| Title |
c-Jun impedes somatic cell reprogramming by activating mesenchymal core regulators and suppressing pluripotent ones |
| Organism |
Mus musculus |
| Experiment type |
Expression profiling by high throughput sequencing
Genome binding/occupancy profiling by high throughput sequencing
|
| Summary |
The somatic cell fate can be converted to tumor or pluripotent ones by ectopic expression of transcription factors in vitro and in vivo. Many oncogenic transcription factors are known to mediate both fates as they share similar proliferative and metabolic properties. Paradoxically, we found c-Jun as the first oncogene that appears to specify a somatic fate, oppose the pluripotent one and impede reprogramming. We performed a series of high through out sequencing to understand the way cJun works.

| Overall design |
To understand how c-Jun drives mESCs differentiating, we obtained c-Jun TetOn mESCs, and performed RNAseq 36h later with dox inducing or not . To understand why c-Jun blocks reprogramming while c-JunDN and Jdp2 can replace Oct4, we overexpressed these factors with KSM during reprogramming and performed RNAseq 3 Days after virus transfection. Moreover, to extend understand how these factors regulate gene expression, we also overexpressed these factors in MEF and performed RNAseq. Further more, to understand how cJun regulates cell fates and gene expression, we overexpressed c-Jun in mouse ESC and performed ChIP-seq. Also, we performed c-JunDN ChIP-seq during somatic cells reprogramming on day 3, to explore the binding sites of c-JunDN.
