention for patients in traumatic cardiac arrest. A critical component of EDT is airway management, typically performed by emergency physicians, yet formal guidance regarding optimal strategies remains limited. Airway management in this setting is uniquely complex due to concurrent anatomic injury, physiologic instability, and the procedural demands of thoracotomy.

DISCUSSION: Endotracheal intubation (ETI) during EDT presents multiple challenges. Anatomic difficulties may arise from facial or cervical trauma, restricted positioning, and the presence of cervical collars. Cognitive load is heightened by the chaotic, multidisciplinary environment, requiring strategies such as pre-briefing, checklists, and …

Atomic Models Of The Toxoplasma Cell Invasion Machinery, Jianwei Zeng, Yong Fu, Pengge Qian, Wei Huang, Qingwei Niu, Wandy L Beatty, Alan Brown, L David Sibley, Rui Zhang

2020-Current year OA Pubs

Apicomplexan parasites, responsible for toxoplasmosis, cryptosporidiosis and malaria, invade host cells through a unique gliding motility mechanism powered by actomyosin motors and a dynamic organelle called the conoid. Here, using cryo-electron microscopy, we determined structures of four essential complexes of the Toxoplasma gondii conoid: the preconoidal P2 ring, tubulin-based conoid fibers, and the subpellicular and intraconoidal microtubules. Our analysis identified 40 distinct conoid proteins, several of which are essential for parasite lytic growth, as revealed through genetic disruption studies. Comparative analysis of the tubulin-containing complexes sheds light on their functional specialization by microtubule-associated proteins, while the structure of the preconoidal …

Mouse Alport Podocytes Are Susceptible To Aav9 Transduction In Vivo, Meei-Hua Lin, Kohei Omachi, Joshua F Begin, Jennifer L Richardson, Jeffrey H Miner

2020-Current year OA Pubs

INTRODUCTION: Alport syndrome features a defective glomerular basement membrane (GBM) due to variants in COL4A3, COL4A4, and COL4A5. The most severe forms, which lack the GBM's collagen α3α4α5(IV) network, progress from hematuria in early childhood to proteinuria, chronic kidney disease, and kidney failure by the age of ∼30. As a monogenic disease without specific treatments, and with podocytes being the only glomerular cells that synthesize collagen α3α4α5(IV), the ability to efficiently deliver genes to Alport podocytes could open up new possibilities for treatment.

METHODS: As a proof-of-concept study, we investigated whether podocytes in X-linked Alport mice were susceptible to transduction …
