Aging Overview

External factors

External factors: Homocysteine
Aging type: Accelerate
Aging characteristic:
Category: Chemical compounds
Phenotype: Aging
Experimental category: L
Tissue type: Aorta
Cell name: HUVEC
PMID: 25359865
Experiment: SA-β-gal activity assay//Western blot//qRT-PCR//Flow cytometry
Description: As expected, homocysteine could accelerate EC senescence when compared with standard conditions. Interestingly, homocysteine-increased p16, p21, and p53 expressions as well as SA-β-Gal positive cells, apoptosis cells, and cell cycle .


Regulatory relationship

Target gene: HTERT
R-EF-Target gene: Downregulation
Official symbol(s): HTERT
Target gene experiment: Western blot
Target gene description: Indeed, homocysteine also accelerated the reduction in hTERT mRNA and protein expression from P6 to P10. In addition, homocysteine decreased the expression of hTERT in a dose-dependent manner in P4-5 HUVECs.
