Recent Advances In The Understanding And Management Of Primary Hyperparathyroidism., Melanie Goldfarb, Frederick R Singer

Articles, Abstracts, and Reports

Primary hyperparathyroidism is a hormonal disorder whose prevalence is approximately 1-2% in the United States of America. The disease has become more recognizable to clinicians in an earlier phase and, at present, patients can be diagnosed with "classic", "normocalcemic", "normohormonal", or "mild, asymptomatic" primary hyperparathyroidism. Surgery, with a focused parathyroidectomy when possible, or a four-gland exploration, is the only way to cure the disease. Cure is determined by use of intra-operative parathyroid hormone monitoring with long-term cure rates ranging from 90-95%. Newer adjuncts to surgery include CT or PET imaging and near-infrared immunofluorescence. This article highlights updates in parathyroid disease …

Classify Multicategory Outcome In Patients With Lung Adenocarcinoma Using Clinical, Transcriptomic And Clinico-Transcriptomic Data: Machine Learning Versus Multinomial Models, Fei Deng, Lanlan Shen, He Wang, Lanjing Zhang

Children’s Nutrition Research Center Staff Publications

Classification of multicategory survival-outcome is important for precision oncology. Machine learning (ML) algorithms have been used to accurately classify multi-category survival-outcome of some cancer-types, but not yet that of lung adenocarcinoma. Therefore, we compared the performances of 3 ML models (random forests, support vector machine [SVM], multilayer perceptron) and multinomial logistic regression (Mlogit) models for classifying 4-category survival-outcome of lung adenocarcinoma using the TCGA. Mlogit model overall performed similar to SVM and multilayer perceptron models (micro-average area under curve=0.82), while random forests model was inferior. Surprisingly, transcriptomic data alone and clinico-transcriptomic data appeared sufficient to accurately classify the 4-category survival-outcome …

Potential Use Of Dopamine And Dopamine Agonists As Angiogenesis Inhibitors In The Treatment Of Cancer, Benjamin Finley, Katherine Liu, Daniel Powell, Jamie Kellner, David H. Kinder

Pharmacy and Wellness Review

In recent years, there have been numerous developments in monoclonal antibodies used as anticancer drugs with a focus on reducing the ability of cancers to metastasize and produce new vasculature. These agents are called angiogenesis inhibitors and although these agents have been proven effective in treating certain types of cancers, production and administration of monoclonal antibodies comes at a steep cost with a severe side effect profile. Under normal physiologic conditions, angiogenesis is an important mechanism to create new blood vessels from preexisting vessels, usually occurring in adults. Tumor cells can hijack the angiogenesis pathway to produce new distant tumors …

The Role Of Ros In The Progression And Treatment Of Castration-Resistant Prostate Cancer, Dannah R. Miller

Theses & Dissertations

Prostate cancer is the second leading cause of cancer-related deaths in U.S. men, primarily due to the development of castration-resistant (CR) prostate cancer (PCa), of which there are no effective treatment options. Reactive oxygen species (ROS) plays a critical role in prostate carcinogenesis, including the progression of the CR PCa phenotype. ROS regulates both cell proliferation and apoptosis; a moderate increase in ROS can promote proliferation; however, a substantial rise in ROS levels will result in apoptosis. Oxidase p66Shc is elevated in clinical PCa cells and has been associated with a metastatic phenotype of CR PCa cells, promoting PCa cell …

A Rare Case Of A Non- Functioning Pancreatic Neuroendocrine Tumor, Yaser Khalid, Neethi Dasu, Richard Gordon

Rowan-Virtua Research Day

Pancreatic neuroendocrine tumors (PNET) are very rare and represent about 1–2% of all pancreatic tumors. Non-functional PNET (NF-PNET) is incidentally discovered in most cases. Most NF-PNETs are found at an advanced stage because patients are mostly asymptomatic. We present a case of 32-yr-old female who initially presented with increasing abdominal girth, decreased mobility, and lower extremity swelling up to the hip and was found to have an advanced NF-PNET with metastatic disease to the pelvis and liver. There have been few studies directed toward early detection and management; Computed tomography (CT) is the imaging modality of choice as well as …

