BUFFALO, N.Y. — When cells experience enough chronic stress, they can stop dividing permanently. In this state of cellular limbo, known as replicative senescence, cells remain alive but no longer ...

A guardian molecule ensures that liver cells do not lose their identity. This has been discovered by researchers from the German Cancer Research Center (DKFZ), the Hector Institute für Translational ...

Coenzyme A, a molecule derived from vitamin B5, is vital for metabolism throughout the body. Scientists discovered that most of it resides inside mitochondria, yet how it reached these cellular ...

(Nanowerk News) By simulating the life cycle of a minimal bacterial cell — from DNA replication to protein translation to metabolism and cell division — scientists have opened a new frontier of ...

A team led by metabolism researcher Prof Timo D. Müller at Helmholtz Munich has developed a new approach for treating obesity and type 2 diabetes: a hybrid molecule uses the well-known GLP-1/GIP ...

Scientists have discovered that a rare “mirror-image” version of the amino acid cysteine can dramatically slow the growth of certain cancers while leaving healthy cells largely untouched. Unlike most ...

When cells experience enough chronic stress, they can stop dividing permanently. In this state of cellular limbo, known as replicative senescence, cells remain alive but no longer proliferate.
