BRD4 assembles transcriptional machinery at gene super-enhancer regions and governs the expression of genes that are critical for cancer progression. However, it remains unclear whether BRD4-mediated gene transcription is required for tumor cells to develop drug resistance. Our data show that prolonged treatment of luminal breast cancer cells with AKT inhibitors induces FOXO3a dephosphorylation, nuclear translocation, and disrupts its association with SirT6, eventually leading to FOXO3a acetylation as well as BRD4 recognition. Acetylated FOXO3a recognizes the BD2 domain of BRD4, recruits the BRD4/RNAPII complex to the CDK6 gene promoter, and induces its transcription. Pharmacological inhibition of either BRD4/FOXO3a association or …

The project analyzed and compared the differences in cancer screenings for colorectal, breast, and cervical cancer among those currently diagnosed with a mental condition and the general population. Through p-value and Pearson chi-square statistical analysis of the Community Health Data Base …

Collagen Prolyl 4-Hydroxylase 1 Is Essential For Hif-1Α Stabilization And Tnbc Chemoresistance, Gaofeng Xiong, Rachel L. Stewart, Jie Chen, Tianyan Gao, Timothy L. Scott, Luis M. Samayoa, Kathleen L. O'Connor, Andrew N. Lane, Ren Xu

Markey Cancer Center Faculty Publications

Collagen prolyl 4-hydroxylase (P4H) expression and collagen hydroxylation in cancer cells are necessary for breast cancer progression. Here, we show that P4H alpha 1 subunit (P4HA1) protein expression is induced in triple-negative breast cancer (TNBC) and HER2 positive breast cancer. By modulating alpha ketoglutarate (α-KG) and succinate levels P4HA1 expression reduces proline hydroxylation on hypoxia-inducible factor (HIF) 1α, enhancing its stability in cancer cells. Activation of the P4HA/HIF-1 axis enhances cancer cell stemness, accompanied by decreased oxidative phosphorylation and reactive oxygen species (ROS) levels. Inhibition of P4HA1 sensitizes TNBC to the chemotherapeutic agent docetaxel and doxorubicin in xenografts and patient-derived …

P-21 Activated Kinase As A Molecular Target For Chemoprevention In Diabetes, Kyle Dammann, Vineeta Khare, Clyde Coleman, Henrik Berdel, Christoph Gasche

Surgery Faculty Publications

Hypothesis: Anti-diabetic drugs modulate p-21 activated kinase (PAK) signaling. Introduction: Type 2 diabetes mellitus (T2DM) is a chronic inflammatory disease associated with increased cancer risk. PAK signaling is implicated in cellular homeostasis when regulated, and cancer when unrestrained. Recent reports provided a role for PAK signaling in glucose homeostasis, but the role of PAKs in the pathogenesis of T2DM is unknown. Here, we performed a mini-meta-analysis to explore if anti-diabetic drugs modify PAK signaling pathways, and provide insight regarding modulation of these pathways, to potentially reduce diabetes-associated cancer risk. Methods: PAK interacting partners in T2DM were identified using the online …

Oxytocin And Cancer: An Emerging Link, Ben Lerman, Trisheena Harricharran, Olorunseun O. Ogunwobi

Publications and Research

The neuropeptide hormone oxytocin, which is released from the posterior pituitary gland, is involved in a number of physiological processes. Understanding of its effects is gradually increasing due to new research in this area. While mostly recognized as a reproductive system hormone, oxytocin also regulates other organ systems such as the brain and cardiovascular system. Recently, research has focused on unraveling its involvement in cancer, and emerging evidence suggests a potential role for oxytocin as a cancer biomarker. This review summarizes observations linking oxytocin and cancer, with a special emphasis on prostate cancer, where it may promote cell proliferation. Research …

Unleashing Endogenous Tnf-Alpha As A Cancer Immunotherapeutic., Steven F Josephs, Thomas E Ichim, Stephen M Prince, Santosh Kesari, Francesco M Marincola, Anton Rolando Escobedo, Amir Jafri

Articles, Abstracts, and Reports

Tumor necrosis factor (TNF)-alpha was originally identified in the 1970s as the serum mediator of innate immunity capable of inducing hemorrhagic necrosis in tumors. Today, a wide spectrum of biological activities have been attributed to this molecule, and clinical translation has mainly occurred not in using it to treat cancer, but rather to inhibit its effects to treat autoimmunity. Clinical trials utilizing systemic TNF-alpha administration have resulted in an unacceptable level of toxicities, which blocked its development. In contrast, localized administration of TNF-alpha in the form of isolated limb perfusion have yielded excellent results in soft tissue sarcomas. Here we …

