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 …

Differences in immune profiles of children and adults with COVID-19 have been previously described. However, no systematic studies have been reported from infants hospitalized with severe disease. We applied a multidimensional approach to decipher the immune responses of SARS-CoV-2 infected infants (n = 26; 10 subacute, 11 moderate and 5 severe disease; median age = 1.6 months) and matched controls (n = 14; median age = 2 months). Single cell (scRNA-seq) profiling of PBMCs revealed substantial alterations in cell composition in SARS-CoV-2 infected infants; with most cell-types switching to an interferon-stimulated gene (ISG^hi) state including: (i) …

Tacrolimus Dosing In Liver Transplant Recipients Using Phenotypic Personalized Medicine: A Phase 2 Randomized Clinical Trial, Jeffrey Khong, Megan Lee, Curtis Warren, Un Kim, Sergio Duarte, Kenneth Andreoni, Sunaina Shrestha, Mark Johnson, Narendra Battula, Danielle Mckimmy, Thiago Beduschi, Ji-Hyun Lee, Derek Li, Chih-Ming Ho, Ali Zarrinpar

Tacrolimus is the most commonly used immunosuppression drug after solid organ transplantation; however, its dosing is challenging due to substantial inter-individual variability, often resulting in blood levels that deviate from the target therapeutic range. We explored whether a dynamically customized, phenotypic-outcome-guided drug dosing method could improve maintenance of drug trough levels within pre-determined target ranges, focusing on tacrolimus immediately after liver transplantation. This single-center, partially blinded, completed clinical trial involved 62 adults undergoing liver transplantation, block randomized into parallel groups: standard-of-care (SOC) clinician-determined or Phenotypic Personalized Medicine (PPM)-guided tacrolimus dosing. The primary outcome was percentage of post-transplant days with large …

Kenney, Samuel Wilson, Morgan Rosser, Sophie Lanzkron, Julie Kanter, Susan Padrino, Payal Desai, Deepa Manwani, Alice Cohen, Stephanie Guarino, Ward Hagar, Joshua Field, Jane Little

Department of Medicine Faculty Papers

Sickle cell disease (SCD) affects millions of individuals worldwide, and is characterized by both acute, episodic pain and chronic, persistent pain. Despite the significant burden of the disease, clinicians continue to face significant challenges in treating SCD pain due to variability in pain experiences. The objectives of this study were (1) to identify distinct pain subgroups based on demographic and biopsychosocial characteristics and (2) to evaluate the relationship between the subgroups and pain impact - a SCD-disease specific measure of pain interference. To achieve these objectives, we performed a hierarchical cluster analysis on a cross-sectional sample of adults with SCD …

Label-Free Multimodal Optical Biopsy Reveals Biomolecular And Morphological Features Of Diabetic Kidney Tissue In 2d And 3d, Anthony A Fung, Zhi Li, Craig Boote, Petar Markov, Joseph P Gaut, Sanjay Jain, Lingyan Shi

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, …

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 …

Intraspecific Sensory Diversity And The Decapod Claw: Patterns Of Sensillation Are Heterochelic And Sexually Dimorphic In Pagurus Bernhardus, Ari Drummond, Summer Nash, Tianna Holloway, Alexander Wilson, Lucy Turner, Mark Briffa, David T Bilton

School of Biological and Marine Sciences

Information detection affects physiological performance and behaviour and is vital to survival and fitness. Despite the recognised importance of sensory adaptations in information acquisition and manipulation, many forms of sensory variation—from within individuals to between species—remain underexplored. To better understand the role of information in evolution, it is important to examine sensory variation as part of a cohesive framework of sensory diversity. Using the decapod claw, a structure well-recognised for its morphological variation, we investigated sensory diversity at the intraspecific level by assessing heterochely and sexual dimorphism in the chelar morphologies of Pagurus bernhardus hermit crabs. We employed a novel …

Disruption Of Oocyte Sumoylation Impacts Critical Regulatory Processes During Folliculogenesis In Mice, Zian Liao, Tessa E Steenwinkel, Bruno Moscoso, Ernesto Salas, Bethany K Patton, Amanda Rodriguez, Anna Malovannaya, Stephanie A Pangas

Faculty, Staff and Students Publications

The conjugation of small ubiquitin-like modifiers (SUMO) to target proteins, known as SUMOylation, plays a crucial role in regulating protein homeostasis, activity, interaction with other proteins, and subcellular localization. Loss of SUMOylation in nongrowing oocytes by conditional deletion of the E2 SUMO conjugating enzyme, Ube2i, at the primordial follicle stage leads to female sterility due to complex changes in oocyte development, including altered folliculogenesis, defective meiotic progression, and premature loss of the ovarian reserve. In this study, proteomics was used to compare control and Ube2i conditional knockout ovaries during the first wave of folliculogenesis to identify key differences that may …

