Bard1: A Friend Or Foe In Pancreatic Ductal Adenocarcinoma?, Lily Zekavat, Aditi Jain

Department of Surgery Faculty Papers

Pancreatic ductal adenocarcinoma (PDAC) is an aggressive solid malignancy with poor overall prognosis and limited response to standard treatments. Growing interest in the modulation of DNA repair mechanisms, including the homologous recombination (HR) repair pathway, has opened new avenues for therapeutic development. BARD1 (BRCA1-Associated RING Domain 1) plays a complex role in tumor biology, functioning either as a tumor suppressor or as an oncogenic driver, depending on isoform expression, cellular context, and regulatory environment. In this review, we examine the dual roles of BARD1, focusing on its regulation and paradoxical activities in PDAC. We summarize evidence that BARD1 and BARD1 …

Subtype-Specific Her3 Enrichment In Basal-Like Breast Cancer Is Regulated Via The Gata2/Gata3–Foxa1 Axis, Congcong Tan, Hui Lyu, Sanbao Ruan, Yakun Wu, Margaret E. Larsen, Shou Ching Tang, Bolin Liu

School of Medicine Faculty Publications

Basal-like breast cancer (BLBC) is a major subtype of triple-negative breast cancer (TNBC), characterized by aggressive behavior, limited treatment options, and poor prognosis. While HER3 overexpression is frequently observed in TNBC and associated with poor outcomes, its subtype-specific expression and therapeutic potential remain unclear. Here, we demonstrated that HER3 signaling is selectively hyperactivated in BLBC compared to claudin-low breast cancer (CLBC) using transcriptomic profiling. Histone deacetylase inhibitors (HDACi), Romidepsin and Panobinostat, exerted potent antitumor effects on BLBC by selectively downregulating HER3 expression. HER3 levels were positively correlated with FOXA1, a key transcriptional activator. Mechanistically, we identified GATA2 and GATA3 as …

Extracellular matrix (ECM) components are key regulators in breast cancer progression, as ECM remodeling is essential for breast cancer cells to invade into surrounding tissue. This process is characterized by the alignment of fibrillar collagens, breakdown of basement membrane components, and increased interstitial collagen stiffness. In patients with obesity, pre-existing ECM changes, including excessive collagen deposition and heightened matrix stiffness, mimic alterations detected in breast cancer. Given that obesity is a predictor of poor prognosis and resistance to treatment in breast cancer, it is crucial to understand how ECM conditioned by obesity affects disease outcomes. In this review, we highlight …

Cells interact as dynamically evolving ecosystems. While recent single-cell and spatial multi-omics technologies quantify individual cell characteristics, predicting their evolution requires mathematical modeling. We propose a conceptual framework-a cell behavior hypothesis grammar-that uses natural language statements (cell rules) to create mathematical models. This enables systematic integration of biological knowledge and multi-omics data to generate in silico models, enabling virtual "thought experiments" that test and expand our understanding of multicellular systems and generate new testable hypotheses. This paper motivates and describes the grammar, offers a reference implementation, and demonstrates its use in developing both de novo mechanistic models and those informed …

Silvestrol Inhibits Nasopharyngeal Carcinoma Cells And Synergizes With Cx‑5461: Insights From A Proteomics Study, Maelinda Daker, Munirah Ahmad, Alan Khoo, Lu Ping Tan, Siok-Fong Chin, Siaw San Hwang, Paul Neilsen

Department of Medical Oncology Faculty Papers

Nasopharyngeal carcinoma (NPC) is a cancer arising from the epithelial cells of the nasopharynx, which is rare in Western countries but extremely prevalent in Borneo and the Southern China region. Present-day hurdles in NPC treatment that lead to poor quality of life and poor survival include distant metastasis and resistance to chemoradiotherapy. Silvestrol and its 5'''-epimer, episilvestrol, are compounds isolated from the plant Aglaia stellatopilosa, which is endemic to Borneo. Silvestrol, a protein synthesis inhibitor, preferentially inhibits the translation of cancer-associated mRNAs. CX-5461 is an inhibitor of RNA polymerase I that catalyzes rRNA synthesis. The present study sought to …

