Brg1 Is A Prognostic Indicator And A Potential Therapeutic Target For Prostate Cancer, Rohini Muthuswami, Leeann Bailey, Radhakrishnan Rakesh, Anthony N. Imbalzano, Jeffrey A. Nickerson, Joel W. Hockensmith

University of Massachusetts Medical School Faculty Publications

Brahma-related gene 1 (BRG1) is one of two mutually exclusive ATPases that function as the catalytic subunit of human SWItch/Sucrose NonFermentable (SWI/SNF) chromatin remodeling enzymes. BRG1 has been identified as a tumor suppressor in some cancer types but has been shown to be expressed at elevated levels, relative to normal tissue, in other cancers. Using TCGA (The Cancer Genome Atlas) prostate cancer database, we determined that BRG1 mRNA and protein expression is elevated in prostate tumors relative to normal prostate tissue. Only 3 of 491 (0.6%) sequenced tumors showed amplification of the locus or mutation in the ...


Is A Varicocelectomy Beneficial In The Era Of Assisted Reproductive Technologies, Chukwuka Oscar Nnoli 2019 University of North Dakota

Is A Varicocelectomy Beneficial In The Era Of Assisted Reproductive Technologies, Chukwuka Oscar Nnoli

Physician Assistant Scholarly Project Posters

Clinical varicoceles are the most frequent physical finding associated with infertile men and impaired semen parameters. There is evidence that suggests varicocele repair improves semen parameter and increases the chances of natural pregnancy. Today, varicocele repair is often combined with assisted reproductive techniques (ART) such as intrauterine insemination (IUI), in Vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI). In this literature review, data examining whether varicocelectomy before ART leads to improved pregnancy outcomes is reviewed. Current data suggest that there is a significant clinical benefit when correcting a varicocele in oligospermic men before IVF/ICSI. Similarly, men with non-obstructive azoospermia ...


Proteomic Profiling Of Serum Derived Exosomes From Prostate Cancer Patients, David Turay 2018 Selected Works

Proteomic Profiling Of Serum Derived Exosomes From Prostate Cancer Patients, David Turay

David Turay, MD

Touted among the major achievements in the diagnosis and management of Prostate cancer (PCa) in the past few decades has been, the dramatic decline of men with advanced/metastatic PCa at diagnosis coupled with a significant improvement ( >90%) in the five and ten year survival rates of the disease. Non-palpable PCa (potentially clinically treatable disease) now accounts for 70-80% of all newly diagnosed cases of PCa. Preceding these changes by about a decade was the introduction of Prostatic Specific Antigen (PSA) into clinical practice; first as biomarker for monitoring response to therapy and subsequently as a complementary screening tool. It ...


Both Maternal And Paternal Risk Factors For Term Singleton Low Birthweight Infants In Rural Chinese Population: A Population-Based, Retrospective Cohort Study, Shi Chen, Bill Q. Lian, Hui Pan 2018 Peking Union Medical College

Both Maternal And Paternal Risk Factors For Term Singleton Low Birthweight Infants In Rural Chinese Population: A Population-Based, Retrospective Cohort Study, Shi Chen, Bill Q. Lian, Hui Pan

Open Access Articles

No large population-based study has focused on both maternal paternal risk factors for low birthweight (LBW) in China. We aimed to identify parental risk factors associated with LBW. A population-based, retrospective cohort study was conducted on 202,725 singleton infants at 37-42 weeks. These term singleton newborns were classified as LBW with birthweight < /=2500 g(TLBW) and normal birthweight between 50(th) to 97(th) percentile (TNBW 50(th)-97(th)) according to Chinese singleton norms. Multiple logistic regression analyses were used to find those parental risk factors of LBW by comparing two groups. TLBW and TNBW(50(th)-97(th)) occupied 4.8% and 70.8% of the study population, respectively. Logistic regression showed a significant association with positive maternal hepatitis B surface antigen (RR = 1.979, P = 0.047), irregular folic acid intake (RR = 1.152, P = 0.003), paternal history of varicocele (RR = 2.404, P = 0.003) and female babies (RR = 1.072, P = 0.046). Maternal smoking, hypertension and history of stillbirth were found related to LBW but no statistically significant. Positive maternal hepatitis B surface antigen, irregular folic acid intake, paternal history of varicocele had a negative effect on birth weight. Measures are necessarily taken to avoid them to improve pregnancy outcomes. Further studies should be done to investigate each detailed risk factors on LBW.


