Issue Image

Artist impression of the Csb/Xpa mouse model for the progeroid DNA repair disorder Cockayne syndrome. This animal model shows dwarf growth, neurological abnormalities, aging-associated pathology, and premature death. A comparison of the transcriptome of normal and mutant mouse livers revealed a novel link between genome instability and the age-related decline of the somatotroph axis (see van der Pluijm et al., e2).
