(Submitter supplied) 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 spontaneous tumor development, indicating that, contrary to pRb, p53 is the predominant tumor suppressor acting in mouse epidermis. more...

(Submitter supplied) 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 to controls are intensified. However, the possible evolution of this aggravated phenotype, in particular in relationship with tumorigenesis, has not been evaluated due to the premature death of the double deficient mice. more...

Analysis of skin grafts lacking pRb, p107, or both genes. pRb and p107 belong to the retinoblastoma family important in cell cycle regulation. Results provide insight into the role of p107 in epidermal tumor development when pRb is absent.

(Submitter supplied) 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 have focused on the possible dependence on E2F1 gene function. We have generated mice that lack Rb1 in epidermis in an inducible manner (RbF/F;K14creERTM). more...

(Submitter supplied) Background and Aims: p53 can limit the self-renewal of stem cells from various tissues. Experimental evidence suggests that deletion of p53 can cooperate with other oncogenic events to induce aberrant self-renewal and transformation of progenitor cells. It is not known whether p53 deletion alone can lead to liver tumor formation. Methods: We used AlfpCre mice for liver-specific deletion of Trp53 in a conditional knockout mouse model to analyze liver carcinogenesis. more...

(Submitter supplied) Full title: Cancer Associated Fibroblasts are activated in incipient neoplasia to orchestrate tumor promoting inflammation in an NF-κB-dependent manner. Cancer Associated Fibroblasts (CAFs) support tumorigenesis by stimulating angiogenesis, cancer cell proliferation, and invasion. We demonstrate that CAFs also mediate tumor-enhancing inflammation. Using a mouse model of squamous skin cancer, we found a pro-inflammatory gene signature in CAFs isolated from dysplastic skin. more...

(Submitter supplied) 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. As p107 and p130 also exert overlapping functions in epidermis, we have generated Rb(F19/F19)K14cre;Rbl2-/- (pRb-;p130-) mice to analyze possible functional redundancies between pRb and p130. more...

(Submitter supplied) The p53 family comprises the tumor suppressor p53 and the structural homologs p63 and p73. How the three family members cooperate in tumor suppression remains unclear. Here, we report different but complementary functions of the individual members for regulating retinoblastoma protein (RB) function during myogenic differentiation. Whereas p53 transactivates the retinoblastoma gene, p63 and p73 induce the cyclin-dependent kinase inhibitor p57 to maintain RB in an active, hypophosphorylated state. more...

(Submitter supplied) 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 postnatally. Acute pRb loss in stratified epithelia, using an inducible mouse model (RbF/F;K14creERTM), shows that p107 exerts specific tumor suppressor functions in its absence. more...

(Submitter supplied) Despite its prevalence, the molecular basis of squamous cell carcinoma (SCC) remains poorly understood. We recently identified the developmental transcription factor Grhl3 as a potent tumor suppressor of SCC, and demonstrated that targeting of Grhl3 by a miR-21-dependent proto-oncogenic network underpins SCC in humans. Reduced levels of GRHL3 and its target gene PTEN are evident in human skin, and head and neck SCC, associated with increased expression of miR-21, which targets both tumor suppressors. more...

(Submitter supplied) Because TP53 mutation and CDH1 inactivation are the most common abnormalities found in human type II endometrial carcinomas, the contribution of dysfunctional TRP53 and CDH1 in the tumor microenvironment to induce type II endometrial cancer was characterized using mouse as a model. The results of our analysis revealed that conditional deletion of Cdh1 and Trp53 in the uterus regulated most of the genes categorized by their involvement in inflammatory responses, immune cell trafficking, cellular movement, cell-to-cell signaling and interaction and cellular growth and proliferation.

(Submitter supplied) 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, these mouse models can recapitulate the molecular features of some of these human malignancies. To evaluate this possibility, gene expression microarray analysis was performed in mouse samples. more...

(Submitter supplied) In many organs, adult stem cells are uniquely poised to serve as cancer cells of origin. In the epidermis, hair follicle stem cells (HFSCs) cycle through stages of quiescence (telogen) and proliferation (anagen) to drive hair growth. Within the hair follicle, HFSCs are capable of initiating squamous cell carcinoma, yet it is unclear how the hair cycle contributes to tumorigenesis. The data presented here show that HFSCs are unable to initiate tumors during the quiescent phase of the hair cycle, indicating that the mechanisms that keep HFSCs dormant are dominant to gain of oncogenes (Ras) or loss of tumor suppressors (p53). more...
