FRANCE; Postdoc – Genetics of Embryonic and Tumoral Development Biology
A post-doc position is now open in the Institut Curie, Paris France, in the Mechanics and Genetics of Embryonic and Tumoral Development biology/physics interdisciplinary team. We have recently discovered the mechano-sensitive expression of both Drosophila developmental genes and mammalian colon tumor progression genes[1-4]. Specifically, Armadillo/β-catenin is activated in response to mechanical strain and translocates into the nuclei in early Drosophila embryos and in APC/ colon tissues, where it transcribes developmental and tumour genes, such as Twist. These primary observations indicate a potential role of mechanical strains in colon cancer initiation or progression within the APC/ genetic context.
The project aims at testing the involvement of endogenous mechanical strains in tumour initiation or progression in the APC+/- genetic background, and at discovering the mechano-sensors initiating β-catenin activation for potential drug targeting.
