Thomas P. Mathews, PhD @mathews-tom.bsky.social · 02/09/2026You are what you eat! Omega-6 and omega-3 fatty acids are essential fatty acids, meaning we only get them from the foods we eat and our bodies need them to thrive.

Thomas P. Mathews, PhD @mathews-tom.bsky.social · 03/03/2026Great paper from Shana Kelley’s group about how the elongation of fatty acids by ELOVL6 maintains membrane anchor points that activate pathogenic KRAS variants. An unexpected way that fatty acid metabolism regulates a yet “unbridgeable” oncogenic variant. Very cool. www.nature.com/articles/s41...nature.comELOVL6 activity attenuation induces mutant KRAS degradation - Nature Chemical BiologyInhibition of ELOVL6, a fatty acid elongation enzyme, selectively degrades mutant KRAS, disrupts its membrane localization and suppresses tumor growth, revealing a novel vulnerability in KRAS-driven c... 020
