Aging Overview

External factors

External factors: Melatonin
Aging type: Prevent
Aging characteristic:
Category: Chemical compounds
Phenotype: Systemic lupus erythematosus
Experimental category: L
Tissue type: Umbilical cord
Cell name: HUVEC
PMID: 32172204
Experiment: SA-β-gal activity assay//Western blot//BrdU assay
Description: Senescent cells were decreased in the melatonin-treated group.P53 and P21 were downregulated whereas Cyclin D1, CDK4, and CDK6 were upregulatedwhen cells were cultured with melatonin.Ten μM melatonin increased HUVEC proliferation in SLE medium.

Regulatory relationship

Target gene: RORα
R-EF-Target gene: Activation
Official symbol(s): RORA
Target gene experiment: Knockdown//SA-β-gal activity assay//Western blot//BrdU assay
Target gene description: RORα-knockdown increased the percentage of senescent HUVECs, although cells were treated with melatonin. P53 and P21 were increased whereas Cyclin D1, CDK4, and CDK6 were decreased when RORα was silenced in HUVECs, although cells were protected with melatonin.However, in the RORα-silenced group, HUVEC proliferation was inhibited, although cells were treated with melatonin.