Role Of Multi-Parametric (Mp) Mri In Prostate Cancer, Syed Muhammad Nazim, Ather Enam, Basit Salam

Section of Urology

Multi-parametric magnetic resonance imaging is increasingly being recommended as standard imaging modality for prostate cancer diagnosis and staging. It comprises structural T2 and T1 sequences supplemented by functional imaging techniques, i.e. diffusion-weighted, dynamic contrast enhanced and spectroscopic imaging. Pre-biopsy multi-parametric magnetic resonance imaging is recommended for both detection and staging as it avoids biopsy artefact, and when normal, has a negative predictive value of 95% for significant cancer. Magnetic resonance imaging-guided prostate biopsy targets only area(s) considered to be suspicious for prostate cancer, hence resulting in improved accuracy. Dynamic contrast enhancing helps in the detection of cancer and for the …

“Do We Know Jack” About Jak? A Closer Look At Jak/Stat Signaling Pathway, Emira Bousoik, Hamidreza Montazeri Aliabadi

Pharmacy Faculty Articles and Research

Janus tyrosine kinase (JAK) family of proteins have been identified as crucial proteins in signal transduction initiated by a wide range of membrane receptors. Among the proteins in this family JAK2 has been associated with important downstream proteins, including signal transducers and activators of transcription (STATs), which in turn regulate the expression of a variety of proteins involved in induction or prevention of apoptosis. Therefore, the JAK/STAT signaling axis plays a major role in the proliferation and survival of different cancer cells, and may even be involved in resistance mechanisms against molecularly targeted drugs. Despite extensive research focused on the …

There are numerous downstream consequences of marketed drugs like antineoplastic agents on the gut microbiome, an effect that is suggested to contribute to adverse event profiles and may also influence drug responses. In cancer, progress is needed toward modulation of the host microbiome to prevent off-target side effects of drugs such as gastrointestinal mucositis that result from gut dysbiosis. The objective of this study was evaluation of the bioactivity of a supplement consisting of capsules with a blend of 9 probiotic organisms of the genera

Recurrent Tumor-Specific Regulation Of Alternative Polyadenylation Of Cancer-Related Genes., Zhuyi Xue, René L Warren, Ewan A Gibb, Daniel Macmillan, Johnathan Wong, Readman Chiu, S Austin Hammond, Chen Yang, Ka Ming Nip, Catherine A Ennis, Abigail Hahn, Sheila Reynolds, Inanc Birol

Articles, Abstracts, and Reports

BACKGROUND: Alternative polyadenylation (APA) results in messenger RNA molecules with different 3' untranslated regions (3' UTRs), affecting the molecules' stability, localization, and translation. APA is pervasive and implicated in cancer. Earlier reports on APA focused on 3' UTR length modifications and commonly characterized APA events as 3' UTR shortening or lengthening. However, such characterization oversimplifies the processing of 3' ends of transcripts and fails to adequately describe the various scenarios we observe.

RESULTS: We built a cloud-based targeted de novo transcript assembly and analysis pipeline that incorporates our previously developed cleavage site prediction tool, KLEAT. We applied this pipeline to …

Exploring The Excluded Stomach: A Case Series Of Novel Endoscopic Techniques To Diagnose Gastric Cancer In The Excluded Stomach After Roux-En-Y Gastric Bypass Surgery, Saeed Ali, Abdelkader Chaar, Wesam Frandah, Rola Altoos, Zeeshan Sattar, Muhammad Hasan

Internal Medicine

Gastric cancer is the fifth most common malignancy worldwide and the fourth leading cause of cancer-related deaths. The diagnosis is usually made by direct visualization with supporting histopathology. However, patients with gastric bypass surgery pose a challenge in diagnosis due to the difficulty in the evaluation of the excluded stomach. We present two cases of gastric cancer in the excluded stomach after Roux-en-Y gastric bypass (RYGB) surgery was diagnosed using two different endoscopic approaches.

