Affymetrix Human Genome U133A Array (hgu133a)
Description
These data, combined with other cohorts (GSE6532, GSE12093, and qRT-PCR based cohorts), was used to construct the EP algorithm, which predicts the likelihood of developing of a distant recurrence of early stage breast cancer under endocrine treatment. In addition, EPclin, a combination of the EP score, the nodal status and the tumor size, was constructed.
Publication Title
A new molecular predictor of distant recurrence in ER-positive, HER2-negative breast cancer adds independent information to conventional clinical risk factors.

Description
Myelodysplastic syndromes (MDS) are a heterogeneous group of hematopoietic stem cell diseases characterized by dysplasia of one or more hematologic lineages and a high-risk of developing acute myeloid leukemia (AML). MDS patients have recurrent bacterial infections and abnormal expression of CD56 by monocytes. We investigated MDS patients’ bone marrow CD56+/CD56- monocytes and their in vitro derived dendritic cell (DCs) populations in comparison to cells obtained from disease-free subjects. We found that monocytes from MDS patients, irrespective of CD56 expression, have reduced phagocytosis activity and low expression of genes involved in triggering immune responses, regulation of immune and inflammatory response signaling pathways, and in the response to lipopolysaccharide. Dendritic cells (DCs) derived in vitro from MDS monocytes failed to develop dendritic projections and had reduced expression of HLA-DR and CD86 suggesting that antigen processing and T cell activation capabilities are impaired. In conclusion, we identified in both CD56+ and CD56- monocytes from MDS-patients several abnormalities that may be related to the increased susceptibility to infections observed in these patients.

Description
Comparing WT mice to a mouse model of mental retardation, this work identifies genes which display differences in ribosome-bound mRNAs, in hippocampus CA1 pyramidal cells. These genes products are potent functional components of neuronal plasticity and hippocampus-dependent memory. Overall design: Using a triple transgenic mouse line, we immunoprecipitated the HA-Rpl22 protein to isolate and sequence ribosome-associated mRNA in CA1 pyramidal cells. Pairwise comparison of wild type and Fmr1 KO mice defined a specific gene expression profile.

Description
The function of Structural maintenance of chromosome flexible domain containing 1 (Smchd1) was examined during mouse preimplantation development using an siRNA knockdown approach. Transient SMCHD1 deficiency during the period between fertilization and morula/early blastocyst stage compromised embryo viability and resulted in reduced cell number, reduced embryo diameter, and reduced nuclear volumes at the morula stage. RNAseq analysis of Smchd1 knockdown morulae revealed aberrant increases in expression of mRNAs related to the trophoblast lineage, indicating SMCHD1 inhibits trophoblast lineage gene expression and promotes inner cell mass formation. siRNA knockdown also reduced expression of cell proliferation genes, including S-phase kinase-associated protein 2 (Skp2). Smchd1 expression was elevated in Caudal type homeobox transcription factor 2 (Cdx2)-/- blastocysts, indicating enriched expression, and further indicating a role in inner cell mass development. These results indicate that Smchd1 plays dual roles in the preimplantation embryo, promoting a lineage-appropriate pattern of gene expression supporting inner cell mass formation, whilst controlling lineage formation and gene expression in the trophectoderm. Overall design: Effects of SMCHD1 siRNA knockdown were tested in mouse embryos
