Aging Overview

External factors

External factors: Ultraviolet radiation
Aging type: Accelerate
Aging characteristic:
Category: Other
Phenotype: Aging
Experimental category: HL
Tissue type: --
Cell name: HDF
PMID: 30118525
Experiment: SA-β-gal activity assay
Description: When cells were exposed to UVA (7.5 J/cm2) or UVB (0.25 J/cm2) for 24 h, S HDFs showed an increased number of SA-β-gal positive cells as compared to control-treated cells, whereas NS HDFs showed negative staining for SA-β-gal activity.


Regulatory relationship

Regulatory pathway: TLR4-ERK
R-EF-Pathway: --
Official symbol(s): TLR4-MAPK1
Pathway experiment: Mitochondrial flux analysis
Pathway description: Furthermore, ERK or TLR4 inhibitor-treated senescent HDFs had strikingly decreased OCR than control-treated cells, suggesting that TLR4-ERK signaling pathways can lead to control of mitochondrial metabolic profilings in senescent HDFs.
