Transcriptome dataset of HEK293T cells depleted of one of the subunits of the DNA-PK complex: Ku70, Ku80 or DNA-PKcs

DNA-PK is a heterotrimeric complex that consists of Ku70 (XRCC6), Ku80 (XRCC5) and DNA-PKcs (PRKDC) subunits. The complex is a major player in the repair of DNA double strand break (DSB) via the non-homologous end joining (NHEJ) pathway. This process requires all DNA-PK subunits, since Ku70/Ku80 heterodimer firstly binds to DNA ends at DSB and then recruits DNA-PKcs. Recruitment of the DNA-PKcs subunit to DSB leads to phosphorylation events near DSB and recruitment of other NHEJ-related proteins that restore DNA integrity. However, today a lot of evidence demonstrates participation of the DNA-PK components in other cellular processes, e.g. telomere length maintenance, transcription, metabolism regulation, cytosolic DNA sensing, apoptosis, cellular movement and adhesion. It is important to note that not all the subunits of the DNA-PK complex are necessary for these processes, and the largest number of independent functions has been shown for the Ku70/Ku80 heterodimer and especially the Ku70 subunit. To better understand the role of each DNA-PK subunit in the cell life, we have analyzed transcriptome changes in HEK293T cells depleted of Ku70, Ku80 or DNA-PKcs using NGS-sequencing. Here, for the first time, we present the data obtained from the transcriptome analysis.
