Much of the information on the Cytochrome P450 enzymes (CYPs) is spread across literature and the internet. Aggregating knowledge about CYPs into one database makes the search more efficient. Text mining on 57 CYPs and drugs led to a mass of papers, which were screened manually for facts about metabolism, SNPs and their effects on drug degradation.(More)
In this issue, Comai et al. present evidence that previous support for Myf5-independent myogenic cell lineages was confounded by inefficiencies in lineage marking and ablation. Here, Haldar et al. discuss other possible explanations for the inconsistencies between different data sets and reiterate their views on Myf5-independent myogenesis.
Satellite cells (SCs) represent a distinct population of stem cells, essential for maintenance, growth and regeneration of adult skeletal muscle. SCs are mononuclear and are located between the basal lamina and the plasma membrane of myofibers. They are typically characterized by presence of the transcription factor paired-box 7 (PAX7) that is widely used(More)
The urodele amphibians (salamanders) are the only adult tetrapods able to regenerate the limb. It is unclear if this is an ancestral property that is retained in salamanders but lost in other tetrapods or if it evolved in salamanders. The three-finger protein Prod 1 is implicated in the mechanism of newt limb regeneration, and no orthologs have been found(More)
