When misexpressed in late Drosophila prepupae, the transcription factor Fork head (Fkh) blocks death of the larval salivary glands that normally occurs in the early pupa. The aim of the experiment was to identify genes responding to Fkh that might mediate the effect of the protein on cell death and ...

The yeast transcription factor GAL4 has been reported to cause cell death and to have other biological effects when expressed in Drosophila (Kramer and Staveley, 2003: Genet. Mol. Res. 2, 43; Rezaval et al., 2007: Eur. J. Neurosci. 25, 683). Using heat-shock-induced expression of GAL4 to drive expre...

Cell-surface signaling is a sophisticated regulatory mechanism used by gram-negative bacteria to sense signals from outside the cell and transmit them into the cytoplasm. This regulatory system consists of an outer membrane-localized TonB-dependent receptor (TonB-dependent transducer), a cytoplasmic...
