High Bcr-Abl expression prevents the translocation of Bax and Bad to the mitochondrion.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Bcr-Abl is a constitutively active tyrosine kinase involved in the development and progression of chronic myeloid leukaemia (CML). It has been demonstrated that Bcr-Abl-positive cells can be uniquely resistant to apoptosis induced by different types of stimuli, but the mechanism by which this is achieved is not defined. In this study we have investigated how cells expressing high expression levels of Bcr-Abl may gain resistance to cytotoxic drugs. We have established cell lines expressing low and high expression levels of Bcr-Abl. Cells expressing elevated Bcr-Abl are resistant to cytotoxic drugs. In drug-sensitive 32D-parental and low Bcr-Abl expressing cells, pro-apoptotic Bcl-2 family members, Bax and Bad translocate from the cytosol to the mitochondrion following a cytotoxic insult. In contrast, high Bcr-Abl expression prevents the early translocation of these pro-apoptotic proteins to the mitochondrion, mitochondrial membrane potential is retained and caspases are inactive. We also demonstrate that IL-3 can contribute to drug resistance in low Bcr-Abl expressing cells, however, independent inhibition of IL-3 activated pathways (PI3K/AKT and Jak/STAT) does not sensitise cells to apoptosis. This study demonstrates that the subcellular translocation of Bax and Bad can be regulated by elevated Bcr-Abl expression and this may be a key event in the abrogation of an apoptotic response following a cytotoxic insult.
