Smac induces cytochrome c release and apoptosis independently from Bax/Bcl-xL in a strictly caspase-3-dependent manner in human carcinoma cells

2004

The mitochondrial apoptosis pathway mediates cell death through the release of various pro-apoptotic factors including cytochrome c and Smac, the second mitochondrial activator of caspases, into the cytosol. Smac was shown previously to inhibit IAP proteins and to facilitate initiation of the caspase cascade upon cytochrome c release. To investigate Smac function during apoptosis and to explore Smac as an experimental cancer therapeutic, we constructed an expression system based on a single adenoviral vector containing Smac under control of the Tet-off system supplied in cis. Conditional expression of Smac induced apoptosis in human HCT116 and DU145 carcinoma cells regardless of the loss of…

The hemoglobin genes of Drosophila

2006

We recently reported the unprecedented occurrence of a hemoglobin gene (glob1) in the fruitfly Drosophila melanogaster. Here we investigate the structure and evolution of the glob1 gene in other Drosophila species. We cloned and sequenced glob1 genes and cDNA from D. pseudoobscura and D. virilis, and identified the glob1 gene sequences of D. simulans, D. yakuba, D. erecta, D. ananassae, D. mojavensis and D. grimshawi in the databases. Gene structure (introns in helix positions D7.0 and G7.0), gene synteny and sequence of glob1 are highly conserved, with high ds/dn ratios indicating strong purifying selection. The data suggest an important role of the glob1 protein in Drosophila, which may b…