Digitizing Omics Profiles By Divergence From A Baseline., Wikum Dinalankara, Qian Ke, Yiran Xu, Lanlan Ji, Nicole Pagane, Anching Lien, Tejasvi Matam, Elana J Fertig, Nathan D Price, Laurent Younes, Luigi Marchionni, Donald Geman

Articles, Abstracts, and Reports

Data collected from omics technologies have revealed pervasive heterogeneity and stochasticity of molecular states within and between phenotypes. A prominent example of such heterogeneity occurs between genome-wide mRNA, microRNA, and methylation profiles from one individual tumor to another, even within a cancer subtype. However, current methods in bioinformatics, such as detecting differentially expressed genes or CpG sites, are population-based and therefore do not effectively model intersample diversity. Here we introduce a unified theory to quantify sample-level heterogeneity that is applicable to a single omics profile. Specifically, we simplify an omics profile to a digital representation based on the omics profiles …

Investigating The Synergistic Effects Of Two Curcuminoids And Cisplatin On Cancer Cell Migration, Blaine Patty

Mahurin Honors College Capstone Experience/Thesis Projects

Cisplatin is a common chemotherapy drug used to treat various cancers; however, it is relatively ineffective against many cancers, including several types of lung cancer. One approach that could improve cisplatin’s effect is to combine it with another drug that produces a synergistic response greater than either drug alone. Curcumin, a naturally occurring plant compound, has been investigated for synergisms in conjunction with cisplatin chemotherapy, but curcumin use is hampered by its low bioavailability. This project investigated whether two synthetic curcumin analogs, EF-24 and CLEFMA (curcuminoids), which have greater solubility than curcumin, could, when combined with cisplatin, decrease the migration …

Investigating The Synergistic Effects Of Two Curcuminoids And Cisplatin On Cancer Cell Reactive Oxygen Species, Matthew Millay

Mahurin Honors College Capstone Experience/Thesis Projects

Cisplatin is an anticancer drug which can cause the production of reactive oxygen species (ROS) that kill cancer cells. Curcumin is a naturally occurring plant compound that can increase ROS levels in cancer cells and enhance the activity of cisplatin against cancer, but it exhibits poor bioavailability. We investigated whether two synthetic curcumin analogs (curcuminoids), EF-24 and CLEFMA, with anti-cancer activity and improved bioavailability, increased cisplatin’s effect against cancer. A spectrophotometric fluorescent ROS assay was used to determine if cisplatin, the curcuminoids or combinations of cisplatin with a curcuminoid affected the level of ROS in the A549 non-small cell lung …

Inhibition Of Insulin‐Like Growth Factor 1 Receptor Enhances The Efficacy Of Sorafenib In Inhibiting Hepatocellular Carcinoma Cell Growth And Survival, Fang Wang, Thomas Bank, George Malnassy, Maribel Arteaga, Na Shang, Annika Dalheim, Xianzhong Ding, Scott J. Cotler, Mitchell F. Denning, Michael I. Nishimura, Peter Breslin, Wei Qiu

Biology: Faculty Publications and Other Works

Hepatocellular carcinoma (HCC) is the fifth most common primary cancer and second largest cause of cancer‐related death worldwide. The first‐line oral chemotherapeutic agent sorafenib only increases survival in patients with advanced HCC by less than 3 months. Most patients with advanced HCC have shown limited response rates and survival benefits with sorafenib. Although sorafenib is an inhibitor of multiple kinases, including serine/threonine‐protein kinase c‐Raf, serine/threonine‐protein kinase B‐Raf, vascular endothelial growth factor receptor (VEGFR)‐1, VEGFR‐2, VEGFR‐3, and platelet‐derived growth factor receptor β, HCC cells are able to escape from sorafenib treatment using other pathways that the drug insufficiently inhibits. The aim …

Articles, Abstracts, and Reports

Gene fusions represent an important class of somatic alterations in cancer. We systematically investigated fusions in 9,624 tumors across 33 cancer types using multiple fusion calling tools. We identified a total of 25,664 fusions, with a 63% validation rate. Integration of gene expression, copy number, and fusion annotation data revealed that fusions involving oncogenes tend to exhibit increased expression, whereas fusions involving tumor suppressors have the opposite effect. For fusions involving kinases, we found 1,275 with an intact kinase domain, the proportion of which varied significantly across cancer types. Our study suggests that fusions drive the development of 16.5% of …

In-Hospital Mortality And Post-Surgical Complications Among Cancer Patients With Metabolic Syndrome, Tomi Akinyemiju, Swati Sakhuja, Neomi Vin-Raviv

Epidemiology and Environmental Health Faculty Publications

Background

Metabolic syndrome (MetS) is an important etiologic and prognostic factor for cancer, but few studies have assessed hospitalization outcomes among patients with both conditions.