Changes In The Testes Following Spinal Cord Injury And The Attenuating Effects Of Licofelone, Ryan Fortune 2018 The University of Texas M D Anderson Cancer Center UTHealth Graduate School of Biomedical Sciences

Changes In The Testes Following Spinal Cord Injury And The Attenuating Effects Of Licofelone, Ryan Fortune

The University of Texas MD Anderson Cancer Center UTHealth Graduate School of Biomedical Sciences Dissertations and Theses (Open Access)

Spinal cord injury is a devastating disease that researchers have had very limited success in treating. In addition to interrupted innervation, spinal cord injury causes pathologic changes in a multitude of organ systems. Male infertility is one such complication that is particularly devastating because the patient population is predominantly young men. Our lab has previously shown that the blood testis barrier breaks down after spinal cord injury. This dissertation shows the local metabolomic and mRNA changes that spinal cord injury causes within the testes using a Sprague Dawley rat model, including the elevation in eicosanoids, increased oxidative stress, chronically elevated ...

Neisseria gonorrhoeae is a bacterial pathogen responsible for the sexually transmitted infection gonorrhea. Emergence of antimicrobial resistance (AMR) of N. gonorrhoeae worldwide has resulted in limited therapeutic choices for this infection. Men who seek treatment often have symptomatic urethritis; in contrast, gonococcal cervicitis in women is usually minimally symptomatic, but may progress to pelvic inflammatory disease. Previously, we reported the first analysis of gonococcal transcriptome expression determined in secretions from women with cervical infection. Here, we defined gonococcal global transcriptional responses in urethral specimens from men with symptomatic urethritis and compared these with transcriptional responses in specimens obtained from women ...


Characterization Of Human Prostate Cancer Using Sodium Magnetic Resonance Imaging, Nolan Christopher Broeke 2018 The University of Western Ontario

Characterization Of Human Prostate Cancer Using Sodium Magnetic Resonance Imaging, Nolan Christopher Broeke

Electronic Thesis and Dissertation Repository

Overtreatment of prostate cancer is a significant problem in the health care of men. Development of non-invasive imaging tools for improved characterization of prostate lesions has the potential to reduce overtreatment. In this thesis work, we will evaluate the ability of tissue sodium concentration obtained from sodium magnetic resonance imaging (sodium-MRI) to characterize in vivo prostate lesions. Imaging data, including multi-parametric magnetic resonance imaging (mpMRI) and sodium-MRI, were obtained from a cohort of men with biopsy-proven prostate cancer and compared to digitized whole-mount histopathology after prostatectomy. Histopathology was independently graded for Gleason score to be used as the ground truth ...


Regulation Of The Pi3-Kinase/Pten Signaling Pathway By Tgf-Β In Prostate Cancer Cells, Mawiyah Kimbrough-Allah 2018 Atlanta University Center

Regulation Of The Pi3-Kinase/Pten Signaling Pathway By Tgf-Β In Prostate Cancer Cells, Mawiyah Kimbrough-Allah

Electronic Theses & Dissertations Collection for Atlanta University & Clark Atlanta University

Transforming growth factor -β (TGF-β) plays an important role in the progression of prostate cancer. It acts as a tumor suppressor in normal epithelial cells but as a tumor promoter in advanced prostate cancer cells. The PI3-kinase pathway has been shown to play integral roles in many cellular processes including cell proliferation, survival, and cell migration in many cell types. PI3-kinase pathway mediates TGF-β effects on prostate cancer cell migration and invasion. Phosphatase and tensin homolog (PTEN), a tumor suppressor gene, inhibits PI3-kinase pathway and is frequently mutated in prostate cancers. In this present study, we investigated possible roles of ...


