Angiogenin-Catalyzed Cleavage Within Trna Anticodon-Loops Identified By Cp-Rna-Seq, Megumi Shigematsu, Ryuma Matsubara, Justin Gumas, Takuya Kawamura, Yohei Kirino

Computational Medicine Center Faculty Papers

Angiogenin (Ang), an endoribonuclease belonging to the RNase A superfamily, cleaves the anticodon-loops of tRNAs to produce tRNA-half molecules. Although previous studies have demonstrated the involvement of Ang in the pathobiology of neurodegenerative disorders, the characterization of Ang-generated tRNA halves in neuronal cells remains limited. This is partly due to the technical limitations of standard RNA-seq methods, which cannot capture Ang-generated RNAs containing a 2',3'-cyclic phosphate (cP). In this report, we established an Ang-treatment model using SH-SY5Y, a human neuroblastoma cell line, and demonstrated Ang-dependent accumulation of tRNA halves. By performing cP-RNA-seq, which selectively captures cP-containing RNAs, we identified Ang-generated …

High Intracranial Pressure Following Endoscopic Third Ventriculostomy: Illustrative Case, Zachary Sokol, Rohan V. Gupta, Robert Ziechmann, Scott R. Shepard

Jefferson Hospital Staff Papers and Presentations

BACKGROUND: Endoscopic third ventriculostomy (ETV) is an effective procedure for the treatment of triventriculomegaly associated with aqueductal stenosis. However, some patients can develop severe and symptomatic intracranial pressure (ICP) elevations in the immediate postoperative period that can be monitored and treated with external ventricular drain (EVD) placement and controlled cerebrospinal fluid (CSF) diversion until the ICP normalizes and symptoms resolve.

OBSERVATIONS: The authors describe the case of a 39-year-old male who underwent ETV and intraoperative EVD placement for obstructive hydrocephalus associated with aqueductal stenosis. The patient was noted to have sustained ICP elevations in the immediate perioperative period but ultimately …

Christopher, Bernard Lopez, Wayne B. Lau, Walter Koch, Erhe Gao, Xin-Liang Ma, Yajing Wang

Department of Emergency Medicine Faculty Papers

BACKGROUND: Diabetes increases ischemic heart injury via incompletely understood mechanisms. We recently reported that diabetic adipocytes-derived small extracellular vesicles (sEV) exacerbate myocardial reperfusion (MI/R) injury by promoting cardiomyocyte apoptosis. Combining in vitro mechanistic investigation and in vivo proof-concept demonstration, we determined the underlying molecular mechanism responsible for diabetic sEV-induced cardiomyocyte apoptosis after MI/R.

METHODS AND RESULTS: Adult mice were fed a high-fat diet (HFD) for 12 weeks. sEV were isolated from plasma or epididymal adipose tissue. HFD significantly increased the number and size of plasma- and adipocyte-derived sEV. Intramyocardial injection of an equal number of diabetic plasma sEV in nondiabetic …

The activation of IP3 receptor (IP3R) Ca2+ channels generates agonist-mediated Ca2+ signals that are critical for the regulation of a wide range of biological processes. It is therefore surprising that CRISPR induced loss of all three IP3R isoforms (TKO) in HEK293 and HeLa cell lines yields cells that can survive, grow and divide, albeit more slowly than wild-type cells. In an effort to understand the adaptive mechanisms involved, we have examined the activity of key Ca2+ dependent transcription factors (NFAT, CREB and AP-1) and signaling pathways using luciferase-reporter assays, phosphoprotein immunoblots and whole genome transcriptomic studies. In addition, the diacylglycerol …

Virtual Primary Care In A Large Delaware-Based Independent Academic Medical Center: Impact And Opportunity, Darrell C. Dow, Sarah E. Schenck, Tracy L. Bell, Stephanie C. Roth, Omar Khan

Department of Family & Community Medicine Faculty Papers

COVID-19 and related challenges to patient access necessitated the development of new models of care to ensure a healthy patient population. This paper describes the outcomes of a pilot virtual primary care program at a large independent academic health center in Delaware. The preliminary results are encouraging from the perspective of provider and patient satisfaction, as well as the utility of the operational model. A complete cost-benefit analysis was beyond the scope of the paper; thus, future operational research should focus on the metrics of cost and quality as key indicators of model sustainability.

