    Inhibiting PDH, GLS1 and Hsp90 by the combination of CPI‐613+BPTES+17‐AAG gave rise to enhanced senolysis on senescent fibroblasts as well as the therapy‐induced senescent tumor cells. (A, B) The effects of CPI‐613+BPTES+17‐AAG combination treatment on proliferating (A) and senescent (B) BJ cells.

The activities of TCA cycle and chaperones are reduced in DNA damage induced senescent cells. Co‐inhibiting Hsp90 and TCA cycle with 17‐AAG+CPI‐613+BPTES combination leads to enhanced selective elimination of senescent cells, hinting TCA cycle and glutaminolysis are novel and potent targets for senolysis.

    Distinct proteomic and transcriptional signatures of metabolic enzymes and chaperones between senescent fibroblasts and the therapy‐induced senescent tumor cells. (A) The abundance of glycolysis‐related enzymes PFKP, ALDOA, PKM2, TCA cycle‐related PDHA, and glutaminolysis‐related GLS1 was decreased significantly in senescent BJ and IMR‐90 cells compared to their proliferating counterparts. (B) The protein levels of chaperones TCP1, Hsp70, and Hsp90 were decreased significantly in senescent BJ and IMR‐90 cells. (C) The abundance of those glycolysis‐related enzymes remained unchanged or even elevated in Dox‐induced senescent A549, HeLa, and U2OS tumor cells compared to their proliferating counterparts. (D) The abundance of these chaperone proteins in Dox‐induced senescent A549, HeLa, and U2OS tumor cells remained nearly unchanged. The relative abundance of each protein was quantified by signal density scanning on Western blots and normalized to the signal of β‐Actin or β‐tubulin. * p < 0.05, ** p < 0.01 tested by Student's t ‐test.
