Although pathological complete response (pCR) and major pathological response (MPR) rates of neoadjuvant immunotherapy combined with chemotherapy in head and neck squamous cell carcinoma (HNSCC) trials remain suboptimal, emerging evidence highlights the synergistic potential of combining low-dose radiotherapy with immunotherapy to promote the efficacy of immunotherapy. This phase II, open-label, single-arm, multicenter trial (NCT05343325) enrolled 28 patients with untreated stage III-IVB HNSCC (NeoRTPC02). Patients received neoadjuvant low-dose radiotherapy, the programmed death-1 (PD-1) inhibitor tislelizumab, albumin-bound paclitaxel, and cisplatin for two cycles, followed by radical resection ~4 weeks after treatment completion. The primary endpoint, pCR rate, was achieved in 14 of …

Science Tikkun: A Bioscience Pandemic Framework In A Hebrew Tradition Of Global Repair, Peter Hotez

Center for Medical Ethics and Health Policy Staff Publications

Over the past decade we have seen a steady increase in dangerous pandemic threats. They include two major Ebola epidemics and cholera in Africa; dengue, Zika, yellow fever in the Americas; a COVID-19 pandemic; and H5N1 in Texas. This is happening because of a confluence of modern forces including urbanization, deforestation, and climate change. Yet as pandemics emerge on a crowded and warming planet, anti-science disinformation and antisemitism impede our response. Science tikkun is an overarching framework for repair and redress. It honors the legacy of Maimonides, Teilhard de Chardin, and others who have sought reconciliation between science and religion.

St6galnac-I Regulates Tumor Cell Sialylation Via Nectin2/Muc5ac-Mediated Immunosuppression And Angiogenesis In Non-Small Cell Lung Cancer, Muthamil Iniyan Appadurai, Sanjib Chaudhary, Ashu Shah, Gopalakrishnan Natarajan, Zahraa W. Alsafwani, Parvez Khan, Dhananjay D. Shinde, Subodh M. Lele, Lynette M. Smith, Mohd W. Nasser, Surinder K. Batra, Apar Kishor Ganti, Imayavaramban Lakshmanan

Journal Articles: Biochemistry & Molecular Biology

Glycosylation controls immune evasion, tumor progression, and metastasis. However, how tumor cell sialylation regulates immune evasion remains poorly characterized. ST6GalNAc-I, a sialyltransferase that conjugates sialic acid to the glycans in glycoproteins, was overexpressed in an aggressive-type KPA (KrasG12D/+ Trp53R172H/+ Ad-Cre) lung adenocarcinoma (LUAD) model and patient samples. Proteomic and biochemical analysis indicated that ST6GalNAc-I mediated NECTIN2 sialylation in LUAD cells. ST6GalNAc-I-deficient tumor cells cocultured with T cells were more susceptible to T cell-mediated tumor cell killing, indicating a key role for NECTIN2 in T cell dysfunction. Mice injected with St6galnac-I-knockdown syngeneic cells showed reduced lung tumor incidence and Nectin2/Tigit-associated immunosuppression. …

Acute Kidney Injury Triggers Hypoxemia By Lung Intravascular Neutrophil Retention That Reduces Capillary Blood Flow, Yohei Komaru, Liang Ning, Carine Lama, Anusha Suresh, Eirini Kefaloyianni, Mark J. Miller, Shinichi Kawana, Hailey M Shepherd, Wenjun Li, Daniel Kreisel, Andreas Herrlich

2020-Current year OA Pubs

Sterile acute kidney injury (AKI) is common in the clinic and frequently associated with unexplained hypoxemia that does not improve with dialysis. AKI induces remote lung inflammation with neutrophil recruitment in mice and humans, but which cellular cues establish neutrophilic inflammation and how it contributes to hypoxemia is not known. Here we report that AKI induced rapid intravascular neutrophil retention in lung alveolar capillaries without extravasation into tissue or alveoli, causing hypoxemia by reducing lung capillary blood flow in the absence of substantial lung interstitial or alveolar edema. In contrast to direct ischemic lung injury, lung neutrophil recruitment during remote …

2020-Current year OA Pubs

Kidney disease, the ninth leading cause of death in the United States, suffers from poor diagnostic efficiency (10%). Traditional biopsies use molecular reagents to enhance diagnostic power but are limited by overlapping spatial and chromatic signals, product quality variability, and additional processing. To address these challenges without disrupting routine diagnostics, we implement label-free imaging modalities-stimulated Raman scattering (SRS), second harmonic generation (SHG), and two-photon fluorescence (TPF)-within a single setup. We identify morphological, lipidomic, and metabolic biomarkers in control and diabetic kidney samples at subcellular resolution. Label-free Stimulated Raman Histology (SRH) reveals distinct collagen morphology, mesangial-glomerular volumes, lipid saturation, redox status, …

Network Analysis Of The Cerebrospinal Fluid Proteome Reveals Shared And Unique Differences Between Sporadic And Familial Forms Of Amyotrophic Lateral Sclerosis, Adam N Trautwig, Cindy V Ly, Timothy M Miller, Et Al.

