Chloride ions evoke taste sensation by binding to sweet taste receptors

Humans perceive five basic taste sensations: sweet, umami, bitter, salty, and sour. Specific foods trigger taste recognition of these sensations through the activation of different receptors in our taste buds.

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.

New family of pharmaceutical compounds that target RNA

In Jennifer Hines’ lab, a group of graduate and undergraduate chemistry students recently discovered a new family of compounds that can target RNA and interfere with its function. In the future, RNA-targeted treatments to treat cancer and metabolic diseases, together with bacterial and viral infections, could be developed using the chemical scaffold found in this research.

Hemoglobin plays role as a chemosensory signal for mother mice to protect offspring

Biochemists in Japan were surprised to discover that the molecule hemoglobin in the blood works not only as an oxygen carrier, but when the blood is spilled as a result of aggression, accident or predator attack, the molecule also acts as a chemosensory signal -; a chemical stimulus picked up by the senses, namely smell in this case -; for lactating mother mice, prompting digging or rearing behavior in them to check the surrounding environment and keep their offspring safe.
