Figure Lengend Snippet: CCG-1423-derived inhibitors act as general transcription inhibitors A. Effect of CCG-1423 and Actinomycin D (ActD) on baseline expression of Ecdysone responsive gene Eip74ef in S2R+ fly cells. Data is normalized to DMSO treated sample, from four biological replicates, bars represent the mean value, individual data points are shown and error bars are standard errors of the mean (s.e.m). Statistical significances are measured with student’s one-sample t-test (*; P< 0.025 with Bonferroni correction). P-values: DMSO vs ActD is 0.09 and DMSO vs CCG-1423 is 0.92. B. Effect of CCG-1423 and Actinomycin D (ActD) on transcriptional induction of Eip74ef upon 1 h of 20H-ecdysone stimulation. Data is fold changes in Eip74ef mRNA levels, from four biological replicates and shown as in A. Statistical significances are measured with one-way ANOVA followed by Tukey’s multiple comparison test (*; P< 0.025 with Bonferroni correction). P-values: DMSO vs ActD is 0.0006 and DMSO vs CCG-1423 is 0.021. C. Effect of CCG-derived compounds and ActD on nascent RNA production as measured by 5 ethynyl uridine (5-EU) incorporation in fly S2R+ cells. Top: Fluorescence microscopy images of representative cells, scale bar 30 microns. Bottom: Quantification of mean intensities of 5-EU staining in the indicated conditions from three biological replicates is shown as a 25th and 75th percentiles box plot, where the midpoint indicates the median value of EU intensities, the box represents mean and whiskers represent data range within 1.5IQR. Measurements from single cells shown as data points, with the total number of quantified cells indicated below the graph. Statistical significance with Mann-Whitney U-test (*; P< 0.017 with Bonferroni correction). P-values: DMSO vs ActD is < 0.0001, DMSO vs CCG-1423 is <0.0001, DMSO vs CCG-203971 is <0.0001. D. Effect of CCG-derived compounds and ActD on nascent RNA production as measured by 5 ethynyl uridine (5-EU) incorporation in mouse NIH 3T3 cells. Data is shown as in C. Statistical significance with Mann-Whitney U-test (*; P< 0.017 with Bonferroni correction). P-values: DMSO vs ActD is <0.0001, DMSO vs CCG-1423 is <0.0001, DMSO vs CCG-203971 is <0.0001.

Binding of RNA polymerase II to hsp genes in CCG-203971 treated mouse fibroblasts. Related to . A. Normalized (RPKM) coverage of RNA polymerase II phosphorylated on serine 5 (Pol2S5P) on heat shock responding gene Hsph1 in NIH 3T3 mouse cells in DMSO and CCG-203971 treated cells in non-heat shock (NHS) and heat shock (HS) conditions from ChIP-seq. B. Quantification of Pol2S5P on the gene body of the 15 hsp genes as normalized read counts (RPKM) in DMSO and CCG-203971 treated cells in non-heat shock (NHS) and heat shocked (HS) conditions in two replicate experiments. Data is shown as a 25th and 75th percentiles box plot, where the horizontal line represents the median, small box represents mean and whiskers represent data range within 1.5IQR. Statistical significance with Mann-Whitney U test (*; P< 0.05). C. Quantification of Pol2S5P around the transcription start site (TSS) of the hsp genes shown as in B. D. Quantification of Pol2S5P downstream of the CPS of the hsp genes shown as in B.
