| Abstract |
The present study was designed to investigate whether advanced glycation end products (AGEs) would regulate K(Ca)3.1 channels in cardiac fibroblasts and participate in cell proliferation. Cultured adult rat cardiac fibroblasts were employed to investigate the regulation of K(Ca)3.1 channels by advanced glycation end products-bovine serum albumin (AGE-BSA) and the role of K(Ca)3.1 channels in cell proliferation using approaches of molecular biology. K(Ca)3.1 channel mRNA and protein levels were greatly enhanced in cardiac fibroblasts treated with 200 μg/ml AGE-BSA, and the effects were countered by anti-RAGE antibody or the ERK1/2 inhibitor PD98059, the p38-MAPK inhibitor SB203580, and the PI3K/Akt inhibitor LY294002. In addition, AGE-BSA stimulated cell proliferation and collagen production in cultured cardiac fibroblasts, and the effects were reversed by K(Ca)3.1 blocker TRAM-34, anti-RAGE antibody, or signal inhibitors PD98059, SB203580, and LY294002. These results demonstrate for the first time that AGEs increase the expression of K(Ca)3.1 channels in a RAGE-dependent manner and promote cardiac fibroblast proliferation and collagen production, which is mediated by phosphorylation of ERK1/2, p38-MAPK, and PI3K/Akt signals. |

Attention Score in Context
This research output has an Altmetric Attention Score of 4. 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 08 January 2015.
All research outputs
#6,764,072
of 23,815,455 outputs
Outputs from Pflügers Archiv - European Journal of Physiology
#388
of 1,973 outputs
Outputs of similar age
#47,768
of 173,999 outputs
Outputs of similar age from Pflügers Archiv - European Journal of Physiology
#2
of 10 outputs
Altmetric has tracked 23,815,455 research outputs across all sources so far. This one has received more attention than most of these and is in the 70th percentile.
So far Altmetric has tracked 1,973 research outputs from this source. They receive a mean Attention Score of 5.0. This one has done well, scoring higher than 79% 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 173,999 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 71% of its contemporaries.
We're also able to compare this research output to 10 others from the same source and published within six weeks on either side of this one. This one has scored higher than 8 of them.
