Abstract:
Biological systems do not exist in isolation. Analogous to the intricate design of a spider web, the metabolic adaptations propagated by glioblastoma cells are interlaced, creating a "defense mechanism" that increases the likelihood of mutagenesis and proliferation, while mitigating stress-induced tumor cell death and immune evasion. Previous studies have observed the role of cardiolipin (CL) in the electron transport chain (ETC) function and several other intracellular signaling pathways. Our review provides a synopsis of the existing knowledge about CL in glioblastoma and its complex relationship with metabolic reprogramming at the subcellular level. Through a meticulous examination of CL defects due to its biogenesis and stress-induced modifications, we seek to elucidate the multifaceted connections between aberrant CL variants and the metabolic alterations that underlie glioblastoma progression. A comprehensive grasp of these mechanisms could provide future direction in designing chemotherapeutic agents that selectively target glioblastoma, are less harmful to normal cells, and therefore, may extend patient survival.