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 …

Structural Proteomics Defines A Sequential Priming Mechanism For The Progesterone Receptor, Matthew D Mann, Min Wang, Josephine C Ferreon, Phoebe S Tsoi, Michael P Suess, Antrix Jain, Anna Malovannaya, Roberto Vera Alvarez, Bruce D Pascal, Raj Kumar, Dean P Edwards, Patrick R Griffin

Faculty, Staff and Students Publications

The progesterone receptor (PR) is a steroid-responsive nuclear receptor with two isoforms: PR-A and PR-B. Disruption of PR-A:PR-B signaling is associated with breast cancer through interactions with oncogenic co-regulatory proteins (CoRs). However, molecular details of isoform-specific PR-CoR interactions remain poorly understood. Using structural mass spectrometry, we investigate the sequential binding mechanism of purified full-length PR and intact CoRs, steroid receptor coactivator 3 (SRC3) and p300, as complexes on target DNA. Our findings reveal selective CoR NR-box binding by PR and unique interaction surfaces between PR and CoRs during complex assembly, providing a structural basis for CoR sequential binding on PR. …

The Menstrual Cycle And Exercise Performance: A Literature Review, Reagan E. Burchill

Honors Thesis

This literature review will examine the current research investigating the relationship between the female menstrual cycle, exercise performance, and exercise instruction. The menstrual cycle is a physiological series of events that includes specific hormones at each stage. These hormones may play a role in how females recover from exercise. This is particularly significant when considering the hormonal fluctuations across the female menstrual cycle, which influence recovery, injury risk, and exercise performance. This could indicate that the suggestions doctors and exercise trainers present to females may not be as beneficial for their health because the research is not specifically tailored to …

Intracellular Inclusions Induced By Patient-Derived And Amplified Α-Synuclein Aggregates Are Morphologically Indistinguishable, Rabab Al-Lahham, Mark E Corkins, Mohd Ishtikhar, Prakruti Rabadia, Santiago Ramirez, Victor Banerjee, Mohammad Shahnawaz

Faculty, Staff and Student Publications

Lewy Body Disease (LBD) and Multiple System Atrophy (MSA) are synucleinopathies with distinct prognoses and neuropathologies, however, with overlapping clinical symptoms. Different disease characteristics are proposed to be determined by distinct conformations of alpha-synuclein (α-Syn) aggregates, which can self-propagate and spread between cells via a prion-like mechanism. The goal of this study is to investigate whether α-syn aggregates amplified from brain and CSF samples of LBD and MSA patients using the Seed Amplification Assay (SAA) maintain α-Syn seeding properties similar to those of α-syn aggregates derived from patients' brains. To address this, SAA-amplified and un-amplified α-Syn aggregates from LBD and …

Understanding mechanisms of resistance to active therapies is crucial for developing more effective treatments. Here, we investigate resistance to anti-EGFR and anti-VEGF plus chemotherapy treatment in colorectal cancer (CRC) patients from the IMblaze370 trial (NCT02788279). While anti-VEGF does not select for secondary mutations, anti-EGFR leads to simultaneous mutations in EGFR and MAPK, but not PI3K pathway genes. Notably, we observe frequent acquired mutations in the EGFR extracellular but not intracellular domain and that patients with higher baseline expression of EGFR-ligands are prone to acquire resistant mutations. This data reveals a ligand-activated EGFR/MAPK-signaling dependency in CRC. We also observe enrichment for …

BACKGROUND: Social network data are essential and informative for public health research and implementation as they provide details on individuals and their social context. For example, health information and behaviors, such as HIV-related prevention and care, may disseminate within a network or across society. By harmonizing egocentric and digital networks, researchers may construct a sociocentric-like "fuzzy" network based on a subgroup of the population.

