Division of Nephrology Faculty Papers

BACKGROUND: There have been several recent advances in the care of patients with chronic kidney disease (CKD), including the use of sodium glucose cotransporter 2 (SGLT2) inhibitors and selective mineralocorticoid receptor antagonists (MRAs). There are very few data reporting the outcomes of these treatments in real-world experience. The aim of this retrospective study is to report the effects of SGLT2 inhibitors, finerenone, and their combination in CKD patients in our community-based setting.

METHODS: Ninety-eight patients with CKD with an estimated glomerular filtration rate (eGFR) between 25 and 90 mL/min per 1.73 m² and a urine albumin-to-creatinine ratio (UACR) ≥ …

Neuroendocrine Gene Subsets Are Uniquely Dysregulated In Prostate Adenocarcinoma, Nicole M. Naranjo, Anne Kennedy, Anna Testa, Cecilia E. Verrillo, Adrian D. Altieri, Rhonda Kean, D. Craig Hooper, Jindan Yu, Jonathan Zhao, Oliver Abinader, Maxwell W. Pickles, Adam Hawkins, William Kevin Kelly, Ramkrishna Mitra, Lucia R. Languino

Department of Pharmacology, Physiology, and Cancer Biology Faculty Papers

Prostate cancer has heterogeneous growth patterns, and its prognosis is the poorest when it progresses to a neuroendocrine phenotype. Using bioinformatic analysis, we evaluated RNA expression of neuroendocrine genes in a panel of five different cancer types: prostate adenocarcinoma, breast cancer, kidney chromophobe, kidney renal clear cell carcinoma and kidney renal papillary cell carcinoma. Our results show that specific neuroendocrine genes are significantly dysregulated in these tumors, suggesting that they play an active role in cancer progression. Among others, synaptophysin (SYP), a conventional neuroendocrine marker, is upregulated in prostate adenocarcinoma (PRAD) and breast cancer (BRCA). Our analysis shows that SYP …

Innate And Adaptive Immune Responses That Control Lymph-Borne Viruses In The Draining Lymph Node, Carolina R. Melo-Silva, Luis J. Sigal

Department of Microbiology and Immunology Faculty Papers

The interstitial fluids in tissues are constantly drained into the lymph nodes (LNs) as lymph through afferent lymphatic vessels and from LNs into the blood through efferent lymphatics. LNs are strategically positioned and have the appropriate cellular composition to serve as sites of adaptive immune initiation against invading pathogens. However, for lymph-borne viruses, which disseminate from the entry site to other tissues through the lymphatic system, immune cells in the draining LN (dLN) also play critical roles in curbing systemic viral dissemination during primary and secondary infections. Lymph-borne viruses in tissues can be transported to dLNs as free virions in …

Ephrin-B2 Promotes Nociceptive Plasticity And Hyperalgesic Priming Through Ephb2-Mnk-Eif4e Signaling In Both Mice And Humans, Eric David, Muhammad Saad Yousuf, Hao-Ruei Mei, Ashita Jain, Sharada Krishnagiri, Hajira Elahi, Rupali Venkatesan, Kolluru Srikanth, Gregory Dussor, Matthew Dalva, Theodore Price

Department of Neuroscience Faculty Papers

Ephrin-B-EphB signaling can promote pain through ligand-receptor interactions between peripheral cells, like immune cells expressing ephrin-Bs, and EphB receptors expressed by DRG neurons. Previous studies have shown increased ephrin-B2 expression in peripheral tissues like synovium of rheumatoid and osteoarthritis patients, indicating the clinical significance of this signaling. The primary goal of this study was to understand how ephrin-B2 acts on mouse and human DRG neurons, which express EphB receptors, to promote pain and nociceptor plasticity. We hypothesized that ephrin-B2 would promote nociceptor plasticity and hyperalgesic priming through MNK-eIF4E signaling, a critical mechanism for nociceptive plasticity induced by growth factors, cytokines …

Altered Extracellular Matrix Correlates With An Immunosuppressive Tumor Microenvironment And Disease Progression In Younger Adults With Oral Cavity Squamous Cell Carcinoma, Leonard Estephan, Gaurav Kumar, Matthew Stewart, Raphael Banoub, Alban Linnenbach, Larry Harshyne, Ubaldo Martinez-Outshoorn, My Mahoney, Joseph Curry, Jennifer Johnson, Andrew South, Adam Luginbuhl

Kimmel Cancer Center Faculty Papers

INTRODUCTION: Oral cavity squamous cell carcinoma (OSCC) occurs most frequently in patients >60 years old with a history of tobacco and alcohol use. Epidemiological studies describe increased incidence of OSCC in younger adults (years). Despite its poor prognosis, knowledge of OSCC tumor microenvironment (TME) characteristics in younger adults is scarce and could help inform possible resistance to emerging treatment options.

