Frailty And Neurocognition In Prostate Cancer, Lindsey Hanson

Theses & Dissertations

Prostate cancer (PCa) treatment often leads to distressing side effects ranging from muscle loss, physical inactivity, and fatigue to cancer associated cognitive decline (CACD). Evidence suggests that men treated with androgen deprivation therapy (ADT) may have a specifically high risk of CACD, partially due to increased frailty. However, the current literature on cognitive effects of ADT is equivocal. Therefore, the primary objectives of this study were to (1) compare cognitive function, physical activity (PA), and fitness in men receiving ADT, men scheduled to receive radiation, and men under active surveillance for PCa; (2) examine changes in cognitive performance and PA …

Memory T Cell Populations In Human Leukemia, Sara Mcelroy

Research Days

Background: Incorporating the immune system into cancer management is an area of robust research. Treatment modalities aimed at activating cytotoxic T cells against malignancies include immune checkpoint inhibitors, bispecific T-cell engagers, and chimeric antigen receptor (CAR) tumor-specific T cells. Most anti-cancer T cell research is narrowly focused, but knowledge about the nature of diverse sub-populations of T cells in cancer, particularly memory T cells, is vital prior to potential incorporation into therapies. T memory stem cells (Tscm) are of interest due to their longevity and powerful abilities of self-renewal and creating the full spectrum of memory CD8+ T cells, including …

Bilateral Teratomas In Pediatric Patient With Unilateral Ovarian Torsion, David Ho, Maya Borowczak, Archana Verma

Rowan-Virtua Research Day

Ovarian torsion is a surgical emergency found in both pediatric and adult populations. It involves the full or partial rotation of the vessels that supply the ovary, resulting in ischemia. In this report, we present the case of a pediatric patient arriving to the Pediatric Emergency Department (PED) for evaluation of right lower quadrant (RLQ) abdominal pain, who was found to have an ovarian torsion. In this particular case, the patient’s ovarian torsion was due to a teratoma, and imaging would later identify an additional smaller teratoma on the contralateral side. This case shows the importance of considering ovarian pathologies …

Case Report: Glioblastoma Tumor Presenting With Mild Changes In Memory, Samuel Thalathoti, Nicholas Palladino, James Espinosa, Alan Lucerna

Rowan-Virtua Research Day

We report a case of a 66-year-old female who presented to the ED with generalized headache and mild confusion, who was diagnosed with high-grade glial neoplasm. The differential diagnosis of headache is vast, but without red flags or symptoms is generally from a benign cause and easily treatable. However, even in the context of a normal neurologic physical exam, symptoms such as confusion, forgetfulness, and behavioral changes should merit imaging in the workup. Glioblastoma is the most common brain tumor, accounting for 47.7% of all cases, with an incidence of 3.21 per 100,000 population. Median age of diagnosis is 64 …

Effect Of Uracil Dna Glycosylase Activity On The Efficacy Of Thymidylate Synthase Inhibitor/Hdac Inhibitor Combination Therapies In Colon Cancer, Rashmi Kulkarni, Brian P Weiser

Rowan-Virtua Research Day

Human uracil DNA glycosylase (UNG2) is responsible for removing uracil bases from DNA and initiates base excision repair pathways. Accumulation of uracil or its fluorinated analogs in DNA is one of the killing mechanisms of thymidylate synthase (TS) inhibitors in cancer cells, and depletion of UNG2 often enhances the toxicity of these anticancer drugs. We tested the effect of UNG2 KO on the efficacy of multiple TS inhibitors (5-fluorouracil, fluorodeoxyuridine, and pemetrexed) and we determined that, except for 5-fluorouracil, all other TS inhibitors were significantly more potent in UNG2 KO cells compared to wild-type HT29 cells. Interestingly, UNG2 protein levels …

