TGF-β inhibits proliferation of prostate epithelial cells. However, prostate cancer cells in advanced stages become resistant to inhibitory effects of TGF-β. The intracellular signaling mechanisms involved in differential effects of TGF-β during different stages are largely unknown. Using cell line models, we have shown that TGF-β inhibits proliferation in normal (RWPE-1) and prostate cancer (DU145) cells but does not have any effect on proliferation of prostate cancer (PC3) cells. We have investigated the role of Jun family proteins (c-Jun, JunB, and JunD) in TGF-β effects on cell proliferation. Jun family members were expressed at different levels and responded differentially to ...

Prostate Cancer In African American Males: Psychological Effects Of Diagnosis And Prostatectomy, M. Rehan Puri, Ernest A. Gbadebo-Goyea, Narviar C. Barker, Rahn Kennedy Bailey

Challenge

Prostate cancer is the most common cancer in men regardless of race or ethnicity, but it is more common in African American men than in white men ( American Cancer Society 2008). It is less common in Hispanic, Asian, Pacific Islander, and Native American men. Several studies have reported diminished and poorer quality of life (i.e., disease-specific physical health and functional status) for African American men who have undergone standard treatments for prostate cancer when compared to white men. However, limited research is available on psychological adjustments to prostate cancer and even less is known about racial differences in psychological ...


Proteomic Profiling Of Serum Derived Exosomes From Prostate Cancer Patients, David Turay 2016 Loma Linda University

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

Loma Linda University Electronic Theses, Dissertations & Projects

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 ...

Meta-analysis of 101 studies published between 1934 and 1996 indicates that mean sperm concentration decreased around 50% during this period. More recent studies have found alarmingly poor semen quality in the general population of Northern Europe. Additional adverse trends include increased incidence of testicular cancer, and congenital malformations such as cryptorchidism and hypospadias. Testicular germ cell cancers increased by about 400% over the period of 50 years in industrialized countries. Decreased quality of male reproductive health has been linked to environmental endocrine disruptors exposure. However, the ability of xenobiotics to produce long-lasting effects and mechanisms of perturbation of the male ...


Analysis Of A Novel Nonsense Mutation Of Androgen Receptor Gene In Castration-Resistant Prostate Cancer, Dong Han, Kevin Valencia, Shuai Gao, Changmeng Cai 2016 University of Massachusetts Boston

Analysis Of A Novel Nonsense Mutation Of Androgen Receptor Gene In Castration-Resistant Prostate Cancer, Dong Han, Kevin Valencia, Shuai Gao, Changmeng Cai

UMass Center for Clinical and Translational Science Research Retreat

BACKGROUND: Prostate cancer (PCa) is the second leading cause of cancer mortality in American men. The standard treatment for PCa is androgen deprivation therapy (ADT) that blocks transcriptional activity of androgen receptor, but ADT invariably leads to the development of castration-resistant form of PCa (CRPC) with restored activity of AR. CRPC can be further treated with more intensive ADTs, including CYP17-inhibitors to block intratumoral androgen synthesis and more potent AR antagonist (enzalutamide). Most CRPC patients still relapse after a year of treatment and AR activity appears to be restored again. By analyzing the tumor mRNA from a CRPC patient biopsy ...

The objectives of our population-based observational study in residents of central Massachusetts were to describe decade-long trends (1999-2009) in the characteristics, in-hospital management, and hospital outcomes of AMI patients with and without these comorbidities.

METHODS: We reviewed the medical records of 6,018 persons who were hospitalized for AMI on a biennial basis between 1999 and 2009 at all ...


Evaluating Use Of Higher Dose Oxybutynin In Combination With Desmopressin For Refractory Nocturnal Enuresis, Aaron Berkenwald, Jacqueline Pires, Pamela Ellsworth 2016 University of Massachusetts Medical School

Evaluating Use Of Higher Dose Oxybutynin In Combination With Desmopressin For Refractory Nocturnal Enuresis, Aaron Berkenwald, Jacqueline Pires, Pamela Ellsworth

Senior Scholars Program

Background: Nocturnal enuresis is a common pediatric condition with limited treatment options. In older children, pharmacologic therapy is often the preferred treatment. Pharmacologic therapies including Desmopressin (DDAVP) or Imipramine are effective in 40-50% of children. However Imipramine has serious safety concerns. DDAVP in combination with a fixed dose anticholinergic has been shown to be useful in individuals who fail DDAVP monotherapy, but still fails to achieve success rates greater than 60%.

Objective: Our goal is to explore the efficacy and safety of using combination therapy DDAVP plus Oxybutynin with increasing dose ofOxybutynin in patients refractory to standard combination therapy.

Medical Help-Seeking For Sexual Concerns In Prostate Cancer Survivors, Melissa K. Hyde, Leah Zajdlewicz, Addie C. Wootten, Christian J. Nelson, Anthony Lowe, Jeff Dunn, Suzanne K. Chambers

ECU Publications Post 2013

Introduction: Although sexual dysfunction is common after prostate cancer, men's decisions to seek help for sexual concerns are not well understood.

Aim: Describe predictors of actual prior help-seeking and intended future medical help-seeking for sexual dysfunction in prostate cancer survivors.

Methods: A cross-sectional survey of 510 prostate cancer survivors assessed masculine beliefs, attitudes, support/approval from partner/peer networks (subjective norm), and perceived control as predictors of medical help-seeking for sexual concerns. A theory of planned behavior (TPB) perspective was used to examine actual prior and planned future behavior and contributing factors. Statistical analyses included multiple and logistic regressions ...

