Expression of zebrafish nkx2.5 in C. elegans body wall muscle activates expression of pharyngeal muscle-specific genes. (A and B) Adult animals bearing the unc-54∷nkx2.5 expression vector stained with the anti-MYO-2 antibody, 9.2.1. MYO-2 protein accumulates in pharyngeal muscles (ph) and body wall muscles (bw). Animals ectopically expressing either ceh-22 or nkx2.5 generally express MYO-2 in only a few (approximately 1–5) body wall muscle cells (15); the numbers of MYO-2 positive body wall muscles are similar in animals expressing either ceh-22 or nkx2.5. (C) An adult animal bearing the unc-54∷nkx2.5 transgene and expressing a B sub-element∷lacZ reporter in body wall muscles stained with X-Gal. β-Galactosidase staining accumulates in body wall muscle nuclei (marked by black bars).
