Fig 2. The influence of (25S)-Δ7-DA on larval activation and development.
(A) Comparison of the ligand-binding domain (LBD) of DAF-12 of Haemonchus contortus (Hc-DAF-12) with that of Ac-DAF-12 from Ancylostoma caninum, using the following parameters: sequence length, root-mean-square deviation (RMSD), structural distance measure (SDM) and Q-score. (B) Activation of Hc-DAF-12 and Ac-DAF-12 by (25S)-Δ7-DA) in a luciferase reporter assay. The effects of 10 μM of (25S)-Δ7-DA on (C) larval exsheathment and (D) larval development. The effect of (25S)-Δ7-DA on larval development is both (E) dose- and (F) time- dependent. An error bar indicates a standard deviation (SD; four replicates). Statistical significance is indicated with one or more asterisks (*P < 0.05, **P < 0.01, ***P < 0.001, using Student’s t-test).
