Figure 1

A, representative Caenorhabditis elegans MZE91R (unc-119(ed3) III; cbgIs91[pPept-1:pept-1::DsRed;unc-119(+)]; rrf-3(pk1426) II) expressing the PEPT1::DsRed fusion protein at the intestinal brush border membrane (red signal). B, PEPT1::DsRed expression in MZE91R C. elegans after RNA interference (RNAi) gene silencing of pept-1 and nhx-2. The RNAi feeding protocol described in Fraser et al. (2000a) was used. Controls were fed on bacteria carrying the empty pPD129.36 vector. Values are based on four independent experiments showing mean ± SEM. For statistical analysis, the Kruskal–Wallis test was performed with **P ≤ 0.01 and ***P ≤ 0.001.
