To explore the primary cause of Dilated Cardiomyopathy in heart samples from DCM-diagnosed patients who had undergone heart transplant (hDCM), we set out to identify differentially expressed genes by massively parallel sequencing of heart samples. Overall design: Methods: Heart mRNA profiles from DCM-diagnosed patients who had undergone heart transplant (hDCM) were generated by deep sequencing, in triplicate, using Illumina GAIIx.

View SamplesTo explore the primary cause of Dilated Cardiomyopathy in Bmi1-null mice, we set out to identify differentially expressed genes by massively parallel sequencing of heart samples from Bmi1f/f;aMHCTM-Cretg/+ mice versus aMHCTM-Cretg/+ control mice (17 weeks postinduction). Overall design: Methods: Heart mRNA profiles of 17-weeks post-induction Bmi1f/f; MHCTM-Cretg/+ mice and MHCTM-Cretg/+ control mice were generated by deep sequencing, in triplicate, using Illumina GAIIx. Sequence reads were pre-processed with Cutadapt 1.2.1, to remove TruSeq adapters and mapped on the mouse transcriptome (Ensembl gene-build GRCm38.v70) using RSEM v1.2.3. The Bioconductor package EdgeR was used to normalize data with TMM and to test for differential expression of genes using GLM.

View SamplesOur studies identify a mechanism of signaling crosstalk during valve morphogenesis that sheds light on the origin of congenital heart defects associated with reduced Notch function. Overall design: Aortic and pulmonary cardiac valves were isolated by laser microdissection from WT and Jag1flox;Nkx2.5-Cre mouse embryos at stage E14.5, and their expression profile characterized by RNA-Seq.

View SamplesFloral organs, whose identity is determined by specific combinations of homeotic genes, originate from a group of undifferentiated cells called the floral meristem. In Arabidopsis, the homeotic gene AGAMOUS (AG) terminates meristem activity and promotes development of stamens and carpels.

View SamplesRheumatoid arthritis is an autoimmune disease in which joint inflammation lead to progressive cartilage and bone destruction. Matrix metalloproteinases (MMP) implicated in homeostasis of extracellular matrix (ECM) play a central role in cartilage degradation. The aim of this study was to investigate the role of MMP-8 (collagenase-2) suppression in the K/BxN serum-transfer arthritis model.
Matrix metalloproteinase-8 deficiency increases joint inflammation and bone erosion in the K/BxN serum-transfer arthritis model.

View SamplesA. thaliana plants were grown in 1/2 MS medium in the presence of carbenicillin (10 µg·mL-1) for 1 or 7 days and RNA from their roots extracted and sequenced in Illumina HiSeq 2000/5000 (2x50 bp). Overall design: Total RNA obtained from A. thaliana roots grown in the absence (mock) or presence of carbenicillin (10 µg·mL-1) for 1 or 7 days. Three replicas per experiment.

View SamplesDiamond-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