Factors And Outcomes Contributing To Pelvic Lymph Node Dissection In Non-Muscle Invasive Bladder Cancer, Young Son, Brian Thomas, Lance Earnshaw, Mark Quiring, Erica Martel, Benjamin Fink, Raeann Dalton, Thomas Mueller, Philip Dorsey

Rowan-Virtua Research Day

Bladder cancer represents the 6th most common for men and is classified into muscle-invasive bladder cancer (MIBC) and non-muscle-invasive bladder cancer (NMIBC). NMIBC (T1, Ta, Tis), accounting for approximately 75% of new bladder cancer diagnoses, is limited to the mucosa, submucosa, and lamina propria. Studies have approximated the rate of recurrence in NMIBC between 50 - 70%, which sometimes progresses to muscle invasive disease. Management of NMIBC ranges from surveillance, intravesical chemotherapy to radical cystectomy (RC) and is dependent upon the TNM staging and grading of the tumor. Clinically, staging is determined via imaging, physical exam, and histology on transurethral …

Extragonadal Perirectal Mature Cystic Teratoma In The Adult Male, Pranamaya Mahankali, Liam Trimble, Diana Panciera, Hui Li, Thaer Obaid

Rowan-Virtua Research Day

A teratoma is a mass that originates from the germ cells of the three primitive embryonic layers and commonly arises from the ovaries or testicles, thereby characterized as gonadal in origin. These masses comprise different types of tissues such as fat, hair, muscle, and bone. Extragonadal teratomas are uncommon and arise from anatomical locations other than the gonads, such as the pineal gland, anterior mediastinum, retroperitoneum, and sacrococcygeal regions. The most common is the presacral region, as it contains tissue derived from all germ layers. Tumors in this specific location are far more common in neonates, infants, and children rather …

Interaction Of Fluorescent Probes With Sirtuin Proteins, James Fusco, Brian P Weiser

Rowan-Virtua Research Day

Sirtuins are a class of proteins belonging to the Sir2 (Silencing information regulator 2) family of NAD+ dependent protein lysine deacylases. Different Isoforms (SIRT1-SIRT7) differ in their specific deacylase activity and cellular location. They have roles in DNA repair, glucose metabolism, and cellular proliferation which make them highly desirable targets for carcinoma therapeutics. We previously used 1-aminoanthracene’s (AMA) fluorescent properties when bound with SIRT2 (Kd of 37 μM) to develop a high-throughput screen to identify novel ligands that inhibit SIRT2’s enzymatic activities. We hope to reveal other potential probes for future high-throughput screening with all the sirtuin isotopes. 1-AMA’s fluorescence …

Neoadjuvant Chemotherapy As A Risk Factor For Urinary Anastomotic Leak In Patients Undergoing Radical Cystectomy, Young Son, Katelyn Klimowich, Joseph Flemming, Lance Earnshaw, Benjamin Fink, Brian Thomas, Thomas Mueller

Rowan-Virtua Research Day

Muscle-invasive bladder cancer (MIBC) represents approximately 25% of all bladder cancer and carries a significant risk of mortality. Neoadjuvant chemotherapy (NAC) and radical cystectomy (RC) is the standard of care for MIBC. One complication associated with RC is ureteral anastomotic leak with a predicted rate of 3%. The objective of this National Surgical Quality Improvement Project (NSQIP) database analysis is to determine if correlations exist between radiation (RAD) and/or NAC before RC and anastomotic leak in the treatment of MIBC.

Management Of Late-Stage Ewingoid Dedifferentiated Liposarcoma Of The Spermatic Cord With Emergent Complications: A Case Report, Raeann Dalton, Abdullah Junayed, Brian Thomas, Young Son, Megan Donlick, Kathryn Goettle, Lance Earnshaw, Thomas Mueller

Rowan-Virtua Research Day

Liposarcoma (LS), a malignant tumor of adipose origin, is the most common soft tissue sarcoma (STS), and can develop within any soft tissue. It rarely occurs in the paratesticular region, and accounts for 3-7% of spermatic cord tumors. Dedifferentiated liposarcoma (DDLS) and well-differentiated liposarcoma (WDLS) account for two of the five subtypes of LS, with dedifferentiation occurring in 20% of cases. There have been 66 cases of DDLS of the spermatic cord reported to date, but none present with a 22/22q trisomy without the fusion or rearrangement that commonly produces these aggressive tumors.

