Uncovering Tumour Heterogeneity Through Pkr And Nc886 Analysis In Metastatic Colon Cancer Patients Treated With 5-Fu-Based Chemotherapy, María Belén Ortega-García, Igor Zwir, Et Al

Open Access Publications

Colorectal cancer treatment has advanced over the past decade. The drug 5-fluorouracil is still used with a wide percentage of patients who do not respond. Therefore, a challenge is the identification of predictive biomarkers. The protein kinase R (PKR also called EIF2AK2) and its regulator, the non-coding pre-mir-nc886, have multiple effects on cells in response to numerous types of stress, including chemotherapy. In this work, we performed an ambispective study with 197 metastatic colon cancer patients with unresectable metastases to determine the relative expression levels of both nc886 and PKR by qPCR, as well as the location of PKR by …

Photoreceptor Responses To Light In The Pathogenesis Of Diabetic Retinopathy, Shahriyar P Majidi, Rithwick Rajagopal

Open Access Publications

Vision loss, among the most feared complications of diabetes, is primarily caused by diabetic retinopathy, a disease that manifests in well-recognized, characteristic microvascular lesions. The reasons for retinal susceptibility to damage in diabetes are unclear, especially considering that microvascular networks are found in all tissues. However, the unique metabolic demands of retinal neurons could account for their vulnerability in diabetes. Photoreceptors are the first neurons in the visual circuit and are also the most energy-demanding cells of the retina. Here, we review experimental and clinical evidence linking photoreceptors to the development of diabetic retinopathy. We then describe the influence of …

Bet Bromodomain Inhibition Attenuates Cardiac Phenotype In Myocyte-Specific Lamin A/C-Deficient Mice, Gaelle Auguste, Leila Rouhi, Scot J Matkovich, Cristian Coarfa, Matthew J Robertson, Grazyna Czernuszewicz, Priyatansh Gurha, Ali J Marian

Open Access Publications

Mutation in the LMNA gene, encoding lamin A/C, causes a diverse group of diseases called laminopathies. Cardiac involvement is the major cause of death and manifests as dilated cardiomyopathy, heart failure, arrhythmias, and sudden death. There is no specific therapy for LMNA-associated cardiomyopathy. We report that deletion of Lmna in cardiomyocytes in mice leads to severe cardiac dysfunction, conduction defect, ventricular arrhythmias, fibrosis, apoptosis, and premature death within 4 weeks. The phenotype is similar to LMNA-associated cardiomyopathy in humans. RNA sequencing, performed before the onset of cardiac dysfunction, led to identification of 2338 differentially expressed genes (DEGs) in Lmna-deleted cardiomyocytes. …

Prognostic Impact Of Cdkn2a/B Deletion, Tert Mutation, And Egfr Amplification On Histological And Molecular Idh-Wildtype Glioblastoma, Sirui Ma, Soumon Rudra, Jian L Campian, Sonika Dahiya, Gavin P Dunn, Tanner Johanns, Michael Goldstein, Albert H Kim, Jiayi Huang

2020-Current year OA Pubs

BACKGROUND: We aimed to evaluate the clinical outcomes of molecular glioblastoma (mGBM) as compared to histological GBM (hGBM) and to determine the prognostic impact of

METHODS: IDH-wildtype GBM patients treated with radiation therapy (RT) between 2012 and 2019 were retrospectively analyzed. mGBM was defined as grade II-III IDH-wildtype astrocytoma without histological features of GBM but with one of the following molecular alterations:

RESULTS: Of the 367 eligible patients, the median follow-up was 11.7 months. mGBM and hGBM did not have significantly different OS (median: 16.6 vs 13.5 months, respectively,

CONCLUSION: Criteria for mGBM may require further refinement and validation.

