| Experiment: | SA-β-gal activity assay//Cell morphological analysis//RT-PCR |
| Description: | Upon treatment with rapamycin,the percentage of AKT cells positive for SA-β-GAL was significantly reduced. Rapamycin treatment also dramatically reduced AKT-induced effects on cell size, and the SASP. |
| Regulatory pathway: | PI3K-Akt |

| Pathway experiment: | SA-β-gal activity assay//Cell morphological analysis//RT-PCR |
| Pathway description: | To determine the contribution of enhanced mTORC1 signalling to AKT-induced senescence, BJ-T cells transduced with myr-AKT or control pBABE were treated with the mTORC1-selective inhibitor, rapamycin and markers of senescence analysed. Upon treatment with rapamycin,the percentage of AKT cells positive for SAbGAL was significantly reduced . Rapamycin treatment also dramatically reduced AKT-induced effects on cell size , and the SASP ,indicating that mTORC1 activity is critical for PI3K/AKT-driven senescence. |
