Aging Overview

Aging gene

Gene name: EZH2
Aging type: Accelerate
Aging characteristic:
Tissue type: Human cartilage explants
Cell name: Chondrocytes
Gene ID: 2146
Category: protein coding
Phenotype: Osteoarthritis
Experimental category: L
PMID: 33177650
Experiment: ELISA//RT-PCR//Safranin-O
Description: We show that EPZ-6438 attenuated IL-1β-induced expression and release of MMP-1, -3 and -13 in chondrocytes, suggesting that this inhibitor could reduce chondrocyte catabolism. We confirmed this hypothesis using human cartilage explants. Safranin-O staining in explants treated with IL-1β for 48 h was less intense compared to untreated explants, showing that IL-1β induced a proteoglycan loss in cartilage. In the explants with the co-treatments of IL-1β with EPZ-6438, the safranin-O staining stayed intensively red, demonstrating that EPZ-6438 was able to preserve the proteoglycan content in the cartilage matrix, and consequently reduced cartilage degradation.


Regulatory relationship

Target gene: NGF
Official symbol(s): NGF
R-AG-Target gene: Upregulation
Subcategory: Unclear
Target gene experiment: RT-PCR
Target gene description: We showed that EZH2 overexpression increases IL-1β-mediated NGF expression. We showed that EZH2 overexpression increases IL-1β-mediated NGF expression, while EPZ-6438 had the opposite effect and reduced IL-1β-induced expression of NGF.
