| Abstract |
Bone marrow mesenchymal stem cells (BMSCs) are potential therapy for diabetes. Owing to the oxidative stress caused by hyperglycemia, these transplanted BMSCs are with high rate of apoptotic death after transplantation. Ginkgo biloba L. extract (EGB) is a potent antioxidant which can remove free radicals. The study was to investigate whether EGB can protect BMSCs from oxidative stress in vitro and enhance the efficacy of BMSCs in lowering blood glucose levels after transplantation. BMSCs were cultured with H2O2, EGB, or H2O2 and EGB. Cell viability, malondialdehyde (MDA), superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), and cell death rates were determined. Diabetes was induced by single injection of streptozotocin (STZ) in male Wistar rats. Diabetic rats received EGB, BMSCs, or EGB/BMSCs. The serum levels of glucose, insulin, interleukin 6 (IL-6), tumor necrosis factor α (TNF-α), MDA, SOD, and GSH-Px were determined. PKCα expression and NF-κB activation in kidney were determined. The MDA levels and cell death rates in BMSCs cultured with H2O2 and EGB were significantly lower; cell viability, SOD, and GSH-Px activities were significantly higher compared with those with H2O2 alone. Compared with diabetic rats receiving BMSCs, diabetic rats receiving EGB before BMSCs transplantation showed (1) significantly lower levels of blood glucose, serum MDA, IL-6, and TNF-α, and higher levels of insulin, SOD, and GSH-Px activities; (2) significantly lower PKCα expression and NF-κB activation in the kidney. EGB administration before BMSC transplantation can enhance the effectiveness of BMSCs in lowering blood glucose levels and reversing oxidative stress in diabetic rats. |

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 23 July 2012.
All research outputs
#15,247,248
of 22,671,366 outputs
Outputs from Endocrine
#938
of 1,675 outputs
Outputs of similar age
#104,128
of 163,875 outputs
Outputs of similar age from Endocrine
#10
of 16 outputs
Altmetric has tracked 22,671,366 research outputs across all sources so far. This one is in the 22nd percentile – i.e., 22% of other outputs scored the same or lower than it.
So far Altmetric has tracked 1,675 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 5.1. This one is in the 34th percentile – i.e., 34% 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 163,875 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 26th percentile – i.e., 26% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 16 others from the same source and published within six weeks on either side of this one. This one is in the 31st percentile – i.e., 31% of its contemporaries scored the same or lower than it.
