Next generation sequencing facilitates quantitative analysis of control and TKO liver transcriptomes


ABSTRACT: We used RNAseq to analyse the transcriptomes of cycling and quiescent livers from cTKO (Rblox/lox;p130lox/lox;p107?/?) and control mice. mRNA profiles of cycling and quiescent control and TKO liver tissue were generated by deep sequencing in duplicate

In mammals, a cell's decision to divide is thought to be under the control of the Rb/E2F pathway. We previously found that inactivation of the Rb family of cell cycle inhibitors (Rb, p107, and p130) in quiescent liver progenitors leads to uncontrolled division and cancer initiation. Here, we show that, in contrast, deletion of the entire Rb gene family in mature hepatocytes is not sufficient for their long-term proliferation. The cell cycle block in Rb family mutant hepatocytes is independent of  ...[more]
