Identification of EP4 as a Potential Target for the Treatment of Castration-Resistant Prostate Cancer Using a Novel Xenograft Model
Findings reveal that EP4 overexpression, via androgen receptor activation, supports an important mechanism for castration-resistant progression of prostate cancer. [Cancer Res]

Using Nitroglycerin to Treat Prostate Cancer Shows Potential to Halt Disease
Treatment of prostate cancer using a very low dose of nitroglycerin may slow and even halt the progression of the disease without the severe side effects of current treatments. [Press release from ScienceDaily discussing online prepublication in Urology]

Lower Detection of Prostate Cancer with Prostate-Specific Antigen Screening in U.S. Than in a European Randomized Trial
Fewer prostate cancers were detected by prostate-specific antigen screening in the U.S. than in a European randomized trial because of lower screening sensitivity. [Press release from ScienceDaily discussing online prepublication in the Journal of the National Cancer Institute]

Loyola Study Points to Possible Novel Approach to Treating Breast Cancer, Prostate Cancer, Enlarged Hearts and Carney Complex
In a new approach to developing treatments for breast cancer, prostate cancer and enlarged hearts, researchers are zeroing in on a workhorse protein called RSK. [Press release from Loyola University Stritch School of Medicine discussing online prepublication in the Journal of Biological Chemistry]

LABORATORY RESEARCH

Long-Range Enhancers on 8q24 Regulate c-Myc
Here, researchers show that multiple enhancer elements are present within the region of chromosome 8q24 and that they can regulate transcription of Myc. In addition, the enhancer element physically interacts with the Myc promoter via transcription factor Tcf-4 binding and acts in an allele specific manner to regulate Myc expression. [Proc Natl Acad Sci U S A]

Oncolysis of Prostate Cancers Induced by Vesicular Stomatitis Virus in PTEN Knockout Mice
Results suggest that control of locally advanced human prostate cancer may be achievable through intraprostatic injection and amplification of a safe oncolytic virus, such as VSV(AV3). [Cancer Res]

Prosaposin Down-Modulation Decreases Metastatic Prostate Cancer Cell Adhesion, Migration, and Invasion
Findings suggest that by a coordinated regulation of ceramide levels, cathepsin D and beta1A-integrin expression, and attenuation of “inside-out” integrin-signaling pathway, prosaposin is involved in prostate cancer invasion and therefore might be used as a molecular target for prostate cancer therapy. [Mol Cancer]

Pim1 Kinase Synergizes with c-Myc to Induce Advanced Prostate Carcinoma
Results directly show functional cooperativity between c-Myc and PIM1 in prostate tumorigenesis in vivo and support efforts for targeting PIM1 in prostate cancer. [Oncogene] 

Low Levels of Phosphorylated Epidermal Growth Factor Receptor (pEGFR) in Nonmalignant and Malignant Prostate Tissue Predict Favorable Outcome in Prostate Cancer Patients
Low pEGFR immunoreactivity is associated with the favorable prognosis in prostate cancer patients and may provide information about which patients with Gleason score 6 and 7 tumors that will survive their disease even without treatment. Changes in the nonmalignant tissue adjacent to prostate tumors give prognostic information. [Clin Cancer Res]

The Histone Deacetylase Inhibitor Valproic Acid Inhibits Cancer Cell Proliferation via Down-Regulation of the Alzheimer Amyloid Precursor Protein
The data suggest that beta-amyloid precursor protein down-regulation via histone deacetylase inhibition provides a novel mechanism for pancreatic and colon cancer therapy. [J Biol Chem]

GAS6/AXL Axis Regulates Prostate Cancer Invasion, Proliferation, and Survival in the Bone Marrow Niche
Results suggest that the activation of GAS6 receptors on prostate cancer in the marrow environment may play a critical role as a molecular switch to establish dormancy. [Neoplasia]

Beta-TrCP Inhibition Reduces Prostate Cancer Cell Growth via Upregulation of the Aryl Hydrocarbon Receptor
Here researchers show that beta-TrCP depletion suppresses prostate cancer and identify a relevant growth control mechanism. shRNA targeted against beta-TrCP reduced prostate cancer cell growth and cooperated with androgen ablation in vitro and in vivo. [PLoS One]

CLINICAL RESEARCH

Prostate-Specific Antigen Screening in the United States versus in the European Randomized Study of Screening for Prostate Cancer-Rotterdam
Researchers conclude that the efficacy of prostate-specific antigen screening in detecting prostate cancer was lower in the United States than in the European Randomized Study of Screening for Prostate Cancer -Rotterdam. [J Natl Cancer Inst]
 
Phase I/II Study of Preoperative Docetaxel and Mitoxantrone for High-Risk Prostate Cancer
Preoperative chemotherapy with docetaxel and mitoxantrone is feasible. Approximately half of the high-risk patients remain free of disease recurrence at 5 years, and clinical and molecular predictors of early recurrence were identified. [Cancer]

Denosumab Demonstrated Superiority Over Zometa(R) in Pivotal Phase III Head-to-Head Trial in Prostate Cancer Patients With Bone Metastases
Amgen announced that a pivotal, Phase III, head-to-head trial evaluating denosumab versus Zometa(R) (zoledronic acid) in the treatment of bone metastases in 1,901 men with advanced prostate cancer met its primary and secondary endpoints. [Amgen Press Release]

Patient Access Network Opens 5 New Funds Including Prostate Cancer
Patient Access Network Foundation will expand its services to provide co-payment assistance for medications to underinsured patients through five new funds — including grants of up to $10,000 per year for prostate cancer patients. [PR Newswire]

Senate Rejects Stem Cell Legislation
By a vote of 21 to 12, the South Dakota Senate shot down a bill that could have repealed South Dakota’s ban on embryonic stem cell treatments. [South Dakota Senate, United States]

Parsing National Institutes of Health’s 2011 Budget: Is Big Science Up, Small Science Down?
Is National Institutes of Health Director Francis Collins planning to steer his ocean liner of an institute toward “big biology” at the expense of single-investigator grants? [National Institutes of Health, United States]

Medvedev Talks Science in Moscow
Russian science has been getting some bad press recently, what with a recent report on its declining productivity in scientific papers and a letter from expatriate scientists to the Russian president and prime minister warning of the parlous state of basic research.
