Phenotype: | Aging |
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 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. |
