Epidemiology and Environmental Health Faculty Publications

Background: We examined the association between metabolic dysregulation and cancer mortality in a prospective cohort of Black and White adults.

Methods: A total of 25,038 Black and White adults were included in the analysis. Metabolic dysregulation was defined in two ways: 1) using the joint harmonized criteria for metabolic syndrome (MetS) and 2) based on factor analysis of 15 variables characterizing metabolic dysregulation. We estimated hazards ratios (HRs) and 95% confidence intervals (CIs) for the association of MetS and metabolic dysregulation with cancer mortality during follow-up using Cox proportional hazards models.

Results: About 46% of Black and 39% of White …

Anderson, Jonathan Gorky, Prasad Dhurjati, Deni S. Galileo

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

BACKGROUND: Glioblastoma multiforme (GBM) is a devastating brain cancer for which there is no known cure. Its malignancy is due to rapid cell division along with high motility and invasiveness of cells into the brain tissue. Simple 2-dimensional laboratory assays (e.g., a scratch assay) commonly are used to measure the effects of various experimental perturbations, such as treatment with chemical inhibitors. Several mathematical models have been developed to aid the understanding of the motile behavior and proliferation of GBM cells. However, many are mathematically complicated, look at multiple interdependent phenomena, and/or use modeling software not freely available to the research …

Despite continued widespread use, the genomic effects of cisplatin-based chemotherapy and implications for subsequent treatment are incompletely characterized. Here, we analyze whole exome sequencing of matched pre- and post-neoadjuvant cisplatin-based chemotherapy primary bladder tumor samples from 30 muscle-invasive bladder cancer patients. We observe no overall increase in tumor mutational burden post-chemotherapy, though a significant proportion of subclonal mutations are unique to the matched pre- or post-treatment tumor, suggesting chemotherapy-induced and/or spatial heterogeneity. We subsequently identify and validate a novel mutational signature in post-treatment tumors consistent with known characteristics of cisplatin damage and repair. We find that post-treatment tumor heterogeneity predicts …

The Role Of Mucin-Educated Platelet Activation In Tumor Invasiveness: An Unfolding Concern In The Realm Of Cancer Biology, Akbar Shoukat Ali, Arzoo Ajaz

Department of Obstetrics & Gynaecology

Metastasis is a complex and well-coordinated phenotypic transformation of cancer cells governed by aberrant genetic and molecular pathways. It has been approved as the most consistent cause of cancer death. With emerging insight into the genomics, transcriptomics and proteomics, progress has been made and reasonably large number of molecular pathways of metastasis has been forwarded, but our understanding of precise underlying molecular mechanisms remains largely scarce. It has been well-known for around a decade and more that platelets are intriguingly contributing to the cancer metastasis. However, it is only recently that cancer cells can activate platelets have started to become …

Diverse Amide Analogs Of Sulindac For Cancer Treatment And Prevention, Bini Mathew, Judith V. Hobrath, Michele C. Connelly, R. Kiplin Guy, Robert C. Reynolds

Pharmaceutical Sciences Faculty Publications

Sulindac is a non-steroidal anti-inflammatory drug (NSAID) that has shown significant anticancer activity. Sulindac sulfide amide (1) possessing greatly reduced COX-related inhibition relative to sulindac displayed in vivoantitumor activity that was comparable to sulindac in a human colon tumorxenograft model. Inspired by these observations, a panel of diverse sulindac amide derivatives have been synthesized and their activity probed against three cancer cell lines (prostate, colon and breast). A neutral analog, compound 79 was identified with comparable potency relative to lead 1 and activity against a panel of lymphoblastic leukemia cell lines. Several new series also show good …

Glycolytic Reprogramming Through Pck2 Regulates Tumor Initiation Of Prostate Cancer Cells, Jiangsha Zhao, Jieran Li, Teresa W.M. Fan, Steven X. Hou

