Experimental studies suggest that animal species not previously described as naturally infected by prions are susceptible to prion diseases affecting sheep, cattle, and deer. These interspecies transmissions may generate prions with unknown host ranges. Pigs are susceptible to prions from different origins, including deer chronic wasting disease (CWD), sheep scrapie, and bovine spongiform encephalopathy (BSE). Here, we studied prions in brains and muscles from pigs previously infected with these different prion sources. Specifically, we measured the total prion protein (PrP) and PK-resistant PrP by western blot. Seeding activity in these tissues was evaluated using the protein misfolding cyclic amplification (PMCA) …

Inhibition Of The Ufd-1-Npl-4 Complex Triggers An Aberrant Immune Response In Caenorhabditis Elegans, Rajneesh Rao, Alejandro Aballay, Jogender Singh

Faculty, Staff and Student Publications

The UFD-1 (ubiquitin fusion degradation 1)-NPL-4 (nuclear protein localization homolog 4) heterodimer is involved in extracting ubiquitinated proteins from several plasma membrane locations, including the endoplasmic reticulum. This heterodimer complex helps in the degradation of ubiquitinated proteins via the proteasome with the help of the AAA+ATPase CDC-48. While the ubiquitin-proteasome system is known to have important roles in maintaining innate immune responses, the role of the UFD-1-NPL-4 complex in regulating immunity remains elusive. In this study, we investigate the role of the UFD-1-NPL-4 complex in maintaining

Follicular lymphoma (FL) has a clinical course that is often characterized by high response rates to first-line therapy, followed by multiple relapses over a prolonged natural history. Currently, there are multiple possible approaches to frontline therapy for untreated advanced-stage FL, but there is an ongoing debate around what is the preferred approach. Based on the benefits seen with combining lenalidomide, an immunomodulatory agent, with rituximab, an anti-CD20 antibody, we aimed to evaluate the safety and efficacy of lenalidomide in combination with obinuzutumab, an anti-CD20 antibody with enhanced antibody-dependent cellular cytotoxicity. The eligibility criteria included a diagnosis of FL, grade 1 …

Background: In the phase 3 FRESCO (NCT02314819) and FRESCO-2 (NCT04322539) studies, fruquintinib vs placebo, plus best supportive care, significantly improved overall survival (OS) in patients with metastatic colorectal cancer (mCRC). These studies were conducted in temporally and geographically diverse populations that received distinct prior therapies; FRESCO patients were less pretreated than FRESCO-2 patients. This analysis assessed the efficacy and safety of fruquintinib in a less pretreated global population than the FRESCO-2 intention-to-treat (ITT) population.

Methods: In FRESCO and FRESCO-2, patients were randomized 2:1 to receive oral fruquintinib 5 mg or matched placebo. Profile matching was undertaken …

Single-cell studies on breast tissue have contributed to a change in our understanding of breast epithelial diversity that has, in turn, precipitated a lack of consensus on breast cell types. The confusion surrounding this issue highlights a possible challenge for advancing breast atlas efforts. In this perspective, we present our consensus on the identities, properties, and naming conventions for breast epithelial cell types and propose goals for future atlas endeavors. Our proposals and their underlying thought processes aim to catalyze the adoption of a shared model for this tissue and to serve as guidance for other investigators facing similar challenges.

Introduction: Exposure to prescription opioids following traumatic injury can increase the risk of developing tolerance, persistent opioid use and opioid use disorder. The mechanisms underlying opioid tolerance or dependence are not well understood, and no biomarkers predict risk. Opioid exposure causes epigenetic modifications, including alterations in microRNA (miRNA) expression. Several miRNAs, which regulate synaptic plasticity, are hypothesised to underlie substance use disorders and influence µ-opioid receptor levels, modulating opioid tolerance. This project aims to develop a bio-behavioural signature to predict persistent opioid use and chronic pain up to 6 months post-discharge.

Methods and analysis: The study will use a prospective …

Evidence links air pollution to dementia, yet its role in Lewy body dementia (LBD) remains unclear. Here we showed in a cohort of 56.5 million individuals across the U.S. that PM2.5 exposure raises LBD risk. Mechanistically, we found PM2.5 exposure led to brain atrophy in wild-type mice, an effect not seen in α-synuclein (αSyn)-deficient mice. PM2.5 exposure generated a highly pathogenic αSyn strain, PM-PFF, with enhanced proteinase K-resistance and neurotoxicity, resembling αSyn LBD strains. PM2.5 samples from China, the U.S., and Europe consistently induced proteinase-resistant αSyn strains and in vivo pathology. Transcriptomic analyses revealed shared responses between PM2.5-exposed mice and …

