Apoptosis is a process of programmed cell death. Cisplatin, a chemotherapeutic drug, activates intrinsic pathway of apoptosis while TNF-alpha, a death ligand, activates the extrinsic pathway of apoptosis. Noncoding RNAs involve in regulation of apoptotic pathways at post-transcriptional level. Stable intronic sequence RNAs (sisRNAs) are the novel class of non-coding RNAs which can be generated by splicing- dependent and independent mechanisms. sisRNAs transcribed from their intronic promoter may contain 5’ cap and polyA tail. Despite the reports of several studies about sisRNAs in Xenopus and Drosophila, a genome-wide profile of sisRNAs in human is lacking. Therefore, we aimed to identify sisRNAs profile that are transcribed from their intronic promoter under cisplatin- and TNF-alpha- mediated apoptosis conditions. In this thesis study, the deep sequencing of total RNA, polyA + and polyA eliminated fractions from cisplatin-, TNFalpha-, DMSO-treated cells were performed. Differentially expressed intronic transcripts were analysed by DE-kupl algorithm. The intronic transcripts both in total RNA and polyA + RNA fractions but not in polyA eliminated fractions were screened visually on Integrated Genome Viewer (IGV) and selected as sisRNA candidateS. 48 sisRNA candidates were detected in cisplatin-treated data while 33 sisRNA candidates were detected in TNF-alpha- treated data. 5’ and 3’ RACE PCRs were performed for determination of transcriptional units of sisRNA candidates. Overexpression of sisRDOCK7-IT1 caused 8.09% increase in total apoptosis of HeLa cells in 48 hours. sisRDOCK7-IT1 triggers the activation of apoptosis but the mechanism of its induction of apoptosis is still unknown.
