Aging Overview

External factors

External factors: Nitric oxide
Aging type: Accelerate
Aging characteristic:
Category: Chemical compounds
Phenotype: Aging
Experimental category: L
Tissue type: --
Cell name: HeLa,MRC-5
PMID: 27845209
Experiment: SA-β-gal activity assay//qRT-PCR //ELISA
Description: NO treated HeLa cells stained positive for SA-βgal activity, a hallmark of cellular senescence and the percentage of stained cells increased proportionally to the dose of SNP . The senescent state was further confirmed by recording the induction in the expression of p21, NF-κb and IL8 and reduction in the expression of proliferation cell nuclear antigen (PCNA)at RNA level. Additionally, the levels of IL8 and IL6 cytokines, a part of the senescence associated inflammatory phenotype were also significantly elevated after SNP or DETA.


Regulatory relationship

Target gene: ATM
R-EF-Target gene: Activation
Official symbol(s): ATM
Target gene experiment: Cell viability assay
Target gene description: Towards this, cells were treated with NO in the presence of a specific ATM kinase inhibitor, KU-55933 [46]. It is known that ATM kinase inhibition leads to an increase in ROS levels [44,45,47], which was observed when HeLa cells were treated with KU-55933, which increased further on NO treatment and was accompanied with significant loss of cell viability, as determined by a reduction in their proliferation as well as their metabolic activity .
