Fasnall Induces Atypically Transient Stress Granules Independently of FASN Inhibition

Abstract

Summary: Stress Granule formation has been linked to the resistance of some cancer cells to chemotherapeutic intervention. A number of studies have proposed that certain anti-tumor compounds promote cancer cell survival by inducing Stress Granule formation, leading to increased cellular fitness and apoptosis avoidance. Here we show that a potent fatty acid synthase inhibitor, fasnall, known for its anti-tumor capabilities, triggers the formation of atypical Stress Granules, independently of fatty acid synthase inhibition, characterized by high internal mobility and rapid turnover.
