TranscriptomicsTranscription profiling of mouse epidermis from Rb(F19/F19)K14cre;Rbl2-/- (pRb-;p130-) mutants to analyse functional redundancies between retinoblastoma family members
The epidermal-specific ablation of Rb gene leads to increased proliferation, aberrant differentiation, and the disengagement of these processes in vivo and in vitro. These differences in phenotype are more severe with the loss of p107, demonstrating the functional compensation between pRb and p107. ...

TranscriptomicsTranscription profiling of mouse stratified epithelial spontaneous SCC induced by the somatic inactivation of Rb1 and Trp53 tumor suppressors
The squamous cell carcinomas represent the aggressive type of non melanoma skin cancer, the most frequent malignancy among human population. We have studied here the possible relationship between these two pathways in skin using epidermal-specific mutant mice. Loss of p53, but not pRb, produces spon...

TranscriptomicsE2F1 loss induces spontaneous tumour development in Rb-deficient epidermis
The specific ablation of Rb1 gene in epidermis (RbF/F;K14cre) promotes proliferation and altered differentiation but does not produce spontaneous tumour development. These phenotypic changes are associated with increased expression of E2F members and E2F-dependent transcriptional activity. Here, we ...

TranscriptomicsA Novel Tumor suppressor network in squamous malignancies
The specific ablation of Rb1 gene in stratified epithelia (RbF/F;K14cre) promotes proliferation and altered differentiation but is insufficient to produce spontaneous tumors. The pRb relative, p107, compensates some of the functions of pRb in these tissues, however RbF/F;K14cre;p107-/- mice die post...

TranscriptomicsGene expression profiling of mouse p53-deficient epidermal carcinoma defines molecular determinants of human cancer malignancy (testing dataset)
The epidermal specific ablation of Trp53 gene leads to the spontaneous development of aggressive tumors in mice through a process that is accelerated by the simultaneous ablation of Rb gene. Since alterations of p53-dependent pathway are common hallmarks of aggressive, poor prognostic human cancers,...

TranscriptomicsGene expression profiling of mouse p53-deficient epidermal carcinoma defines molecular determinants of human cancer malignancy (training dataset)
The epidermal specific ablation of Trp53 gene leads to the spontaneous development of aggressive tumors in mice through a process that is accelerated by the simultaneous ablation of Rb gene. Since alterations of p53-dependent pathway are common hallmarks of aggressive, poor prognostic human cancers,...

TranscriptomicsTranscription profiling of mouse whole skin from pRB deficient animals reveals that p107 acts as a tumor suppressor
The specific deletion of Rb gene in epidermis leads to altered proliferation and differentiation, but not to the development of spontaneous tumors. Our previous data have demonstrated the existence of a functional compensation of Rb loss by Rbl1 (p107) in as the phenotypic differences with respect t...

TranscriptomicsIn vivo disruption of Rb-E2F-Ezh2 signaling loop causes bladder cancer development
Bladder cancer (BC) is a highly prevalent human disease in which Rb pathway inactivation and epigenetic alterations are common events. However, the connection between these two processes is still poorly understood. Here we show that the in vivo inactivation of all Rb family genes in the mouse urothe...
