Examining Ndufab1 Expression In Head And Neck Squamous Cell Carcinoma, Addison L. Stevens

Honors Theses

Head and neck squamous cell carcinoma (HNSCC) accounts for around 4% of all cancers in the USA. HNSCC includes cancers of the oral cavity, oropharynx, nasopharynx, hypopharynx, and larynx. Reprogramming of mitochondrial metabolism has been known to promote oncogenesis. NDUFAB1, a nuclear encoded subunit of respiratory complex I (RCI) in the inner mitochondrial membrane, is abundantly expressed at the mRNA level in HNSCC patients. Based on this finding, we hypothesize that NDUFAB1 protein expression is high in HNSCC and that NDUFAB1 expression predicts a poor prognosis in HNSCC patients. We determined NDUFAB1 expression in HNSCC using immunohistochemistry and pathology guided …

Our objective was to test whether p53 expression status is associated with survival for women diagnosed with the most common ovarian carcinoma histotypes (high-grade serous carcinoma [HGSC], endometrioid carcinoma [EC], and clear cell carcinoma [CCC]) using a large multi-institutional cohort from the Ovarian Tumor Tissue Analysis (OTTA) consortium. p53 expression was assessed on 6,678 cases represented on tissue microarrays from 25 participating OTTA study sites using a previously validated immunohistochemical (IHC) assay as a surrogate for the presence and functional effect of TP53 mutations. Three abnormal expression patterns (overexpression, complete absence, and cytoplasmic) and the normal (wild type) pattern were …

The Effects Of Radiation On Cancer Stem Cells In Glioblastoma And Ovarian Cancer, Aaron Keniston

Electronic Theses, Projects, and Dissertations

High grade serous ovarian cancer (HGSOC) and glioblastoma multiforme (GBM) are some of the most aggressive forms of cancer with poor patient survival. Despite successful cancer therapies, these malignancies have high recurrence rates which can be attributed to cancer stem cells (CSC) due to innate tumor initiating properties. In this study, we investigated the response of CSC populations to proton and photon radiation by quantification of core stem cell transcription factors Sox2 and Oct4. This was carried out utilizing a Sox2/Oct4 green fluorescent protein based reporter designated as SORE6-GFP measured by flow cytometry. We hypothesize that proton and photon irradiation …

Faculty, Staff and Students Publications

BACKGROUND: Accurate and efficient methods to identify venous thromboembolism (VTE) events in hospitalized people are needed to support large-scale studies. Validated computable phenotypes using a specific combination of discrete, searchable elements in electronic health records to identify VTE and distinguish between hospital-acquired (HA)-VTE and present-on-admission (POA)-VTE would greatly facilitate the study of VTE, obviating the need for chart review.

OBJECTIVES: To develop and validate computable phenotypes for POA- and HA-VTE in adults hospitalized for medical reasons.

METHODS: The population included admissions to medical services from 2010 to 2019 at an academic medical center. POA-VTE was defined as VTE diagnosed within …

Methods: W hole-slide images of five oral t umor categories (n = 319 cases) were analyzed. Image patches were created from manually annotated regions at 4096, 2048, and 1024 pixels and rescaled to 256 pixels. Image representations were …

Ido1 And Inflammatory Neovascularization: Bringing New Blood To Tumor-Promoting Inflammation, Alexander J. Muller, Arpita Mondal, Souvik Dey, George C Prendergast

Kimmel Cancer Center Faculty Papers

In parallel with the genetic and epigenetic changes that accumulate in tumor cells, chronic tumor-promoting inflammation establishes a local microenvironment that fosters the development of malignancy. While knowledge of the specific factors that distinguish tumor-promoting from non-tumor-promoting inflammation remains inchoate, nevertheless, as highlighted in this series on the 'Hallmarks of Cancer', it is clear that tumor-promoting inflammation is essential to neoplasia and metastatic progression making identification of specific factors critical. Studies of immunometabolism and inflamometabolism have revealed a role for the tryptophan catabolizing enzyme IDO1 as a core element in tumor-promoting inflammation. At one level, IDO1 expression promotes immune tolerance …

