The mechanisms of transgene silencing in C. elegans are poorly understood, despite the importance of the nematode as a model for genetic research. Insertion of a transgene led to the expression of GFP in both the body wall and pharyngeal muscle cells of C. elegans as expected. However, subsequent generations stopped expressing body wall GFP. To reverse silencing, we have flanked the enhancers responsible for GFP expression with 601 sequences. The 601 sequence strongly positions nucleosomes. We hypothesize that this positioning will eliminate transgenerational gene silencing of body wall GFP.
