Description
Diamond-Blackfan anemia (DBA) is characterized by anemia and cancer susceptibility, and is caused by mutations in ribosomal genes, including Rpl11. Here, we report that Rpl11-heterozygous embryos are not viable, and homozygous deletion of Rpl11 in adult mice results in death within a few weeks, accompanied by bone marrow aplasia and intestinal atrophy. Importantly, deletion of a single Rpl11 allele in adult mice results in anemia associated to decreased erythroid progenitors and defective erythroid maturation. These phenotypes are also present in mice transplanted with inducible heterozygous Rpl11 bone marrow, indicating a cell-autonomous role of RPL11 in erythropoiesis. Additionally, fibroblasts lacking one or both Rpl11 alleles show defective p53 activation upon ribosomal stress or DNA damage. Furthermore, fibroblasts and hematopoietic tissues from heterozygous Rpl11 mice present higher basal cMYC levels. Accordingly, heterozygous Rpl11 mice are highly susceptible to radiation-induced lymphomagenesis. We conclude that Rpl11-deficient mice recapitulate DBA disorder, including cancer predisposition. Overall design: RNAseq profiles of bone marrow hematopoietic progenitors cells from WT (Rpl11+/+:: Tg.UbC-CreERT2) and LOX (Rpl11+/lox::Tb.Ub-CreERT2) mice, n=4 independent animals per genotype

Description
NANOG is a key pluripotency factor in embryonic stem cells that is frequently expressed in squamous cell carcinomas (SCCs). However, a direct link between NANOG and SCCs remains to be established. Here, we show that inducible overexpression of NANOG in mouse skin epithelia dramatically promotes the formation of carcinomas upon chemical carcinogenesis. Gene expression analyses in pre-malignant skin indicate that NANOG induces a large set of genes associated to stemness and to epithelial-mesenchymal transition (EMT). Overall design: 4 papillomas from different control mice (CTR), and 3 papillomas from different transgenic Nanog overexpressing mice (TG)

Description
We profiled total mRNA of pancreas and kidney tissues of 3 different strains (p53-null; In4a/Arf-null and WT) of reprogrammable mouse lines (they all express OCT4, SOX2, KLF4, C-MYC under the control of a tetracycline promoter, activated by doxycycline) Overall design: 5 mice of each genotype were treated with doxycycline to induce the expression of the reprogramming factors, they were sacrificed and total mRNA was extracted from pancreas and kidney tissues (we mapped >24M reads per sample)

Description
We aimed to analyze the transcriptional profile of lung epithelial cells early after the expression of a resident K-RasG12V oncogene. This approach was based on the rationale that valuable therapeutic targets should be easier to detect in the first stages of tumor development due to tumor heterogeneity which occurr at late stages.

Gene expression changes in 3 human melanoma cell lines were compared to freshly isolated normal primary melanocytes Overall design: Three biological replicates for each melanoma cell line and primary melanocytes were labeled and run Illumina HiSeq2500. The transcriptome of melanocytes was compared to cell line SK-Mel-28, SK-Mel-147 or UACC-62.

Description
Purpose: Asess the transcritpional changes induced upon RAB7 knock-down in melanoma (SK-Mel-28 and UACC-62) and in colon cancer (HCT-116) cell lines. Methods: mRNA profiles of tumor cell lines (SK-Mel-28, UACC-62, HCT-116) stably expressing scrambled shRNA or RAB7 shRNA (harvested at day 3 after lentiviral infection) were generated by deep sequencing, using three biological replicates per condition. The sequence reads that passed quality filters were analyzed with TopHat and Cufflinks. Validation of induced / silenced genes was performed by western blot. Results show a differential impact of RAB7 expression in the transcriptomic profile of melanoma vs non-melanoma cell lines, and support a lineage-specific role of this small GTPase in melanoma. Overall design: Examination of the mRNA profiles RAB7-depleted vs wild type cells, performed in parallel in 3 different tumor cell lines (Melanomas: SK-Mel-28 and UACC-62, Non-melanoma: HCT-116) harvested at day 3 after lentiviral infection.

Description
Obesity is a chronic, complex and multifactorial disease that has reached pandemia levels and is becoming a serious health problem. Intestinal microbiota is considered a main factor that affects body weight and fat mass, which points toward a critical role in the development of obesity. In this sense, probiotic bacteria might modulate the intestinal microbiota and the mucosal-associated lymphoid tissue. The aim of this study was to investigate the effects of L. paracasei, L. rhamnosus and B. breve feeding on the intestinal mucosa gene expression in a genetic animal model of obesity.
Publication Title
Adamdec1, Ednrb and Ptgs1/Cox1, inflammation genes upregulated in the intestinal mucosa of obese rats, are downregulated by three probiotic strains.
