    Alterations in cytokine secretion induced by gFA11. ( a ) Primary FRDA GM3816 fibroblasts were transfected in triplicate with gFA11 siRNA or Mut1 siRNA four times over twelve days. After the first transfection, the cells were grown in DMEM plus 5 mM BHB. At day 12, after the fourth transfection, cells were incubated with DMEM with BHB but without FBS. The following day, the medium was collected, concentrated, and analyzed by Luminex assay. Cytokine concentrations were normalized by cell numbers. ( b ) Primary FRDA GM3816 fibroblasts were infected with a gFA11-encoding vector or empty vector (E). Infected cells were selected with puromycin and expanded in glucose-based medium. Cells were then seeded at low density and kept in medium without FBS for 24 hours before collecting, concentrating, and analyzing the medium. *p < 0.05; **p < 0.01; ***p < 0.005 by Student’s t test. Error bars represent means ± 1 SD. The averages shown were calculated on three ( a ) or four ( b ) independent replicates and the results are representative of two independent experiments.

    Figure Lengend Snippet: p38 phosphorylation is not sustained by cytokines. Primary apparently healthy fibroblasts GM8399 were transfected with FXN siRNA or a random control clone. Two hours after transfection, cells were incubated with DMEM without FBS in presence of 500 nM BIRB796 or carrier control. The following day, ( a ) frataxin protein levels, ( b ) p38 phosphorylation levels, and ( c ) IL-6 levels were measured by ELISA. **p < 0.01; ***p < 0.005 by ANOVA with Tukey pair-wise comparisons. Error bars represent means ± 1 SD. In all experiments, the averages shown were calculated on three independent replicates and the results are representative of at least two independent experiments.

    Article Snippet: We obtained primary FRDA fibroblasts, GM3816 and GM3665B; age- and sex-matched apparently healthy control fibroblasts, GM8400 and GM8399; and FRDA lymphocytes, 15850, from Coriell (Coriell Institute for Medical Research, Camden, NJ).
