Melittin as a GPCR Lens for Translational GBM Research
2026-08-14
Glioblastoma research increasingly requires tools that connect lipid metabolism, GPCR signaling, tumor migration, and regulated cell death. This thought-leadership article positions Melittin as a bioactive peptide and signal transduction modulator for testing those connections, while distinguishing hypothesis generation from validated mechanism. It integrates findings from the miR-18a/ALOXE3 study with practical guidance on controls, sample handling, pathway readouts, and translational interpretation. The goal is not to present Melittin as a GBM therapy, but to show how a carefully controlled Gs/Gi perturbation strategy can sharpen mechanistic decisions in cancer biology research.
