Interestingly, CPPMs of PC, PA, and PS but less so of PI and their corresponding lyso-GPL cleavage products suggested alterations in the Lands’ cycle of phospholipid remodeling in GB, i.e., enrichment of GPLs and concomitant depletion of lyso-GPLs in viable tumor (Fig. 5c). The gene discussed is IL31RA; the disease is neoplasm.
