DRAW IT Draw the following apoptotic pathway, whichoperates in human immune cells. A death signal isreceived when a molecule called Fas binds its cell-surfacereceptor. The binding of many Fas molecules to receptorscauses receptor clustering. The intracellular regions of thereceptors, when together, bind proteins called adaptorproteins. These in turn bind to inactive molecules ofcaspase-8, which become activated and then activatecaspase-3. Once activated, caspase-3 initiates apoptosis.

Many studies have indicated that autophagy and apoptosis play an important role in the pathogenesis of spinal cord injury. In recent years, research on autophagy-related signal transduction pathways has demonstrated that the phosphatidylinositol-3-kinase (PI3K)/protein kinase B (Akt)/mammalian target of rapamycin (mTOR) signaling pathway is closely associated with the initiation of autophagy. However, the mechanism of the pathological relationship between this signaling pathway and apoptosis in spinal cord injury is unclear. In this study, we used an in vitro model of spinal cord injury to observe the mechanism of the PI3K/Akt/mTOR signaling pathway and the apoptosis of neurons via the mitochondrial pathway. Mitochondrial pathway apoptosis-related proteins were detected by western blot. Akt and mTOR phosphorylation levels peaked 4 h after mechanical damage and then decreased. Following administration of the PI3K-specific…arrow_forwardA scientist observes a mutation in the transmembrane region of EGFR that eliminates its ability to be stabilized by binding interactions during dimerization after ligand binding. Which hypothesis regarding the effect of this mutation on EGF signaling is most likely to be correct? EGF signaling cascades would be active for longer in the cell. EGF signaling cascades would be active for a shorter period of time in the cell. EGF signaling cascades would not occur. EGF signaling would be unaffected.arrow_forward
