Uca1 As A Key Regulator Of The Warburg Effect During Anoikis Resistance In Colorectal Cancer Metastasis, Ricardo Pequeno Bracho, Salique Hassan Shaham, Yamile Abuchard Anaya, Sophia Leslie, Kyle Doxtater, Subhash Chauhan, Bilal Hafeez, Tamer Oraby, Manish K. Tripathi

Research Symposium

Colorectal carcinoma (CRC) is the second leading cause of cancer-related mortality in the United States. While localized CRC has a 90% five-year survival rate, this drops sharply to 14% upon metastasis. Metastasis occurs in approximately 40–50% of CRC cases and requires cancer cells to acquire anoikis resistance—a critical adaptation allowing survival after detachment from the extracellular matrix, enabling migration and colonization of secondary sites. Understanding the molecular mechanisms driving anoikis resistance, particularly those linked to altered glucose metabolism, is essential for developing targeted therapies for metastatic CRC.

Cancer cells frequently exhibit the Warburg Effect, a metabolic adaptation favoring glycolysis over …

Artesunate Enhances The Efficacy Of Enzalutamide In Advanced Prostate Cancer, Xinyi Wang, Jinghui Liu, Fengyi Mao, Yifan Kong, Qiongsi Zhang, Chaohao Li, Daheng He, Chi Wang, Yanquan Zhang, Ruixin Wang, Sally R. Ellingson, Qiou Wei, Zhiguo Li, Xiaoqi Liu

Markey Cancer Center Faculty Publications

Prostate cancer (PCa) is one of the leading causes of death among men worldwide. Treatments targeting the androgen receptor pathway remain the standard therapy for PCa patients. Enzalutamide (ENZ), a second-generation androgen receptor inhibitor, was developed to treat castration-resistant prostate cancer. However, while patients initially respond to ENZ, drug resistance typically develops within a few months. Artesunate (ART), a semisynthetic derivative of the Artemisinin plant, is approved for antimalaria treatment. In this study, we conducted an FDA-approved drug screening and identified ART as a potential candidate for overcoming ENZ resistance in PCa. Mechanistically, ART induces the degradation of c-Myc, enhancing …

The Role Of Secondary And Tertiary Structure In The Cap-Independent Translation Of Fgf-9 And Hif-1-Alpha, Amanda Michelle Whittaker

Dissertations, Theses, and Capstone Projects

Under normoxic conditions, eukaryotes initiate translation of RNA through eIF4E recognition of the 5’ cap. However, under cellular stress, eukaryotic translation must be initiated through a 4E-independent, or “cap-independent” mechanism, involving eukaryotic initiation factor 4G (eIF4G) binding directly to the 5’ untranslated regions (5’ UTR) of the RNA. eIF4G binding then recruits the ribosome to the transcript. While this mechanism is useful for translation of apoptotic transcripts and transcripts involved in cell survival, cap-independent translation is also utilized by oncogenic RNA for tumorigenesis. Previous work by our lab and others has categorized this recruitment and initiation mechanism as either internal-ribosome-entry-site …

The intent of this presentation is to learn about the compound’s occurrence, general/predicted properties, and advantages. The review will be a fluid development comparing imidazole derivatives of natural origin with antinociceptive/lethal properties from the last 5 years. This review would include both purely extracted products but also those modified by synthesis.

Characterizing And Targeting The Non-Catalytic Functions Of Phosphatase Of Regenerating Liver 3 (Prl-3) In Oncogenesis And Cancer Progression, Jeffery T. Jolly

Theses and Dissertations--Molecular and Cellular Biochemistry

Phosphatase of Regenerating Liver 3 (PRL-3) is frequently upregulated in various cancers and is associated with poor patient prognosis. Although traditionally studied for its phosphatase activity, PRL-3 also interacts with the CNNM family of magnesium transporters through its catalytic site, and these two functions are mutually exclusive at any given time. Most previous studies relied on a commonly used PRL-3 mutation that disrupts both phosphatase activity and CNNM binding, making it challenging to determine which function drives its oncogenic effects. To address this gap in the field, I utilized a panel of PRL-3 mutants that selectively disrupt either phosphatase activity …

Developing Novel Therapeutic Strategies For Mcrc With A Brafv600e Mutation, Mariah Geisen

