Changes in jun N-terminal kinase activation by stress during aging of cultured normal human fibroblasts.

abstract：:We previously found that the small GTPase Rheb regulates the cell-cycle inhibitor p27KIP1 (p27) in colon cancer cells by a mTORC1-independent mechanism. However, the biological function of the Rheb/p27 axis in cancer cells remains unknown. Here, we show that siRNA-mediated depletion of Rheb decreases survival of human...
