| Pattern | Transgenic animals (4-day-old young adult hermaphrodites) containing this OLD-1::GFP on extrachromosomal arrays or integrated arrays showed weak anterior expression, most likely in neuronal, hypodermal, and pharyngeal tissues. Expression was also observed in proximal regions of the male gonad, corresponding to regions of spermatid formation. An approximate 3-fold increase in GFP staining was observed during aging; note that the OLD-1::GFP construct extends the life span. Old worms showed GFP staining in most tissues, similar to the pattern observed in young worms, and weak gonadal staining. Thus, it appears that OLD-1 is upregulated over the life span. | |||