2020-Current year OA Pubs

BACKGROUND: Amyotrophic Lateral Sclerosis (ALS), a neurodegenerative disease involving loss of motor neurons, typically results in death within 3-5 years of disease onset. Although roughly 10% of cases can be linked to a specific inherited mutation (e.g., C9orf72 hexanucleotide repeat expansion or SOD1 mutation), the cause(s) of most cases are unknown. Consequently, there is a critical need for biomarkers that reflect disease onset and progression across ALS subgroups.

METHODS: We employed tandem mass tag mass spectrometry (TMT-MS) based proteomics on cerebrospinal fluid (CSF) to identify and quantify 2105 proteins from sporadic, C9orf72, and SOD1 ALS patients, asymptomatic C9orf72 expansion carriers, …

A Phase I Dose-Escalation Study Of The Hif-2 Alpha Inhibitor Dff332 In Patients With Advanced Clear-Cell Renal Cell Carcinoma, Sumanta K Pal, Joel Picus, Et Al.

2020-Current year OA Pubs

PURPOSE: Mutations or silencing of the von Hippel-Lindau tumor suppressor gene accumulate hypoxia-inducible factors (HIF). HIF-2α is implicated in the oncogenesis of ∼50% of patients with clear-cell renal cell carcinoma (ccRCC) but has been considered "undruggable." DFF332, an orally administered novel allosteric inhibitor of HIF-2α, showed dose-dependent antitumor efficacy in preclinical models of ccRCC.

PATIENTS AND METHODS: This first-in-human study evaluated the safety, tolerability, antitumor activity, pharmacokinetics, and pharmacodynamics of DFF332 in patients with heavily pretreated advanced ccRCC. Preliminary data from the dose escalation of DFF332 monotherapy, administered orally at 50 or 100 mg weekly or 25, 50, 100, or …

Altered protein homeostasis through proteasomal degradation of ubiquitinated proteins is a hallmark of many cancers. Ubiquitination, coordinated by E1, E2, and E3 enzymes, involves up to 40 E2-conjugating enzymes in humans to specify substrates and ubiquitin linkages. In a screen for E2 dependencies in acute myeloid leukemia (AML), ubiquitin conjugating enzyme E2 N (UBE2N) emerged as the top candidate. To investigate UBE2N's role in AML, we characterized an enzymatically defective mouse model of UBE2N, revealing UBE2N's requirement in AML without an impact on normal hematopoiesis. Unlike other E2s, which mediate lysine-48 (K48) polyubiquitination and degradation of proteins, UBE2N primarily synthesizes …

Neoadjuvant immunotherapy can induce pathologic complete response (pCR) in patients with localized deficient mismatch repair (dMMR)/microsatellite instability-high (MSI-H) tumors. The long-term outcomes of these patients are unknown, as is the clinical utility of measuring circulating tumor DNA (ctDNA). Follow-up was evaluated in patients enrolled in a phase II trial (NCT04082572) that evaluated the efficacy and safety of pembrolizumab in patients with localized dMMR/MSI-H tumors. The primary outcomes of this trial have previously been reported. 3-year EFS and OS rates were 80% (95% CI: 66% - 93%) and 94% (95% CI: 86% - 100%). Patients without detectable ctDNA after pembrolizumab had …

Department of Biochemistry and Molecular Biology Faculty Papers

FAN1 is a DNA dependent nuclease whose proper function is essential for maintaining human health. For example, a genetic variant in FAN1, Arg507 to His hastens onset of Huntington's disease, a repeat expansion disorder for which there is no cure. How the Arg507His mutation affects FAN1 structure and enzymatic function is unknown. Using cryo-EM and biochemistry, we have discovered that FAN1 arginine 507 is critical for its interaction with PCNA, and mutation of Arg507 to His attenuates assembly of the FAN1-PCNA complex on a disease-relevant extrahelical DNA extrusions formed within DNA repeats. This mutation concomitantly abolishes PCNA-FAN1-dependent cleavage of such …

Incorporating Latent Survival Trajectories And Covariate Heterogeneity In Time-To-Event Data Analysis: A Joint Mixture Model Approach

Faculty, Staff and Student Publications

Background: Finite mixture models have been recently applied in time-to-event data to identify subgroups with distinct hazard functions, yet they often assume differing covariate effects on failure times across latent classes but homogeneous covariate distributions. This study aimed to develop a method for analyzing time-to-event data while accounting for unobserved heterogeneity within a mixture modeling framework.

