NAD+ kinase (NADK) is the only known cytosolic enzyme that converts NAD+ to NADP+, which is subsequently reduced to NADPH. The demand for NADPH in cancer cells is elevated as reducing equivalents are required for the high levels of nucleotide, protein and fatty acid synthesis found in proliferating cells, as well as for neutralizing high levels of reactive oxygen species (ROS). The aim of this study was to determine whether inhibition of NADK activity is a valid anti-cancer strategy alone and in combination with chemotherapeutic drugs known to induce ROS. In vitro and in vivo inhibition of NADK with either shRNA or thionicotinamide inhibited proliferation. Thionicotinamide enhanced ROS produced by several chemotherapeutic drugs and produced synergistic cell kill. NADK inhibitors alone or in combination with drugs that increase ROS-mediated stress may represent an efficacious antitumor combination and should be explored further.
This research output has an Altmetric Attention Score of 3. 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 25 February 2016.
All research outputs
#7,474,859
of 22,851,489 outputs
Outputs from Molecular Pharmacology
#1,096
of 3,279 outputs
Outputs of similar age
#88,905
of 263,447 outputs
Outputs of similar age from Molecular Pharmacology
#13
of 34 outputs
Altmetric has tracked 22,851,489 research outputs across all sources so far. This one is in the 44th percentile – i.e., 44% of other outputs scored the same or lower than it.
So far Altmetric has tracked 3,279 research outputs from this source. They receive a mean Attention Score of 4.7. This one is in the 25th percentile – i.e., 25% 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 263,447 tracked outputs that were published within six weeks on either side of this one in any source. This one has gotten more attention than average, scoring higher than 57% of its contemporaries.
We're also able to compare this research output to 34 others from the same source and published within six weeks on either side of this one. This one has gotten more attention than average, scoring higher than 50% of its contemporaries.