HPV integration disrupts host genomic structure and expression, but whether these alterations promote cancer development remains unclear. Multiple genomic analyses of oropharyngeal cancers identified several host fusion genes, including recurrent FGFR3-TACC3 fusions, expressed from rearranged genomic loci adjacent to HPV integration sites. Evolutionary modeling implicated integration of virus concatemers into the host genome as a common initiating event in fusion formation. Co-expression of HPV16 E6/E7 and FGFR3-TACC3, but neither alone, was sufficient for tumor development in both xenograft and syngeneic mouse models and led to unique transcriptional programs implicated in carcinogenesis. FGFR3-TACC3 expression decreased the ubiquitination and degradation of …

KRAS is among the most frequently mutated oncogenes in cancer, and for decades, efforts at pharmacological blockade of its function in solid cancers have been unsuccessful. A notable advance in this endeavor is the recent development of small molecule KRAS inhibitors, which enable direct targeting of the mutant oncoprotein. Here, we comprehensively evaluate the pre-clinical efficacy of BI-2493 a panKRASi, a first-in-class allele agnostic mutant KRAS inhibitor, in pancreatic ductal adenocarcinoma (PDAC). We report effective tumor growth suppression across a broad range of models, including cell lines, patient-derived xenografts (PDXs), syngeneic orthotopic models, and prolonged survival in genetically engineered mouse …

Aberrant levels or structures of RNA isoforms are a hallmark of many cancers, including acute myeloid leukemia (AML), yet their role in AML chemoresistance remains unclear. We conducted a paired analysis of RNA isoform changes in patients with AML before therapy and at relapse after chemotherapy and identified intragenic DNA methylation at the proximal promoter of the transcription factor RUNX1, which resulted in elevated expression of the long-isoform RUNX1C through its alternative distal promoter. The unique N-terminal region of RUNX1C orchestrated an isoform-specific transcriptional program that promoted chemoresistance, with its direct target BTG2 playing a role in chemotherapy resistance. …

Ferroptosis, an iron-dependent form of cell death, holds promise for cancer therapy. However, the intricate link between ferroptosis and oncogenic mutations remains unclear. Here we show that SMARCA4, a well-established tumour suppressor whose deficiency is associated with poor prognosis and resistance to treatments, sensitizes non-small cell lung cancer (NSCLC) cells to ferroptosis. Mechanistically, SMARCA4 promotes chromatin accessibility and expression of ALDH16A1. Surprisingly, ALDH16A1 lacks ALDH enzymatic activity, but binds to the anti-ferroptotic oxidoreductase thioredoxin (TXN), facilitating its translocation to the lysosome and subsequent degradation. Meanwhile, ALDH16A1 directly inhibits TXN's oxidoreductase function by occluding its active site. We also show that …

The MAPK pathway can drive resistance in highly aggressive breast cancers. Our previous work showed that the MEK inhibitor (MEKi) AZD6244 (selumetinib) prevented lung metastasis in a breast cancer xenograft model. In clinical studies, MEKis as single agents have had only modest activity against solid tumors due to the onset of resistance. Using synthetic lethality siRNA screening, we identified myeloid cell leukemia-1 (MCL-1) as a potential contributor to AZD6244 resistance. We hypothesized that MCL-1 promotes MEKi resistance in highly aggressive breast cancers and that MCL-1 inhibition overcomes AZD6244 resistance. We established two AZD6244-resistant cell lines: MDA-MB-231-R (triple-negative breast cancer) and …

Background: Hodgkin lymphoma has excellent survival rates in adolescents and young adults (AYA, diagnosed between ages 15 and 39 years). However, survivors are at risk of treatment-related late effects. Whereas radiotherapy (RT) de-escalation/omission has emerged as an approach to minimize late effects, no prior studies have evaluated RT use over time in AYAs with Hodgkin lymphoma.

Methods: Using the National Cancer Database, we identified 40,717 AYAs diagnosed with Hodgkin lymphoma between 2004 and 2020. Differences in sociodemographic and clinical variables were assessed using a two-sample two-sided t test or χ2 test. RT use was summarized per year by frequency with …

The ataxia telangiectasia and RAD3-related (ATR) kinase functions with ataxia telangiectasia-mutated (ATM) kinase as a modulator of DNA damage response (DDR). We assessed the antitumor effects of the ATR inhibitor elimusertib (BAY-1895344) in patient-derived xenograft (PDX) models with DDR alterations. Antitumor activity was assessed by change in tumor volume (TV) from baseline. Responses were categorized as follows: partial response (PR), ≥30% decrease in TV; ≥20% increase in TV, progressive disease; and non-PR/progressive disease, stable disease (SD). Event-free survival was defined as time for tumor doubling (EFS-2). Of 21 PDX models tested, 11 had significant prolongation of EFS-2 with elimusertib monotherapy. …

