Oncogenes destabilize STING in epithelial cell-derived cancer cells, such as head and neck squamous cell carcinomas (HNSCCs), to promote immune escape. Despite the abundance of tumor-infiltrating myeloid cells, HNSCC presents notable resistance to STING stimulation. Here, we show how saturated fatty acids in the microenvironment dampen tumor response to STING stimulation. Using single-cell analysis, we found that obesity creates an IFN-I-deprived tumor microenvironment with a massive expansion of suppressive myeloid cell clusters and contraction of effector T cells. Saturated fatty acids, but not unsaturated fatty acids, potently inhibit the STING-IFN-I pathway in HNSCC cells. Myeloid cells from obese mice show …

The bone marrow contains various populations of skeletal stem cells (SSCs) in the stromal compartment, which are important regulators of bone formation. It is well-described that leptin receptor (LepR)+ perivascular stromal cells provide a major source of bone-forming osteoblasts in adult and aged bone marrow. However, the identity of SSCs in young bone marrow and how they coordinate active bone formation remains unclear. Here we show that bone marrow endosteal SSCs are defined by fibroblast growth factor receptor 3 (Fgfr3) and osteoblast-chondrocyte transitional (OCT) identities with some characteristics of bone osteoblasts and chondrocytes. These Fgfr3-creER-marked endosteal stromal cells contribute to …

Armo: Automated And Reliable Multi-Objective Model For Lymph Node Metastasis Prediction In Head And Neck Cancer, Zhiguo Zhou, Liyuan Chen, Michael Dohopolski, David Sher, Jing Wang

Faculty, Staff and Student Publications

Objective:

Accurate diagnosis of lymph node metastasis (LNM) is critical in treatment management for patients with head & neck cancer. Positron emission tomography (PET) and computed tomography (CT) are routinely used for identifying LNM status. However, for small or less fluorodeoxyglucose (FDG) avid nodes, there are always uncertainties in LNM diagnosis. We are aiming to develop a reliable prediction model is for identifying LNM.

Approach:

In this study, a new automated and reliable multi-objective learning model (ARMO) is proposed. In ARMO, a multi-objective model is introduced to obtain balanced sensitivity and specificity. Meanwhile, confidence is calibrated by introducing individual reliability, …

Review Of The Tumor Microenvironment In Basal And Squamous Cell Carcinoma, Elizabeth Chiang, Haleigh Stafford, Jane Buell, Uma Ramesh, Moran Amit, Priyadharsini Nagarajan, Michael Migden, Dan Yaniv

Faculty, Staff and Student Publications

It is widely known that tumor cells of basal and squamous cell carcinoma interact with the cellular and acellular components of the tumor microenvironment to promote tumor growth and progression. While this environment differs for basal and squamous cell carcinoma, the cellular players within both create an immunosuppressed environment by downregulating effector CD4+ and CD8+ T cells and promoting the release of pro-oncogenic Th2 cytokines. Understanding the crosstalk that occurs within the tumor microenvironment has led to the development of immunotherapeutic agents, including vismodegib and cemiplimab to treat BCC and SCC, respectively. However, further investigation of the TME will provide …

A Rare Case Of Autopsy Proven Achromobacter Xylosoxidans Endocarditis Involving Tricuspid Valve: A Case Report, Chaitra Janga, Mackenzie Kramer, Ifrah Naeem, Lucy Checchio, Md, Zahra Qamar

Abington Jefferson Health Papers

Infective endocarditis refers to infection of one or more valves of the heart, with Achromobacter xylosoxidans (A. xylosoxidans) being a rare cause. So far, 24 cases of A. xylosoxidans endocarditis were reported, with only one case describing tricuspid valvular involvement. Despite the rarity of A. xylosoxidans endocarditis, it is important for clinicians to be aware of atypical presentation and the high mortality associated with it. We present an autopsy-proven case of tricuspid valve endocarditis in the setting of A. xylosoxidans bacteremia in a 43-year-old female.

Framing The Family: A Qualitative Exploration Of Factors That Shape Family-Level Experience Of Pediatric Genomic Sequencing, Hadley Stevens Smith, Emily S Bonkowski, Madison R Hickingbotham, Raymond Belanger Deloge, Stacey Pereira

Center for Medical Ethics and Health Policy Staff Publications

Families of children with rare and undiagnosed conditions face many psychosocial and logistical challenges that may affect their approach to decisions about their child’s care and their family’s well-being. As genomic sequencing (GS) is increasingly incorporated into pediatric diagnostic workups, assessing the family-level characteristics that shape the experience of pediatric GS is crucial to understanding how families approach decision-making about the test and how they incorporate the results into their family life. We conducted semi-structured interviews with parents and other primary caregivers of pediatric patients who were evaluated for a suspected genetic condition and who were recommended to have GS …

