CDK12 prevents MYC-induced transcription-replication conflicts [ChIP-seq] |
| Organism |
Homo sapiens |
| Experiment type |
Genome binding/occupancy profiling by high throughput sequencing
|
| Summary |
In order to identify genes and pathways necessary to preserve genome integrity upon Myc over-expression, we conducted a large siRNA-based screen in isogenic lines. We discovered several genes that suppressed the Myc-induced DNA-damage response and that were essential for the cell survival upon Myc activation. We idntified CDK12, a cyclin dependent kinase involved in transcriptional control and genome stability. We uncovered a novel and unexpected role of CDK12 in controlling transcription at loci proximal to DNA damaged sites and dissected its upstream regulatory pathways and downstream effectors. Mechanistic studies and genome-wide mapping of replication dynamics and DSBs revealed how CDK12 is essential to suppress intrinsic transcription-replication conflicts, thus avoiding cytotoxic DNA damage in cancer cells. Overall, this study uncovers a novel role for CDK12 and a new liability of Myc-driven cancers, which could be exploited for therapeutic purposes.

| Overall design |
U2OS cells were transfected with either non-targeting siRNAs (siLuc) or siRNAs targeting CDK12 (siCDK12). 48 hours post transfection cells were collected and processed for ChIP-seq analysis.