Theses and Dissertations--Toxicology and Cancer Biology

Colorectal cancer (CRC) is the second leading cause of cancer death worldwide. The overall incidence rates of CRC have decreased in those over 50, but there is an increasing incidence rate in those under 50. Risk factors for CRC include diet, family history, and a sedentary lifestyle. Early detection of CRC is key to patient survival and treatment response. Localized CRC has a survival rate of 90% and allows for surgical resection and chemotherapy. The 5-year survival for metastatic CRC (mCRC) is significantly reduced to around 14%. Despite early detection, 50% of patients will develop metastasis after surgical resection and …

Analysis Of Differential Gene Expression In Androgen-Independent Clones Derived From The Mycap Pca Cell Line, Jessie L. Tignor, Melanie Sinanian, Richard Inho Joh, David Gewirtz, Jason Reed

Undergraduate Research Posters

Androgen deprivation therapy (ADT) is a primary treatment strategy for prostate cancer (PCa), yet many tumors eventually develop androgen independence, leading to treatment resistance. To investigate the molecular changes underlying this transition, we analyzed differential gene expression in four androgen-independent (AI) clones derived from the Myc-CaP prostate cancer cell line using RNA sequencing. Gene expression profiles were compared to the parental Myc-CaP line, and differentially expressed genes (DEGs) were identified using DESeq2 and edgeR. The AI clones exhibited significant downregulation of senescence-associated genes, including Ezh2 and lamin B1, suggesting a loss of senescence-related chromatin repression. Additionally, upregulation of Wnt pathway …

P85Α Degradation Mediated By Ubiquitin E3 Ligase Fbxo21 Offers Therapeutic Potential In Leukemia, Kasidy K. Weber

Theses & Dissertations

Acute myeloid leukemia (AML) is a complex and heterogeneous disease characterized by the clonal expansion of myeloid blasts in the bone marrow. Despite significant therapeutic advances over the years, the prognosis for AML patients remains dismal, with high relapse rates and poor overall survival. The ubiquitin-proteasome system (UPS) plays a critical role in maintaining cellular homeostasis by regulating the degradation of proteins involved in essential processes such as cell cycle control, DNA repair, apoptosis, and various signaling pathways. Given this vital function, targeting ubiquitin E3 ligases within the UPS presents a promising strategy for developing more effective and targeted therapies …

Investigating Tumor Growth And Regulation In Supratentorial Ependymomas; The Impact Of Dlk1 And Egr1 Knockout, Om Sinojia

Honors Scholar Theses

Ependymomas (EPNs) are primary brain tumors that often arise from radial glial cells lining the ventricular system. Supratentorial ependymomas (ST-EPNs) are particularly aggressive, and understanding the molecular factors driving their growth is critical for developing targeted therapies. This study investigates the roles of DLK1 and EGR1, key regulators in cellular differentiation and tumorigenesis, in the development of ST-EPNs. We utilized genetically engineered mouse models to induce postnatal knockouts of DLK1 and EGR1 and evaluated tumor growth using histological and imaging techniques. Tumor area was quantified across multiple brain sections from both male and female mice. DLK1 knockout brains exhibited consistent …

Assessing The Temporal Role Of Mir-200 Loss In Murine Models Of Nsclc, Jared Fradette

Dissertations and Theses (Open Access)

Lung cancer is the leading cause of cancer related deaths in the United States, with non-small cell lung cancer (NSCLC) making up a majority of new diagnoses. Metastasis is the big killer in NSCLC and is driven by epithelial-mesenchymal transition (EMT) and immune evasion. The microRNA 200 family is a master regulator of EMT and is implicated in immune regulation. In this study we have developed a novel genetically engineered mouse model (GEMM) and derived primary cell lines from them to explore the role of microRNA-200 in early EMT and immune changes. Our model combines conditional activation of Kras^{G12D …}

Effects Of Cadherin Mediated Contact Normalization On Oncogenic Src Kinase Mediated Gene Expression And Protein Phosphorylation, Rachel E Nicoletto, Cayla J Holdcraft, Ariel C Yin, Edward P Retzbach, Stephanie A Sheehan, Amanda A Greenspan, Christopher M Laugier, Jason Trama, Caifeng Zhao, Haiyan Zheng, Gary S Goldberg