METHODS: Patients with OSCC were evaluated using TCGA-HNSC (n=121) and a stage and subsite-matched institutional cohort (n=8) to identify differential gene expression focusing on the extracellular matrix (ECM) and epithelial-mesenchymal transition (EMT) processes in younger (≤45 years) vs. older adults …

Association Of Mildly Elevated Pulmonary Vascular Resistance With Major Cardiovascular Events In Pulmonary Hypertension And Chronic Kidney Disease: A Retrospective Cohort Analysis, Jose M. Martinez Manzano, Alexander Prendergast, Tara John, Raul Leguizamon, Ian Mclaren, Rasha Khan, Andrew Geller, Phuuwadith Wattanachayakul, John Malin, Simone A. Jarrett, Kevin Bryan Lo, Sadia Benzaquen, Christian Witzke

Einstein Health Papers

Pulmonary hypertension (PH) is associated with adverse outcomes in chronic kidney disease (CKD) patients. Our study suggests mildly elevated pulmonary vascular resistance ( > 2 to ≤ 3) is independently associated with major adverse cardiovascular events at 1-year follow-up. Early diagnosis of precapillary PH in CKD patients can potentially improve clinical outcomes.

The Mapk Homolog, Smk1, Promotes Assembly Of The Glucan Layer Of The Spore Wall In S. Cerevisiae, Julia Y. Lee-Soety, Gwendolyn Resch, Abhimannyu Rimal, Erica S. Johnson, Jonathan Benway, Edward Winter

Department of Biochemistry and Molecular Biology Faculty Papers

Smk1 is a MAPK homolog in the yeast Saccharomyces cerevisiae that controls the postmeiotic program of spore wall assembly. During this program, haploid cells are surrounded by a layer of mannan and then a layer of glucan. These inner layers of the spore wall resemble the vegetative cell wall. Next, the outer layers consisting of chitin/chitosan and then dityrosine are assembled. The outer layers are spore-specific and provide protection against environmental stressors. Smk1 is required for the proper assembly of spore walls. However, the protective properties of the outer layers have limited our understanding of how Smk1 controls this morphogenetic …

Males With Patellofemoral Pain Have Altered Movements During Step-Down And Single-Leg Squatting Tasks Compared To Asymptomatic Males: A Cross-Sectional Study, Lisa T. Hoglund, Amy H. Amabile, Thomas Alexander Hulcher

Department of Physical Therapy Faculty Papers

Background and Aims

Patellofemoral pain (PFP) is common in males, causing reduced physical activity and chronic pain. One proposed cause of PFP is aberrant biomechanics during tasks loading the patellofemoral joint. Consistent evidence exists for females with PFP, but it is uncertain if males with PFP have altered biomechanics. This study investigated the kinematics of males with PFP compared to pain-free males during forward step-down (StDn) and single-leg squat (SLSq).

Methods

A cross-sectional study including 40 males aged 20–39 years (28.28 ± 5.46) was conducted (20 PFP, 20 pain-free). Participants performed StDn and SLSq while motion was captured with a …

A Trna Modification Pattern That Facilitates Interpretation Of The Genetic Code, Isao Masuda, Ya-Ming Hou

Department of Biochemistry and Molecular Biology Faculty Papers

Interpretation of the genetic code from triplets of nucleotides to amino acids is fundamental to life. This interpretation is achieved by cellular tRNAs, each reading a triplet codon through its complementary anticodon (positions 34–36) while delivering the amino acid charged to its 3′-end. This amino acid is then incorporated into the growing polypeptide chain during protein synthesis on the ribosome. The quality and versatility of the interpretation is ensured not only by the codon-anticodon pairing, but also by the post-transcriptional modifications at positions 34 and 37 of each tRNA, corresponding to the wobble nucleotide at the first position of the …

