Figure 5. Enhanced transcriptional elongation and generation of spliced mature transcripts after Lsh depletion.

Figure 5

(A) Schematic representation of the probe and primer pairs used to detect 5′ primary transcripts, unspliced transcripts and spliced mRNA. (B) Real time RT-PCR analysis detecting the ratio of unspliced to spliced mRNA of the HoxC6 and HoxC8 gene from Lsh+/+ and Lsh−/− MEFs. Results represent the mean and standard deviations of three independent experiments. (C) RT-PCR analysis for detection of HoxC6 and HoxC8 transcripts derived from nuclei of Lsh+/+ and Lsh−/− MEFs. U2 small nuclear RNA (snRNA) was unaffected by Lsh and served as a control. (D) Real-time RT-PCR analysis from four independent experiments to detect the ratio of unspliced to spliced nascent transcripts of HoxC6 and HoxC8 genes by nuclear run on assay. (E) Real time RT-PCR analyses detecting the ratio of unspliced to spliced mRNA of the HoxC6 and HoxC8 genes in Lsh−/− MEFs after Chd1 siRNA treatment. Error bars represent the standard deviations for the mean of three independent experiments.
