Have you ever wondered how the same pathway can elicit different responses in distinct contexts? Check out the second part of my PhD work, now available @Dev_journal.Read the full story here: .Or read the tweetorial below (1/7).

Common modes of ERK induction resolve into context-specific signalling via emergent networks and cell-type-specific transcriptional repression. Read this #OpenAccess Research Article from @MartaPrera and @josh_brickman @reNEW_Global:.

Finally, although this paper only features @josh_brickman and myself, it could not have been possible without the amazing support of everyone at @Lab_Brickman ! (7/7) #Signalling #Transcription #FGF #ERK #Chromatin.

Finally, ERK represses pluripotent transcription in naïve cells and activates it in primed ones (even naïve pluripotency genes in primed cells) suggesting some sort of feedback mechanism accounts for the difference between naïve and primed pluripotent gene expression (6/7)

We also found that the chromatin accessibility landscape influences the transcriptional response: induction in naïve pluripotency involves chromatin remodelling, while in primed pluripotency it exploits existing accessible regions (5/7)

We used it to investigate what controls specificity of signalling responses in pluripotent cell types: naïve, rosette and primed. While we observed significant overlap in positive regulation at both chromatin and transcriptional level, repression was entirely cell specific (4/7)

Activation of ERK with this new model was more efficient in driving PrE from the ICM than the same length of FGF4 treatment (3/7)

We developed a new model that allows to induce ERK phosphorylation in vitro and in vivo, in your tissue and time of choice, a variation on @Lab_Brickman previous intrinsic model of ERK induction in ESCs ( (2/7)
