To improve transgene expression, either in the number of positive worms and/or an increased transgene signal per worm, we tested plasmid constructs incorporating 5_ and 3_ gene-specific genomic fragments, and parts of the open reading frame for two S. mansoni proteases, cathepsins F and D (SmCF and SmCD). GFP-expression was gut-localized, a novel finding for SmCD and consistent with previous data for SmCF. The mCherry fluorescent protein can also operate as a reporter. Though certain constructs imparted stronger and better distributed signals per positive worm, the low yields throughout precluded further quantifications of improvement. Electroporation of the same constructs was also weakly efficient. However, reporter signals were found in tissues other than the gut, which may represent dysregulated transcription.
