The Role Of Decorin Proteoglycan In Mitophagy., Thomas Neill, Renato V. Iozzo

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

Proteoglycans are emerging as critical regulators of intracellular catabolism. This rise in prominence has transformed our basic understanding and alerted us to the existence of non-canonical pathways, independent of nutrient deprivation, that potently control the autophagy downstream of a cell surface receptor. As a member of the small leucine-rich proteoglycan gene family, decorin has single-handedly pioneered the connection between extracellular matrix signaling and autophagy regulation. Soluble decorin evokes protracted endothelial cell autophagy via Peg3 and breast carcinoma cell mitophagy via mitostatin by interacting with VEGFR2 or the MET receptor tyrosine kinase, respectively. In this paper, we give a mechanistic perspective …

Mir-196a Upregulation Contributes To Gefitinib Resistance Through Inhibiting Gltp Expression, Bing-Jie Liu, Fang-Fang Li, Yun-Xia Xie, Chong-Yuan Fan, Wen-Jing Liu, Jian-Ge Qiu, Bing-Hua Jiang

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

Tyrosine kinase inhibitor (TKI) therapy has greatly improved lung cancer survival in patients with epidermal growth factor receptor (EGFR) mutations. However, the development of TKI-acquired resistance is the major problem to be overcome. In this study, we found that miR-196a expression was greatly induced in gefitinib-resistant lung cancer cells. To understand the role and mechanism of miR-196a in TKI resistance, we found that miR-196a-forced expression alone increased cell resistance to gefitinib treatment in vitro and in vivo by inducing cell proliferation and inhibiting cell apoptosis. We identified the transcription factor nuclear factor erythroid 2-related factor 2 (NRF2) bound to the …

Division of Cardiology Faculty Papers

The patient is a 73-year-old female with peripheral vascular disease, coronary artery disease, and systemic lupus erythematosus, who underwent mesenteric artery bypass surgery. She suffered from a pneumonia after surgery, causing acute hypoxic respiratory failure and septic shock. Due to shock, she developed acute renal failure. She was intubated, ventilated, and received continuous veno-venous hemodialysis for renal failure. ST elevation was first observed on telemetry and subsequently confirmed on electrocardiogram. Marked ST elevation is present in the anterior leads with reciprocal ST depression in the inferior leads. A prolonged QT interval is also present. What is the most likely diagnosis?

Abcc6 Null Mice-A Model For Mineralization Disorder Pxe Shows Vertebral Osteopenia Without Enhanced Intervertebral Disc Calcification With Aging, Paige K Boneski, Vedavathi Madhu, Ryan Tomlinson, Irving Shapiro, Koen Van De Wetering, Makarand V Risbud

Department of Orthopaedic Surgery Faculty Papers

Chronic low back pain is a highly prevalent health condition intricately linked to intervertebral disc degeneration. One of the prominent features of disc degeneration that is commonly observed with aging is dystrophic calcification. ATP-binding cassette sub-family C member 6 (ABCC6), a presumed ATP efflux transporter, is a key regulator of systemic levels of the mineralization inhibitor pyrophosphate (PPi). Mutations in ABCC6 result in pseudoxanthoma elasticum (PXE), a progressive human metabolic disorder characterized by mineralization of the skin and elastic tissues. The implications of ABCC6 loss-of-function on pathological mineralization of structures in the spine, however, are unknown. Using the Abcc6 -/- …

Department of Medical Oncology Faculty Papers

Background: Older adults (≥65 years) with gastrointestinal (GI) cancers who receive chemotherapy are at increased risk of hospitalization caused by treatment-related toxicity. Geriatric assessment (GA) has been previously shown to predict risk of toxicity in older adults undergoing chemotherapy. However, studies incorporating the GA specifically in older adults with GI cancers have been limited. This study sought to identify GA-based risk factors for chemotherapy toxicity-related hospitalization among older adults with GI cancers.

Patients and methods: We performed a secondary post hoc subgroup analysis of two prospective studies used to develop and validate a GA-based chemotherapy toxicity score. The incidence of …

Positive Selection And Enhancer Evolution Shaped Lifespan And Body Mass In Great Apes, Daniela Tejada-Martinez, Roberto A Avelar, Inês Lopes, Bruce Zhang, Guy Novoa, João Pedro De Magalhães, Marco Trizzino

Department of Biochemistry and Molecular Biology Faculty Papers

Within primates, the great apes are outliers both in terms of body size and lifespan, since they include the largest and longest-lived species in the order. Yet, the molecular bases underlying such features are poorly understood. Here, we leveraged an integrated approach to investigate multiple sources of molecular variation across primates, focusing on over 10,000 genes, including approximately 1,500 previously associated with lifespan, and additional approximately 9,000 for which an association with longevity has never been suggested. We analyzed dN/dS rates, positive selection, gene expression (RNA-seq), and gene regulation (ChIP-seq). By analyzing the correlation between dN/dS, maximum lifespan, and body …

