± 3.3 <0.0001 77.8 ± 3.0 <0.0001 For qRT-PCR, samples were amplified with the actin oligo pair as a control, or with four pairs of Igl oligos: Igl 5', amplifying the 5' end of both Igl1 and Igl2, Igl 3', amplifying both Igl1 and Igl2 at the 3' end, and oligos specific for Igl1 and Igl2 individually, amplifying Igl1- or Igl2-specific sequences near the 5' end. Oligo sequences are shown in Table 3. Three biological replicates were each assayed in quadruplicate sets with each oligo pair, with the exception of the HM1:IMSS samples, which had one biological replicate. Igl and actin levels were calculated by using both the relative standard curve and the ΔΔC(t) method [54, 55] and actin was used as the normalization control. The average level of Igl PXD101 supplier in the GFP control shRNA transfectants was defined as 100% expression of Igl mRNA for computational purposes. Igl levels in the Igl transfectant samples and nontransfected HM1:IMSS were Sotrastaurin price compared to the GFP control, and are shown as the percentage of Igl mRNA relative to the GFP control (± SE). Statistical analysis was performed using Student’s

t test (two-tailed), groups were compared using ANOVA, and the GraphPad QuickCalcs P-value calculator [53] was used to calculate P-values. Knockdown of URE3-BP protein Two shRNA constructs were used to target URE3-BP: URE3-BP (350–378) and URE3-BP (580–608). Transfected trophozoites were selected with 100 μg/ml hygromycin (GFP control or URE3-BP (350–378) shRNA) or 75 μg/ml hygromycin (URE3-BP (580–608) shRNA) for 48 hours before harvesting. Actin

was used as a normalization and loading control. There was significant reduction of URE3-BP protein in both URE3-BP shRNA transfectants: for URE3-BP (350–378) Selleck Vorinostat it was 10.8 ± 1.0% and 13.8 ± 2.6% for URE3-BP (580–608) as compared to the GFP shRNA control (Figure 3, Table 6). HM1:IMSS samples were also included, but were not statistically different from the GFP shRNA control (Table 6).

The levels of URE3-BP and the actin standard were quantified from Western blotting. Values are expressed as the percentage of URE3-BP protein or mRNA of the GFP control shRNA transfectant level ± SE, with the P-value following each.
