Aging Overview

External factors

External factors: Palbociclib
Aging type: Accelerate
Aging characteristic:
Category: Chemical compounds
Phenotype: Gastric cancer
Experimental category: L
Tissue type: --
Cell name: AGS,MKN45
PMID: 28947133
Experiment: SA-β-gal activity assay
Description: Palbociclib-mediated antiproliferative effects were virtually identical in AGS and MKN-45 cells. SA-β-gal activity assay:the reduced proliferation in these cells was accompanied by an increase in the proportion of senescent cells, as assessed by senescence associated (SA)-β-galactosidase (SA-β- gal) staining.


Regulatory relationship

Target gene: CDK4/6//P53
R-EF-Target gene: Downregulation//Upregulation
Official symbol(s): CDK4/6//P53
Target gene experiment: Western blot//SA-β-gal activity assay
Target gene description: Western blot: Inhibition of CDK4/6 activity with suboptimal doses of Palbociclib (0.05 μM) together with the inhibition of autophagy using doses of 0.5 μM o f Spautin-1 (SP-1), resulted in a reduction in AGS cell proliferation that was greater than the inhibition induced by Palbociclib-only treatment .SA-β-gal activity assay:the proportion of giant, multinucleated senescent cells that were positive for SA-β-Gal activity was higher in cells treated with both drugs .Western blot:Through immunofluorescence and western blotting, an increase in total p53 levels in AGS cells treated with Palbociclib was evident,p53-deficient cells display a reduced ability to induce senescence following Palbociclib treatment.
