LABORATORY RESEARCH Development of Novel Radio-Chemotherapy Approaches Targeting Prostate Tumor Progenitor Cells Using Nanohybrids Investigators describe the synthesis of biocompatible, catechin-loaded and gelatin-conjugated carbon nanotubes with anticancer properties and demonstrate their potential for the eradication of prostate cancer stem cells in combination with X-ray irradiation. [Int J Cancer] Abstract Capsaicin Reduces the Metastatic Burden in the Transgenic Adenocarcinoma of the Mouse Prostate Model Scientists investigated the chemopreventive potential of capsaicin on prostate cancer using the transgenic adenocarcinoma of the mouse prostate (TRAMP) model. The TRAMP is a murine model that resembles the progression of human disease. [Prostate] Abstract Androgens Enhance the Glycolytic Metabolism and Lactate Export in Prostate Cancer Cells by Modulating the Expression of GLUT1, GLUT3, PFK, LDH and MCT4 Genes Researchers investigated the role of androgens in controlling the glycolytic metabolism and lactate efflux in prostate cancer cells. Androgen-responsive LNCaP cells were treated with 5α-dihydrotestosterone for 12-48 hours, and their glycolytic metabolism, lactate production and viability were analyzed. [J Cancer Res Clin Oncol] Abstract Gabarapl1 Mediates Androgen-Regulated Autophagy in Prostate Cancer Scientists found that GABA(Archive) receptor-associated protein like 1 (Gabarapl1), a ubiquitin-like modifier, participates in the regulation of autophagy. Gabarapl1 is transcriptionally regulated by androgen receptor and has a repressive role in autophagy. [Tumor Biol] Abstract The Stress Hormone Norepinephrine Increases Migration of Prostate Cancer Cells In Vitro and In Vivo Investigators examined norepinephrine’s possible role in metastasis formation and development in vitro and in vivo. Treatments with norepinephrine in mice xenografted with human DU145 prostate cancer cells increased the metastatic potential of these cells. [Int J Oncol] Abstract CLINICAL RESEARCH A Randomized, Double-Blind Study Comparing the Addition of Bicalutamide with or without Dutasteride to GnRH Analog Therapy in Men with Non-Metastatic Castrate-Resistant Prostate Cancer Researchers prospectively evaluated dutasteride plus bicalutamide in men with asymptomatic, non-metastatic castration-resistant prostate cancer with rising prostate-specific antigen. [Eur J Cancer] Abstract Categorical versus Continuous Circulating Tumor Cell Enumeration as Early Surrogate Marker for Therapy Response and Prognosis during Docetaxel Therapy in Metastatic Prostate Cancer Patients Investigators prospectively assessed categorical and continuous circulating tumor cell-counts for their utility in early prediction of radiographic response, progression-free and overall survival in metastatic castration-resistant prostate cancer patients treated with docetaxel. [BMC Cancer] Full Article Efficacy of Treatment with a GnRH Antagonist in Prostate Cancer Patients Previously Treated with a GnRH Agonist Researchers retrospectively examined 18 patients with prostate cancer who received androgen-deprivation therapy and who were treated with a GnRH antagonist (degarelix) after they showed an elevated PSA while on GnRH agonist therapy.