Accurate diagnosis of LS of the spermatic …

Substrate-Specific Effect On Sirtuin Conformation And Oligomerization, Jie Yang, Shannon L. Dwyer, Nathan I. Nicely, Brian P. Weiser

Rowan-Virtua Research Day

Human sirtuins are a family of nicotinamide adenine dinucleotide (NAD +)-dependent enzymes that are responsible for removing acyl modifications from lysine residues. Sirtuins are involved in the formation and proliferation of cancers and are thought to regulate the progression of neurodegenerative diseases. Although sirtuins can be pharmacologically targeted by small molecules, it is not easy to modulate the substrate selectivity of sirtuins despite the chemical diversity of their substrates. Here, we report substrate-specific effects on sirtuin conformation and oligomerization that regulate enzyme deacylase activity. We used fluorescent acyl peptide probes to study substrate interactions with two sirtuin isoforms: SIRT2 and …

The Impact Of Racial Disparities And Outcomes On Urinary Anastomotic Leak In Radical Prostatectomy, Young Son, Benjamin A. Fink, Lance Earnshaw, Brian Thomas, Fred Okoye, Ryan Moriarty, Kathryn Goettle, Thomas Mueller

Rowan-Virtua Research Day

Prostate cancer is the leading malignancy and third most common cause of cancer death among men. In the United States, racial disparities exist in prostate cancer incidence and mortality rates. According to the National Cancer Institute, African American (AA) men have a significantly increased incidence of prostate cancer compared to Caucasians or Asians. Urinary leak at the urethrovesical anastomosis has been cited as a complication of radical prostatectomy (RP), with incidence rates as high as 23%. Urinary anastomotic leak is associated with increased rates of ileus, prolonged hospitalization rates, and longer time to achieve continence. The etiology of risk factors …

Plant Based Polyphenols Decrease Cell Migration And Inhibit Proliferation Of Human Pancreatic Cancer Cells, Mary Gathoni

Electronic Theses & Dissertations

Pancreatic cancer is one of the most highly malignant tumors of the digestive tract. Both the incidence and death rate of pancreatic cancer have increased since 2000. The disease has a poor prognosis with a relative 5-year survival rate of 10%. Pancreatic cancer-related mortality can be mainly attributed to lack of early diagnosis, tumor metastasis, lack of effective treatment strategies and drug resistance. There has been a mounting interest on the use of plant-based compounds such as polyphenols in cancer treatment therapies. This is mainly due to their low toxicity and fewer side effects compared to the conventional chemotherapeutic options …

The Role Of Obesity In Macrophage-Mediated Mechanisms Promoting Early-Onset Colon Cancer., Katharina Marietta Scheurlen

Electronic Theses and Dissertations

Early-onset colon cancer (EOCC) is a leading cause of cancer death among people younger than 50 years of age in the United States and is associated with metabolic dysfunction and obesity. Anti-inflammatory tumor-associated macrophages (TAM) and low Peroxisome Proliferator Activated Receptor Gamma (PPARγ) gene expression in colon cancer (CC) tissue promote tumor progression and decreased patient survival. Obesity-related hormones, such as leptin and adiponectin, have the potential to affect gene expression in TAM to promote CC progression and thereby link obesity and EOCC. The aim of this project was to identify target genes in human CC and to investigate the …

The Tca Cycle As A Nexus Of Metabolic Vulnerabilities In Cancer, Sunada Khadka

Dissertations & Theses (Open Access)