The novel (nua) kinases 1 and 2 are two of 12 AMP-activated protein–related kinases whose signaling pathways are involved in cancer progression, as well as neurologic, fibrotic, and inflammatory diseases. Currently, there are 80 Food and Drug Administration-approved kinase inhibitors which target roughly 24 of the 500+ known human kinases, leaving most kinases underexplored, including NUAK1 and NUAK2. Thus, there is a critical need for selective inhibition of NUAK1 and NUAK2 signaling. Here, we review the protein structure, known upstream regulators and downstream targets, and expression profiles of NUAK1 and NUAK2 in cancerous compared to noncancerous tissue. We also delineate …

Background & aims: Metastatic cancers arise from a decades-long succession of increasingly virulent precursor lesions, each of which represents prospective targets for therapeutic intervention. This evolutionary process has been particularly vivid in esophageal adenocarcinoma (EAC), as this cancer and associated precursor lesions, including Barrett's esophagus (BE), low-grade dysplasia (LGD), and high-grade dysplasia (HGD), coexist in an accessible, 2-dimensional pattern in esophageal mucosa. Given the durability of these precursor lesions, it is likely that they, like EAC, rely on stem cells for their regenerative growth. To assess the role of stem cells in the evolution of EAC, we apply technology that …

Fractional Flow Reserve From Coronary Ct: Evidence, Applications, And Future Directions, Arta Kasaeian, Mohadese Ahmadzade, Taylor Hoffman, Mohammad Ghasemi-Rad, Anoop Padoor Ayyappan

BACKGROUND: Podoplanin (PDPN) has emerged as a functionally relevant biomarker and chemotherapeutic target expressed by OSCC cells. PDPN signaling can directly increase tumor cell invasion and metastasis, and also inhibit host lymphocyte activation and immune response. Accordingly, antibodies and Maackia amurensis seed lectin (MASL) can target the PDPN receptor to inhibit OSCC cell migration and viability. However, the effects of MASL on OSCC cells in oral cancer patients has not yet been reported.

METHODS: We conducted a Phase 1 human clinical trial to examine the effects of a single 100 mg oral dose of MASL on OSCC cell morphology, PDPN …

Novel Piperidone And Bispidine Derivatives: A New Approach In Cancer Therapy, Lereen Khaled Youssry

Theses and Dissertations

Cancer remains the second leading cause of death worldwide. As a result, scientists have been trying to find novel therapeutic approaches that target specific metabolic pathways selective to tumor cells. In this study, two novel piperidone and bispidine derivatives, organic molecules that target polyamine metabolism, were synthesized, and their potential cytotoxic, antioxidant and anti-inflammatory effects were investigated. Polyamines are naturally occurring metabolites that were reported to be in excess at cancer cells and were accounted for tumor proliferation, invasion and metastasis. Accordingly, the novel piperidone and bispidine derivatives were expected to disrupt tumor growth and progression via up-regulation of key …

Department of Otolaryngology - Head and Neck Surgery Faculty Papers

Immune checkpoint inhibition (ICI) has emerged as a critical treatment strategy for squamous cell carcinoma of the head and neck (HNSCC) that halts the immune escape of the tumor cells. Increasing evidence suggests that the onset, progression, and lack of/no response of HNSCC to ICI are emergent properties arising from the interactions within the tumor microenvironment (TME). Deciphering how the diversity of cellular and molecular interactions leads to distinct HNSCC TME subtypes subsequently governing the ICI response remains largely unexplored. We developed a cellular-molecular model of the HNSCC TME that incorporates multiple cell types, cellular states, and transitions, and molecularly …

Duhadaway, Erika Sutanto-Ward, Maurice T. Hampton, Serguei V. Kozlov, George C. Prendergast, Alexander J. Muller

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

BACKGROUND: Strategies for deploying indoleamine 2,3-dioxygenase 1 (IDO1)-targeted therapies for use against cancer have focused on IDO1's role in promoting peripheral immune tolerance that shields tumors from effector T cells. However, preclinical investigation of both primary and metastatic tumor development in the lungs has uncovered a previously unappreciated role for IDO1 in directing a counterregulatory response to interferon (IFN)-γ that realigns the local inflammatory environment to promote tumor neovascularization. Understanding how to therapeutically leverage the ability of IDO1 inhibitors to subvert inflammatory neovascularization within the tumor microenvironment has potential ramifications for future clinical development of these compounds.

