Key acid-activated protein channel identified

Johns Hopkins researchers have discovered a long-sought protein, the proton-activated chloride channel (PAC), that is activated in acidic environments and could protect against the tissue-damaging effects of stroke, heart attack, cancer and inflammation. The researchers believe the discovery of this protein could provide a new drug target for potential therapies for stroke and other health issues.

Key drug target shown assembling in real-time

Over one-third of all FDA-approved drugs act on a specific family of proteins: G-protein coupled receptors (GPCRs). Drugs to treat high blood pressure, asthma, cancer, diabetes and myriad other conditions target GPCRs throughout the body—but a recent study shows what happens next. In results published in Cell, researchers outline the timeline of events, including precisely when and how different parts of a GPCR interacts with its G protein signaling partners. The findings provide new insights into the fundamental mechanisms of drug-induced signaling in cells, including ways to identify the most critical portions of GPCRs for targeting development of novel therapeutics.

Pyrrolizidine alkaloid levels in dried and deep-frozen spices and herbs too high

The German Federal Institute for Risk Assessment (BfR) deals regularly with the contamination of food with 1,2-unsaturated PA. It has already published opinions on the occurrence of 1,2-unsaturated PA in herbal teas, tea and honey, as well as a salad mixture contaminated with ragwort and food supplements (FS). The BfR has now made a health assessment of levels of 1,2-unsaturated PA determined by the monitoring authorities of the federal states in samples of various dried and deep-frozen herbs and spices.
