| Project Title: | Regulation of stress signalling by SCD1-derived phosphatidylinositols |
| Project Type: | Targeted lipidomics |
| Project Summary: | Cytotoxic stress activates stress-activated kinases, initiates adaptive mechanisms, including the unfolded protein response (UPR) and autophagy, and induces programmed cell death. Fatty acid unsaturation, controlled by stearoyl-CoA desaturase (SCD)1, prevents cytotoxic stress but the mechanisms are diffuse. We found that 1,2-dioleoyl-sn-glycero-3-phospho-(1’-myo-inositol) [PI(18:1/18:1)] is a SCD1-derived signaling lipid, which inhibits p38 mitogen-activated protein kinase (MAPK) activation, counteracts UPR, autophagy and apoptosis induction, and maintains cell morphology and proliferation. SCD1 expression and the cellular PI(18:1/18:1) proportion decrease during the onset of cell death, thereby activating stress signaling. This counter-regulation applies to mechanistically diverse death-inducing conditions and occurs in tissues of Scd1-defective mice. |