Disorders of sexual development (DSD) encompass a broad spectrum of urogenital malformations and are amongst the most common congenital birth defects. Although key genetic factors such as the hedgehog (Hh) family have been identified, a unifying postnatally viable model displaying the spectrum of male and female urogenital malformations has not yet been reported. Since human cases are diagnosed and treated at various stages postnatally, equivalent mouse models enabling analysis at similar stages are of significant interest. Additionally, all non-Hh based genetic models investigating DSD display normal females, leaving female urogenital development largely unknown. Here, we generated compound mutant mice, Gli2 ...

Prostate cancer (PCa) is the most commonly diagnosed cancer as well as the greatest source of cancer-related mortality in males of African ancestry (MoAA). Interestingly, this has been shown to be associated with single nucleotide polymorphisms around regions 2 and 3 of the 8q24 human chromosomal region. The non-protein coding gene locus Plasmacytoma Variant Translocation 1 (PVT1) is located at 8q24 and is overexpressed in PCa and, therefore, is also a candidate biomarker to explain the well-known disparity in this group. PVT1 has at least 12 exons that make separate transcripts which may have different functions, all of which are ...

Erbeta Regulation Of Nf-Kb Activation In Prostate Cancer Is Mediated By Hif-1, Paul Mak, Jiarong Li, Sanjoy Samanta, Arthur M. Mercurio 2015 University of Massachusetts Medical School

Erbeta Regulation Of Nf-Kb Activation In Prostate Cancer Is Mediated By Hif-1, Paul Mak, Jiarong Li, Sanjoy Samanta, Arthur M. Mercurio

Arthur M. Mercurio

We examined the regulation of NF-kappaB in prostate cancer by estrogen receptor beta (ERbeta) based on the inverse correlation between p65 and ERbeta expression that exists in prostate carcinomas and reports that ERbeta can inhibit NF-kappaB activation, although the mechanism is not known. We demonstrate that ERbeta functions as a gate-keeper for NF-kappaB p65 signaling by repressing its expression and nuclear translocation. ERbeta regulation of NF-kappaB signaling is mediated by HIF-1. Loss of ERbeta or hypoxia stabilizes HIF-1alpha, which we found to be a direct driver of IKKbeta transcription through a hypoxia response element present in the promoter of the ...

Current Opinion In The Role Of Testosterone In The Development Of Prostate Cancer: A Dynamic Model, Xiaohui Xu, Xinguang Chen, Hui Hu, Amy B. Dailey, Brandie D. Taylor 2015 Texas A&M Health Science Center

Current Opinion In The Role Of Testosterone In The Development Of Prostate Cancer: A Dynamic Model, Xiaohui Xu, Xinguang Chen, Hui Hu, Amy B. Dailey, Brandie D. Taylor

Health Sciences Faculty Publications

Background: Since the landmark study conducted by Huggins and Hodges in 1941, a failure to distinguish between the role of testosterone in prostate cancer development and progression has led to the prevailing opinion that high levels of testosterone increase the risk of prostate cancer. To date, this claim remains unproven.

Presentation of the Hypothesis: We present a novel dynamic mode of the relationship between testosterone and prostate cancer by hypothesizing that the magnitude of age-related declines in testosterone, rather than a static level of testosterone measured at a single point, may trigger and promote the development of prostate cancer.

The Ahr Ligand, Tcdd, Regulates Androgen Receptor Activity Differently In Androgen-Sensitive Versus Castration-Resistant Human Prostate Cancer Cells, Maryam Ghotbaddini, Joann B. Powell

Clark Atlanta University Faculty Publications

The reported biological effects of TCDD include induction of drug metabolizing enzymes, wasting syndrome and tumor promotion. TCDD elicits most of its effects through binding the aryl hydrocarbon receptor (AhR). TCDD induced degradation of AhR has been widely reported and requires ubiquitination of the protein. The rapid depletion of AhR following TCDD activation serves as a mechanism to modulate AhR mediated gene induction. In addition to inducing AhR degradation, TCDD has been reported to induce degradation of hormone receptors. The studies reported here, evaluate the effect of TCDD exposure on androgen receptor (AR) expression and activity in androgen-sensitive LNCaP and ...

Prostate cancer (PCa) is the second leading cause of cancer-related death afflicting United States males. Most treatments to-date for metastatic PCa include androgen-deprivation therapy and second-generation anti-androgens such as abiraterone acetate and enzalutamide. However, a majority of patients eventually develop resistance to these therapies and relapse into the lethal, castration-resistant form of PCa to which no adequate treatment option remains. Hence, there is an immediate need to develop effective therapeutic agents toward this patient population. Imidazopyridines have recently been shown to possess Akt kinase inhibitory activity; thus in this study, we investigated the inhibitory effect of novel imidazopyridine derivatives HIMP ...

Predicting Other Cause Mortality Risk For Older Men With Localized Prostate Cancer: A Dissertation, Daniel M. Frendl 2015 University of Massachusetts Medical School

Predicting Other Cause Mortality Risk For Older Men With Localized Prostate Cancer: A Dissertation, Daniel M. Frendl

GSBS Dissertations and Theses

Background: Overtreatment of localized prostate cancer (PCa) is a concern as many men die of other causes prior to experiencing a treatment benefit. This dissertation characterizes the need for assessing other cause mortality (OCM) risk in older men with PCa and informs efforts to identify patients most likely to benefit from definitive PCa treatment.

Methods: Using the linked Surveillance Epidemiology and End Results-Medicare Health Outcomes Survey database, 2,931 men (mean age=75) newly diagnosed with clinical stage T1a-T3a PCa from 1998-2009 were identified. Survival analysis methods were used to compare observed 10-year OCM by primary treatment type. Age and ...