OBJECTIVE: We aimed to generate a more complete sociocentric-like "fuzzy" network by harmonizing alternative sources of egocentric and digital network data to examine relationships between participants in the Neighborhoods and Networks (N2) cohort study. Further, we …

Chronic hyperglycemia is a major risk factor for glomerular or retinal microangiopathy and cardiovascular complications of type 1 diabetes (T1D). At the interface of genetics and environment, dynamic epigenetic changes associated with hyperglycemia may unravel some of the mechanisms contributing to these T1D complications. In this study, blood samples were collected from 112 young patients at T1D diagnosis and 3 years later in average. Whole genome-wide bisulfite sequencing was used to measure blood DNA methylation changes of about 28 million CpGs at single base resolution over this time. Chronic hyperglycemia was estimated every 3-4 months by HbA1c measurement. Linear regressions …

T cell activation requires a substantial increase in NAD+ production, often exceeding the capacity of oxidative phosphorylation (OXPHOS). To investigate how T cells adapt to this metabolic challenge, we generate T cell-specific ADP/ATP translocase-2 knockout (Ant2-/-) mice. Loss of Ant2, a crucial protein mediating ADP/ATP exchange between mitochondria and cytoplasm, induces OXPHOS restriction by limiting ATP synthase activity, thereby impeding NAD+ regeneration. Interestingly, Ant2-/- naïve T cells exhibit enhanced activation, proliferation and effector functions compared to wild-type controls. Metabolic profiling reveals that these T cells adopt an activated-like metabolic program with increased mitobiogenesis and anabolism. Lastly, pharmacological inhibition of ANT …

Cancer genomic studies have identified frequent mutations in subunits of the SWI/SNF chromatin remodeling complex, including SMARCA4 in nonsmall cell lung cancer with a frequency of up to 33% in advanced-stage disease, making it the most frequently mutated complex. We and others have identified SMARCA2 to be synthetic lethal to SMARCA4, indicating that SMARCA2 is a high-value therapeutic target. Here, we disclose the discovery and characterization of potent, selective, and orally bioavailable cereblon-based SMARCA2 PROTACs. Biochemically, we showed that YDR1 and YD54 are potent SMARCA2 degraders. Further, we showed the antitumor growth inhibitory activity of YDR1 and YD54 in SMARCA4 …

Here, we report the outcomes for GEA cohorts receiving zanidatamab monotherapy or with chemotherapy (paclitaxel or capecitabine). The primary endpoint was safety and tolerability. Secondary endpoints were objective response rate (ORR), disease control rate, progression-free survival, pharmacokinetics, and immunogenicity. Seventy patients were enrolled (n = 29 monotherapy; n = 41 combination therapy); most received prior HER2-targeted agents (monotherapy, …

Human Genetic Variation Determines 24-Hour Rhythmic Gene Expression And Disease Risk, Ying Chen, Panpan Liu, Aniko Sabo, Dongyin Guan

Faculty, Staff and Students Publications

24-hour biological rhythms are essential to maintain physiological homeostasis. Disruption of these rhythms increases the risks of multiple diseases. Biological rhythms are known to have a genetic basis formed by core clock genes, but how individual genetic variation shapes the oscillating transcriptome and contributes to human chronophysiology and disease risk is largely unknown. Here, we mapped interactions between temporal gene expression and genotype to identify quantitative trait loci (QTLs) contributing to rhythmic gene expression. These newly identified QTLs were termed as rhythmic QTLs (rhyQTLs), which determine previously unappreciated rhythmic genes in human subpopulations with specific genotypes. Functionally, rhyQTLs and their …

Soil-transmitted helminth (STH) infections rank among the most prevalent communicable diseases of humans, yet detection of these parasites is mostly restricted to identifying active infection through fecal examinations. Currently, there are no commercial diagnostic tools to identify a prior whipworm or hookworm exposure, and the few serological assays for roundworm infection have not been well validated for crossreactivity or infections in humans. Such diagnostic restrictions limit the range of scientific and clinical questions that surround STH exposures and their implicated relationship to chronic diseases, such as autoimmunity, allergy, and cancer. The goal of this investigation was to evaluate the diagnostic …

Given their rarity and diversity, a fundamental understanding of the genomic underpinnings for many sarcoma subtypes is still lacking. To better define the molecular landscape of this group of diseases, we perform matched whole exome sequencing and RNA sequencing on a cohort of 1340 sarcoma tumor specimens. We identify recurrent somatic mutations and observe an increased mutational burden in metastatic vs. primary samples (p <  0.001). We observe frequent copy number alterations including whole genome doubling, with this feature being more common in metastatic tumors (p = 0.026). Estimation of immune cell abundances followed by hierarchical clustering identifies five immune subtypes ranging from low to high and we observe inferior overall survival in immune deplete clusters compared to immune enriched (p <  0.01). Interestingly, GIST predominantly form a distinct "immune intermediate" cluster that is marked by a specific enrichment for NK cells (FDR <  0.01).