Center for Translational Medicine Faculty Papers

The study of the senile osteoporosis in men still lags significantly behind that in women. The changes of protein molecule levels and their relationships with bone loss remain poorly understood. In the present study, we used C57BL/6J male mice at ages from 3 to 24 mo to delineate the mechanisms of aging effects on bone loss. We used the microcomputed tomography, mechanical testing, histomorphometry assays, and detection of serum levels of undercarboxylated osteocalcin (ucOcn) and carboxylated osteocalcin (cOcn) to assess bone mass changes and their relationships with the ratios of ucOcn-to-cOcn in mice from different age groups. The results showed …

What Is The Evidence? Updates In The Use Of Antenatal Corticosteroids For Patients At Risk Of Preterm Birth, Moti Gulersen, Cynthia Gyamfi-Bannerman

Department of Obstetrics and Gynecology Faculty Papers

Antenatal corticosteroids have long been considered one of the most important antenatal therapies available for pregnant patients at risk of preterm birth based on the associated reduction of neonatal morbidity and mortality following their administration. However, despite decades of research since their incorporation into routine clinical practice, a number of key questions related to antenatal corticosteroid use remain. These include evaluating the impact of antenatal corticosteroids at gestational ages outside of the previously recommended window of 24 0/7–33 6/7 weeks of gestation, determining factors associated with optimal steroid timing in order to reduce unnecessary exposure, alterations in its dosing regimen, …

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

UNLABELLED: Inorganic polyphosphate (polyP) is an evolutionary and ancient polymer composed by orthophosphate units linked by phosphoanhydride bonds. In mammalian cells, polyP shows a high localization in mammalian mitochondria, and its regulatory role in various aspects of bioenergetics has already been demonstrated, via molecular mechanism(s) yet to be fully elucidated. In recent years, a role for polyP in signal transduction, from brain physiology to the bloodstream, has also emerged.

OBJECTIVE: In this manuscript, we explored the intriguing possibility that the effects of polyP on signal transduction could be mechanistically linked to those exerted on bioenergetics.

METHODS: To conduct our studies, …

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

Optic atrophy protein 1 (OPA1) mediates inner mitochondrial membrane (IMM) fusion and cristae organization. Mutations in OPA1 cause autosomal dominant optic atrophy (ADOA), a leading cause of blindness. Cells from ADOA patients show impaired mitochondrial fusion, cristae structure, bioenergetic function, and mitochondrial DNA (mtDNA) integrity. The mtDNA encodes electron transport chain subunits and is packaged into nucleoids spread within the mitochondrial population. Nucleoids interact with the IMM, and their distribution is tightly linked to mitochondrial fusion and cristae shaping. Yet, little is known about the physio-pathological relevance of nucleoid distribution. We studied the effect of OPA1 and ADOA-associated mutants on …


Akt Kinases As Therapeutic Targets, Dalal Hassan, Craig Menges, Joseph Testa, Alfonso Bellacosa Nov 2024

Akt Kinases As Therapeutic Targets, Dalal Hassan, Craig Menges, Joseph Testa, Alfonso Bellacosa

Student Papers, Posters & Projects

AKT, or protein kinase B, is a central node of the PI3K signaling pathway that is pivotal for a range of normal cellular physiologies that also underlie several pathological conditions, including inflammatory and autoimmune diseases, overgrowth syndromes, and neoplastic transformation. These pathologies, notably cancer, arise if either the activity of AKT or its positive or negative upstream or downstream regulators or effectors goes unchecked, superimposed on by its intersection with a slew of other pathways. Targeting the PI3K/AKT pathway is, therefore, a prudent countermeasure. AKT inhibitors have been tested in many clinical trials, primarily in combination with other drugs. While …

Einstein Health Papers

Background: Kidney Transplant Recipients (KTRs) are at risk of renal cell carcinoma (RCC). The risk of RCC in KTRs is approximated to be 5–10 times higher compared with the general population. A relation between kidney rejection and renal malignancy has been described and relates to the effect of immunosuppression at the genomic level. We decided to investigate any suggestive clinical evidence of this in the OPTN database. Methods: KTRs with de novo RCC between July 2004 and June 2022 were identified. Demographics, baseline characteristics, virology, and immunology data were compared between patients with and without RCC. Our follow-up period was …

Department of Radiation Oncology Faculty Papers

Background: Glioma is a primary malignant brain tumor with a poor prognosis. Glioma-related biomarkers need to be identified to enable the personalized treatment of and predict the prognosis of glioma patients. Cuproptosis is an unusual mechanism of cell death, and is closely associated with disease progression and the immune-microenvironment of the tumor. However, the function of cuproptosis in glioma is still unclear, therefore the aim of this study was to investigate the role of cuproptosis-related genes in gliomas.

Methods: We examined the relationship between cuproptosis and glioma using the clinical and expression data of glioma tumors from The Cancer Genome …
