• Mitochondria: multifaceted regulators of aging

    Fig. 1. Mitochondrial Communication Modes. (A) Mitochondria communicate to the nucleus and other cells (i.e., mitochondrial endocrine signaling) using various mediators such as ROS, UPRmt, DAMPs, and mitochondrialencoded MDPs. (B) Mitochondria also
    communicate with other organelles (e.g., endoplasmic reticulum, lysosomes, and peroxisomes) to coordinate complex cellular processes.
  • Cellular senescence: a promising strategy for cancer therapy

    Fig. 1. Molecular pathways of cellular senescence. DDR (DNA damage response) triggered by telomere erosion or OIS (oncogeneinduced senescence) is mediated by ATM/CHK2 and ATR/CHK1, which blocks cell cycle progression via phosphorylation and stabilization of p53. Activated p53 induces transcription of CDK inhibitor p21CIP1encoded by CDKN1A, which inhibits CDK2 activity, thereby activating RB and inducing cell cycle arrest. In parallel, various stressors also induce expression of the CDKN2A locus, which consists of p14ARF, p16INK4a, and p15INK4B. p14ARF prevents p53 destabilization by degrading the MDM2 protooncogene. Meanwhile, p16INK4a and p15INK4B suppress CDK4 and CDK6, thereby eventually activating RB. PICS (PTEN loss-induced cellular senescence) also activates p53 through the mTOR pathway. Altogether, prolonged activation of the p53/p21CIP1 and p16INK4a/RB signaling pathways leads to hypophosphorylation of RB, which blocks the cell cycle in G1 phase, and ultimately causes cellular senescence. RS and SIPS indicate replicative senescence and stress-induced premature senescence, respectively.
  • Cellular senescence in cancer

    Fig. 1. Schematic representation of the role of senescent cells in tumors. Senescent cells express SASP and are involved in interactions with the tissue microenvironment, including extracellular matrix (ECM) degradation, immune cells infiltration, and
    cancer invasion.
  • Senotherapeutics: emerging strategy for healthy aging and age-related disease

    Fig. 1. Senotherapeutics targeting SCs. CS induced by diverse factors is involved in many biological processes, embryonic development, tissue homeostasis, and tissue dysfunction, thus contributing to age-related pathologies and lifespan. Therefore, senotherapeutics targeting SCs is an emerging strategy of aging intervention for extension of health span and prevention and treatment of ARDs. Senotherapeutics is comprised of 3 classes: senolytics which kill SCs selectively; senomorphics which modulates or even reverses the phenotypes of SCs to those of young cells by interfering with triggers of CS, targeting SCs directly, or blocking SASP: and mediators of the immune-system clearance of SCs.
