Study TitleInnate immune and metabolic signaling retain damaged mitochondria at cell membranes for mitoxyperilysis
Study SummaryInnate immune activation coupled with metabolic disruptions play critical roles in many diseases, often leading to mitochondrial dysfunction and oxidative stress that drive pathogenesis. However, mechanistic regulation under these conditions remains poorly defined. Here, we report a distinct lytic cell death mechanism induced by innate immune signaling and metabolic disruption, independent of caspase activity and previously described pyroptosis, PANoptosis, necroptosis, ferroptosis, and oxeiptosis. Instead, mitochondria undergoing BAX/BAK1/BID-dependent oxidative stress maintained prolonged plasma membrane contact, leading to local oxidative damage, a process we termed mitoxyperiosis. This process then caused membrane lysis and cell death, mitoxyperilysis. mTORC2 regulated the cell death, and mTOR inhibition restored cytoskeletal activity for lamellipodia retractions to mobilize mitochondria away from the membrane, preserving integrity. Activating this pathway in vivo regressed tumors in an mTORC2-dependent manner. Overall, our results identify a lytic cell death modality in response to the synergism of innate immune signaling and metabolic disruption.

Collection:

Collection ID:CO002838
Collection Summary:Ten million BMDMs were stimulated as indicated in 100 mm plates for 9 h. The medium was removed by aspiration, and the cells were washed once with ice-cold saline. Next, the cells were carefully harvested using a plastic scraper in 1.5 ml ice-cold saline. The cells were centrifuged at 150 × g for 2 min at room temperature, and the cell pellets were flash-frozen in liquid nitrogen and then stored at −80°C for a later extraction of metabolites.
Sample Type:Cultured cells
Storage Conditions:-80℃

Treatment:

Treatment ID:TR002854
Treatment Summary:Treatment of cells were done as indicated in the study design table. Four types of treatment were used in WT cells. "Media_WT", "LPS_WT", "CS_WT", "CS+LPS_WT" denote the WT cells receiving Media, LPS(lipopolysaccharide), CS(starvation) and CS+LPS treatment, respectively.

Sample Preparation:

Sampleprep ID:SP002851
Sampleprep Summary:Extraction of hydrophilic metabolites To extract the molecules with different polarity, an adapted three-phase solvent system was utilized to obtain total hydrophilic metabolites and lipids78. Briefly, the cell pellets were resuspended with 150 µL of saline, then 1.2 mL of chloroform/methanol/water (3:4:1, v/v/v) was added and homogenized using a Bead Ruptor Elite (OMNI international) for 30 s at 8 m/s. The homogenate was allowed to rest at 4ºC for 30 s and then centrifuged for 10 min at 21,000 g at 4ºC. After centrifugation, the upper aqueous phase was transferred into a new tube, frozen on dry ice, and then lyophilized. The dried extracts containing hydrophilic metabolites were dissolved using 40 µL of water: acetonitrile (95:5, v/v) supplemented with 10 mM ammonium acetate, then transferred into autosampler vials, and 4 µL per injection was analyzed by LC-MS.

Chromatography:

Chromatography ID:CH003336
Chromatography Summary:A Vanquish Horizon UHPLC (Thermo Fisher Scientific) was used for the LC separations, using stepped gradient conditions as follows: 0–16.5 min, 1 to 50% B; 16.5–18 min, 50 to 99% B; 18–36 min, 99% B; 36–39 min, 99 to 1% B; 39–45 min, 1% B.
