| Abstract |
Previous study revealed that chromium malate improved the regulation of fasting blood glucose and insulin resistance in type 2 diabetic rats. In this study, the effect of chromium malate on anti-high-glucose and improve insulin resistance activities in L6 skeletal muscle cells with insulin resistance and its acting mechanism were investigated. Chromium malate showed direct anti-high-glucose activity in vitro. The glucose levels had a significant downward trend compared to chromium trichloride. Compared with model group, chromium malate could significantly promote the secretion levels of GLUT-4, Akt, Irs-1, PPARγ, PI3K and p38-MAPK, promote AMPKβ1 phosphorylation, and reduced the level of p-Irs-1 in L6 cells with insulin resistance. And the relate mRNA expression of chromium malate was significantly increased. Chromium malate is more effective at improving the related proteins and mRNA expression than those of chromium trichloride and chromium picolinate. Pretreatment with the specific p38MAPK inhibitor completely inhibited the GLUT-4 and Irs-1 proteins and mRNA expression induced by the chromium malate when compared with model group, but GLUT-4 and Irs-1 proteins and mRNA expression was partially inhibited after inhibiting p38MAPK/PI3K expression. The results suggested that chromium malate had a beneficial influence on the improvement of controlling glucose levels and insulin resistance in L6 cells with insulin resistance by regulating proteins production and genes expression in glucose uptake and insulin sensitivity signaling pathways. The signaling pathways of glucose uptake and insulin sensitivity. This study shown that chromium malate could significant increase in the production levels of GLUT-4, p-AMPKβ1, Akt, Irs-1, PPARγ, PI3K and p38-MAPK proteins and mRNA in L6 cells with insulin resistant. Pretreatment with the specific p38MAPK inhibitor completely inhibited the GLUT-4 and Irs-1 proteins and mRNA expression induced by the chromium malate compared to model group, but the proteins and mRNA were partially inhibited after inhibiting p38MAPK/PI3K. Therefore, chromium malate had beneficial influence on improvement of controlling glucose levels and insulin resistant in L6 cells by regulating proteins production and genes expression in glucose uptake and insulin sensitivity signaling pathways. The key proteins of glucose uptake and insulin sensitivity signaling pathways were p38MAPK, PI3K and PPARγ. |

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 17 February 2022.
All research outputs
#7,074,121
of 23,138,859 outputs
Outputs from BioMetals
#139
of 651 outputs
Outputs of similar age
#120,565
of 326,854 outputs
Outputs of similar age from BioMetals
#5
of 10 outputs
Altmetric has tracked 23,138,859 research outputs across all sources so far. This one has received more attention than most of these and is in the 68th percentile.
So far Altmetric has tracked 651 research outputs from this source. They receive a mean Attention Score of 4.4. This one has done well, scoring higher than 77% 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 326,854 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 62% 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 5 of them.
