How Omega-3 Fats Disrupt Energy Production in Candida Biofilms

This laboratory study looked at how two omega-3 fatty acids, DHA and EPA, interfere with the formation of biofilms by Candida albicans, a fungus that can form drug-resistant colonies. Researchers used advanced gene and protein analysis techniques to see exactly which cellular pathways were affected when the fungus was exposed to these fatty acids at levels that stopped biofilm formation but didn’t kill the free-floating fungal cells.

Both DHA and EPA disrupted the fungus’s energy-producing machinery, particularly a process called oxidative phosphorylation that mitochondria use to generate energy. However, they got there through different routes: DHA broadly suppressed both gene activity and protein production related to energy metabolism and cell growth machinery, while EPA worked more selectively, affecting DNA replication genes directly and altering energy-related proteins mostly after the genes were already read.

The researchers concluded that despite these different mechanisms, both fatty acids converged on disrupting the fungus’s core energy metabolism, offering a possible explanation for why omega-3 fats show anti-biofilm activity in lab settings.
