Figure 5(A) The effect of overexpression of the indicated TRs (Nanog, Irf6, Tfap4 and Irf6+Tfap4) on the expression of the other TRs of the network was determined by RT-qPCR analyses. Dark blue color denotes TRs upregulated more than 2 fold. Reduction by more than 2 fold in the expression is depicted by the absence of the corresponding TR. The light red and blue colored circles indicate downregulation or upregulation in the range of 1.3-2 fold, respectively, while grey circles indicate no change of gene expression. O: Oct4, S: Sox2, K: Klf4 and M: c-Myc. The light grey-green and red boxes depict the upstream and downstream layers of the 9TR GRN. The first panel on the left denotes the native 9TR GRN as shown in figure 4B (Phase III). (B) Shown is a bar graph depicting the effect of overexpression of the indicated TRs in reprogramming efficiency. Data are shown as mean ± SEM of at least two independent experiments. The y axis labeled as % reprogramming efficiency refers to the AP+ colonies scored as iPSCs. (C) Shown is a bar graph depicting the effects of rescue experiments in reprogramming efficiency. MEFs undergoing reprogramming were knocked down using shRNAs for the endogenous Nanog or Irf6 expression and were co-infected with a vector expressing an shRNA-resistant human homologue of Nanog or Irf6 (hNanog OE, hIrf6 OE). Data are shown as mean ± SEM of two independent experiments.
Figure 3(A) Ten-fold serial dilutions of the indicated strains were spotted on YPD containing the indicated concentrations of hydroxyurea (HU) and were incubated for 2-3 days. (B) mRNA synthesis rates (SR) as determined in Genomic Run-On analysis and (C) mRNA abundance (RA), in mog1∆ compared with wild type (WT) cells. Bar graphs showing the average level and standard deviation of three experiments (n=3) for SR and RA values obtained as the median of the whole gene dataset values in arbitrary units (x 107) from image analysis quantification. Error bars represent SD. Significance of the differences was obtained using Student´s t-test and statistical difference is considered as *, P value = 0.01-0.05; **, P value = 0.001-0.01; ***, P value < 0.001. The scatter plots (right panels) show the variation of the transcription (B) or mRNA (C) levels of individual genes. Pearson correlation values are: -0.039 (SR) and -0.042 (RA). This low correlation and the flat shape of the clouds on scatter plots (see red tendency line) indicates that there is no bias of the transcriptional effect with regard to expression level. (D) Box plots of SR and RA median levels of mog1Δ cells compared with WT for all genes (Total), SAGA and TFIID-dominated genes. These data were obtained from three independent replicates (n=3) of the RA and SR data that were averaged as explained in the main text. The median and standard deviation for the whole data set (Total) and for 351 (for RA) or 316 (SR) SAGA-dominated genes and for the 3903 (RA) or 3403 (SR) TFIID-dominated genes are shown. Significance of the differences was calculated using Student´s t-test. No significant difference between the different groups was found. The similar variations in SRs and RAs indicate that there are no changes in mRNA half-lives upon MOG1 deletion (shown in Fig EV4). The total number of genes with confident value in the analyses was 3953 for RA and 3989 for SR
