Amyotrophic lateral sclerosis (ALS) is a lethal motor neuron disease with no cure. Currently there are only two ALS drugs approved by the FDA, both with a limited therapeutic effect. In the search for drug candidates for ALS, we studied the effect of known stem cell mobilizing agents (treatment) and antimetabolite 5-fluorouracil (5-FU) (anti-treatment) in SOD1G93A model of ALS. Surprisingly, we found that anti-cancer drug 5-FU increases lifespan, delays the disease onset and improves motor performance in ALS mice. Although we were not able to demonstrate the mechanistic basis of the beneficial 5-FU action in ALS mice, our findings suggest that 5-FU or similar drugs are possible drug candidates for the treatment of motor neuron diseases through drug repurposing. ; This work was funded by Instituto de Salud Carlos III and Fondo Europeo de Desarrollo Regional (FEDER) from the European Union (Grants PI14/00947 and PI17/00949), Asociación Adelante de La Roda, Plataforma Afectados por la ELA, Asociación Juntos Venceremos ELA, AVPA Zaragoza (RO), TERCEL (RD12/0019/0011 and RD16/0011/0035) and CIBERNED (CB06/05/1105) funds from the Instituto de Salud Carlos III of Spain (XN), and Fondazione Roma and Agenzia Spaziale Italiana (AM).
