This study compares myocardial injury responses in human donor hearts from donation after brain death (DBD) and donation after circulatory death (DCD), with a focus on myocardial membrane integrity, pyroptosis, and damage. Unlike DCD hearts, which are exposed to varying durations of functional warm ischemic time (fWIT), DBD hearts, which are never subjected to warm ischemia, served as controls. A total of 24 human hearts were procured, consisting of 6 from the DBD group and 18 from the DCD group. All procured hearts were placed in cold normal saline and stored for up to 6 h. Left ventricular biopsies were …

WNT4 is a secreted protein that plays a critical role in the regulation of cell fate and embryogenesis. Biallelic variants in WNT4 have been linked to SERKAL syndrome, an autosomal recessive disorder characterized by 46,XX sex reversal and dysgenesis of the kidneys, adrenals, and lungs. SERKAL syndrome has only been described in a single consanguineous kindred with four affected fetuses. Additional features seen in a subset of affected fetuses included ventricular septal defect (VSD), congenital diaphragmatic hernia (CDH), and orofacial clefting (OFC). To determine if these additional features were likely to be caused by WNT4 deficiency, we used machine learning …

Effective obesity management in the Smith-Magenis syndrome (SMS) population has multiple inherent barriers related to their cognitive impairments, anxiety, behavioral disturbances, and sleep disorders. However, to date, no research exists related to strategies caregivers successfully employ to help individuals with SMS manage their food intake and mitigate associated behaviors.

Methods: We performed a qualitative thematic analysis of group interviews from 23 caregivers representing 21 individuals with SMS. Hybrid thematic analysis revealed that successful strategies employed by caregivers in this unique population revolved around a global theme of Empowering Through …

Amino Acids And Lean Mass Accretion In Preterm Neonates, Antonio C Ramos Dos Santos, Marta L Fiorotto, Teresa A Davis

Faculty, Staff and Students Publications

Purpose of review: This review evaluates recent evidence on how total protein and energy intake, amino acid composition, and nutrient delivery modality influence protein synthesis in preterm neonates, with the goal of informing nutritional strategies to support optimal lean mass accretion and growth.

Recent findings: Preterm neonates exhibit anabolic resistance to feeding due to impaired insulin and amino acid signaling in skeletal muscle. Enteral nutrition, especially fortified human milk, supports better lean mass accretion and neurodevelopment than parenteral nutrition. Intermittent bolus feeding and pulsatile leucine supplementation during continuous feeding further enhance mTORC1-dependent translation initiation signaling and protein synthesis efficiency in …

Unraveling Posttranslational Modification Complexity: Advances In Quantitative Histone Proteoform Mass Spectrometry, Karl F Poncha, Alyssa T Paparella, Nicolas L Young

Faculty, Staff and Students Publications

Histone proteins and their posttranslational modifications are central to chromatin structure and function. These modifications often occur in combinations, generating a diverse array of histone proteoforms that contribute to the dynamic regulation of chromatin architecture. Advancements in mass spectrometry-based proteomics, particularly top-down and middle-down approaches, have significantly enhanced our ability to characterize these proteoforms and elucidate PTM crosstalk. This review provides an analysis of the epigenetic machinery involved in the addition, recognition, and removal of histone PTMs, emphasizing the complexity introduced by histone variants and combinatorial PTM patterns. We examine the challenges and limitations of traditional antibody-based methods for PTM …

Platelet Extravasation In The Microvasculature: An Under-Appreciated Role For Platelets, Justin A Courson, Vahid Afshar-Kharghan, Alan R Burns, Rolando E Rumbaut

Faculty, Staff and Students Publications

In recent years, evidence has accumulated highlighting the presence and role of platelet extravasation - wherein platelets accumulate in tissue parenchyma - at a variety of sites throughout the body. While platelets are traditionally known for their roles in hemostasis and thrombosis, it is evident that platelets are potent mediators of inflammation across an array of physiological and pathological contexts. While anucleate and small in size, platelets contain a rich diversity of molecules in their granules capable of modulating cell proliferation, tissue repair, and a host of immune responses. There is growing evidence that platelet extravasation out of the vascular …