Elucidation Of The Functions Of Neuropilin 2 In Osteoclasts In Promoting Prostate Cancer Bone Metastasis., Navatha S. Polavaram 2018 University of Nebraska Medical Center

Elucidation Of The Functions Of Neuropilin 2 In Osteoclasts In Promoting Prostate Cancer Bone Metastasis., Navatha S. Polavaram

Theses & Dissertations

Bone metastasis is one of the major clinical concerns that causes skeletal related malignancies and increased mortality. Bone is one of the preferred sites for metastatic prostate cancer. The metastatic prostate cancer cells interact with bone cells (osteoblasts and osteoclasts) resulting in an imbalance in the bone homeostasis leading to increased activation of osteoblasts over osteoclasts. Our preliminary data indicated a non-tyrosine kinase receptor Neuropilin 2 (NRP2) is expressed in osteoclasts induced by metastatic prostate cancer cells and acts as a negative regulator of osteoclast differentiation and function. We hypothesize that prostate cancer -induced NRP2 expression in osteoclasts is necessary ...

Outcomes Of Genetic Testing In A Genitourinary Genetics Clinic, Annelise Pace

The University of Texas MD Anderson Cancer Center UTHealth Graduate School of Biomedical Sciences Dissertations and Theses (Open Access)

Several known hereditary cancer syndromes confer an increased risk for genitourinary (GU)related malignancies. Various guidelines indicate when to refer patients to genetic counseling for GU-related hereditary cancer syndromes but there is limited research on the clinical picture of these patients, including their cancerous and non-cancerous features, the genetic testing strategy for this population, and the probability of having a positive germline mutation if testing is performed. The purpose of this study is to determine the most common indications for ordering genetic testing in a GU Genetics Clinic and evaluate whether there is a relationship between the indication for genetic ...

Microrna 1207-3p In Prostate Cancer, Dibash Das

All Dissertations, Theses, and Capstone Projects

Prostate cancer (PCa) is the most commonly diagnosed male cancer and the second leading cause of cancer-related death for men in the United States. Understanding the molecular mechanisms involved in progression from the asymptomatic androgen-dependent PCa to the lethal castration resistant prostate cancer (CRPC) is a major challenge. MicroRNAs (miRNAs), are known to be dysregulated in PCa. MicroRNA-1207-3p (miR-1207-3p) is encoded by the non-protein coding gene locus PVT1 on the 8q24 human chromosomal region, an established PCa susceptibility locus. However, the role of miR-1207-3p in PCa is unclear. We have discovered that miR-1207-3p is significantly underexpressed in PCa cell lines ...


Prostate Cancer Screening Guidelines: Providing Patient Education, Michael Burton 2018 University of Vermont

Prostate Cancer Screening Guidelines: Providing Patient Education, Michael Burton

Family Medicine Clerkship Student Projects

The United States Preventative Services Task Force (USPSTF) is planning to update their prostate cancer PSA screening guidelines to a category C from category D grade. This could potentially lead to confusion among both providers and patients as they have become accustomed to the previous guidelines and there has always been much discussion among providers about whether to offer the test. This project seeks to provide information to patients about the upcoming change so that they are more informed and able to better participate in discussion with their doctor about the pros and cons of PSA testing.


Cellular And Molecular Basis Of Equine Arteritis Virus Persistent Infection In The Stallion Reproductive Tract: Characterization Of Local Host-Pathogen Interactions Mediating Long-Term Viral Persistence, Mariano Carossino 2018 University of Kentucky

Cellular And Molecular Basis Of Equine Arteritis Virus Persistent Infection In The Stallion Reproductive Tract: Characterization Of Local Host-Pathogen Interactions Mediating Long-Term Viral Persistence, Mariano Carossino

Theses and Dissertations--Veterinary Science

Equine arteritis virus (EAV) has a global impact on the equine industry being the causative agent of equine viral arteritis (EVA), a reproductive, respiratory, and systemic disease of equids. A distinctive feature of EAV infection is that it establishes long-term persistent infection in the reproductive tract of stallions and is continuously shed in the semen (carrier state). Recent studies showed that long-term persistence is associated with a specific allele of the CXCL16 gene (CXCL16S). However, the cellular and molecular mechanisms underlying the establishment and maintenance of persistent infection are yet to be determined. The studies were undertaken herein unequivocally demonstrated ...

