| Description: |
Western blot: To further confirm the role of Sjp40 on cellular senescence, phosphorylation of Rb, which has been viewed as the crucial step in the progression of G1-S phase transition, was measured by Western blot. We observed obvious dephosphorylation of Rb in Sjp40-treated cells. |

| Pathway description: |
Western blot:Since Sjp40 treatment markedly increased the protein level of P27。SA-β-gal activity assay//Knockdown:SA-β-Gal positive percent mediated by Sjp40 in LX-2 cells obviously reduced via knockdown of P27, which confirmed the crucial role of P27 in regulating cellular aging induced by Sjp40。Western blot：SKP2 over-expression reversed P27 protein level induced by Sjp40, indicating that P27 expression induced by Sjp40 is dependent on SKP2 in LX-2 cells.SA-β-gal activity assay：Over-expression of SKP2 rescued the Sjp40-induced senescence analyzed by SA-β-Gal assay. |