Analysis Of Adsorbed Polyphosphate Changes On Milled Titanium Dioxide, Using Low-Field Relaxation Nmr And Photoelectron Spectroscopy, Laura N Elliott, David Austin, Richard A Bourne, Ali Hassanpour, John Robb, John L Edwards, Stephen Sutcliffe, Timothy N Hunter

Faculty, Staff and Students Publications

In this study, changes in the adsorbed amount and surface structure of sodium hexametaphosphate (SHMP) were investigated for aluminum-doped TiO2 pigment undergoing milling. Relaxation NMR was utilized as a potential at-line technique to monitor the effect of milling on surface area and surface chemistry, while XPS was used primarily to consider the dispersant structure. Results showed that considerable amounts of weakly adsorbed SHMP could be removed with washing, and the level of dispersant removal increased with time, highlighting destructive effects of sustained high-energy milling. Nonetheless, there were no significant chemical changes to the dispersant, although increases to the bridging oxygen …

Apoptosis Induction In Jurkat T-Lymphocytes By Proton Pump Inhibitors (Ppis), Shreya Murali, Randall Reif

Departmental Honors & Graduate Capstone Projects

Apoptosis, commonly known as programmed cell death, constantly occurs in humans. As a cancer cell increases in acidity, apoptosis is induced. In healthy cells, proton pump proteins allow for H⁺ ions to permeate cellular membranes, regulating pH. However, proton pump inhibitors (PPIs), such as omeprazole, prevent proton movement. In previous studies, omeprazole induced cell death in Jurkat T lymphocytes; however, there was no confirmation of whether the cells died through apoptosis, or through necrosis, where the cell bursts. By using Annexin-V staining, the effects of omeprazole, dexlansoprazole, and esomeprazole on apoptosis induction can be measured. Cell death was observed …

The identification of biomarkers plays a crucial role in personalized medicine, both in the clinical and research settings. However, the contrast between predictive and prognostic biomarkers can be challenging due to the overlap between the two. A prognostic biomarker predicts the future outcome of cancer, regardless of treatment, and a predictive biomarker predicts the effectiveness of a therapeutic intervention. Misclassifying a prognostic biomarker as predictive (or vice versa) can have serious financial and personal consequences for patients. To address this issue, various statistical and machine learning approaches have been developed. The aim of this study is to present an in-depth …

TP53-mutant acute myeloid leukemia (AML) respond poorly to currently available treatments, including venetoclax-based drug combinations and pose a major therapeutic challenge. Analyses of RNA sequencing and reverse phase protein array datasets revealed significantly lower BAX RNA and protein levels in TP53-mutant compared to TP53-wild-type (WT) AML, a finding confirmed in isogenic CRISPR-generated TP53-knockout and -mutant AML. The response to either BCL-2 (venetoclax) or MCL-1 (AMG176) inhibition was BAX-dependent and much reduced in TP53-mutant compared to TP53-WT cells, while the combination of two BH3 mimetics effectively activated BAX, circumventing survival mechanisms in cells treated with either BH3 mimetic, and synergistically induced …

The mammalian spermatozoa produced in the testis require functional maturation in the epididymis for their full competence. Epididymal sperm maturation is regulated by lumicrine signalling pathways in which testis-derived secreted signals relocate to the epididymis lumen and promote functional differentiation. However, the detailed mechanisms of lumicrine regulation are unclear. Herein, we demonstrate that a small secreted protein, NELL2-interacting cofactor for lumicrine signalling (NICOL), plays a crucial role in lumicrine signalling in mice. NICOL is expressed in male reproductive organs, including the testis, and forms a complex with the testis-secreted protein NELL2, which is transported transluminally from the testis to the …

Occupational Therapists’ Role In Educating Caregivers On Pediatric Sensory Interventions Guided By Neurodiversity Principles, Deanna Bourgeois

Student Capstone Papers

Background: Neurodivergent children often experience differences in sensory processing and self-regulation. Traditional sensory-based interventions are frequently used by occupational therapy practitioners (OTP) and caregivers to address dysregulation. However, sensory-based interventions, while often strengths-based, are not always neurodiversity-affirming.

Problem: There are minimal educational resources available to both OTP and caregivers that promote neurodiversity-affirming sensory interventions to support neurodivergent children.