Buffart, Robert U. Newton, Nigel Spry, James Denham, David Joseph, David Lamb, Suzanne K. Chambers, Daniel A. Galvao

ECU Publications Post 2013

Objectives

To explore if duration of previous exposure to androgen deprivation therapy (ADT) in men with prostate cancer (PCa) undertaking a year-long exercise programme moderates the exercise response with regard to body composition and muscle performance, and also to explore the moderator effects of baseline testosterone, time since ADT, and baseline value of the outcome.

Patients and Methods

In a multicentre randomized controlled trial, 100 men who had previously undergone either 6 months (short-term) or 18 months (long-term) of ADT in combination with radiotherapy, as part of the TROG 03.04 RADAR trial, were randomized to 6 months supervised exercise ...


Novel Therapeutic Strategies For Treatment Of Castration-Resistant Prostate Cancer, Matthew A. Ingersoll 2017 University of Nebraska Medical Center

Novel Therapeutic Strategies For Treatment Of Castration-Resistant Prostate Cancer, Matthew A. Ingersoll

Theses & Dissertations

Prostate cancer (PCa) remains the most commonly diagnosed solid tumor and is the third leading cause of cancer-related death in United States men. While androgen deprivation therapy is the current standard-of-care treatment for metastatic PCa, most patients eventually relapse and develop castration-resistant (CR) tumors, for which there is currently no effective treatment. Therefore, synthesis of novel therapeutic agents and identification of alternative target proteins are necessary to improve treatment. Herein, I investigate the efficacy of novel imidazopyridine and statin derivatives as alternative therapeutic compounds. These molecules not only inhibit androgen receptor signaling, but also block activation of the AKT axis ...

Stat3 And Stat5a Are Potential Therapeutic Targets In Castration-Resistant Prostate Cancer, Sambit K. Mohanty, Kader Yagiz, Dinesh Pradhan, Daniel J. Luthringer, Mahul B. Amin, Serhan Alkan, Bekir Cinar 2017 Cedars-Sinai Medical Center

Stat3 And Stat5a Are Potential Therapeutic Targets In Castration-Resistant Prostate Cancer, Sambit K. Mohanty, Kader Yagiz, Dinesh Pradhan, Daniel J. Luthringer, Mahul B. Amin, Serhan Alkan, Bekir Cinar

Clark Atlanta University Faculty Publications

Mechanisms of castration-resistant prostate cancer (CRPC) are not well understood, thus hindering rational-based drug design. Activation of STAT3/5A, key components of the JAK/STAT pathway, is implicated in aggressive PC, yet their clinical relevance in CRPC remains elusive. Here, we evaluated the possible role of STAT3/5A in CRPC using immunological, quantitative mRNA expression profiling, and pharmacological methods. We observed a strong nuclear immunoreactivity for STAT3 and STAT5A in 93% (n=14/15) and 80% (n=12/15) of CRPC cases, respectively, compared with benign prostatic hyperplasia (BPH). We demonstrated that PC cells express varying levels of STAT3 and ...

Mapping The Stk4/Hippo Signaling Network In Prostate Cancer Cell, Damien Ready, Kader Yagiz, Pooneh Amin, Yuksel Yildiz, Vincent Funari, Seardar Bozdag, Bekir Cinar

Clark Atlanta University Faculty Publications

Dysregulation of MST1/STK4, a key kinase component of the Hippo-YAP pathway, is linked to the etiology of many cancers with poor prognosis. However, how STK4 restricts the emergence of aggressive cancer remains elusive. Here, we investigated the effects of STK4, primarily localized in the cytoplasm, lipid raft, and nucleus, on cell growth and gene expression in aggressive prostate cancer. We demonstrated that lipid raft and nuclear STK4 had superior suppressive effects on cell growth in vitro and in vivo compared with cytoplasmic STK4. Using RNA sequencing and bioinformatics analysis, we identified several differentially expressed (DE) genes that responded to ...
