Project description:we report the mRNA expression of single cells at two different time points of HCC development upon inactivation of Rb family. The first time point corresponds to lesions appearing in the portal triad area 9 weeks after Rb family inactivation. The second time point corresponds to macroscopic tumors, typically visible at the 20-25 weeks time point.
Project description:we report the chromatin conformation profile of various liver progenitor subpopulations upon inactivation of the Rb family of proteins.
Project description:This serie was performed on liver progenitor isolated based on their expression of the Sca1 surface marker. It contains two independent samples from Rb family deficient liver and three independent samples from control liver, all isolated 2 weeks after Tamoxifen-induced Rb family ablation. Hematopoietic (CD45, Ter119) and endothelial (CD31) markers were used as negative selection markers to exclude blood or endothelial cells from the isolated fraction.
Project description:A mouse model of HCC has been developed based on the reported inactivation of the RB pathway in the majority of human HCC. This mouse model harbors floxed alleles of Rb and p130 genes, as well as germline mutation of the p107 gene. Various strategies to activate the activity of a Cre recombinase leads to the efficient deletion of the three genes in the liver of adult mice (TKO mice). Disruption of the RB pathway induces the rapid development of HCC. These HCCs share many similar features of human HCC.

Disruption of the RB pathway induces the rapid development of HCC. These HCCs share many similar features of human HCC. The goal of this array is to assess genome wide expression of TKO HCCs. Gene expression of control livers (n=4) or TKO HCCs (n=5) was measured using the Affymetrix GeneChip Mouse Genome 430-2.0 arrays
