Retraction: TGFbeta1 activates c-Jun and Erk1 via alphaVbeta6 integrin.

The data published in this article [1] and in a preceding article in Molecular Cancer [2] were generated by myself, the corresponding author, with collaborators in Germany. The data were originally part of a manuscript on which my collaborators were authors and which remains unpublished. When publishing the data in Molecular Cancer, I failed to obtain the agreement from my past collaborators or to acknowledge their contributions, resulting in an unfair representation of their ideas and thoughts. In light of this, I have decided to retract the two papers. I deeply apologize for any inconvenience this may have caused.