Early Diagnosis And Intervention In Cystic Fibrosis: Imagining The Unimaginable, Andrea M Coverstone, Thomas W Ferkol

Open Access Publications

Cystic fibrosis is the most common life-shortening genetic disease affecting Caucasians, clinically manifested by fat malabsorption, poor growth and nutrition, and recurrent sinopulmonary infections. Newborn screening programs for cystic fibrosis are now implemented throughout the United States and in many nations worldwide. Early diagnosis and interventions have led to improved clinical outcomes for people with cystic fibrosis. Newer cystic fibrosis transmembrane conductance regulator potentiators and correctors with mutation-specific effects have increasingly been used in children, and these agents are revolutionizing care. Indeed, it is possible that highly effective modulator therapy used early in life could profoundly affect the trajectory of …

Relationships Between Big-Five Personality Factors And Alzheimer's Disease Pathology In Autosomal Dominant Alzheimer's Disease, Andrew J Aschenbrenner, Jennifer Petros, Eric Mcdade, Guoqiao Wang, David A Balota, Tammie Ls Benzinger, Carlos Cruchaga, Chengjie Xiong, Richard Perrin, Anne M Fagan, John C Morris, Randall Bateman, Jason Hassenstab, Et Al

Open Access Publications

Introduction: Changes in personality characteristics are associated with the onset of symptoms in Alzheimer's disease (AD) and may even precede clinical diagnosis. However, personality changes caused by disease progression can be difficult to separate from changes that occur with normal aging. The Dominantly Inherited Alzheimer Network (DIAN) provides a unique cohort in which to relate measures of personality traits to in vivo markers of disease in a much younger sample than in typical late onset AD.

Methods: Personality traits measured with the International Personality Item Pool at baseline from DIAN participants were analyzed as a function of estimated years to …

Therapeutic Enhancement Of Blood-Brain And Blood-Tumor Barriers Permeability By Laser Interstitial Thermal Therapy, Afshin Salehi, Mounica R Paturu, Bhuvic Patel, Matthew D Cain, Tatenda Mahlokozera, Alicia B Yang, Tsen-Hsuan Lin, Eric C Leuthardt, Hiroko Yano, Sheng-Kwei Song, Robyn S Klein, Robert Schmidt, Albert H Kim

Open Access Publications

BACKGROUND: The blood-brain and blood-tumor barriers (BBB and BTB), which restrict the entry of most drugs into the brain and tumor, respectively, are a significant challenge in the treatment of glioblastoma. Laser interstitial thermal therapy (LITT) is a minimally invasive surgical technique increasingly used clinically for tumor cell ablation. Recent evidence suggests that LITT might locally disrupt BBB integrity, creating a potential therapeutic window of opportunity to deliver otherwise brain-impermeant agents.

METHODS: We established a LITT mouse model to test if laser therapy can increase BBB/BTB permeability in vivo. Mice underwent orthotopic glioblastoma tumor implantation followed by LITT in combination …

Defining And Conceptualizing Outcomes For De-Implementation: Key Distinctions From Implementation Outcomes, Beth Prusaczyk, Taren Swindle, Geoffrey Curran

Open Access Publications

BACKGROUND: Increasingly, scholars argue that de-implementation is a distinct concept from implementation; factors contributing to stopping a current practice might be distinct from those that encourage adoption of a new one. One such distinction is related to de-implementation

CONCEPTUALIZATION OF OUTCOMES: We conceptualize each of the outcomes from Proctor and colleagues' taxonomy of implementation outcomes for de-implementation research. First, we suggest key considerations for researchers assessing de-implementation outcomes, such as considering how the cultural or historical significance to the practice may impact de-implementation success and, as others have stated, the importance of the patient in driving healthcare overuse. Second, we …

Induction Of Wnt16 Via Peptide-Mrna Nanoparticle-Based Delivery Maintains Cartilage Homeostasis, Huimin Yan, Ying Hu, Antonina Akk, Muhammad Farooq Rai, Hua Pan, Samuel A Wickline, Christine T N Pham

