Directly targeting microRNA-125b to block androgen receptor activity represents a novel approach for treating castrate-resistant prostate cancer. This promising new strategy for improving the effectiveness of anti-androgenic and other hormonal therapies is described in an article in BioResearch Open Access, a new bimonthly peer-reviewed open access journal from Mary Ann Liebert, Inc.. The article is available free online at the BioResearch Open Access website.
Prostate cancer is the most common non-skin cancer affecting men and the second most common cause of cancer death among men. In the article "miR-125b Regulation of Androgen Receptor Signaling Via Modulation of the Receptor Complex Co-Repressor NCOR2," Xiaoping Yang, Lynne Bernis, Lih-Jen Su, Dexiang Gao, and Thomas Flaig, University of Colorado Denver (Aurora) and University of Minnesota (Duluth), looked for targets of microRNA-125b that might shed light on its role in regulating prostate cancer and found that it directly inhibits NCOR2, which acts to repress the androgen receptor.
The authors point out that "the androgen receptor is a critical therapeutic target in prostate cancer" and that alterations in the receptor are essential for the development of castrate-resistant prostate cancer, in which the disease no longer responds to hormonal therapies.
"This research provides new insight into the mechanism of miR-125b regulation of castrate-resistance prostate cancer through the identification of a novel target for miR-125b," says Editor-in-Chief Jane Taylor, PhD, MRC Centre for Regenerative Medicine, University of Edinburgh, Scotland. "The clinical implications of this study are that targeted regulation of this miRNA may lead to more effective anticancer therapies."About the Journal

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
