Targeting de novo lipogenesis as a novel approach in anti-cancer therapy

Area of Science:

• Oncology
• Cell Biology
• Biochemistry

Background:

• Altered cancer cell membrane physiology is recognized, but targeting membrane characteristics therapeutically remains underexplored.
• Current research lacks focus on exploiting membrane properties as a direct anti-cancer strategy.

Purpose of the Study:

• To investigate the functional impact of altered phospholipid composition on cancer cell membrane properties.
• To explore the potential of targeting membrane characteristics as a novel anti-cancer therapeutic strategy.

Main Methods:

• Inhibition of acetyl-CoA carboxylase 1 (ACC1) and fatty acid synthase (FASN) to alter phospholipid composition.
• Utilized advanced techniques including LC-MS/MS, optical tweezers, and fluorescence recovery after photobleaching.
• Assessed membrane characteristics and functional relevance through microscopy, molecular assays, and cancer progression experiments (migration, invasion, proliferation) in vitro and in vivo.

Main Results:

• Disturbing membrane deformability and lateral fluidity compromised dimerization, localization, and recycling of transmembrane receptors.
• Impaired growth factor receptor signaling cascades led to abrogated tumor growth and metastasis in various models.
• Demonstrated a direct link between membrane properties and cancer progression.

Conclusions:

• Membrane properties represent a promising druggable target for innovative anti-cancer agent development.
• This study establishes membrane characteristics as a viable strategy for future cancer therapies.