Rowan-Virtua School of Osteopathic Medicine Departmental Research

Nontransformed cells form heterotypic cadherin junctions with adjacent transformed cells to inhibit tumor cell growth and motility. Transformed cells must override this form of growth control, called "contact normalization", to invade and metastasize during cancer progression. Heterocellular cadherin junctions between transformed and nontransformed cells are needed for this process. However, specific mechanisms downstream of cadherin signaling have not been clearly elucidated. Here, we utilized a β-catenin reporter construct to determine if contact normalization affects Wnt signaling in transformed cells. β-catenin driven GFP expression in Src transformed mouse embryonic cells was decreased when cultured with cadherin competent nontransformed cells compared to …

Electrical and Computer Engineering: Faculty Scholarship

This research introduces a novel method for evaluating the structural features of biomolecules, utilizing our innovative Elliptical Dichroism (ED) spectrometer specifically designed for stereochemical analysis. By integrating ED spectrometry with autocorrelation (AC) analysis, we investigate the conformational characteristics of biological molecules such as amino acids, proteins, and extracellular vesicles (EVs) induced by elliptically polarized UV absorption. Our streamlined approach offers a cost-effective and portable solution with minimal sample consumption and supports multiple working modes to efficiently characterize biomolecular structures. The insight from this new approach demonstrates potential applications in using biomolecular characterization for cancer detection.

Emerin Deficiency Drives Mcf7 Cells To An Invasive Phenotype, Emily Hansen, Christal Rolling, Matthew Wang, James M Holaska

Rowan-Virtua School of Osteopathic Medicine Departmental Research

During metastasis, cancer cells traverse the vasculature by squeezing through very small gaps in the endothelium. Thus, nuclei in metastatic cancer cells must become more malleable to move through these gaps. Our lab showed invasive breast cancer cells have 50% less emerin protein resulting in smaller, misshapen nuclei, and higher metastasis rates than non-cancerous controls. Thus, emerin deficiency was predicted to cause increased nuclear compliance, cell migration, and metastasis. We tested this hypothesis by downregulating emerin in noninvasive MCF7 cells and found emerin knockdown causes smaller, dysmorphic nuclei, resulting in increased impeded cell migration. Emerin reduction in invasive breast cancer …

Conversely, WYpK(NBD) demonstrated significant toxicity at 10 μM. These insights pave the way for optimizing peptide-based cellular treatments for exosome secretion purposes.

Placental Co-Transcriptional Activator Vestigial-Like 1 (Vgll1) Drives Tumorigenesis Via Increasing Transcription Of Proliferation And Invasion Genes, Heather Sonnemann

Dissertations and Theses (Open Access)

Vestigial-like 1 (VGLL1) is a co-transcriptional activator that binds to TEA domain containing transcription factors (TEADs). Its expression is upregulated in a variety of aggressive cancer types, including pancreatic and basal-like breast cancer, and increased transcription of VGLL1 is strongly correlated with poor prognosis and decreased overall patient survival. In normal tissues, VGLL1 is most highly expressed within placental trophoblast cells, which share the common attributes of rapid cellular proliferation and invasion with tumor cells. The impact of VGLL1 in cancer has not been fully elucidated and no VGLL1-targeted therapy currently exists. The aim of this study was to evaluate …

Interleukin 24 Induces Apoptosis Through Glycogen Synthase Kinase-3 Beta Inactivation In Prostate Cancer Cells, Sual J. Lopez, Moira Sauane

Theses and Dissertations

Interleukin 24 (IL-24) is a tumor-suppressing protein currently in clinical trials. IL-24 induces cancer-specific apoptosis by activating endoplasmic reticulum (ER) stress and mitochondria dysfunction. We have previously demonstrated that IL-24 leads to apoptosis in cancer cells by protein kinase A (PKA) activation in human breast cancer cells. To further understand the mechanism by which IL-24 induces apoptosis, I analyzed the role of glycogen synthase kinase-3 (GSK3), a highly conserved and normally active serine/threonine kinase in cancer cells and downstream target of PKA. The work reported here provides direct evidence that GSK3 was inhibited following IL-24 treatment in human prostate cancer …

Using Rapid Protein Degradation To Determine The Effect Of Runx1 Loss-Of- Function On Dna Damage Accumulation And Repair., Jackriel Pina Morales