Upregulation Of Cell Surface Glycoproteins In Correlation With Kshv Lana In The Kaposi Sarcoma Tumor Microenvironment, Sara R. Privatt, Owen Ngalamika, Jianshui Zhang, Qinsheng Li, Charles Wood, John T. West

School of Medicine Faculty Publications

HIV-associated epidemic Kaposi sarcoma (EpKS) remains one of the most prevalent cancers in sub-Saharan Africa despite the widespread uptake of anti-retroviral therapy and HIV-1 suppression. In an effort to define potential therapeutic targets against KS tumors, we analyzed previously published KS bulk tumor transcriptomics to identify cell surface biomarkers. In addition to upregulated gene expression (>6-fold) in the EpKS tumor microenvironment, biomarkers were selected for correlation with KSHV latency-associated nuclear antigen (LANA) expression. The cell surface glycoprotein genes identified were KDR, FLT4, ADAM12, UNC5A, ZP2, and OX40, as well as the endothelial lineage determinants Prox-1 and CD34. Each protein …

UNLABELLED: In acute myeloid leukemia (AML), SWI/SNF chromatin remodeling complexes sustain leukemic identity by driving high levels of MYC. Previous studies have implicated the hematopoietic transcription factor PU.1 (SPI1) as an important target of SWI/SNF inhibition, but PU.1 is widely regarded to have pioneer-like activity. As a result, many questions have remained regarding the interplay between PU.1 and SWI/SNF in AML as well as normal hematopoiesis. Here we found that PU.1 binds to most of its targets in a SWI/SNF-independent manner and recruits SWI/SNF to promote accessibility for other AML core regulatory factors, including RUNX1, LMO2, and MEIS1. SWI/SNF inhibition …

The incidence of bladder cancer and patient survival vary greatly among different populations, but the influence of the associated molecular features and evolutionary processes on its clinical treatment and prognostication remains unknown. Here, we analyze the genomic architectures of 505 bladder cancer patients from Asian/Black/White populations. We identify a previously unknown association between AHNAK mutations and activity of the APOBEC-a mutational signature, the activity of which varied substantially across populations. All significantly mutated genes but only half of arm-level somatic copy number alterations (SCNAs) are enriched with clonal events, indicating large-scale SCNAs as rich sources of bladder cancer clonal diversities. …

The availability of high-fidelity animal models for oncology research has grown enormously in recent years, enabling preclinical studies relevant to prevention, diagnosis, and treatment of cancer to be undertaken. This has led to increased opportunities to conduct co-clinical trials, which are studies on patients that are carried out parallel to or sequentially with animal models of cancer that mirror the biology of the patients' tumors. Patient-derived xenografts (PDX) and genetically engineered mouse models (GEMM) are considered to be the models that best represent human disease and have high translational value. Notably, one element of co-clinical trials that still needs significant …

Banking On Virus-Specific T Cells To Fulfill The Need For Off-The-Shelf Cell Therapies, David H Quach, Premal Lulla, Cliona M Rooney

Faculty, Staff and Students Publications

Adoptively transferred virus-specific T cells (VSTs) have shown remarkable safety and efficacy for the treatment of virus-associated diseases and malignancies in hematopoietic stem cell transplant (HSCT) recipients, for whom VSTs are derived from the HSCT donor. Autologous VSTs have also shown promise for the treatment of virus-driven malignancies outside the HSCT setting. In both cases, VSTs are manufactured as patient-specific products, and the time required for procurement, manufacture, and release testing precludes their use in acutely ill patients. Further, Good Manufacturing Practices-compliant products are expensive, and failures are common in virus-naive HSCT donors and patient-derived VSTs that are rendered anergic …
