Senescence in pancreatic carcinogenesis: from signalling to chromatin remodelling and epigenetics.

Abstract excerpt

Mutational activation of K-Ras is a key genetic event involved in the initiation of pancreatic carcinogenesis. However, K-Ras generally fails to transform precursor lesions into invasive cancers due to activation of powerful fail-safe programmes that counteract transformation and growth. The importance of cellular senescence, a permanent cell growth arrest, is increasingly being recognised as a critical fail-safe...
