| Abstract |
The resistance of tumor cells to apoptosis-inducing anticancer agents is regarded as a major impediment for the treatment of cancer patients. This study aimed to examine the possibility whether a necrosis-inducing peptide containing the mitochondria-targeting domain (MTD) of NOXA kills tumor cells that are resistant to apoptosis-inducing anticancer agents. To examine this possibility, we established doxorubicin-resistant (Dox-Res) cells by treating CT26 cells with increasing amounts of doxorubicin. The apoptosis resistance of the Dox-Res CT26 cells was confirmed by measuring the cell viability and activation of caspases. We showed that the MTD-containing peptide fused to eight arginine residues (R8:MTD), a necrosis-inducing peptide, induced necrosis in the Dox-Res CT26 cells, together with a cytosolic calcium spike, reactive oxygen species production, and the release of high mobility group box 1 into the media. Moreover, we demonstrated the killing effect of R8:MTD in tumor tissues generated using the Dox-Res CT26 cells in a mouse model. Therefore, our results suggest that MTD-containing peptides may provide an alternative tool for the elimination of relapsed tumor cells that are not responsive to apoptosis-inducing anticancer agents. |

Attention Score in Context
This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 10 September 2018.
All research outputs
#20,533,292
of 23,103,436 outputs
Outputs from Amino Acids
#1,291
of 1,529 outputs
Outputs of similar age
#292,783
of 336,306 outputs
Outputs of similar age from Amino Acids
#19
of 24 outputs
Altmetric has tracked 23,103,436 research outputs across all sources so far. This one is in the 1st percentile – i.e., 1% of other outputs scored the same or lower than it.
So far Altmetric has tracked 1,529 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 6.8. This one is in the 1st percentile – i.e., 1% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 336,306 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 24 others from the same source and published within six weeks on either side of this one. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
