Scientists reveal mechanisms behind oxygen toxicity

When it comes to oxygen, you can have too much of a good thing. Breathing air that contains higher levels of oxygen than the usual 21 percent found in Earth's atmosphere can cause organ damage, seizures, and even death in people and animals, particularly if it's in excess of the body's oxygen needs. Until now, however, scientists have mostly speculated about the mechanisms behind this phenomenon, known as oxygen toxicity, or hyperoxia.

Liver-produced hormone protects mice against the harmful effects of intoxication

A shot of a liver-produced hormone called FGF21 sobered up mice that had passed out from alcohol, allowing them to regain consciousness and coordination much faster than those that didn't receive this treatment, UT Southwestern researchers report in a new study.

Researchers provide an entirely new perspective on tissue oxygenation

Cardiovascular medicine, hematology and pulmonary medicine may soon have the first-ever therapies to correct poor tissue oxygenation, a key driver of disease in millions, including peripheral artery disease, sickle cell disease, heart failure, stroke, emphysema and many others.

Novel framework provides solutions to evade detoxification networks

Scientists at St. Jude Children's Research Hospital have demonstrated how drug makers can avoid two key problems: toxicity and resistance. The researchers made slight changes to a small molecule to reduce its metabolism and elimination by the cellular detoxification network regulated by the pregnane X receptor (PXR). This research provides a framework to develop solutions to the long-standing issue of how to evade detoxification networks using medicinal chemistry. The findings were published today in Proceedings of the National Academy of Sciences.

Accelerating the structure-guided discovery of chemogenetic tools

In order to more fully understand how diseases arise in the brain, scientists must unravel the intricate way neurons relay messages (either chemical or electrical) along a complex web of nerve cells. One way is by using a tool called DREADDs, which stands for Designer Receptors Activated by Designer Drugs.
