Lipidomics in cancer research

Definition

Lipidomics in cancer research refers to the comprehensive study of lipids within biological systems, particularly in the context of cancer. This field aims to understand how lipid profiles change in cancerous tissues compared to normal tissues, revealing insights into tumor biology, metabolism, and potential therapeutic targets. By employing advanced analytical techniques, researchers can identify specific lipid species associated with cancer progression and treatment response, ultimately contributing to personalized medicine approaches.
