A delicate initiation: Lipolysis of lipid droplets fuels glioblastoma

Liu et al. (2021) demonstrate that CHKα2 is capable of promoting lipolysis of lipid droplets through mechanisms that require sequential steps of post-translational modifications after glucose deprivation. Intriguingly, the oxidation of fatty acids derived from lipid droplets is essential for the survival of tumor cells that informs clinical outcome among glioblastoma patients.
