Fig. 3. Intestinal expression of rnh-1.3 is sufficient to extend lifespan. (A) RNH-1.3::GFP expression patterns. rnh-1.3 under its own promoter is expressed in the intestine andthe somatic gonad. Normarski (DIC, bottom panels) and fluorescence (GFP, top panels). (B) rnh-1.3 expression in the intestine under the act-5 promoter was sufficient to extend lifespan. (C) rnh-1.3 expression in the somatic gonad under the C25A8.4 promoter did not extend lifespan.
