Figure Lengend Snippet: 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. For the dose of each compound in use, see the results 2.7 section for more details. ** p < 0.01 by Student's t ‐test. (C, D) The effects of CPI‐613+BPTES+17‐AAG combination treatment on proliferating and Dox‐induced senescent lung adenocarcinoma A549 cells. *** p < 0.001 by Student's t ‐test. (E, F) The effects of CPI‐613+BPTES+17‐AAG combination treatment on proliferating and Dox‐induced senescent cervical carcinoma HeLa cells. *** p < 0.001 by Student's t ‐test. (G) The morphological changes of senescent BJ induced by IR, senescent A549 and HeLa cells induced by Dox at the indicated time of CPI‐613+BPTES+17‐AAG treatment under the light microscopy. The senescent cells without treatment were stained with SA‐β‐gal. Cells were imaged at magnification 200×. (H) The schematic summarization of our findings. 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.

Figure Lengend Snippet: 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.
