Inhibition of the PI3K/AKT/mTOR pathway activates autophagy and compensatory Ras/Raf/MEK/ERK signalling in prostate cancer
... The PI3K/AKT/mTOR pathway is over-activated in many human cancers, including prostate cancer, and has emerged as a target for small molecule therapies [6–8]. However, inhibition of the PI3K pathway alone has proven to be ...

Sequential and combinatorial inputs from Nodal, Delta2/Notch and FGF/MEK/ERK signalling pathways establish a grid like organisation of distinct cell identities in the ascidian neural plate
... We have shown that Delta2/Notch signalling is required for column 4 fates. In order to address whether Delta2 is sufficient to promote column 4 fates, we overexpressed Ci-Delta2. This was carried out using an ...