Rowan-Virtua Research Day

Acute myeloid leukemia (AML) is the most common leukemia in adult patients, with a 5-year survival rate of less than 30 percent. Therefore, more effective therapeutic strategies are required to prolong the survival of AML patients. Importantly, anti-apoptotic proteins, especially B-cell lymphoma 2 (Bcl-2), overexpression in AML is associated with uncontrolled growth as well as chemoresistance. Unsurprisingly, Bruton’s tyrosine kinase (BTK) overexpresses in AML and associated with poor prognosis and chemoresistance. The FDA-approved BTK inhibitor, ibrutinib, has been successful in treating other hematologic malignancies, but a proportion of patients relapse mainly because of acquired mutations at Cys481Ser (C481S) in the …

Exploring Intracellular Signaling Responses To Ks18, A Potent Mcl-1 Inhibitor, In Multiple Myeloma, Emily Nelson, Omar S Al-Odat, Dhruti A. Brahmbhatt, Tulin Budak-Alpdogan, Subash Jonnalagadda, Manoj Kumar Pandey

Rowan-Virtua Research Day

Multiple myeloma (MM), a cancer of plasma B cells, is a hematological malignancy in which patients inevitably relapse and develop drug resistance. Mcl-1, a member of the anti-apoptotic subgroup of Bcl-2 family proteins, plays a critical role in the progression of multiple myeloma and contributes significantly to drug resistance. Elevated Mcl-1 expression is observed in approximately 52% of MM patients at diagnosis, increasing to 81% at relapse. Given its driving role in disease progression and therapy resistance, Mcl-1 inhibition has emerged as a promising therapeutic target, prompting ongoing research into the development and clinical evaluation of Mcl-1 inhibitors, particularly for …

Targeting Bard1 Suppresses A Myc-Dependent Transcriptional Program And Tumor Growth In Pancreatic Ductal Adenocarcinoma, Sohum Patel, Eleanor Jenkins, Rutuj P. Kusurkar, Sherry Lee, Wei Jiang, Avinoam Nevler, Matthew Mccoy, Michael J. Pishvaian, Rosalie C. Sears, Jonathan R. Brody, Charles J. Yeo, Aditi Jain

Department of Surgery Faculty Papers

Pancreatic ductal adenocarcinoma (PDAC) remains one of the deadliest cancers demanding better and more effective therapies. BARD1 or BRCA1-Associated -Ring Domain-1 plays a pivotal role in homologous recombination repair (HRR). However, its function and the underlying molecular mechanisms in PDAC are still not fully elucidated. Here, we demonstrate that BARD1 is overexpressed in PDAC and its genetic inhibition suppresses c-Myc and disrupts c-Myc dependent transcriptional program. Mechanistically, BARD1 stabilizes c-Myc through ubiquitin-proteasome system by regulating FBXW7. Importantly, targeting BARD1 using either siRNAs or CRISPR/Cas9 deletion blocks PDAC growth in vitro and in vivo, without any signs of toxicity to mice. …

Clinical Implications Of Mismatch Repair Deficiency In Pancreatic Ductal Adenocarcinoma, Zachary Kaplan, Elizabeth Prezioso, Aditi Jain, Harish Lavu, Charles Yeo, Wilbur Bowne, Avinoam Nevler

Kimmel Cancer Center Faculty Papers

BACKGROUND: Pancreatic cancer is a highly aggressive and lethal disease, characterized by a limited response to chemotherapy and overall poor prognosis. Pancreatic cancers with a distinct mismatch repair deficiency, although relatively rare, have been shown to be associated with markedly better outcomes in comparison. Furthermore, whereas pancreatic cancers are generally unresponsive to current immunotherapy, this specific group of tumors has been shown to have a notable susceptibility to immune checkpoint inhibitors.

AIMS: In this review, we aim to summarize the relevant literature regarding mismatch-repair associated pancreatic cancers, the impacted biological mechanisms, and the resulting vulnerabilities for potential opportunistic immunotherapeutic treatment …

An Investigation Into The Potential Of Cell Therapies For Acute Myeloid Leukemia (Aml) Treatment, Amanda Eckstrom

Dissertations and Theses (Open Access)

Despite recent advances in acute myeloid leukemia (AML) treatment, curative rates remain poor with high rates of relapse and many patients are unable to tolerate the intensive chemotherapy standard of care regimen. Cell therapies have shown great success against hematologic malignancies but face several challenges including treatment-related toxicities and human-leukocyte antigen (HLA) matching. Natural killer (NK) cells and gamma delta (γδ) T cells offer alternative effector cell options for cell therapies that do not require HLA-matching and have shown low toxicity in previous studies. In this project, we sought to evaluate FT538 induced pluripotent stem cell-derived NK (iPSC-NK) and donor-derived …

