A Pedunculated Esophageal Chondromatous Hamartoma In A Child, Dan-Alexandru Iozsa, Maria Puscasu, Catalin Gabriel Cirstoveanu, Vlad Denis Constantin, Anca Silvia Dumitriu, Stana Paunica, Nicolae Sebastian Ionescu

Journal of Mind and Medical Sciences

Esophageal tumors are uncommon in pediatric population and most of them are benign. Esophageal hamartomas have been reported extremely rare in children. These can present as intramural tumors of the esophageal wall or as polyps. Dysphagia is the main symptom described in their case, but other specific symptoms are also reported. Such symptoms encountered in clinical practice are represented by obstructive apnea episodes and bradycardia, poor weight gain, epigastric or retrosternal pain, hematemesis or melena, dysphonia or tracheal sounds. Diagnosis can be delayed due to the insidious onset and non-specific symptoms, therefore patient’s compliance to follow-up and broad, careful evaluation …

Modern Approaches For Antiandrogen-Resistant Prostate Cancer Therapy, Felix Voinea, Laura Mazilu, Ioan Sergiu Micu, Adrian Paul Suceveanu, Madalina Iliescu, Andrada Dumitru, Vlad Denis Constantin, Ioana Paunica, Andra Iulia Suceveanu

Journal of Mind and Medical Sciences

Prostate cancer represents the leading malignant tumor in men over 50 years of age with 400,000 new cases being diagnosed yearly in Europe. Even if the incidence rate is higher than the mortality rate, still there is an increasing trend when speaking of its mortality. The increasing incidence of the metabolic syndrome, the unhealthy lifestyle, the high lipid and Calcium intake, the high spread of infections with Human Papilloma Virus, Human Herpes Virus, the excess of androgen consumption and the longer life expectancy, are few of the main causes of prostate cancer increasing incidence. The new systemic therapies such as …

A Mini-Review Regarding The Carcinogenesis And Morphology Of Serous Tumors Of The Ovary, Fallopian Tube And Peritoneum, Tiberiu-Augustin Georgescu, Roxana Bohiltea, Octavian Munteanu, Corina Grigoriu, Ioana Paunica, Maria Sajin

Journal of Mind and Medical Sciences

Similar to the already well-recognized adenoma-carcinoma sequence in colorectal cancer pathogenesis, it has been believed for many decades that the progression of ovarian epithelial tumors occurs from benign serous cystadenomas to borderline tumors, to well-differentiated carcinomas, and ultimately, to poorly differentiated carcinomas. However, it is currently accepted that low-grade serous carcinoma (LGSC) and high-grade serous carcinoma (HGSC) are fundamentally different tumor types and, consequently, different diseases. In fact, whereas the benign-borderline-malignant sequence seems to apply quite well to low-grade serous carcinoma, the sequence of genetic alterations in high-grade serous carcinoma is substantially different. In this mini-review, we included the current …

Biochemical And Echocardiographic Markers For The Early Detection Of Cardiotoxicity Under Monoclonal Antibodies Therapy, Ionela-Emilia Popovici, Angela Cozma, Olga Hilda Orasan, George Ciulei, Ana Maria Poenar, Cristina Buchman, Simina Tarmure, Sorina Secara, Adela Sitar-Taut, Teodora Alexescu, Andrada Lazar, Vasile Negrean, Lucia Maria Procopciuc

Journal of Mind and Medical Sciences

The progress made over the past years in the field of cancer therapy has led to a significant decrease in cancer mortality, but these therapies have many adverse effects, cardiovascular effects being among the most frequent ones. For increasing lifelong expectancy of surviving cancer patients, cardiac monitoring represents an important task. Current studies and practice recommend echocardiography using strain analysis for monitoring the cardio toxic effects of cancer therapy. The potential of combining imaging techniques with biomarkers for the early detection and diagnosis seems a promising path for future research.

Role Of Ampk And Akt In Triple Negative Breast Cancer Lung Colonization, Jeremy Johnson, Zeta Chow, Eun Young Lee, Heidi L. Weiss, B. Mark Evers, Piotr G. Rychahou

Pathology and Laboratory Medicine Faculty Publications

Triple negative breast cancer (TNBC) is an aggressive disease with a 5-y relative survival rate of 11% after distant metastasis. To survive the metastatic cascade, tumor cells remodel their signaling pathways by regulating energy production and upregulating survival pathways. AMP-activated protein kinase (AMPK) and Akt regulate energy homeostasis and survival, however, the individual or synergistic role of AMPK and Akt isoforms during lung colonization by TNBC cells is unknown. The purpose of this study was to establish whether targeting Akt, AMPKα or both Akt and AMPKα isoforms in circulating cancer cells can suppress TNBC lung colonization. Transient silencing of Akt1 …