Kinase Suppressor Of Ras 1 And Exo70 Promote Fatty Acid-Stimulated Neurotensin Secretion Through Erk1/2 Signaling, Stephanie Rock, Xian Li, Jun Song, Courtney M. Townsend, Heidi L. Weiss, Piotr G. Rychahou, Tianyan Gao, Jing Li, B. Mark Evers

Markey Cancer Center Faculty Publications

Neurotensin is a peptide hormone released from enteroendocrine cells in the small intestine in response to fat ingestion. Although the mechanisms regulating neurotensin secretion are still incompletely understood, our recent findings implicate a role for extracellular signal–regulated kinase 1 and 2 as positive regulators of free fatty acid-stimulated neurotensin secretion. Previous studies have shown that kinase suppressor of Ras 1 acts as a molecular scaffold of the Raf/MEK/extracellular signal–regulated kinase 1 and 2 kinase cascade and regulates intensity and duration of extracellular signal–regulated kinase 1 and 2 signaling. Here, we demonstrate that inhibition of kinase suppressor of Ras 1 attenuates …

Hdl In Endocrine Carcinomas: Biomarker, Drug Carrier, And Potential Therapeutic, Emily E. Morin, Xiang-An Li, Anna Schwendeman

Physiology Faculty Publications

High-density lipoprotein (HDL) have long been studied for their protective role against cardiovascular diseases, however recently relationship between HDL and cancer came into focus. Several epidemiological studies have shown an inverse correlation between HDL-cholesterol (HDL-C) and cancer risk, and some have even implied that HDL-C can be used as a predictive measure for survival prognosis in for specific sub-population of certain types of cancer. HDL itself is an endogenous nanoparticle capable of removing excess cholesterol from the periphery and returning it to the liver for excretion. One of the main receptors for HDL, scavenger receptor type B-I (SR-BI), is highly …

The incidence of thyroid cancer is significantly different between male and female patients. Thyroid cancer is also the only form of cancer where age can be considered a staging variable. Identifying biological prognostic factors such as age or sex is important as it helps select an optimal personalized therapy. The present analysis is an observational, prospective study that enrolled all patients with thyroid disease who were operated upon at a single center. The study aimed to determine the most frequent age at presentation, the predominance of one sex over the other, the incidence of malignant thyroid disease, and the relative …

Telotristat ethyl, a tryptophan hydroxylase inhibitor, was efficacious and well tolerated in the phase 3 TELESTAR study in patients with carcinoid syndrome (CS) experiencing ≥ 4 bowel movements per day (BMs/day) while on somatostatin analogs (SSAs). TELECAST, a phase 3 companion study, assessed the safety and efficacy of telotristat ethyl in patients with CS (diarrhea, flushing, abdominal pain, nausea or elevated urinary 5-hydroxyindoleacetic acid (u5-HIAA)) with < 4 BMs/day on SSAs (or ≥ 1 symptom or ≥ 4 BMs/day if not on SSAs) during a 12-week double-blind treatment period followed by a 36-week open-label extension (OLE). The primary safety and efficacy endpoints were incidence of treatment-emergent adverse events (TEAEs) and percent change from baseline in 24-h u5-HIAA at week 12. Patients (N = 76) were randomly assigned (1:1:1) to receive placebo or telotristat ethyl 250 mg or 500 mg 3 times per day (tid); 67 continued receiving telotristat ethyl 500 mg tid during the OLE. …

BACKGROUD: Multiple endocrine neoplasia type 2A (MEN2A) is a condition with inherited autosomal dominant mutations in RET (rearranged during transfection) gene that predisposes the carrier to extremely high risk of medullary thyroid cancer (MTC) and other MEN2A-associated tumors such as parathyroid cancer and/or pheochromocytoma. Little is reported about MEN2A syndrome in the Chinese population.

