![CO attenuates mitochondrial dysfunction-derived sterile inflammation through TFEB-mediated mitophagy and mitochondrial biogenesis.Mice were exposed to LPS/D-galactosamine (D-GalN) with or without CO (250 ppm, 2 h/day) pretreatment, the blood and liver samples were collected 2 h and 6 h (b–i) after LPS/D-GalN administration. a The levels of ALT and AST were determined. Data are shown as mean ± SEM (n = 5). ***P < 0.001. b Liver sections were stained with H&E for morphological evaluation. c The levels of serum IL-1 beta were measured by ELISA.

Lamin B served as the nuclear standard. g Mitochondrial fractionation in liver tissues was analyzed by immunoblotting using antibodies against PINK1, Parkin, and LC3B-II. COX IV was used as marker for mitochondrial fractions. h, i The levels of autophagy-related genes and lysosomal genes (h) or mitochondrial biogenesis-associated genes (i) expressed in liver tissues were analyzed by qRT-PCR.

CO/CORM inhibits complexes of the mitochondrial respiratory chain (1) and then induces mitochondrial ROS (mtROS) production (2). Increased mtROS leads to PERK activation in the mitochondria-associated membrane (MAM) (3). The phosphorylation of PERK by mtROS increases intracellular calcium concentration. The activation of calcineurin by increased [Ca2 + ]i causes dephosphorylation of TREB (4), followed by its translocation into the nucleus. The nuclear translocation of TFEB increases the expression of genes involved in mitophagy (5) and mitochondrial biogenesis (6) Image collected and cropped by CiteAb from the following open publication (//pubmed.ncbi.nlm.nih.gov/30333475), licensed under a CC-BY license.

![RAP1 protects telomeres against DNA damageWestern blotting showing the expression of RAP1 and TRF2 in MRC-5 cells of different population doublings (PD). Senescent cells (PD 72) were left in culture for at least 4 weeks before harvesting for analysis.ChIP analysis of young (PD 30) and senescent (PD 72) MRC-5 cells performed with either anti-RAP1, anti-TRF2, or an IgG antibody. The immunoprecipitated and input products were loaded into a slot blot membrane and hybridized with a telomere probe, and stripped and hybridized to an Alu probe in order to determine unspecific binding. Quantification was performed by normalizing the telomere signal of the immunoprecipitated to that of the input. Data represent mean +/- SD of three biological replicates.Immunofluorescence detection of 53BP1 (red) and a FISH probe staining telomeres (green) in young (PD 26), pre-senescent (PD 66), and senescent (PD 72 + 4 weeks) MRC-5 fibroblasts. The upper graph shows the percentage of telomere co-localizing with 53BP1 (TIFs). Total DNA damage was measured by immunofluorescence detection of 53BP1. The lower graph shows the total number of 53BP1 foci per nucleus. Approximately 40-50 cells were analyzed per replicate and per condition. Bars represent SEM of two biological replicates.Data information: Statistical analyses were performed using Mann-Whitney U-test (*P 0.05, n = 18; group (mean % of cells with more than five 53BP1 ionizing radiation-induced foci +/−SE); unpaired t test].
