Abstract

Lymphoma is one of the most common malignant tumors in canine. Chemotherapy results in a high rate of remission; however, relapse and clinical drug resistance are usually seen within a year. Protein phosphatase 2A (PP2A) acts as a tumor suppressor and plays a critical role in mammalian cell transformation. Increased protein levels of SET, endogenous PP2A inhibitor, have been reported to correlate with poor prognosis in human leukemia. Here, we test the potential therapeutic role for a SET antagonist in canine lymphoma. We observed SET protein levels increased in multiple canine lymphoma cell lines compared with primary peripheral blood cells. A novel SET antagonist OP449 increased PP2A activity and effectively killed SET high-expressing canine lymphoma cells, but not SET low-expressing cells. Caspase-3 activation and enhanced Annexin V positive staining were observed after OP449 treatment, suggesting apoptotic cell death by OP449. Consistent with this, pan-caspase inhibitor Z-VAD-FMK blocked OP449 induced cell death. These data demonstrated the potential therapeutic application of SET antagonists for canine lymphoma.

Attention Score in Context

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 31 March 2013.
All research outputs
#22,759,802
of 25,374,917 outputs
Outputs from Journal of Veterinary Medical Science
#2,951
of 3,546 outputs
Outputs of similar age
#178,565
of 199,446 outputs
Outputs of similar age from Journal of Veterinary Medical Science
#15
of 25 outputs
Altmetric has tracked 25,374,917 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 3,546 research outputs from this source. They receive a mean Attention Score of 2.5. 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 199,446 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 25 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.
