Amplification of the cyclin E genes and overexpression of cyclin E proteins is very frequent in several human tumor types. In particular, overexpression of E cyclins was implicated in the pathogenesis of liver cancers. According to the current cell division models, E cyclins drive tumor cell proliferation by activating its kinase partner, the cyclin-dependent kinase 2 (CDK2). In this study, we demonstrate that E cyclins are dispensable for adult mouse physiology, but essential for liver cancer progression. Surprisingly, we found that the function of E cyclins in liver tumorigenesis is kinase independent. Our study suggests that agents targeting E cyclins would be efficacious in liver cancer treatment, as they would halt proliferation of tumor cells while sparing normal tissues.
