The zebrafish has become a popular model organism to investigate many biological processes, in part owing to the combination of facile genetic manipulation and rapid, external embryonic development. The application of large-scale screening to identify chemical suppressors of a cancer-prone mutant highlights new technology for whole organism–based small-molecule discovery.
Development of small-molecule agonists against members of the tumor necrosis factor (TNF) receptor superfamily remains a considerable challenge. Presentation of ligand-derived peptides on a trimeric scaffold may point the way toward development of potent small-molecule agonists against this biologically important protein superfamily.
Sir2 is a key regulator in promoting longevity in response to a low-calorie diet. A new role for nitric oxide in promoting mitochondrial synthesis may be the reason why.
Identification of the monocarboxylate transporter 1 as a target of a new class of immunosuppressants shows that aerobic glycolysis and lactate release are essential for the proliferation of activated lymphocytes.