Liquid-Liquid Phase Separation Of Tdp-43 And Fus In Physiology And Pathology Of Neurodegenerative Diseases, Jenny L Carey, Lin Guo

Department of Biochemistry and Molecular Biology Faculty Papers

Liquid-liquid phase separation of RNA-binding proteins mediates the formation of numerous membraneless organelles with essential cellular function. However, aberrant phase transition of these proteins leads to the formation of insoluble protein aggregates, which are pathological hallmarks of neurodegenerative diseases including ALS and FTD. TDP-43 and FUS are two such RNA-binding proteins that mislocalize and aggregate in patients of ALS and FTD. They have similar domain structures that provide multivalent interactions driving their phase separation in vitro and in the cellular environment. In this article, we review the factors that mediate and regulate phase separation of TDP-43 and FUS. We also …

Innovations In Cervical Spine Trauma: Developing The Next Generation Upper Cervical Spine Injury Classification System, Brian A Karamian, Hannah Levy, Paul D. Minetos, Michael L. Smith, Alex R. Vaccaro

Rothman Institute Papers

The upper cervical spine not only consists of intricate bony and ligamentous anatomy affording unique flexibility but also has increased susceptibility to injuries. The upper cervical spine trauma can result in a wide spectrum of injuries that can be managed both operatively and nonoperatively. Several existing classification systems have been proposed to describe injuries of the upper cervical spine, many of which rely on anatomic descriptions of injury location. Prior fracture classifications are limited in scope, characterizing fractures restricted to a single region of the upper cervical spine, and fail to provide insight into injury management. The AO Spine Upper …

Ras-Mediated Tumor Stress Adaptation And The Targeting Opportunities It Presents, Alexandra Redding, A E Aplin, Elda Grabocka

Department of Cancer Biology Faculty Papers

Cellular stress is known to function in synergistic cooperation with oncogenic mutations during tumorigenesis to drive cancer progression. Oncogenic RAS is a strong inducer of a variety of pro-tumorigenic cellular stresses, and also enhances the ability of cells to tolerate these stresses through multiple mechanisms. Many of these oncogenic, RAS-driven, stress-adaptive mechanisms have also been implicated in tolerance and resistance to chemotherapy and to therapies that target the RAS pathway. Understanding how oncogenic RAS shapes cellular stress adaptation and how this functions in drug resistance is of vital importance for identifying new therapeutic targets and therapeutic combinations to treat RAS-driven …

Early Morphological Changes Of The Rectus Femoris Muscle And Deep Fascia In Ullrich Congenital Muscular Dystrophy, Patrizia Sabatelli, Luciano Merlini, Alberto Di Martino, Vittoria Cenni, Cesare Faldini

Department of Medicine Faculty Papers

Ullrich congenital muscular dystrophy (UCMD) is a severe form of muscular dystrophy caused by the loss of function of collagen VI, a critical component of the muscle-tendon matrix. Magnetic resonance imaging of UCMD patients’ muscles shows a peculiar rim of abnormal signal at the periphery of each muscle, and a relative sparing of the internal part. The mechanism/s involved in the early fat substitution of muscle fiber at the periphery of muscles remain elusive. We studied a muscle biopsy of the rectus femoris/deep fascia (DF) of a 3-year-old UCMD patient, with a homozygous mutation in the COL6A2 gene. By immunohistochemical …

Targeting Gastrointestinal Cancers With Chimeric Antigen Receptor (Car)-T Cell Therapy, Ross E Staudt, Robert D Carlson, Adam E. Snook

Department of Pharmacology and Experimental Therapeutics Faculty Papers

The immune system is capable of remarkably potent and specific efficacy against infectious diseases. For decades, investigators sought to leverage those characteristics to create immune-based therapies (immunotherapy) that might be far more effective and less toxic than conventional chemotherapy and radiation therapy for cancer. Those studies revealed many factors and mechanisms underlying the success or failure of cancer immunotherapy, leading to synthetic biology approaches, including CAR-T cell therapy. In this approach, patient T cells are genetically modified to express a chimeric antigen receptor (CAR) that converts T cells of any specificity into tumor-specific T cells that can be expanded to …

Diagnosing Vitreoretinal Lymphomas—An Analysis Of The Sensitivity Of Existing Tools, Anahita Sehgal, Jose S. Pulido, Arman Mashayekhi, Tatyana Milman, Gabor Gy Deák

Wills Eye Hospital Papers

Vitreoretinal Lymphoma (VRL) is a rare ocular pathology that is notorious for mimicking chronic uveitis, which is a seemingly benign condition in comparison. The most common form of VRL is the diffuse large B-cell type, and there has been a high mortality rate. This dismal prognosis can be improved significantly if the disease is diagnosed early, but until now there is no consensus on an appropriate diagnostic algorithm. We conducted a retrospective search of PubMed Central® and analyzed results from thirty-three studies that were published between 2011–2021. The chosen studies incorporated some popular testing tools for VRL, and our analyses …
