The purpose of this study was to evaluate baseline RRM2 protein and gene expression in tumors of patients receiving 3-AP.
Tumor blocks from patients enrolled in phase I and II clinical studies using 3-AP, were evaluated for RRM2 gene and protein expression by quantitative real time polymerase chain reaction (Q-RTPCR) and automated quantitative analysis (AQUA).
Esophageal and gastric cancers overexpressed RRM2 protein when compared to prostate cancer (Z-score, 0.68 +/- 0.94 SD, vs 0.41 +/- 0.84 SD, respectively; p = 0.04). Esophageal and gastric cancers also overexpressed RRM2 mRNA when compared to prostate cancer (relative gene expression 2.56 +/- 1.49 SD, vs 0.29 +/- 0.20 SD, respectively; p = 0.02). Protein and gene expression were moderately associated (Spearman's rank correlation = 0.30; p = 0.12).
RRM2 gene and protein expression varies by tumor type.

Attention Score in Context
Attention Score in Context
This research output has an Altmetric Attention Score of 12. 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 21 June 2016.
All research outputs
#3,479,292
of 31,591,940 outputs
Outputs from Cancer Chemotherapy and Pharmacology
#106
of 3,150 outputs
Outputs of similar age
#11,089
of 131,635 outputs
Outputs of similar age from Cancer Chemotherapy and Pharmacology
#1
of 15 outputs
Altmetric has tracked 31,591,940 research outputs across all sources so far. Compared to these this one has done well and is in the 88th percentile: it's in the top 25% of all research outputs ever tracked by Altmetric.
So far Altmetric has tracked 3,150 research outputs from this source. They receive a mean Attention Score of 4.9. This one has done particularly well, scoring higher than 96% of its peers.
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 131,635 tracked outputs that were published within six weeks on either side of this one in any source. This one has done particularly well, scoring higher than 90% of its contemporaries.
We're also able to compare this research output to 15 others from the same source and published within six weeks on either side of this one. This one has done particularly well, scoring higher than 93% of its contemporaries.
