Experimental category: L
Tissue type: --
Cell name: WI-38
PMID: 32228197
Experiment: SA-β-gal activity assay//Western blot//RT-PCR
Description: Exposure of WI-38 cells to H2O2 for 4 days significantly increased the number of SA-b-Gal-positive cells compared to the control group. However, treatment with CORM-A1 markedly reversed the number of H2O2-induced SA-b-Gal-positive cells. CORM-A1 significantly reduced the expression of TNF-a IL-6, p21, and PAI-1 in H2O2- induced senescent cells.


Regulatory relationship

Target gene: MIR-34A
R-EF-Target gene: Downregulation
Official symbol(s): MIR-34A
Target gene experiment: RT-qPCR
Target gene description: CORM-A1 strongly decreased the expression of miR-34a.

Regulatory pathway: miR-34a-Sirt1
R-EF-Pathway: Downregulation
Pathway experiment: SA-β-gal activity assay//RT-PCR
Pathway description: CORM-A1 treatment significantly increased both mRNA and protein of Sirt1 levels.CORM-A1 strongly decreased the expression of miR-34a. CORM-A1 significantly decreased the number of miR-34a-overexpressing SA-b-Gal-positive cells. Notably, p21 and PAI-1 were upregulated by miR-34a overexpression, whereas CORM-A1 significantly reduced miR-34a-induced p21 and PAI-1 levels. Furthermore, the miR-34a-induced Sirt1 downregulation was reversed by CORM-A1.
