Omega-3 Fats May Help Turn On a Cancer-Suppressing Gene in Oral Cells
Researchers studied lab-grown oral cells that already showed early, pre-cancerous changes (called dysplastic keratinocytes). They exposed these cells to different fatty acids: arachidonic acid (an omega-6), and EPA and DHA (two omega-3s), to see how they affected cell behavior and gene activity.
The omega-3s, EPA and DHA, reduced the viability (survival/growth) of these abnormal cells at every dose tested. In contrast, the omega-6 fatty acid arachidonic acid increased the cells’ ability to migrate (spread) and shifted the cells’ omega-6 to omega-3 ratio higher.
While the DNA itself (TP53 gene and a related microRNA gene) wasn’t changed by the treatments, the omega-3s significantly increased the activity of microRNA-34a, a molecule known to act as a ‘tumor suppressor’ by helping regulate abnormal cell growth. This was not seen with the omega-6 fatty acid.
What this means for you
This is early-stage lab research using isolated oral cells, not a human clinical trial, so it doesn’t show that omega-3s treat or prevent oral cancer. However, it adds to a growing body of biological evidence suggesting omega-3 fats may support healthier cell regulation processes, consistent with other population-level research linking omega-3 intake to lower cancer risk.