Methods: The purpose of this project was to create self-paced educational modules to teach neurodiversity-affirming sensory interventions that promote children's self-regulation. To achieve this goal, the student investigator developed virtual educational modules and piloted them with OTP, occupational therapy …

An Occupational Therapy Approach To Play For Pediatric Cancer Patients, Michelle Erika Dytan, Karen Park

Spring 2023 Virtual OTD Capstone Symposium

Play as an occupation has been long identified as a primary aspect of a child’s life (Moore & Lynch, 2017). Play provides children with ways to explore the world while learning skills to improve critical thinking, creativity, and positive self-esteem, and simply to have fun (Guirguis, 2018; Yanof, 2019). Children with cancer face barriers that limit their ability to engage in play, with negative consequences to their social, cognitive, and emotional development (Nijhof et al., 2018). There is an evident gap in a lack of play opportunities in community-based settings, which may limit a child’s personal development, social skills, and …

Case Series: Continued Remission Of Ptsd Symptoms After Discontinuation Of Prazosin, Christie Richardson, Jonathan Yuh, Jing Su, Martin Forsberg

Rowan-Virtua School of Osteopathic Medicine Departmental Research

Post-traumatic stress disorder is a debilitating chronic illness that affects 6 out of 100 adults after a severe trauma. The alpha-adrenergic antagonist prazosin, which is prescribed off-label for flashbacks and nightmares due to trauma, is often continued indefinitely due to reports of symptoms returning upon discontinuation. There is no standard guidance for a trial of discontinuation of prazosin due to intolerance or side effects. In this case series, three patients are started on prazosin leading to remission of trauma-related symptoms, and symptoms continue to remit after treatment for an average of about 2 years followed by discontinuation of the medication. …

Background: The proper use of PPE should be common practice among nurses who administer chemotherapy. However, despite training and education, many studies have demonstrated that infusion nurses’ PPE adherence is as low as 50%. Improper PPE use can increase exposure to chemotherapy and has potential adverse health effects including fertility issues and risks of cancer. Few …

Advance Care Planning: An Evidence-Based Practice Project, Gabrielle Alanna Harvey

Evidence-Based Practice Project Reports

Advance care planning (ACP) is a topic that can be difficult for patients and providers to discuss due to lack of time, knowledge, communication skills, and discomfort surrounding the subject (Barkley et al., 2019; Hafid et al., 2021; Halpert et al., 2022; Marin, 2022). Delayed or absent ACP discussions may lead to nonbeneficial care, increased healthcare costs, end of life suffering and increased post-death family distress (Halpert et al., 2022; O’Hanlon et al., 2018). The purpose of this evidence-based practice (EBP) project was to increase the discussions and documentation regarding ACP in a family practice setting. The PICOT question guiding …

Preoperative Frailty And Adverse Outcomes Following Coronary Artery Bypass Grafting Surgery In Us Veterans, Salil V. Deo, Yakov Elgudin

Faculty Scholarship

Background: Contemporary guidelines emphasize the value of incorporating frailty into clinical decision-making regarding revascularization strategies for coronary artery disease. Yet, there are limited data describing the association between frailty and longer-term mortality among coronary artery bypass grafting (CABG) patients. Methods: We conducted a retrospective cohort study (2016–2020, 40 VA medical centers) of US veterans nationwide that underwent coronary artery bypass grafting (CABG). Frailty was quantified by the Veterans Administration Frailty Index (VA-FI), which applies the cumulative deficit method to render a proportion of 30 pertinent diagnosis codes. Patients were classified as non-frail (VA-FI ≤ 0.1), pre-frail (0.1 < VA-FI ≤ 0.2), or frail (VA-FI > 0.2). We used …

Comparative Study Of Adenosine Analogs As Inhibitors Of Protein Arginine Methyltransferases And A Clostridioides Difficile- Specific Dna Adenine Methyltransferase, Jujun Zhou, Youchao Deng, Iredia D Iyamu, John R Horton, Dan Yu, Taraneh Hajian, Masoud Vedadi, Dante Rotili, Antonello Mai, Robert M Blumenthal, Xing Zhang, Rong Huang, Xiaodong Cheng

Faculty, Staff and Student Publications

S-Adenosyl-l-methionine (SAM) analogs are adaptable tools for studying and therapeutically inhibiting SAM-dependent methyltransferases (MTases). Some MTases play significant roles in host–pathogen interactions, one of which is Clostridioides difficile-specific DNA adenine MTase (CamA). CamA is needed for efficient sporulation and alters persistence in the colon. To discover potent and selective CamA inhibitors, we explored modifications of the solvent-exposed edge of the SAM adenosine moiety. Starting from the two parental compounds (6e and 7), we designed an adenosine analog (11a) carrying a 3-phenylpropyl moiety at the adenine N6-amino group, and a 3-(cyclohexylmethyl guanidine)-ethyl moiety at the …