Methods: A joint model was developed to incorporate latent survival trajectories and observed information for the joint analysis of time-to-event outcomes, correlated discrete and continuous covariates, and a latent class variable. It assumed covariate effects on survival times and covariate distributions vary across latent …

In drug-resistant focal epilepsy, planning surgical resection can involve presurgical intracranial EEG (iEEG) recordings to detect seizures and other iEEG patterns to improve postsurgical seizure outcome. We hypothesized that resection of tissue generating interictal high-frequency oscillations (HFOs, 80-500 Hz) in the iEEG predicts surgical outcome. In eight international epilepsy centres, iEEG was recorded during the presurgical evaluation of patients. The patients were of all ages, had epilepsy of all types, and underwent surgical resection of a single focus aiming at seizure freedom. In a prospective analysis, we applied a fully automated definition of HFO that was independent of the dataset. …

Children represent a highly complex and variable population for treatment, including interindividual differences in drug dose-exposure. Midazolam has been used as a sedative for hospitalized children on- and off-label; however, factors affecting interindividual variability (IIV) in observed clearance for this population are not fully understood and can result in extreme under- or overexposure. Obesity has been described as a significant influence on midazolam in adolescents, which could potentially alter drug exposure. The goal of this study was to use two modeling strategies to evaluate dose-exposure of midazolam in children with and without obesity. Population pharmacokinetic modeling assessed whether measures of …

Genetic, Transcriptomic, And Epigenomic Insights Into Sjögren's Disease: An Integrative Network Investigation And Immune Diseases Comparison

Faculty, Staff and Student Publications

Sjögren's disease (SjD) is a systemic autoimmune disorder primarily causing dry eyes and mouth. It frequently overlaps with other autoimmune diseases (AIDs), including rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE). However, the genetic basis of SjD remains underexplored, limiting our understanding of its connections to other immune-mediated conditions. In this study, we aimed to identify gene networks associated with SjD through the integration of genetic, transcriptomic, and epigenomic data. We further compared the genetic factors of SjD with other immune-mediated diseases. We analyzed genome-wide association studies (GWAS) summary statistics, DNA methylation, and transcriptomic data using our in-house network-based methods, …

White Matter Connections Within The Central Sulcus Subserving The Somato-Cognitive Action Network, Georgios P Skandalakis, Evan M Gordon, Nico U F Dosenbach, Et Al.

2020-Current year OA Pubs

The somato-cognitive action network (SCAN) consists of three nodes interspersed within Penfield's motor effector regions. The configuration of the somato-cognitive action network nodes resembles the one of the 'plis de passage' of the central sulcus: small gyri bridging the precentral and postcentral gyri. Thus, we hypothesize that these may provide a structural substrate of the somato-cognitive action network. Using microdissections of 16 human hemispheres, we consistently identified a chain of three distinct plis de passage with increased underlying white matter in locations analogous to the somato-cognitive action network nodes. We mapped localizations of plis de passage into standard stereotactic space …

8-oxoguanine (8-oxoGua) is one of the most frequent forms of oxidative DNA base lesions, repaired by 8-oxoguanine DNA glycosylase 1 (OGG1) via base excision repair (BER) pathway to maintain genome fidelity. The human allelic variant hOGG1^S326C, prevalent in Caucasians and Asians, has been regarded as a susceptibility factor for various diseases, yet its pathogenic mechanism remains elusive. In this study, we demonstrate that Ogg1^S326C/S326C mice exhibit increased and sustained airway inflammation compared with wild-type (WT) Ogg1^S326/S326 mice. Mechanistically, in response to inflammatory stimulation, OGG1S326C undergoes reactive oxygen species-induced dimerization, which impairs its base excision function, but …

Radiolabeled targeting agents have emerged as valuable tools for the treatment of disseminated cancer. Monoclonal antibodies (mAbs) are widely employed as carriers for diagnostic and therapeutic radionuclides due to their exceptional specificity and affinity. However, their prolonged circulatory half-life can diminish diagnostic efficacy and increase radiation exposure to non-target tissues in therapeutic applications, resulting in dose-limiting toxicities. To overcome this limitation, pretargeting technologies emerge as promising strategies to enhance tumor-to-background ratio and reduce radiation exposure of healthy tissues. Our previous work introduced a pretargeting concept leveraging the specific interaction between two peptide nucleic acid (PNA) probes, HP1 and HP2, as …