Toxicology and Cancer Biology Faculty Publications

Tumor-initiating cells (TICs) play important roles in tumor progression and metastasis. Identifying the factors regulating TICs may open new avenues in cancer therapy. Here, we show that TIC-enriched prostate cancer cell clones use more glucose and secrete more lactate than TIC-low clones. We determined that elevated levels of phosphoenolpyruvate carboxykinase isoform 2 (PCK2) are critical for the metabolic switch and the maintenance of TICs in prostate cancer. Information from prostate cancer patient databases revealed that higher PCK2 levels correlated with more aggressive tumors and lower survival rates. PCK2 knockdown resulted in low TIC numbers, increased cytosolic acetyl-CoA and cellular protein …

Department of Occupational Therapy Faculty Papers

Massage offers cancer patients general quality of life benefits as well as alleviation of cancer-related symptoms/cancer-treatment-related symptoms including pain, anxiety, and fatigue. Little is known about whether massage is accessible to cancer patients who receive treatment in the outpatient setting and how massage is incorporated into the overall cancer treatment plan. Outpatient cancer centers (n = 78) in a single metropolitan area were included this mixed-methods project that included a systematic analysis of website information and a telephone survey. Massage was offered at only 40 centers (51.3% of total). A range of massage modalities were represented, with energy-based therapies (Reiki …

De Novo Descending Aorta Thrombus In A Patient With Metastatic Colorectal Cancer: A Case Report, Om Parkash, Adil Ayub, Buria Naeem, Saeed Hamid

Section of Gastroenterology

Thromboembolic events in patients with cancer are frequently reported in literature and usually involve the venous circulation. De novo thrombus formation in the arterial system without any underlying atherosclerosis, dissection or aneurysm is extremely rare. We report the case of a patient with metastatic colorectal carcinoma who developed a thrombus in the descending aorta without any intervention or risk factors. The patient presented with non-specific gastrointestinal symptoms. A CT scan revealed an aortic thrombus obstructing 70% of the lumen. She opted for no treatment of her thrombus and was later complicated by extensive lower limb emboli. Patients with aortic thrombosis …

Giardina, Cleo Robinson, Muhammad A. Khattak, Tarek M. Meniawy, Antonia L. Pritchard, Nicholas K. Hayward, Benhur Amanuel, Michael J. Millward, Mel R. Ziman Dr, Elin S. Gray

Research outputs 2014 to 2021

Background:

Currently mainly BRAF mutant circulating tumor DNA (ctDNA) is utilized to monitor patients with melanoma. TERT promoter mutations are common in various cancers and found in up to 70 % of melanomas, including half of BRAF wildtype cases. Therefore, a sensitive method for detection of TERT promoter mutations would increase the number of patients that could be monitored through ctDNA analysis.

Methods:

A droplet digital PCR (ddPCR) assay was designed for the concurrent detection of chr5:1,295,228 C > T and chr5:1,295,250 C > T TERT promoter mutations. The assay was validated using 39 melanoma cell lines and 22 matched plasma and …

Investigating The Synergistic Effects Of Cisplatin And Two Curcuminoid Compounds On Cancer, Denis Hodzic

Mahurin Honors College Capstone Experience/Thesis Projects

Cisplatin is an anti-cancer drug effective against several cancers which can produce the serious side-effect of hearing loss. Curcumin, a natural plant compound, can increase the activity of cisplatin against cancer and counteract cisplatin’s effect against hearing. Because curcumin exhibits poor bioavailability, there is considerable interest in developing synthetic curcumin analogs (curcuminoids) that are more soluble and which retain anti-cancer activity and otoprotective function. This study investigated whether two curcuminoids, EF-24 and CLEFMA, increase the cytotoxic and ototoxic effects of cisplatin against the lung cancer cell line, A549, and the colorectal cancer cell line, Caco2. Cytotoxicity was measured by using …

Current Trends In Cancer Support Within The Religious Community, Ched E. Spellman, Luke M. Tse, Andrew W. Wonders, Karen Wonders, Brittany Stout

