E-MTAB-9848
RNAseq of HCT116 p53KO cells transfected with either siRNA silencing ZNF84 or with negative control siRNA, in 2 variants of experiment a) with doxorubicin treatment (doxorubicin added 48h post-transfection, for the next 48h before harvesting) b) untreated, cultured 72h post-transfection
The aim of this experiments was to characterise the transcriptomic changes occurring in cancer cells, in which ZNF84 gene is silenced, in control conditions and when cells undergo stress by being treated with cytostatic doses of doxorubicin. We anticipated that ZNF84 regulates the level of p21 cell cycle inhibitor and therefore contributes to senescence induction in response to stress. We wanted to know whether attenuation of senescence in cells with downregulated ZNF84 is accompanied by alterations in other biological processes and signalling pathways. Cells were transfected with 30 nM siRNA (against ZNF84 or negative control siRNA) and then either a) doxorubicin was added (48 hours after transfection and cells were cultured in the presence of the drug for another 48 hours) b) no drug was added (cells were cultured in drug-free medium for 72 hours post- transfection)  Variants a) and b) were separate RNA sequencing experiments.
