Aging Overview

External factors

External factors: Glucose
Aging type: Accelerate
Aging characteristic:
Category: Chemical compounds
Phenotype: Aging
Experimental category: L
Tissue type: --
Cell name: WI-38
PMID: 23494737
Experiment: SA-β-gal activity assay//DAPI staining//Western blot//Cell morphological analysis
Description: We discovered that the percentages of SA-βgal positive cells were decreased significantly in the LG group compared with the NG and HG groups.Senescence induced by HG conditions was characterized by pronounced punctuated DNA foci, which were visualized by DAPI staining. Moreover, high glucose leads to cell hypertrophy and nuclear volume increase. The protein levels of p16INK4A (another biomarker of cell senescence) expression in the HG group were significantly higher than in the LG and NG groups.