Faculty, Staff and Student Publications

Treatment-resistant depression (TRD) represents a severe and complex subtype of major depressive disorder (MDD), affecting approximately 30% of patients who fail to respond adequately to multiple standard antidepressant therapies. While the pathophysiology of TRD remains incompletely understood, emerging evidence suggests that sex-based biological differences might influence its onset, progression, and treatment response. Women are disproportionately affected by depression and are more likely to experience residual symptoms and treatment resistance, potentially due to hormonal fluctuations, immune system differences, and variations in brain circuitry and neuroplasticity. This narrative explores the current literature on the mechanisms underlying TRD, with a particular emphasis on …

The origin of mucinous cystic neoplasms (MCNs) remains a major challenge in hepato-pancreato-biliary pathology. These cystic tumors are defined by their mucinous epithelium and ovarian-like stroma, with an estimated 10% risk of progression to invasive carcinoma. The origin of the ovarian-like stroma remains a subject of debate. In this study, we conducted immunohistochemical profiling, targeted DNA sequencing, and genome-wide DNA methylation analysis on a cohort of 15 pancreatic MCNs (MCN-P) and six hepatic MCNs (MCN-L). Using immunohistochemistry and targeted DNA sequencing, we unequivocally established the diagnosis of MCN.

Topologically associating domains (TADs) and chromatin architectural loops impact promoter-enhancer interactions, with CCCTC-binding factor (CTCF) defining TAD borders and loop anchors. TAD boundaries and loops progressively strengthen upon embryonic stem (ES) cell differentiation, underscoring the importance of chromatin topology in ontogeny. However, the mechanisms driving this process remain unclear. Here we show a widespread increase in CTCF-RNA-binding protein (RBP) interactions upon ES to neural stem (NS) cell differentiation. While dispensable in ES cells, RBPs reinforce CTCF-anchored chromatin topology in NS cells. We identify Pantr1, a non-coding RNA, as a key facilitator of CTCF-RBP interactions, promoting chromatin maturation. Using acute CTCF …

Candida albicans, an opportunistic fungal pathogen, causes systemic and superficial infections, especially in immunocompromised patients. Treatment of fungal infections is complicated by limited antifungal options and the development of drug resistance. Previous work from our group demonstrated the efficacy of the anti-virulence peptide EntV and shorter variants against C. albicans infection in various animal models, including mouse models of oropharyngeal candidiasis and disseminated infection and a rat venous catheter model. However, the mechanism of action, which abrogates fungal virulence without fungicidal or fungistatic activity, has remained unknown. We used a combination of cell biological, biochemical, genomic, and genetic approaches to …

Developmental domains, such as cognitive, language, and motor, are key concepts of interest in longitudinal studies of intellectual and developmental disabilities (IDD). Normative scores (e.g., IQ) are often used to operationalize performance on standardized tests of these concepts, but it is the interval-distributed person-ability scores that are intended for the assessment of within-individual change. Here we illustrate the use and interpretation of several Stanford Binet, 5th Edition score types (IQ, extended IQ, Z-normalized raw score, developmental quotient, raw sum score, age equivalent, and ability score) using data from two longitudinal studies of rare genetic conditions associated with IDD. We found …

Contingency management (CM) relies on motivation and reward processing and is among the most effective treatments available for cocaine use disorder (CUD), yet success rates do not meet desired clinical efficacy. To improve treatment-individual fit, we investigated the late positive potential (LPP), a measure of incentive salience to cues, as a predictor of treatment response. Treatment-seeking adults with CUD (N = 58) completed an EEG task where they viewed pleasant, unpleasant, cocaine, and neutral images. Participants received CM and counseling for four weeks. Urine was collected thrice weekly. We defined incentive salience to cues by A) cluster analyses on LPP …

Background: Hispanics have been historically underrepresented in epidemiologic cancer research. Existing cohort studies focused on recruiting Hispanic participants have been relatively small, making studying cancer outcomes challenging. Therefore, we aimed to compare the distribution of cancer risk factors among Hispanic women of Mexican heritage (HWMH) participating in existing cohorts to explore the possibility of future data pooling efforts.

Methods: We used baseline data of HWMH from three US-based studies, the Mexican American Cohort (MAC; n = 19,797; 2001-2017), the Multiethnic Cohort (MEC; n = 18,007; 1993-1996), and the Hispanic Community Health Study/Study of Latinos (HCHS/SOL; n = 4,022; 2008-2011), and …
