This atomic-level model of part of the human androgen receptor shows the target for a potential drug against prostate cancer. New research has determined the three-dimensional, atom-by atom structure of the target. The drug would bind to the receptor, interrupting its activity which drives the disease.
Scientists have determined the precise molecular structure of a potential new target for treating prostate cancer, a disease driven in part by abnormal testosterone activity. The target is part of the androgen receptor, a protein essential for testosterone to function in human cells. Prostate cancer is the most common cancer among men.
The androgen receptor and testosterone – technically, 5-alpha dihydrotestosterone – each drive prostate cancer at different stages of the disease. A common prostate cancer treatment uses drugs that compete with testosterone, blocking its ability to bind with the androgen receptor and so reducing the hormone’s effect. But cancer tends to become resistant to these drugs. The new research provides a novel strategy to block activation of both the androgen receptor and testosterone.
UCSF scientists determined the atom-by-atom topography of the pocket where proteins known as coactivators bind to the human androgen receptor to enable testosterone to trigger gene activity. Knowing the detailed shape greatly boosts the likelihood of developing a drug to block this binding and turn off androgen receptor activity, the scientists report.

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
