Aging Overview

External factors

External factors: Gypenoside L
Aging type: Accelerate
Aging characteristic:
Category: Chemical compounds
Phenotype: Aging
Experimental category: L
Tissue type: --
Cell name: ECA-109,HepG2
PMID: 30889805
Experiment: SA-β-gal activity assay//qRT-PCR//EdU assay//Flow cytometry//Western blot
Description: Treatment with Gyp-L significantly increased the percentages of SA-β-gal-positive cells .The proportion of EdU-positive cells was higher in the control group, which was remarkably reduced in a concentration-dependent manner in the presence of Gyp-L, indicating that Gyp-L inhibited the proliferative activity of cancer cells.we detected the senescence-associated expression of SASP, such as IL-1α, IL-6, TIMP-1, CXCL-1 and CXCL-2, by qRT-PCR. As expected, the mRNA expression levels of all cytokines were increased by Gyp-L.Flow cytometry assay results demonstrated that a progressive increase of cells, retardant in S-phase, occurred in hepatic and esophagus cancer cells when treated with different concentrations of Gyp-L.Gyp-L significantly reduced the expression of all cell cycle regulators, such as CDK2, CDK4, CDK6, and cyclin D1, which was consistent with the arrested cell cycle.


Regulatory relationship

Regulatory pathway: MAPK//NF-κB//p38//ERK
R-EF-Pathway: Activation//Activation//Activation//Activation
Official symbol(s): MAPK//NFKB1//MAPK14//ERK
Pathway experiment: Western blot
Pathway description: We found that Gyp-L activated MAPK signals, mainly through p38 and ERK signaling pathways, in a dose-dependent manner in esophageal cancer.To explore its potential regulation in Gyp-L-induced senescence, a western blotting experiment was performed, which showed that the phosphorylation and activation of NF-κB was markedly up-regulated by Gyp-L in ECA-109 cells.Gyp-L also activated p38 and ERK in a dose-dependent manner in HepG2 cells.
