Aging Overview

Aging gene

Gene name: NDRG1
Aging type: Prevent
Aging characteristic:
Tissue type: --
Cell name: HepG2
Gene ID: 10397
Category: protein coding
Phenotype: Hepatocellular carcinoma
Experimental category: HL
PMID: 24302615
Experiment: SA-β-gal activity assay//Knockdown
Description: A large percentage (about 80%) of HepG2 cells transfected with NDRG1-specific siRNA was positive for SA-β-Gal staining.


Regulatory relationship

Regulatory pathway: GSK3β-P53/-P16
R-AG-Pathway: --
Official symbol(s): GSK3B-TP53-CDKN2A
Pathway experiment: SA-β-gal activity assay//Western blot
Pathway description: The percentage of SA-β-Gal positive cells was also reduced in HepG2 cells co-transfected with NDRG1-specific siRNA and siRNA against p53, p16, p53 & p16, or GSK-3. Western blot results indicated that co-transfection of NDRG1-specific siRNA and siRNA against p53, p16, or p53 & p16 increased p-Rb level which was decreased by NDRG1-specific siRNA . Additionally, GSK-3β siRNA decreased GSK-3β, GSK-3β 9ser, p53, p21 and p16 levels, indicating that GSK-3β can stabilize p53 and p16 levels in HepG2 cells with NDRG1 suppression. Consistently, a decrease in p21 (a p53 downstream target) and increased p-Rb were detected in cells co-treated with NDRG1-siRNA and PFT-α.
