TOP STORY

Transcriptional Coactivators p300 and CBP Stimulate Estrogen Receptor-Beta Signaling and Regulate Cellular Events in Prostate Cancer
Steroid receptor coactivators p300 and CBP are highly expressed in advanced prostate cancer. They potentiate activation of androgen receptor by androgens and anti-androgens. In the present study, researchers addressed the question of whether these coactivators enhance activity of estrogen receptor-beta, which is variably expressed in prostate cancers. [Prostate]

SCIENCE NEWS

Molecule 968 Binds Glutaminase and Starves Cancer Cells, say Cornell Biologists
A molecule – simply called 968 – can starve cancer cells and the tumors they produce, says new research. [Press release from Cornell University discussing online prepublication in Cancer Cell]

Robot-Assisted Radical Prostatectomy Offers Effective 5-Year Cancer Control
Prostate cancer patients treated with robot-assisted radical prostatectomy can expect low rates of biochemical recurrence after 5 years, study findings showed. [Press release from MedWire News discussing online prepublication in European Urology]

CURRENT PUBLICATIONS (Ranked by Impact Factor of the Journal)

LABORATORY RESEARCH

Targeting Mitochondrial Glutaminase Activity Inhibits Oncogenic Transformation
Researchers described a small molecule inhibitor that blocks oncogenic transformation induced by various Rho GTPases in fibroblasts, and the growth of human breast cancer and B lymphoma cells, without affecting normal cells. [Cancer Cell]

A New Paradigm for Aptamer Therapeutic AS1411 Action: Uptake by Macropinocytosis and Its Stimulation by a Nucleolin-Dependent Mechanism
AS1411 is a first-in-class anticancer agent, currently in Phase II clinical trials. The data suggest a new model for AS1411 action, as well as a new role for nucleolin in stimulating macropinocytosis, a process with potential applications in drug delivery. [Cancer Res]

DLC1 Negatively Regulates Angiogenesis in a Paracrine Fashion
In this study, researchers silenced DLC1 in non-malignant prostate epithelial cells to explore its tumor suppression functions. [Cancer Res]

Chromatin Loading of E2F-MLL Complex by Cancer-Associated Coregulator ANCCA via Reading a Specific Histone Mark
The results suggest that ANCCA acts as a pioneer factor in E2F-dependent gene activation and that a novel mechanism involving ANCCA bromodomain may contribute to cancer cell proliferation. [Mol Cell Biol]

Research Resource: Estrogen-Driven Prolactin-Mediated Gene-Expression Networks in Hormone-Induced Prostatic Intraepithelial Neoplasia
In this study, researchers delineate the specific action(s) of E2 and prolactin in early prostate carcinogenesis by an integrated approach combining global transcription profiling, gene ontology, and gene-network mapping. [Mol Endocrinol]

Expression Pattern of Receptor Activator of NF(Kappa)B (RANK) in a Series of Primary Solid Tumors and Related Bone Metastases
Researchers retrospectively examined RANK ligand expression by immunohistochemistry in 74 bone metastases tissues from solid tumors, mostly breast, colorectal, renal, lung and prostate cancer. [J Cell Physiol ]

Changes in Cortical Cytoskeletal and Extracellular Matrix Gene Expression in Prostate Cancer are Related to Oncogenic ERG Deregulation
Specific changes in the cortical cytoskeleton were observed during prostate cancer progression. They parallel changes in the expression of extracellular matrix components and all together appear to be associated with oncogenic ERG overexpression. Researchers hypothesize that these alterations may contribute to the increased invasivity conferred to prostate cancer cells by ERG deregulation. [BMC Cancer]

CLINICAL RESEARCH

Castration-Dependent Pharmacokinetics of Docetaxel in Patients With Prostate Cancer
The objective of this study was to assess whether the low incidence of severe neutropenia in castrated men with prostate cancer treated with docetaxel was the result of changes in systemic clearance. [J Clin Oncol]

Biochemical Recurrence Following Robot-Assisted Radical Prostatectomy: Analysis of 1384 Patients with a Median 5-Year Follow-Up
In a contemporary cohort of patients with localized prostate cancer, robot-assisted radical prostatectomy confered effective 5-year biochemical control. [Eur Urol]

Single-Nucleotide Polymorphisms in p53 Pathway and Aggressiveness of Prostate Cancer in a Caucasian Population
In this study, researchers analyzed the association of single-nucleotide polymorphisms in p53, Mdm2, Mdm4 and Hausp genes with prostate cancer clinicopathologic variables in a large hospital-based Caucasian prostate cancer cohort (N = 4073). [ Clin Cancer Res]

A Phase II Study of Estramustine, Docetaxel, and Bevacizumab in Men with Castrate-Resistant Prostate Cancer
The combination of docetaxel, estramustine, and bevacizumab was tolerable but complicated by toxicity. Although the endpoint of progression-free survival did not meet the desired level, encouraging antitumor activity and overall survival were observed. [Cancer]
