Figure Lengend Snippet: (A and B) Number of live HT-29 cells measured at 5 and 7 days post-transfection, respectively. The graphs represent the mean ± SEM of multiple independent experiments (n). (C) The graph illustrates how HT-29 cells grew over time and represents the mean ± SEM of the independent experiments (n) shown in A and B. (D and E) Number of live ZR-75-1 cells measured at 4 and 7 days post-transfection, respectively. The graphs represent the mean ± SEM of multiple independent experiments (n). (F) The graph illustrates how ZR-75-1 cells grew over time and represents the mean ± SEM of the multiple independent experiments (n) shown in D and E. The number of live cells was calculated as detailed in the material and methods using NucleoCounter NC-100. The percentage of reduction of the number of live cells was calculated by comparison between the mean of NT vs . the mean of the transfection with STAT6 siRNA sequences. STAT6 and non-targeting (NT) siRNA sequences were used at 100 nM as the final concentration. Non-transfected cells served as negative control and STAT6 siRNA sequences 1 and 4 and non-targeting siRNA are denoted as STAT6.1, STAT6.4 and NT, respectively.

Figure Lengend Snippet: STAT6 siRNA transfection was carried out at day 1 of cell culture with (A) STAT6.1 and (B) STAT6.4 at 100 nM. A second transfection was carried out in both cases with STAT6.1 and STAT6.4 at the same concentration 7 days after the first transfection. The graphs represent the number of live cells over time measured at day 7 and 14 days post-first transfection counted using NucleoCounter NC-100 as detailed in the material and methods section. The mean ± SEM of 3 independent experiments is represented in each graph. Control cells were non-transfected cells and STAT6 siRNA sequences 1 and 4 and non-targeting siRNA are denoted as STAT6.1, STAT6.4 and NT, respectively. The percentage of reduction of the number of live cells was calculated by comparison between the mean of NT vs . the mean of the individual transfection with STAT6 siRNA sequences, and sequential transfection with NT (NT+NT) vs . sequential transfection with STAT6.1 and STAT6.4.

Figure Lengend Snippet: Confirmation of microarray data by RT-PCR and protein expression. (A) RT-PCR analysis of selected gene transcription in resident macrophages uninfected or infected with S. pyogenes. Uninfected samples were loaded in lanes 1, and infected samples were loaded in lanes 2. β-Actin expression served as a control. (B) IL-6 protein expression by S. pyogenes-infected macrophages. Resident macrophages were isolated from the peritoneal cavity of mice after 1 h of infection with S. pyogenes and cultured in vitro for 2 h. Noninfected macrophages were used as a control. The levels of IL-6 in the supernatants were determined by ELISA. Each column represents the mean ± standard deviation of triplicate samples obtained from three independent experiments. P < 0.0001 (ANOVA).
