Scientists find hormone activity explains adolescent mood swings
... Smith and colleagues identified the site on human recombinant
alpha4-beta2-delta GABA-A receptors that produced the anxiety response, and were able to mutate the site to prevent the novel effect of the stress hormone. In contrast, neither the receptor nor the necessary conditions exist for this anxiety-producin...

Study uncovers mutation responsible for Noonan Syndrome
...on crystal structures of SOS1, the scientists made recombinant
versions of the mutants and expressed them in mammalian cells, where it was discovered that they promoted excessive activation of RAS and its downstream target, MAP kinase, the same pathway activated by PTPN11 mutations. "These results are the fir...
'Failed' experiment yields a biocontrol agent that doesn't trigger antibiotic resistance
...bacterium. The host bacterium then replicates the recombinant
plasmid and transfers copies of it to other bacteria in a process called conjugation. As he investigated the failed experiment, Filutowicz - who has spent two decades studying how plasmid replication is regulated - made a critical observation. A p...