Methods

Data was obtained from the Healthcare Cost and Utilization project Nationwide Inpatient Sample (HCUP-NIS). Study variables were assessed using ICD-9 codes on adults aged 40 years and over admitted to a US hospital between 2007 and 2011 with primary diagnosis of either breast, colorectal, or prostate cancer. We examined in-hospital mortality, post-surgical complications, and discharge disposition among cancer patients with MetS and compared with non-MetS patients.

Results

Hospitalized breast (OR: 0.31, 95% CI: 0.20–0.46), …

Treatment-Related Mortality In Newly Diagnosed Pediatric Cancer: A Population-Based Analysis., Paul Gibson, Jason D Pole, Tanya Lazor, Donna Johnston, Carol Portwine, Mariana Silva, Sarah Alexander, Lillian Sung

Paediatrics Publications

Using a previously developed reliable and valid treatment-related mortality (TRM) definition, our objective was to describe the proportion of children newly diagnosed with cancer experiencing TRM and to identify risk factors for TRM in a population-based cohort. We included children with cancerincluded, 179 had TRM, 478 died of progressive disease, and 4522 were still alive. At 5 years, the cumulative incidence of TRM among the entire cohort was 3.9% (95% confidence interval (CI) 3.3-4.5%). When compared to brain tumor patients, leukemia and lymphoma patients had a significantly higher risk of TRM (hazard ratio (HR) 2.5, 95% CI: 1.6-4.0; P < 0.0001). Infants were at significantly higher risk of TRM across diagnostic groups. Other factors associated with higher risks of TRM were metastatic disease (P < 0.0001), diagnosis prior to 1 January 2008 (P = 0.001), hematopoietic stem cell transplantation (HSCT) (P < 0.0001), and relapse (P < 0.0001). The 5-year cumulative incidence of TRM was 3.9% among newly diagnosed children with cancer. Infants were at higher risk of TRM across diagnostic groups. Other risk factors for TRM were leukemia or lymphoma, metastatic disease, earlier diagnosis year, HSCT, and relapse. Future work should further refine prognostic factors by specific cancer diagnosis to best understand when and how to intervene to improve outcomes.

A Lin28b Tumor-Specific Transcript In Cancer, Weijie Guo, Zhixiang Hu, Yichao Bao, Yuchen Li, Shengli Li, Qiupeng Zheng, Dongbin Lyu, Di Chen, Tao Yu, Yan Li, Xiaodong Zhu, Jie Ding, Yingjun Zhao, Xianghuo He, Shenglin Huang

Markey Cancer Center Faculty Publications

The diversity and complexity of the cancer transcriptome may contain transcripts unique to the tumor environment. Here, we report a LIN28B variant, LIN28B-TST, which is specifically expressed in hepatocellular carcinoma (HCC) and many other cancer types. Expression of LIN28B-TST is associated with significantly poor prognosis in HCC patients. LIN28B-TST initiates from a de novo alternative transcription initiation site that harbors a strong promoter regulated by NFYA but not c-Myc. Demethylation of the LIN28B-TST promoter might be a prerequisite for its transcription and transcriptional regulation. LIN28B-TST encodes a protein isoform with additional N-terminal amino acids and is critical for cancer …

Emotion Regulation And Positive Affect In The Context Of Salivary Alpha-Amylase Response To Pain In Children With Cancer, Brooke N. Jenkins, Douglas A. Granger, Ryan J. Roemer, Ariana Martinez, Tara K. Torres, Michelle A. Fortier

Psychology Faculty Articles and Research

Background

Children with cancer routinely undergo painful medical procedures invoking strong physiological stress responses. Resilience to this pain may be conferred through resources such as emotion regulation strategies and positive affect.

Procedure

This study measured dispositional positive affect in children with cancer (N = 73) and randomly assigned participants to one of three emotion regulation strategy conditions (distraction, reappraisal, or reassurance). Children applied their assigned strategy during an experimental pain procedure (the cold pressor task [CPT]) and provided saliva samples before, immediately after, and 15 min after the CPT. Saliva samples were later assayed for salivary alpha amylase (sAA)—a surrogate …
