Description
The tumoral clone of Waldenstrms macroglobulinemia (WM) shows a wide morphological heterogeneity which ranges from B-lymphocytes (BL) to plasma cells (PC). By means of genome-wide expression profiling we have been able to identify genes exclusively deregulated in BL and PC from WM, but with a similar expression pattern in their corresponding cell-counterparts from CLL and MM, as well as normal individuals. The differentially expressed genes have important functions in B-cell differentiation and oncogenesis. Thus, two of the genes down-regulated in WM-BL were IL4R, which plays a relevant role in CLL B cell survival, and BACH2 that participates in the development of class-switched PC. Interestingly, one of the up-regulated genes in WM-BL was IL6. A set of 4 genes was able to discriminate clonal B-lymphocytes from WM and CLL: LEF1 (WNT/catenin pathway), MARCKS, ATXN1 and FMOD. We also found deregulation of genes involved in plasma cell differentiation such as PAX5 which was overexpressed in WM-PC, and IRF4 and BLIMP1 which were underexpressed. In addition, three of the target genes activated by PAX5 -CD79, BLNK and SYK- were up-regulated in WM-PC. In summary, these results indicate that both PC and BL from WM are genetically different from the MM and CLL cell-counterpart.

Description
Human pluripotent stem cells (hPSCs) tend to acquire genomic aberrations in culture, the most common of which is the trisomy of chromosome 12. Interestingly, trisomy 12 is also prevalent in germ cell tumors (GCTs). Here, we aimed to dissect the cellular and molecular implications of trisomy 12 in hPSCs. A genome-wide gene expression analysis revealed that trisomy 12 profoundly affects the global gene expression profile of hPSCs, inducing a transcriptional program very similar to that of CGTs. Direct comparison of the proliferation, replication, differentiation and apoptosis between diploid and aneuploid hPSCs revealed that trisomy 12 significantly increases the proliferation rate of hPSCs. Increased replication largely accounts for the increased proliferation observed, and may explain the selection advantage that trisomy 12 confers to hPSCs. A comparison of the tumors induced by diploid and aneuploid hPSCs further demonstrated that trisomy 12 increases the tumorigenicity of hPSCs, inducing transcriptionally-distinct teratomas, from which pluripotent cells can be recovered. Lastly, a chemical screen of 89 anticancer drugs against diploid and aneuploid hPSCs discovered that trisomy 12 raises the sensitivity of hPSCs to several replication inhibitors, suggesting that the increased proliferation and tumorigenicity of these aberrant cells also makes them more vulnerable, and might potentially be used for their selective elimination from culture. Together, our findings demonstrate the extensive effect of trisomy 12 on the gene expression signature and on the cellular behavior of hPSCs, and highlight the danger posed by this trisomy for the successful use of hPSCs in basic research and in regenerative medicine.

- Affymetrix Human Gene 1.0 ST Array (hugene10st)
Description
Nucleosomal incorporation of specialized histone variants is an important mechanism to generate different functional chromatin states. Here we report the identification and characterization of two novel primate-specific histone H3 variants, H3.X and H3.Y. Their mRNAs are found in certain human cell lines, in addition to several normal and malignant human tissues. In keeping with their primate-specificity, H3.X and H3.Y are detected in different brain regions. Transgenic H3.X and H3.Y proteins are stably incorporated into chromatin in a similar fashion to the known H3 variants. Importantly, we demonstrate biochemically and by mass spectrometry that endogenous posttranslationally modified H3.Y protein exists in vivo, and that stress-stimuli, such as starvation and cellular density, increase the abundance of H3.Y-expressing cells. Global transcriptome analysis revealed that knock-down of H3.Y affects cell growth and leads to changes in the expression of many genes involved in cell cycle control. Thus, H3.Y is a novel histone variant involved in the regulation of cellular responses to outside stimuli.

Affymetrix Zebrafish Genome Array (zebrafish)
Description
The mammalian heart has poor regenerative capacity following injury. In contrast, certain lower vertebrates such as zebrafish retain a robust capacity for regeneration into adult life. Here we use an integrated approach to identify evolutionary conserved regenerative miRNA-dependant regulatory circuits in the heart. We identified novel miRNA-dependant networks involved in critical biological pathways, which are differentially utilized between the infarcted mouse heart and the regenerating zebrafish heart.
