The nuclear protein Sam68 plays a role in the genotoxic stress-initiated "nuclear to cytoplasmic" activation of NF-κB and is involved in the development and survival of colon cancer.
Polyglutamine expansion in mutant huntingtin disrupts a novel transcription-coupled DNA repair complex, providing an undescribed mechanism of neuronal toxicity and degeneration in Huntington's disease.

A large-scale RNA interference screen uncovers a new transcriptional regulatory program involving the histone H3 demethylase KDM3A, which mediates detachment-induced apoptosis (anoikis) in breast epithelial cells.
Mammalian cells were engineered to synthesize valine, a metabolic capacity that had been lost from the lineage of higher eukaryotes for >500 million years.
The endosymbiosis between an alga and the spotted salamander shows several parallels to invertebrate-algal symbioses as well as to pathogen associations in vertebrate animals.

An integrative approach, combining genetic mouse and large-scale human genetics studies, was used to reveal a novel role for the Bcl-2 protein Bid in maintenance of mitochondrial function that alters susceptibility to myocardial infarction.
