Covalent inhibitor platform designed for targeting helicases in cancers and viral infections

by

Helicases are enzymes that unwind DNA and RNA. They’re central to cellular life, implicated in a number of cancers and infections—and, alas, extraordinarily difficult to target with drugs. Now, new research provides a powerful platform for designing covalent inhibitors tailored to target helicases. The paper, published in the Journal of the American Chemical Society, describes how researchers used … Read more

Cryo-EM structures elucidate parental histone transfer during DNA replication

by

A research team has recently made a significant breakthrough in understanding how the DNA copying machine helps pass on epigenetic information to maintain gene traits at each cell division.

Prolonged fasting triggers significant changes in bodywide protein levels, new study shows

by

New findings reveal that the body undergoes significant, systematic changes across multiple organs during prolonged periods of fasting. The results demonstrate evidence of health benefits beyond weight loss, but also show that any potentially health-altering changes appear to occur only after three days without food. The study, published in Nature Metabolism, advances our understanding of what’s happening across … Read more