Uncontrolled proliferation of cancer cells necessitates rewiring of metabolic pathways to meet biosynthetic and bioenergetic demands of proliferation and fortify redox homeostasis. An increasing body of literature suggests that mitochondrial metabolism (tricarboxylic acid cycle (TCA) and oxidative phosphorylation) is imperative for cancer cell growth and proliferation. The scope of the works presented in this dissertation is to explore the importance of mitochondrial metabolism, and primarily the TCA cycle—the anabolic factory of cancer cells and leverage it as a targetable vulnerability in cancer. Cancer cells consume anabolic nutrients that are used to generate biosynthetic precursors in the TCA cycle. Continuous efflux …

Targeting Neuronal Nitric Oxide Synthase (Nnos) For Melanoma Treatment, Shirley Tong

Pharmaceutical Sciences (PhD) Dissertations

Human cutaneous melanoma is the most aggressive form of skin cancer and the incidence rates have continued to increase over the years. Neuronal nitric oxide synthase (nNOS) produces nitric oxide (NO) has been found to be overexpressed in human melanoma and the expression of nNOS is induced by interferon-gamma (IFN-γ). In our studies, nNOS has been implicated in IFN-γ-stimulated melanoma progression and the inhibition of nNOS using novel inhibitors effectively inhibited IFN-γ-stimulated tumor growth in a xenograft mouse model. Programmed death-ligand 1 (PD-L1) is overexpressed in melanoma and plays an important role in suppressing the immune system ^12-14. Our …

Targeting Protein Degradation To Uncover Novel Oncoprotein Drivers Of Acute Leukemia, Fatemeh Keramatnia

Theses and Dissertations (ETD)

Acute Lymphoblastic Leukemia (ALL), the most common childhood cancer and the second most common acute leukemia in adults, arises from clonal expansion of undifferentiated lymphoid precursor cells in bone marrow. Despite the extensive knowledge on its cytogenetic and molecular biology, ALL treatment remains highly challenging especially after relapse. Conventional chemotherapy has shown significant improvement in overall survival rates of pediatric patients up to 90%, however, treatment failure due to ALL relapse occurs in 15-20% of the cases. On the other hand, adults and elderly patients with ALL are considered difficult to treat populations with the 5-year overall survival of 30–40%. …

Investigation Of Oncogenic Ras And Endoplasmic Reticulum-Mitochondria Calcium Flux And Their Relationship In The Context Of Tumorigenesis, Emma Anderson

Senior Honors Theses

Intracellular calcium as a signaling molecule is a pervasive feature of cellular pathways, especially those that manage internal homeostasis and transitions through the cell cycle, so much so that regulated, responsive calcium flux between the endoplasmic reticulum (ER) and the mitochondria has been suggested to play a major role in cancer development. Another factor commonly implicated in tumorigenesis is RAS, an oncogene that controls signaling for many pathways that are also regulated by calcium. While both calcium and oncogenic RAS signaling are implicated in cancer development, possible links between them have yet to be determined. The identification of these links …

Paratesticular Solitary Fibrous Tumour Mimicking Cellular Angiofibroma: An Unusual Morphology And Rare Site, Madiha Bilal Qureshi, Muhammad Usman, Qurratulain Chundriger, Nasir Uddin

Department of Pathology and Laboratory Medicine

Solitary fibrous tumour (SFT) is a ubiquitous benign mesenchymal tumour of fibroblastic origin, which occurs most often in middle-aged adults. It usually presents as lung mass originating from pleura, but extrapleural occurrence is also common. Tumour is characterised by hypo- and hyper-cellular areas of spindle-shaped cells, arranged in haphazard manner with dispersed staghorn-shaped vessels. Surgical excision is the curative treatment. SFTs of the primary testicular or paratesticular region are extremely rare, but they exhibit histologic findings similar to SFTs originating at other body sites. Here, we report the case of a paratesticular SFT in a 37-year male, who presented with …
