Aging Overview

External factors

External factors: TCDD
Aging type: Accelerate
Aging characteristic:
Category: Chemical compounds
Phenotype: Aging
Experimental category: L
Tissue type: Brain
Cell name: Astrocyte
PMID: 25382668
Experiment: SA-β-gal activity assay//Flow cytometry //Western blot
Description: After treatment with different doses of TCDD for 96 h, and the rate of SA-β-Gal positive astrocytes was significantly elevated in a dose-dependent manner.Flow cytometry showed that there were more astrocytes restricted in the G1 phase harvested from the TCDD-treated group 74.64 ± 2.9%(P <0.01) than the control group 63.49 ± 3.3%, and cell populations in the S phase decreased in the TCDD-treated group 23.39 ± 3.29% (P <0.01) compared with the control group 15.63 ± 2.05%. The protein levels of p16 and p21 were evidently increased in astrocytes treated with different doses of TCDD for 96 h in a dose-dependent manner.


Regulatory relationship

Regulatory pathway: WNT-β-catenin
R-EF-Pathway: Upregulation
Official symbol(s): CTNNBIP1
Pathway experiment: Western blot
Pathway description: β-catenin was significantly up-regulated by TCDD in a dose-dependent manner, and peaked at 100 nm TCDD exposure.