Theses and Dissertations

Germline mutations in RUNX1 are associated with familial platelet disorder with a predisposition to myeloid malignancy (RUNX1-FPDMM), in which patients present with low platelet counts,excessive bleeding and bruising, and an increased risk of Acute Myeloid Leukemia (AML)/Myelodysplastic Syndrome (MDS) development throughout their lifetime. To understand how these loss-of-function mutations in RUNX1 drive predispose to malignancy, it is important to develop a detailed understanding of the molecular basis of RUNX1 function. While RUNX1 is a transcription factor, preliminary data from our group and work from others suggests that RUNX1 also interacts with proteins that are critical for DNA damage …

Rowan-Virtua School of Osteopathic Medicine Departmental Research

Maackia amurensis lectins serve as research and botanical agents that bind to sialic residues on proteins. For example, M. amurensis seed lectin (MASL) targets the sialic acid modified podoplanin (PDPN) receptor to suppress arthritic chondrocyte inflammation, and inhibit tumor cell growth and motility. However, M. amurensis lectin nomenclature and composition are not clearly defined. Here, we sought to definitively characterize MASL and its effects on tumor cell behavior. We utilized SDS-PAGE and LC-MS/MS to find that M. amurensis lectins can be divided into two groups. MASL is a member of one group which is composed of subunits that form dimers, …

Homeobox A10: Regulator Of Pancreatic Cancer Progression And Survival, Sophia G. Kisling

Theses & Dissertations

Pancreatic ductal adenocarcinoma (PDAC) has one of the lowest incidence rates among all major cancers, yet it is disproportionally responsible for 8% of all cancer deaths. This high death rate is primarily attributed to the immunosuppressive tumor microenvironment and a lack of clinically relevant molecular targets. However, the underlying biology responsible for these poor outcomes remains obscure. To facilitate improved management of PDAC, an in-depth understanding of the molecular player(s) involved in PDAC aggressiveness is needed. Therefore, we analyzed the transcriptomic profiles of PDAC patients with long- and short-term survival and performed gene set enrichment analysis (GSEA), identifying a novel …

Mucins: Drivers Of Cancer Cell And Microenvironment Crosstalk In Pancreatic Cancer, Xiaoqi Li

Theses & Dissertations

Mucins facilitate the pancreatic cancer (PC) initiation, progression, and metastasis. Among mucins, MUC4 has been reported to inhibit lymphokine-activated cell killing and induce the apoptosis of cytotoxic T-cells. Counterintuitively, MUC4 expression is upregulated by multiple T-cell-secreted cytokines, such as IFN-γ, IL-17, and stroma-secreted factors like retinoic acid. Previously, we have identified that nuclear receptor coactivator 3 (NCOA3) regulates the MUC1 and MUC4 expression by increasing chromatin accessibility and maintaining protein stability. However, the comprehensive crosstalk mediated by MUC4 in cancer cells and T-cells and how its upstream regulator, NCOA3, modifies the cancer cell-intrinsic behavior is still elusive. Here, we show …

Novel Spirocyclic Dimer (Spid3) Displays Potent Preclinical Effects In Hematological Malignancies, Alexandria Eiken

Theses & Dissertations

Chronic lymphocytic leukemia (CLL) is a heterogeneous disease characterized by the accumulation of mature CD5⁺ B-cells in the peripheral blood, bone marrow, and secondary lymphoid tissues (e.g., spleen and lymph nodes).Despite the efficacy of front-line therapies, CLL is still an incurable disease, highlighting the need for development of novel therapeutics and further study of resistance mechanisms. Within the lymph node CLL tumor microenvironment (TME), there is an upregulation of gene signatures associated with B-cell receptor (BCR) and downstream nuclear factor kappa B (NF-κB) signaling compared to CLL cells found within the blood or bone marrow niches. Additionally, BCR signaling …

Targeting Lifr/C-Myc/Ddx21 Axis To Overcome Docetaxel Resistance In Prostate Cancer, Sushanta Halder

Theses & Dissertations

Resistance to chemotherapy poses a significant challenge in the treatment of advanced-stage prostate cancer (PCa), specifically with chemotherapy drugs like docetaxel (Doce), which is often employed after the failure of hormone therapy. However, 50-90% of PCa patients develop resistance to docetaxel within three years of post-chemo treatment, compounded by serious adverse side effects necessitating dose reductions. Various strategies are being investigated to address this issue, including identifying new therapeutic targets or mechanisms, developing novel combination therapies, and optimizing dosing regimens. In particular, our research is focused on uncovering the underlying mechanisms of resistance to docetaxel, such as the activation of …

Investigating The Modulation Of Metastasis By Dax-1 In Adrenal Carcinoma Cells, Aarya Mishra

