Aging Overview

External factors

External factors: Glucocorticoid
Aging type: Accelerate
Aging characteristic:
Category: Chemical compounds
Phenotype: Aging
Experimental category: L
Tissue type: --
Cell name: MSC
PMID: 23963647
Experiment: ELISA//qRT-PCR//Knockdown
Description: The proliferation rates of MSCs 4 weeks after being treated to block endogenous GCs were significantly higher than controls .Treatment with RU486 or GR siRNA significantly up-regulated the expression of telomerase mRNA . The telomere lengths of MSCs treated with RU486 were significantly longer than those in controls . The MSCs treated with GR siRNA also had relatively longer telomeres than those in controls, but the differences are marginally significant (p=0.0625). In addition, total SOD activity, which is a key antioxidant, was 30–40% higher in MSCs that had been treated with RU486 or GR siRNA than in controls and these differences were statistically significant.