MBC is considered a special type of breast cancer with a prognosis that is worse than invasive ductal carcinoma (IDC) of the breast. MBC is the most common breast cancer with a triple-negative profile. Therefore, in this study, we evaluated the clinicopathological parameters, recurrence and survival of MBC in our population.
Methods: We conducted a retrospective observational study in the Department of Histopathology at Prince Faisal Oncology Centre, Buraidah, Saudi Arabia, over a period of five years. All cases diagnosed as MBC were included in …

Structure, Function And Inhibition Of Critical Protein-Protein Interactions Involving Mixed Lineage Leukemia 1 And Its Fusion Oncoproteins, Xin Li, Yongcheng Song

Faculty, Staff and Students Publications

Mixed lineage leukemia 1 (MLL1, also known as MLL or KMT2A) is an important transcription factor and histone-H3 lysine-4 (H3K4) methyltransferase. It is a master regulator for transcription of important genes (e.g., Hox genes) for embryonic development and hematopoiesis. However, it is largely dispensable in matured cells. Dysregulation of MLL1 leads to overexpression of certain Hox genes and eventually leukemia initiation. Chromosome translocations involving MLL1 cause ~ 75% of acute leukemia in infants and 5-10% in children and adults with a poor prognosis. Targeted therapeutics against oncogenic fusion MLL1 (onco-MLL1) are therefore needed. Onco-MLL1 consists of the N-terminal DNA-interacting domains …

Predicting Tumor Response To Radiotherapy Based On Estimation Of Non-Treatment Parameters, Yutian Huang, Allison L. Lewis

Spora: A Journal of Biomathematics

Though clinicians can now collect detailed information about a variety of tumor characteristics as a tumor evolves, it remains difficult to predict the efficacy of a given treatment prior to administration. Additionally, the process of data collection may be invasive and expensive. Thus, the creation of a framework for predicting patient response to treatment using only information collected prior to the start of treatment could be invaluable. In this study, we employ ordinary differential equation models for tumor growth and utilize synthetic data from a cellular automaton model for calibration. We investigate which parameters have the most influence upon treatment …

Redefining Cancer Of Unknown Primary: Is Precision Medicine Really Shifting The Paradigm?, Timothée Olivier, Eugenio Fernandez, Intidhar Labidi-Galy, Pierre-Yves Dietrich, Veronica Rodriguez-Bravo, Giulia Baciarello, Karim Fizazi, Anna Patrikidou

Department of Cancer Biology Faculty Papers

The concept of Cancer of Unknown Primary (CUP) has evolved with the advent of medical oncology. CUP can be difficult to diagnose and represents 2 to 5% of new cancers, therefore not exceptionally rare. Within CUPs can be identified a subset of favourable prognosis tumours, however the vast majority of CUP patients belongs to a poor prognosis group. CUP features significant oncological challenges, such as unravelling biological and transversal issues, and most importantly, improving patient's outcomes. In that regard, CUP patients’ outcomes regrettably showed minimal improvement for decades and CUP remains a cancer group of very poor prognosis. The biology …

The Graduate School Posters

Cancers are aggressive, evasive, and ruthless killers, claiming millions of lives every year. Cancers are heterogeneous and there is often no single, clearly defined problem as they harness and manipulate a multitude of fundamental mechanisms at the very essence of life. To investigate these mechanisms and vet potential interventive therapies, humanized mice offer a unique model as a prelude to the use of nanosecond pulse stimulation (NPS), a pulse power technology applying nanosecond duration, high electric field pulses, to ablate human tumors. Immunodeficient mouse strains, NSG and NSG-SGM3, were engrafted with human immune cells and human tumors, which would allow …

Biophysical Characterization Of The Par-4 Tumor Suppressor: Evidence Of Structure Outside The Coiled Coil Domain And Interactions With Platinum Chemotherapeutics, Andrea Megan Clark

Chemistry & Biochemistry Theses & Dissertations

Prostate apoptosis response-4 (Par-4) is an apoptosis-inducing tumor suppressor protein. Full-length Par-4 has previously been shown to be a predominantly intrinsically disordered protein (IDP) under neutral conditions, with significant regular secondary structure evident only within the C-terminal coiled coil domain. However, IDPs can gain ordered structure through the process of induced folding, which often occurs under non-neutral conditions. Previous work has shown that the Par-4 leucine zipper, which is a subset of the C-terminal coiled coil domain, is disordered under neutral conditions, but forms a dimeric coiled coil at acidic pH. Increase in ionic strength was also shown to increase …

Ferrara, Mary-Keara Boss, Andrew Goodspeed, Matthew A. Burchill, Beth A. Jirón Tamburini, Edward D. Chan, Curtis R. Pickering, Eric T. Clambey, Sana D. Karam

Department of Radiation Oncology Faculty Papers

BACKGROUND: Numerous trials combining radiation therapy (RT) and immunotherapy in head and neck squamous cell carcinoma (HNSCC) are failing. Using preclinical immune cold models of HNSCC resistant to RT-immune checkpoint inhibitors, we investigate therapeutic approaches of overcoming such resistance by examining the differential microenvironmental response to RT.

