Figure 2. RNAi to the identified genes prevents growth control and morphological transformation.
a. In vivo growth of pleomorphic RNAi lines targeting distinct genes identified from the genome-wide screen for QS-signal resistance. RNAi was induced by provision of doxycyline to the infected animals (n=3, red lines), with parallel infections remaining uninduced (n=3, blue lines). Infections were terminated when the ascending parasitaemias were predicted to become lethal within 12 hours (crosses).
b.Morphology of PP1 RNAi cells and parental T. brucei AnTat1.1 90:13 cells (each grown in mice ±doxycycline) at 6 days post-infection. The induced PP1 cells remained predominently slender in morphology. Cells with slender (SL), intermediate (INT) or stumpy (ST) morphology are labelled. Bar=15μm.