Faculty, Staff and Students Publications

Idiopathic pulmonary fibrosis (IPF) is a chronic, progressive interstitial pneumonia of unknown etiology. Its pathogenesis involves complex multicellular interactions and signaling pathways, with fibroblast-to-myofibroblast transition (FMT) being critical for fibrogenesis. Although the transcription factor Y-box binding protein 1 (YBX1) regulates processes such as cell proliferation, transcription, translation, and DNA repair, its role in IPF remains undefined. Here, we demonstrate that YBX1 overexpression significantly promotes transforming growth factor-β1 (TGF-β1)-induced pulmonary FMT, leading to substantially increased extracellular matrix (ECM) deposition in primary human (PHLFs) and mouse (PMLFs) lung fibroblasts. Conversely, YBX1 inhibition markedly suppresses TGF-β1-driven aberrant fibroblast migration and activation. Mechanistically, YBX1 …

Left Atrial Appendage Closure Devices: A Contemporary Review Of Techniques, Tips And Tricks, Kamran Namjouyan, Hafeez Ul Hassan Virk, Affan Rizwan, Muzamil Khawaja, Mahboob Alam, Markus Strauss, Chayakrit Krittanawong

Faculty, Staff and Students Publications

Atrial fibrillation (AF) affects approximately 3%-5% of adults and is projected to double in prevalence by 2060, significantly increasing the burden of thromboembolic stroke. This risk is largely attributed to thrombus formation within the left atrial appendage (LAA), particularly in nonvalvular AF, where the LAA's trabeculated anatomy, diverse morphologies (e.g., chicken wing, windsock, cactus, cauliflower), and impaired contractility allows for blood stasis and thrombogenesis. As a result, the LAA has become a focus for stroke prevention strategies. This review demonstrates current evidence on LAA closure by discussing patient selection, anatomical feasibility, procedural workflow, imaging guidance (transesophageal echocardiography vs. intracardiac echocardiography), …

Faculty, Staff and Students Publications

Obesity has long been identified as a noteworthy risk factor for cardiovascular diseases, including aortic stenosis. Nevertheless, an unexplained phenomenon known as the obesity paradox has arisen in the context of transcatheter aortic valve implantation (TAVI), inquiring conventional beliefs. The obesity paradox refers to better clinical outcomes observed in obese individuals undergoing TAVI. These include reduced all-cause mortality, lower rates of procedural complications, and improved long-term survival rates compared to their lean counterparts. Several theories have been proposed to explain the obesity paradox in TAVI. One of the most popular is the adipose tissue-mediated cardioprotective effect hypothesis. It is known …

Differences In Gene Expression May Contribute To The Racial Differences In The Risk Of Masld, Ivan P Gorlov, Olga Y Gorlova, Aaron P Thrift

Faculty, Staff and Students Publications

Metabolic dysfunction-associated steatotic liver disease (MASLD), formerly known as non-alcoholic fatty liver disease (NAFLD), exhibits marked racial disparities in incidence, progression, and clinical outcomes. While diet, lifestyle, and socioeconomic factors have been shown to influence these disparities, biological mechanisms underlying racial differences in MASLD risk remain poorly understood. We hypothesized that race-associated variation in hepatic gene expression may contribute to differential susceptibility and progression of MASLD. To test this hypothesis, we analyzed publicly available gene expression data from liver biopsies obtained from over 300 Black and White individuals undergoing bariatric surgery. Gene expression profiles were compared across four histological stages: …

ARv7, the most prevalent androgen receptor (AR) variant in castration-resistant prostate cancer, lacks the ligand binding domain (LBD), rendering it resistant to LBD-targeted therapies. Identifying new therapeutic targets requires defining the coregulators and associated regulatory enzymes that govern AR and ARv7 transcriptional activity. Here, we have developed a cell-free DNA pulldown assay employing androgen response elements (AREs) to isolate and characterize the AR- and ARv7-associated coregulator complexes formed on DNA. Mass spectrometry analyses of ARE DNA pulldowns revealed previously unrecognized AR and ARv7 associating coregulators, such as cullin-associated NEDD8-dissociated protein 1 (CAND1), in addition to previously known coregulators. ARv7 showed …

T cell therapy has proven challenging for pancreatic ductal adenocarcinoma (PDAC), partly due to heterogeneous expression of tumor-associated antigens (TAAs). To address tumor heterogeneity and mitigate immune evasion, an ex vivo expanded, polyclonal, T helper 1 cell-polarized T cell product targeting five TAAs—PRAME, SSX2, MAGEA4, Survivin and NY-ESO-1—was developed. These antigens were chosen based on their tumor specificity, oncogenicity, immunogenicity and level of expression. In a phase 1/2 trial, this autologous nonengineered T cell product was administered (1 × 107 cells m−2 per infusion) monthly to patients with advanced PDAC responding (arm A, n = 13) or refractory (arm B, …