Germ cell tumors of the testis (GCTs) provide an ideal tumor model to investigate the cellular versus genetic origin of cancers. In this single institutional study, we evaluated 38 patients with bilateral GCT, including tumors that occurred simultaneously (synchronous) and those occurring at different times (metachronous). For nine of these patients, DNA was isolated from the right and left GCT to determine the genomic and epigenetic differences between tissues using whole-exome sequencing (WES) and reduced representation bisulfite sequencing (RRBS). We found that seminomas and non-seminomas are molecularly distinct based on DNA methylation and not due to synchronous or metachronous disease. …

Ovarian cancer is associated with high rates of patient mortality and morbidity. Laparoscopic assessment of tumor localization can be used for treatment planning in newly diagnosed high-grade serous ovarian carcinoma (HGSOC). While spread to multiple intra-abdominal areas is correlated with worse outcomes, whether other morphological tumor differences are also associated with patient outcomes is unknown. Given the large volume of visual information in laparoscopic videos, we investigated whether deep-learning models can capture implicit features and predict treatment outcomes. We developed a novel deep-learning framework using pre-treatment laparoscopic images to assess clinical outcomes following upfront standard treatment, defined as short progression-free …

Desmoplastic Small Round Cell Tumor: An Update Of Current Management Practices, Ahmed Gawash, Alexa Simonetti, Brandon J Goodwin, Alissa Brotman O'Neill

Rowan-Virtua School of Osteopathic Medicine Departmental Research

BACKGROUND: Desmoplastic small round cell tumor (DSRCT) poses a diagnostic challenge, initiating with imaging techniques like ultrasound, CT, MRI, and PET scans, with CT being the primary choice for abdominal tumor visualization. Despite advances, the absence of a standardized staging system complicates the diagnostic process.

METHODS: A comprehensive literature review and search strategy, encompassing databases like PubMed and Cochrane was performed.

RESULTS: Systemic chemotherapy, notably the P6 regimen, is the cornerstone of DSRCT treatment, while other options, including CDK4/6 inhibitors, antibody-drug conjugates, and anlotinib present varying efficacy. A novel chemotherapeutic agent, ONC-201, exhibits promise, inhibiting tumor growth in preclinical models. …

Investigating The Effects Of Palmitoylation In Ovcar3 Cells, Bethany Knopp, Emu Suzuki

Undergraduate Research Symposium 2025

Ovarian cancer is a disease characterized by the abnormal growth of cells in the ovaries often due to mutations in our DNA. Because ovarian cancer is typically diagnosed at advanced stages, the survival rate is less than 40% over a five-year period. One significant influence of this cancer is palmitoylation - a post- translational modification in which fatty acid chains are added to specific cysteine residues in proteins. This modification alters protein localization, stability, and function. When dysregulated, as seen in ovarian cancer, palmitoylation can promote irregular cell growth, mutations, and ultimately cancer. However, the role of palmitoylation in cancer …

Missense Mutation Of Msh6 Leucine 696 Has No Apparent Effect On The Dna Mismatch Repair Process, Razan H. Hammad, Rafia Rashid, Essence Tarrence, Christopher Bolden, Joanna E. Haye-Bertolozzi

XULAneXUS

Lynch Syndrome and Constitutional Mismatch Repair Deficiency are human diseases implicated in mutations of DNA mismatch repair (MMR) genes. This experiment tested a mutation of an MMR gene, MSH6, and evaluated how the mutation affected overall MMR effectiveness. Using the yeast Saccharomyces cerevisiae, we performed the CAN1 forward mutation assay to study msh6-L696F and its implications in the MMR process. We hypothesized that there would be a significant change in molecular function in the Msh6 protein in the presence of this mutation. Bioinformatic tools predicted that this amino acid change would have deleterious effects on MMR function. However, …

Department of Medical Oncology Faculty Papers

Metastatic uveal melanoma is an aggressive disease with poor outcome, which is refractory to immune checkpoint inhibitors. A T cell receptor (TCR)-based CD3 bispecific, tebentafusp, delivers clinical benefit in patients with metastatic uveal melanoma. Understanding the molecular basis for the anti-tumor activity of tebentafusp in an indication where checkpoint inhibitors are ineffective could aid in identification of other solid tumor indications where CD3 bispecifics may serve an unmet need. By analyzing tumor biopsies taken prior to treatment, early on-treatment, and at progression (NCT02570308), using RNA sequencing (RNA-seq) and immunohistochemistry (IHC), we show that expression of interferon-related genes in the tumor …