Undergraduate Honors Theses

The nuclear hormone receptor (NHR), DAX-1 (dosage-sensitive sex reversal, adrenal hypoplasia critical region, on chromosome X, gene 1), is important in adrenal and gonadal development as well as steroidogenesis. It is encoded by the NR0B1 gene and functions mainly as a transcriptional repressor. Classified as an orphan receptor within the NHR superfamily, DAX-1 has been shown to inhibit other NHRs including estrogen receptor, androgen receptor and steroidogenic factor 1. DAX-1 is found to be underexpressed in breast and prostate cancers and, specifically in prostate cancer, is believed to be a transcriptional repressor of genes that are involved in epithelial-mesenchymal transition …

Epigenetic Modification As A Therapeutic Target In Brafv600e-Mutated Metastatic Colorectal Cancer, Hey Min Lee

Dissertations and Theses (Open Access)

Patients with BRAF^V600E-mutated metastatic colorectal cancer (mCRC) experience a worse prognosis and demonstrate only a 5% response rate to BRAF inhibitor treatment. In this study, adaptive resistance, and a potential combination of standard therapies in BRAF^V600E CRC were unveiled. Intriguingly, a robust association of BRAF^V600E mutation and DNA hypermethylation suggests this is a unique subgroup harboring aberrant epigenetic phenotype. Firstly, DNA methyltransferase (DNMT) inhibitor treatment induced profound DNA hypomethylation in vivo, but minimal change in gene expression due to adaptive elevation of the repressive histone methylation, H3K27me3, leading to compensatory suppression of key tumor suppressor genes, …

Maldi-Msi Identification Of Tissue-Level N-Glycomic And Proteomic Molecular Biomarkers Of Aggressive Prostate Cancer, Jordan Paige Hartig

MUSC Theses and Dissertations

Prostate Cancer (PCa) poses a significant clinical challenge, characterized by debates on screening efficacy and continuous issues with distinguishing aggressive from non-aggressive tumors. Despite treatment advancements, poor patient outcome at late stages and clinical overtreatment of indolent disease emphasizes the urgent need for markers of PCa aggression. Aberrant glycosylation and extracellular matrix (ECM) remodeling are two complex molecular processes necessary for PCa progression, highlighting a novel area for biomarker discovery. Leveraging formalin-fixed paraffin-embedded tissues, tissue microarrays (TMAs), and matrix-assisted laser desorption/ionization mass spectrometry imaging (MALDI-MSI), distinct N-glycan and ECM profiles are identified. Elevated bisecting, multi-antennary, and fucosylated N-glycans indicate early …

Undergraduate Research Symposium

Triple negative breast cancer (TNBC) is one of the most aggressive forms of breast cancer, and disproportionately affects African American women. TNBC cells lack the common hormone receptors that many pre-existing cancer treatments target. Fortunately, metal-based complexes with thiosemicarbazone ligands have gained significant attention for their potential as anti-cancer agents. Cobalt(III) complex ([Co(phen)2(MeATSC)](NO3)3•1.5H2O•C2H5OH]) and Copper(II) complex ([Cu(acetylethTSC)Cl]Cl•0.25C2H5OH) specifically have properties of high toxicity, which can contribute to decreased cancer cell activity. The effects of these complexes are currently being investigated on cancerous and non-cancerous breast cell lines. The cytotoxic effect of the cobalt(lll) complex and the copper(ll) complex was analyzed …

Remodeling Anaplastic Thyroid Cancer's Aggressive Profile And Metabolic Signature By Natural Alkaloid Berberine, Tara Elizabeth Jarboe

NYMC Student Theses and Dissertations

Anaplastic thyroid cancer is a rare, fatal cancer with a five-year survival of 4%. Universally diagnosed at stage IV, anaplastic thyroid cancer is characterized by its lack of differentiation, rapid proliferative rate, highly inflammatory tumor microenvironment, and metabolic dysregulation. Refractory to all established therapies, anaplastic thyroid cancer requires a novel therapeutic approach that targets all of these drivers of anaplastic thyroid cancer carcinogenesis. We propose natural alkaloid berberine as a therapeutic with multitarget efficacy to alter mitochondrial metabolism and reprogram anaplastic thyroid cancer’s aggressive phenotype. Our in vitro model uses monocyte cell line U937, anaplastic thyroid cancer cell lines T238 …
