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.

A novel synthetic antibody enables conditional “protein knockdown” in vertebrates

There are currently great hopes for solid-state batteries. They contain no liquid parts that could leak or catch fire. For this reason, they do not require cooling and are considered to be much safer, more reliable, and longer lasting than traditional lithium-ion batteries. Jülich scientists have now introduced a new concept that allows currents up to ten times greater during charging and discharging than previously described in the literature. The improvement was achieved by a “clever” choice of materials with a focus on consistently good compatibility. All components were made from phosphate compounds, which are well matched both chemically and mechanically.
The low current is considered one of the biggest hurdles in the development of solid-state batteries. It is the reason why the batteries take a relatively long...
