Implication

Review demonstrates how sphingolipid signaling regulates DNA damage repair, chromatin state, and organelle homeostasis, highlighting therapeutic implications across cancer and neurodegeneration.

Key Points

To delineate the mechanistic connections linking canonical and atypical sphingolipid metabolism to DNA damage responses, chromatin dynamics, and organelle homeostasis in health and disease.
Synthesized molecular evidence detailing canonical and atypical sphingolipid metabolic pathways and their interactions with genotoxic stress response networks.
Evaluated stress-signaling cascades involving ceramide, nuclear sphingosine kinase 2, and organelle-specific disruptions across cancer, neurodegenerative disorders, and lysosomal storage diseases.
Ceramide signaling acts as a central checkpoint linking radiation, chemotherapy, and inflammation to kinase/phosphatase pathways and mitochondrial apoptosis.
Nuclear sphingosine kinase 2 generates sphingosine-1-phosphate to directly modulate histone deacetylase activity and chromatin-associated transcription.
Atypical sphingolipids, including 1-deoxysphingolipids, disrupt mitochondrial, endoplasmic reticulum, and lysosomal homeostasis, accelerating endogenous oxidative DNA damage.