Biblical and Theological Studies Faculty Publications

Living with cancer is associated with significant psychological strain. The prevalence and severity of this distress varies according to the time, type, and stage of cancer, as well as other variables including treatment regimen, side effects, and prognosis. More often than not, these struggles are neglected as part of the traditional cancer care plan. Yet, if left unaddressed, emotional strain can add to the suffering caused by cancer by negatively affecting treatment compliance. Faith communities, such as churches, provide an ideal atmosphere to serve and support individuals battling cancer. However, research indicates that spiritual care is often a neglected component …

Exploring Cancer Metabolism Using Stable Isotope-Resolved Metabolomics (Sirm), Ronald C. Bruntz, Andrew N. Lane, Richard M. Higashi, Teresa W. -M. Fan

Center for Environmental and Systems Biochemistry Faculty Publications

Metabolic reprogramming is a hallmark of cancer. The changes in metabolism are adaptive to permit proliferation, survival, and eventually metastasis in a harsh environment. Stable isotope-resolved metabolomics (SIRM) is an approach that uses advanced approaches of NMR and mass spectrometry to analyze the fate of individual atoms from stable isotope-enriched precursors to products to deduce metabolic pathways and networks. The approach can be applied to a wide range of biological systems, including human subjects. This review focuses on the applications of SIRM to cancer metabolism and its use in understanding drug actions.

Clinical and Translational Science Institute

In this report we utilized zebrafish (Danio rerio) embryos in a phenotypical high-content screen (HCS) to identify novel leads in a cancer drug discovery program. We initially validated our HCS model using the flavin adenosine dinucleotide (FAD) containing endoplasmic reticulum (ER) enzyme, endoplasmic reticulum oxidoreductase (ERO1) inhibitor EN460. EN460 showed a dose response effect on the embryos with a dose of 10 μM being significantly lethal during early embryonic development. The HCS campaign which employed a small library identified a promising lead compound, a naphthyl-benzoic acid derivative coined compound 1 which had significant dosage and temporally dependent effects on notochord …

Ultrasound Monitoring Of Extant Adnexal Masses In The Era Of Type 1 And Type 2 Ovarian Cancers: Lessons Learned From Ovarian Cancer Screening Trials, Eleanor L. Ormsby, Edward J. Pavlik, John P. Mcgahan

Obstetrics and Gynecology Faculty Publications

Women that are positive for an ovarian abnormality in a clinical setting can have either a malignancy or a benign tumor with probability favoring the benign alternative. Accelerating the abnormality to surgery will result in a high number of unnecessary procedures that will place cost burdens on the individual and the health delivery system. Surveillance using serial ultrasonography is a reasonable alternative that can be used to discover if changes in the ovarian abnormality will occur that favor either a malignant or benign interpretation. Several ovarian cancer screening trials have had extensive experiences with changes in subclinical ovarian abnormalities in …

Included in these considerations are: (1) Deciding on the number of individuals to be screened; (2) Anticipating screening group reductions due to death; (3) Deciding on the duration and frequency of screening; (4) Deciding on an appropriate follow-up period after screening; (5) Deciding on time to surgery when malignancy is suspected; (6) Deciding on how screen-detected ovarian cancers are treated and by whom; (7) Deciding on how to treat the data of enrolled participants; (8) Deciding on the most …

Gastrointestinal Stromal Tumor Induced Hypercalcemia, Aram Barbaryan, Stefania Bailuc, Padma Poddutoori, Aida Richardson, Aibek E. Mirrakhimov

Internal Medicine Faculty Publications

Hypercalcemia in patients with cancer is a common laboratory finding affecting up to 44% of that patient population. 1,25-Dihydroxyvitamin D₃ mediated hypercalcemia is one of the rare mechanisms of this endocrine emergency in cancer patients. It is even rarer for solid organ neoplasms to present with hypercalcemia mediated through the production of 1,25-dihydroxyvitamin D₃. We report a case of a 77-year-old female who presented to the hospital with hypercalcemia and later was found to have metastatic gastrointestinal stromal tumor. There have been only 5 cases of gastrointestinal stromal tumor described in literature resulting in hypercalcemia. In our …