METHODS: All members of the 3 families along with specific probands of MEN2A were analyzed for their clinical, laboratory, and genetic characteristics. Exome sequencing was performed on the 3 probands, and specific mutation in RET was further screened on each of the family members.

RESULTS: Different …

The Role Of Progesterone Receptor Membrane Component 1 In Receptor Trafficking And Disease, Kaia K. Hampton

Theses and Dissertations--Pharmacology and Nutritional Sciences

The progesterone receptor membrane component 1 (PGRMC1) is a multifunctional protein with a heme-binding domain that promotes cellular signaling via receptor trafficking, and is essential for some elements of tumor growth and metastasis. PGRMC1 is upregulated in breast, colon, lung and thyroid tumors. We expanded the analysis of PGRMC1 in the clinical setting, and report the first analysis of PGRMC1 in human oral cavity and ovarian tumors and found PGRMC1 to correlate with lung and ovarian cancer patient survival. Furthermore, we discovered a specific role for PGRMC1 in cancer stem cell viability. PGRMC1 directly associates with the epidermal growth factor …

The Role Of 5-Alpha Reductase 3 In Steroid Metabolism, Zahi Mitri

Dissertations and Theses (Open Access)

Background

The growth and development of prostate cancer is largely driven by androgen mediated signaling. The 5-alpha reductase family of enzymes plays an essential role in the conversion of testosterone to the more potent androgen, 5-alpha dihydrotestosterone (DHT), which is capable of binding the androgen receptor to activate gene targets and downstream signaling. This study aimed to evaluate the role of 5-alpha reductase 3 (SRD5A3), a novel member of the 5-alpha reductase family, in steroid metabolism and prostate carcinogenesis.

Materials and Methods

HEK293 cells were transfected with the SRD5A3 human cDNA ORF Clone from OriGene. Steroid substrates (testosterone, progesterone, androstenedione, …

Vague Neuroglycopenic Complaints Camouflage Diagnosis Of Adolescent Insulinoma: A Case Report., Kelsee Halpin, Ryan Mcdonough, Patria Alba, Jared Halpin, Vivekanand Singh, Yun Yan

Manuscripts, Articles, Book Chapters and Other Papers

BACKGROUND: Insulinoma is a rare diagnosis in the general population with estimates of 1 in 250,000 people per year. Reports of these pancreatic islet cell tumors are even more unusual in children and adolescents. Chronic hypoglycemia due to an insulinoma often presents with neuroglycopenic symptoms that can easily be overlooked, especially in adolescents where nonspecific complaints are common. This may result in delayed diagnosis with prolonged periods of untreated hypoglycemia and associated complications. The rarity of pediatric insulinoma, vagueness of presenting symptoms, and challenge of tumor localization make insulinoma a true diagnostic quandary for clinicians.

No Association Of Obesity And Type 2 Diabetes Mellitus Related Genetic Variants With Colon Cancer, Cheryl L. Thompson, Sarah J. Plummer, Thomas C. Tucker, Graham Casey, Li Li

Markey Cancer Center Faculty Publications

Background: Obesity and type 2 diabetes mellitus (T2D) are known risk factors for colon cancer. Recent reports from a number of genome wide association studies (GWAS) have identified several single nucleotide polymorphisms (SNPs) associated with obesity and T2D. Here we tested the hypothesis that these SNPs may also be associated with risk of colon cancer.

Methods: We genotyped nine SNPs reported in GWAS of obesity and/or T2D, including SNPs in HHEX, KCNJ11, SLC30A8, FTO, CDKN2, CDKAL1, TCF2, and the rs9300039 SNP in an intergenic region, in 561 colon cancer cases and 721 population controls.

Results: None of these SNPs were …
