Aggregation of PolyQ35 (IMAGE) University of Konstanz Caption Aggregation of PolyQ35 protein in C. elegans is suppressed by NAC. The images show the head region of worms expressing a Huntington's disease related polyglutamine-expanded protein (PolyQ35). Overexpression of NAC in the worm (right image) prevents aggregation and toxicity of PolyQ35.