Open Access Publications

Osteoarthritis (OA) is a progressive joint disease that causes significant disability and pain and for which there are limited treatment options. We posit that delivery of anabolic factors that protect and maintain cartilage homeostasis will halt or retard OA progression. We employ a peptide-based nanoplatform to deliver Wingless and the name Int-1 (WNT) 16 messenger RNA (mRNA) to human cartilage explants. The peptide forms a self-assembled nanocomplex of approximately 65 nm in size when incubated with WNT16 mRNA. The complex is further stabilized with hyaluronic acid (HA) for enhanced cellular uptake. Delivery of peptide-WNT16 mRNA nanocomplex to human cartilage explants …

The relationship of temperament and character with psychosis has not been previously investigated in Africa. The study was conducted in Kenya, and involved participants at clinical high-risk (CHR) for psychosis (

Aging And Efficacy Of Disease-Modifying Therapies In Multiple Sclerosis: A Meta-Analysis Of Clinical Trials, Yinan Zhang, Natalia Gonzalez Caldito, Afsaneh Shirani, Amber Salter, Gary Cutter, William Culpepper, Mitchell Wallin, Peter Kosa, Bibiana Bielekova, Fred Lublin, Olaf Stuve

2020-Current year OA Pubs

Background: Disease-modifying therapies (DMTs) for multiple sclerosis (MS) are approved for the treatment of disease activity and are effective in reducing relapses and new magnetic resonance imaging (MRI) lesions. However, disease activity generally subsides with time, and age-dependent changes in DMT efficacy are not well-established. We aimed to investigate whether age impacts the efficacy of DMTs in treating disease activity in patients with relapsing-remitting MS (RRMS).

Methods: DMT efficacy related to age was assessed through a meta-analysis of clinical trials that evaluated the efficacy of DMTs in RRMS patients as measured by reductions in the annualized relapse rate (ARR), new …

Dill Extract Induces Elastic Fiber Neosynthesis And Functional Improvement In The Ascending Aorta Of Aged Mice With Reversal Of Age-Dependent Cardiac Hypertrophy And Involvement Of Lysyl Oxidase-Like-1, Wassim Fhayli, Quentin Boëté, Nadjib Kihal, Valérie Cenizo, Pascal Sommer, Walter A Boyle, Marie-Paule Jacob, Gilles Faury

Open Access Publications

Elastic fibers (90% elastin, 10% fibrillin-rich microfibrils) are synthesized only in early life and adolescence mainly by the vascular smooth muscle cells through the cross-linking of its soluble precursor, tropoelastin. Elastic fibers endow the large elastic arteries with resilience and elasticity. Normal vascular aging is associated with arterial remodeling and stiffening, especially due to the end of production and degradation of elastic fibers, leading to altered cardiovascular function. Several pharmacological treatments stimulate the production of elastin and elastic fibers. In particular, dill extract (DE) has been demonstrated to stimulate elastin production in vitro in dermal equivalent models and in skin …

Tumor Infiltrating Neutrophils Are Enriched In Basal-Type Urothelial Bladder Cancer, Giulio Eugenio Mandelli, Francesco Missale, Debora Bresciani, Luisa Benerini Gatta, Patrizia Scapini, Elena Caveggion, Elisa Roca, Mattia Bugatti, Matilde Monti, Luca Cristinelli, Sandra Belotti, Claudio Simeone, Stefano Calza, Laura Melocchi, William Vermi

Open Access Publications

BACKGROUND: Urothelial bladder cancers (UBCs) are distinct in two main molecular subtypes, namely basal and luminal type. Subtypes are also diverse in term of immune contexture, providing a rationale for patient selection to immunotherapy.

METHODS: By digital microscopy analysis of a muscle-invasive BC (MIBC) cohort, we explored the density and clinical significance of CD66b

RESULTS: Basal type BC contained a significantly higher density of CD66b

CONCLUSIONS: TAN are recruited in basal type MIBC by pro-inflammatory CKs. This finding establishes a groundwork for a better understanding of the UBC immunity and its relevance.
