In my thesis, I focused on several underexplored areas of RNA splicing regulation. In the first part, I analyzed how chromatin and transcription regulatory elements change pre-mRNA splicing. In the second part, I studied why long non-coding RNAs (lncRNAs) are spliced less efficiently than protein-coding mRNAs. Finally, I was testing the importance of intron for the activating function of lncRNAs. It has been shown that chromatin and promoter identity modulate alternative splicing decisions. Here, I tested whether local chromatin and distant genomic elements that influence transcription can also modulate splicing. Using the chromatin modifying enzymes directly targeted to FOSL1 gene by TALE technology, I showed that changes in histone H3K9 methylation affect constitutive splicing. Furthermore, I provide evidence that deletion of transcription enhancer located several kilobases upstream of an alternative exons changes splicing pattern of the alternative exon. Many nascent lncRNAs undergo the same maturation steps as pre-mRNAs of protein- coding genes (PCGs), but they are often poorly spliced. To identify the underlying mechanisms for this phenomenon, we searched for putative splicing inhibitory sequences. Genome-wide analysis of intergenic lncRNAs (lincRNAs) revealed that, in general, they do not...

Pre-Detection converters avoid signal distortion created in later receiver stages, however should not add noise and distortion with their conversion process.
