| Abstract |
It is well accepted that β1 integrin plays a key role in maintaining normal podocytes form and functions; however, its mechanism of the potential protective effect remains unclear. Furthermore, the investigation and understanding of the non-lipid-dependent renal protection of Statins in addition to well-known lipid-lowering effect may provide the therapeutic utility and ultimately improve clinical outcome for patients with renal diseases. In the present study, we investigated the effect and mechanism of fluvastatin (FLV) on the expression of β1 integrin in puromycin aminonucleoside (PAN)-treated podocytes in vitro. Cultured human podocytes were treated with PAN, and/or different concentrations of FLV (1 × 10(-8)-1 × 10(-5 )mol/l), superoxide dismutase (SOD), or H2O2, respectively. The expression of β1 integrin and reactive oxygen species (ROS) in human podocytes under each experimental condition was evaluated by western blot, RT-PCR, and 2'7'-dichlorofluorescein 3'6'-diacetate, respectively. The viability of podocytes was also assessed by MTT colorimetry in the present study. The expression of β1 integrin was significantly decreased, and the synthesis of ROS was significantly increased in podocytes following either PAN or H2O2 treatment (p < 0.05). The up-regulation of β1 integrin and down-regulation of ROS were also observed in PAN-treated podocytes following lower concentrations of FLV or SOD treatment (p < 0.05, respectively). The cytotoxicity data derived from MTT assay revealed that lower podocyte viability was found in the presence of higher concentrations of FLV, PAN, or H2O2. Lower concentration of FLV or SOD can protect podocytes from being impaired by PAN treatment. FLV attenuated the podocyte injury induced by PAN and increased the production of β1 integrin in human podocytes in vitro. This underlying mechanism of FLV may be through inhibiting the activity of ROS in human podocytes. |

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 29 September 2014.
All research outputs
#20,237,640
of 22,764,165 outputs
Outputs from Molecular and Cellular Biochemistry
#1,796
of 2,297 outputs
Outputs of similar age
#209,851
of 251,167 outputs
Outputs of similar age from Molecular and Cellular Biochemistry
#17
of 40 outputs
Altmetric has tracked 22,764,165 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 2,297 research outputs from this source. They receive a mean Attention Score of 3.9. 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 251,167 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 40 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.