METHODS: We subjected two HPV-negative orthotopic mouse models of HNSCC to combination RT, regulatory T cells (Treg) depletion, and/or CD137 agonism. Tumor growth was measured and intratumorous and lymph node immune populations were compared among treatment groups. Human gene sets, genetically engineered mouse models DEREG and BATF3-/-, flow and time-of-flight cytometry, RNA-Seq, …

The Heme-Regulated Inhibitor Pathway Modulates Susceptibility Of Poor Prognosis B-Lineage Acute Leukemia To Bh3-Mimetics, Kaitlyn Hill Smith

Theses and Dissertations (ETD)

Anti-apoptotic MCL1 is one of the most frequently amplified genes in human cancers and its elevated expression confers resistance to many therapeutics including the BH3-mimetic agents ABT-199 and ABT-263. The anti-malarial, dihydroartemisinin (DHA) translationally represses MCL-1 and synergizes with BH3-mimetics. To explore how DHA represses MCL-1, a genome-wide CRISPR screen identified that loss of genes in the heme synthesis pathway renders mouse BCR-ABL+ B-ALL cells resistant to DHA-induced death. Mechanistically, DHA disrupts the interaction between heme and the eIF2α kinase heme regulated inhibitor (HRI) triggering the integrated stress response. Genetic ablation of Eif2ak1, which encodes HRI, blocks MCL-1 repression in …

Faculty, Staff and Students Publications

BACKGROUND AND AIMS: High-resolution microendoscopy (HRME) is an optical biopsy technology that provides subcellular imaging of esophageal mucosa but requires expert interpretation of these histopathology-like images. We compared endoscopists with an automated software algorithm for detection of esophageal squamous cell neoplasia (ESCN) and evaluated the endoscopists' accuracy with and without input from the software algorithm.

METHODS: Thirteen endoscopists (6 experts, 7 novices) were trained and tested on 218 post-hoc HRME images from 130 consecutive patients undergoing ESCN screening/surveillance. The automated software algorithm interpreted all images as neoplastic (high-grade dysplasia, ESCN) or non-neoplastic. All endoscopists provided their interpretation (neoplastic or non-neoplastic) …

Approaching Neoadjuvant Therapy In The Management Of Early-Stage Breast Cancer., Tara Hyder, Saveri Bhattacharya, Kristine Gade, Azadeh Nasrazadani, Adam M Brufsky

Department of Medical Oncology Faculty Papers

Neoadjuvant therapy is integral to the treatment of early-stage breast cancer. Goals of treatment include surgical downstaging of the tumor, rendering inoperable tumors resectable, and de-escalating axillary surgery in those with clinically positive nodes. Additionally, response to treatment provides important prognostic information regarding risk of recurrence and guides future adjuvant treatment. Although chemotherapy serves as the backbone of neoadjuvant treatment, an increased understanding of the tumor's clinical course as well as its molecular and genetic make-up aids in individualizing treatment and developing novel agents. This review summarizes current clinical approaches and the future direction to the management of breast cancer …

Nmr Methods For Determining Lipid Turnover Via Stable Isotope Resolved Metabolomics, Penghui Lin, Li Dai, Daniel R. Crooks, Leonard M. Neckers, Richard M. Higashi, Teresa W.-M. Fan, Andrew N. Lane

Center for Environmental and Systems Biochemistry Faculty Publications

Lipids comprise diverse classes of compounds that are important for the structure and properties of membranes, as high-energy fuel sources and as signaling molecules. Therefore, the turnover rates of these varied classes of lipids are fundamental to cellular function. However, their enormous chemical diversity and dynamic range in cells makes detailed analysis very complex. Furthermore, although stable isotope tracers enable the determination of synthesis and degradation of complex lipids, the numbers of distinguishable molecules increase enormously, which exacerbates the problem. Although LC-MS-MS (Liquid Chromatography-Tandem Mass Spectrometry) is the standard for lipidomics, NMR can add value in global lipid analysis and …

Metabolism And Oncology: The Role Of Nutrition In Improving Cancer Outcomes, Michael A. Chapek