Frontotemporal Dementia-Like Disease Progression Elicited By Seeded Aggregation And Spread Of Fus, Sonia Vazquez-Sanchez, Britt Tilkin, Fatima Gasset-Rosa, Sitao Zhang, Diana Piol, Melissa Mcalonis-Downes, Jonathan Artates, Noe Govea-Perez, Yana Verresen, Lin Guo, Don Cleveland, James Shorter, Sandrine Da Cruz

Department of Biochemistry and Molecular Biology Faculty Papers

RNA binding proteins have emerged as central players in the mechanisms of many neurodegenerative diseases. In particular, a proteinopathy of fused in sarcoma (FUS) is present in some instances of familial Amyotrophic lateral sclerosis (ALS) and about 10% of sporadic Frontotemporal lobar degeneration (FTLD). Here we establish that focal injection of sonicated human FUS fibrils into brains of mice in which ALS-linked mutant or wild-type human FUS replaces endogenous mouse FUS is sufficient to induce focal cytoplasmic mislocalization and aggregation of mutant and wild-type FUS which with time spreads to distal regions of the brain. Human FUS fibril-induced FUS aggregation …

Department of Surgery Faculty Papers

BACKGROUND: Hiatal hernia is a common surgical pathology. Such hernias can be found incidentally and patients may opt for an initial nonoperative approach though many will pursue surgery after symptom progression. Data on the effects of age on the outcomes of hiatal hernia repair may help inform this decision-making process.

METHODS: The TriNetX database was queried for all adult patients undergoing hiatal hernia repair from 2000 to 2023. Patients were divided into elective and emergent cohorts on the basis of diagnosis codes indicating obstruction or gangrene. Patients aged 80-89 were compared against those aged 65-79 in unadjusted analysis. Logistic regression …

Novel Human Recombinant N-Acetylgalactosamine-6-Sulfate Sulfatase Produced In A Glyco-Engineered Escherichia Coli Strain, Luisa N. Pimentel-Vera, Alexander Rodríguez-López, Angela J. Espejo-Mojica, Aura María Ramírez, Carolina Cardona, Luis H. Reyes, Shunji Tomatsu, Thapakorn Jaroentomeechai, Matthew P. Delisa, Oscar F. Sánchez, Carlos J. Alméciga-Díaz

Department of Pediatrics Faculty Papers

Mucopolysaccharidosis IVA (MPS IVA) is a lysosomal storage disease caused by mutations in the gene encoding the lysosomal enzyme N-acetylgalactosamine-6-sulfate sulfatase (GALNS), resulting in the accumulation of keratan sulfate (KS) and chondroitin-6-sulfate (C6S). Previously, it was reported the production of an active human recombinant GALNS (rGALNS) in E. coli BL21(DE3). However, this recombinant enzyme was not taken up by HEK293 cells or MPS IVA skin fibroblasts. Here, we leveraged a glyco-engineered E. coli strain to produce a recombinant human GALNS bearing the eukaryotic trimannosyl core N-glycan, Man3GlcNAc2 (rGALNSoptGly). The N-glycosylated GALNS was produced at 100 …

The Impact Of Mechanical Thrombectomy On The Blood-Brain Barrier In Patients With Acute Ischemic Stroke: A Non-Contrast Mr Imaging Study Using Dp-Pcasl And Noddi, Nikolaos Mouchtouris, Isaiah Ailes, Ki Chang, Adam Flanders, Feroze Mohamed, Stavropoula Tjoumakaris, Michael Gooch, Pascal Jabbour, Robert Rosenwasswer, Mahdi Alizadeh

Department of Neurosurgery Faculty Papers

Background and purpose: While mechanical thrombectomy (MT) achieves restoration of cerebral blood flow to the area at risk in patients with acute ischemic stroke (AIS), the influx of blood flow may exacerbate the blood-brain barrier (BBB) disruption and extravasation across the BBB, and it therefore remains unclear how reperfusion impacts the blood-brain barrier integrity. In this study, we use diffusion-prepared pseudocontinuous ASL (DP-pCASL) and Neurite Orientation Dispersion and Density Imaging (NODDI) sequence to measure the water exchange rate (k_w) in patients who underwent either MT or medical management and determine its impact on the brain tissue microstructure in …
