Affymetrix Human Genome U133A Array (hgu133a)
Description
Dilated cardiomyopathy (DCM) is a common cause of heart failure and a leading cause of cardiac transplantation in western countries. The robust predictive expression profile of cardiomyopathic and NF hearts as well as the functional classification can help to identify promising candidates for DCM and may improve the early diagnosis of cardiomyopathy.
Publication Title
Identification of a common gene expression signature in dilated cardiomyopathy across independent microarray studies.

- Affymetrix Poplar Genome Array (poplar)
Description
The molecular responses of Grey poplar (Populus x canescens) following root hypoxia were studied in roots and leaves using transcript profiling. Grey poplar is a flooding tolerant tree species and analysis of the molecular response to hypoxia may indicate possible adaptation mechanisms to this stress.
Publication Title
Differential response of gray poplar leaves and roots underpins stress adaptation during hypoxia.

Description
The pathogenesis of diffuse large B cell lymphomas (DLBCL) is only partly understood. We analyzed 148 DLBCL by high resolution single nucleotide polymorphism (SNP)-chips to characterize genomic imbalances. Seventy-nine cases were of the germinal center B-cell like (GCB) type of DLBCL, 49 of the activated B-cell like (ABC) subtype and 20 were type 3 DLBCL. Twenty-four regions of recurrent genomic gains and 38 regions of recurrent genomic losses were identified over the whole cohort, with a median of 25 imbalances per case for ABC-DLBCL and 19 per case for GCB-DLBCL. Several recurrent copy number changes showed differential frequencies in the GCB- and ABC-DLBCL subgroups, including gains of HDAC7A predominantly in GCB-DLBCL (38% of cases) and losses of BACH2 and CASP8AP2 predominantly in ABC-DLBCL (35%), hinting at disparate pathogenetic mechanisms in these entities. Correlating gene expression and copy number revealed a strong gene dosage effect in all tumors, with 34% of probesets showing a concordant expression change in affected regions. Two new potential tumor suppressor genes emerging from the analysis, CASP3 and IL5RA, were sequenced in 10 and 16 candidate cases, respectively. However, no mutations were found, pointing to a potential haploinsufficiency effect of these genes, considering their reduced expression in cases with deletions. This work thus describes differences and similarities in the landscape of genomic aberrations in the DLBCL subgroups in a large collection of cases, confirming already known targets, but also discovering novel copy number changes with possible pathogenetic relevance.

- Affymetrix Human Gene 2.0 ST Array (hugene20st)
Description
We conducted an in vivo genome-wide CRISPR activation screen to identify genes that accelerate distal metastasis by breast cancer patient-derived circulating tumor cells (CTCs) following direct intravascular inoculation in mice. Regulators of translation and ribosomal proteins were prominent among these, and expression of RPL15, a component of the large ribosome subunit, was sufficient to increase metastatic growth in multiple organs. RPL15 overexpression selectively increases translation of other ribosomal proteins and cell cycle regulators. Unsupervised analysis of single-cell RNA sequencing of freshly-isolated CTCs from breast cancer patients identifies a subset with strong ribosomal and protein translation signatures, correlated with increased proliferative markers, epithelial markers and poor clinical outcome. Thus, ribosome protein expression identifies an aggressive subset of CTCs, whose therapeutic targeting may suppress metastatic progression.

Description
Analysis of effect of long-term cryopreservation on peripheral blood mononuclear cells at gene expression level. The hypothesis tested in the present study was that long-term cryopreservation has an influence on the transcriptome profile of peripheral blood mononuclear cells. Results indicated remarkable changes in expression patterns upon cryopreservation of PBMCs, with decreasing signal intensities over time.
