Purification and Properties of Rat Liver Tryptophan Oxygenase
Journal of Biological Chemistry, 1972 Abstract Tryptophan oxygenase has been purified from livers of glucocorticoid and l-tryptophan-treated rats. Homogeneity of the enzyme was established by polyacrylamide electrophoresis, sedimentation experiments, and immunodiffusion. Amino acid analyses reveal 6 residues of cysteine per enzyme molecule.

The microbiome in human skin aging
FEBS Letters, EarlyView.Age‐related skin changes encompass the well‐known visible phenotypic alterations, together with microbiome dysbiosis and a series of molecular aging hallmarks. These hallmarks characterize not only a fully stablished aged phenotype but also the skin aging process itself.

GCN2 in proteostasis: structural logic, signalling networks and disease
The FEBS Journal, EarlyView.Threats to protein synthesis activate the kinase GCN2, initiating the integrated stress response (ISR). GCN2 is triggered by stalled ribosomes and uncharged tRNAs, which accumulate when amino acids are scarce. The ISR adjusts cellular physiology by promoting redox balance, protein quality control, and mitochondrial optimisation.
