Dimitriadi M, Kye MJ, Kalloo G, Yersak JM, Sahin M, Hart AC. The Neuroprotective Drug Riluzole Acts via Small Conductance Ca2+-Activated K+ Channels to Ameliorate Defects in Spinal Muscular Atrophy Models. J Neurosci. 2013 Apr 10;33(15):6557-62. PubMed PMID: 23575853.
From the abstract: "... parallel genetic screens were undertaken in Drosophila and Caenorhabditis elegans SMA models to identify modifiers of the SMN loss of function phenotypes ... We examine here the impact of riluzole in two different SMA models. ... We propose that riluzole improves motor neuron function by acting on SK channels and suggest that SK channels may be important therapeutic targets for SMA patients."