University Honors Theses

Despite significant advances in oncologic treatment, underlying cancer-associated metabolic derangements and nutritional needs remain largely neglected in cancer care. Cancer cachexia and protective metabolic changes exhibited by cancerous cells continue to pose formidable barriers to improving therapeutic outcomes and quality of life for patients. Cancer has traditionally been viewed as a proliferative disease caused by genetic mutations, but newer perspectives suggest that it is primarily a metabolic disease. The present paper discusses the etiology of cachexia and sarcopenia, and nutritional interventions that can be offered to patients suffering from these wasting disorders. The role of inflammation in cancer and the …

Veterinary Science Faculty Publications

Colon adenocarcinoma is a common cause of cancer-related deaths worldwide. Epithelial-mesenchymal transition is a major regulator of cancer metastasis, and increased understanding of this process is essential to improve patient outcomes. Long non-coding RNA (lncRNA) are important regulators of carcinogenesis. To identify lncRNAs associated with colon carcinogenesis, we performed an exploratory differential gene expression analysis comparing paired colon adenocarcinoma and normal colon epithelium using an RNA-sequencing data set. This analysis identified lncRNA ZFAS1 as significantly increased in colon cancer compared to normal colon epithelium. This finding was validated in an institutional cohort using laser capture microdissection. ZFAS1 was also found …

Myd88 L265p Elicits Mutation-Specific Ubiquitination To Drive Nf-Κb Activation And Lymphomagenesis, Xinfang Yu, Wei Li, Qipan Deng, Haidan Liu, Xu Wang, Hui Hu, Ya Cao, Zijun Y Xu-Monette, Ling Li, Mingzhi Zhang, Zhongxin Lu, Ken H Young, Yong Li

Faculty, Staff and Students Publications

Myeloid differentiation primary response protein 88 (MYD88) is a critical universal adapter that transduces signaling from Toll-like and interleukin receptors to downstream nuclear factor-κB (NF-κB). MYD88L265P (leucine changed to proline at position 265) is a gain-of-function mutation that occurs frequently in B-cell malignancies such as Waldenstrom macroglobulinemia. In this study, E3 ligase RING finger protein family 138 (RNF138) catalyzed K63-linked nonproteolytic polyubiquitination of MYD88L265P, resulting in enhanced recruitment of interleukin-1 receptor-associated kinases and elevated NF-κB activation. However, RNF138 had little effect on wild-type MYD88 (MYD88WT). With either RNF138 knockdown or mutation on MYD88 ubiquitination sites, MYD88L265P did not constitutively activate …

Ovarian Seromucinous Tumors: Clinicopathological Features Of 10 Cases With A Detailed Review Of The Literature, Romana Idress, Nasir Ud Din, Sabeehuddin Siddique, Saira Fatima, Jamshid Abdul Ghafar, Zubair Ahmad

Department of Pathology and Laboratory Medicine

Background: The 2014 WHO Classification of ovarian neoplasms introduced a new entity of seromucinous tumors associated with endometriosis. These tumors encompassed a spectrum from benign to malignant and included seromucinous cystadenoma/ cystadenofibroma, seromucinous borderline tumor/atypical proliferative seromucinous tumor and seromucinous carcinoma. However, the 2020 WHO Classification of Female Genital Tumours removed seromucinous carcinomas as a distinct entity and recategorized them as Endometrioid carcinomas with mucinous differentiation. Here we describe clinico-morphologic features of seromucinous tumors recategorizing cases originally diagnosed as seromucinous carcinoma in light of 2020 WHO classification and present detailed review of literature.
Methods: Slides of seromucinous tumors were reviewed. …

Expression And Function Of Transcription Factors Foxa1, Hoxb13 And Cdx2 In Prostate Cancer, Hamsat B. Anwar

University Honors Theses

Prostate cancer (PC) is the second leading cause of death in men, affecting around 190 thousand patients in 2020 alone (National Institute of Cancer, 2020). Much of the current research focuses on treatments for advanced PC, which is problematic due to the rapid evolution of tumors and development of treatment resistance. Cancer early detection presents a better approach to control and treat patients before they acquire an incurable disease. Earlier diagnosis of patients leads to better prognosis and a more comfortable treatment process (Etzioni et al., 2003). However, we currently lack molecular markers to stratify PC during its early stages. …

Hemorrhagic Giant Cell Tumor Of The Occipital Skull Base: A Case Report And Literature Review, Cihan Kadipasaoglu, Andrew Wahba, Meenakshi B Bhattacharjee, Branko Cuglievan, Stephen A Fletcher

Faculty, Staff and Student Publications

Giant cell tumor of bone is a benign but locally aggressive osteolytic neoplasm that represents 3% to 5% of all primary bone tumors, primarily found at the epiphyses of long bones. Less than 1% are of calvarial origin. Herein, we report a rare case of a nine-year-old girl with a hemorrhagic giant cell tumor of the left occipital skull base.
