Description
Oncogene-induced senescence is an anti-proliferative stress response program that acts as a fail-safe mechanism to limit oncogenic transformation and is regulated by the retinoblastoma protein (RB) and p53 tumor suppressor pathways. We identify the atypical E2F family member E2F7 as the only E2F transcription factor potently upregulated during oncogene-induced senescence, a setting where it acts in response to p53 as a direct transcriptional target. Once induced, E2F7 binds and represses a series of E2F target genes and cooperates with RB to efficiently promote cell cycle arrest and limit oncogenic transformation. Disruption of RB triggers a further increase in E2F7, which induces a second cell cycle checkpoint that prevents unconstrained cell division despite aberrant DNA replication. Mechanistically, E2F7 compensates for the loss of RB in repressing mitotic E2F target genes.

Description
Cellular senescence is a tumor-suppressive program that involves chromatin reorganization and specific changes in gene expression that trigger an irreversible cell-cycle arrest. We have examined the effect of suppressing the histone demethylases Jarid1a and Jarid1b on the senescence-associated gene expression signatures.

Description
During development, lineage specification is controlled by several signaling pathways involving various transcription factors (TFs). Here, we studied the RE1-silencing transcription factor (REST) and identified an important role of this TF in cardiac differentiation. Using mouse embryonic stem cells (ESC) to model development, we analyzed the effect of REST knock-out on the ability to these cells to differentiate into the cardiac lineage. Detailed analysis of specific lineage markers expression showed selective down-regulation of endoderm markers in REST-null cells, thus contributing to a loss of cardiogenic signals.

Description
T cells contribute to host-tumor interactions in patients with monoclonal gammopathies. Expansions of CD8+CD57+TCRV+ restricted cytotoxic T cell (CTL) clones are found in 48% of patients with multiple myeloma and confer a favorable prognosis. We now report the presence of CTL clones with varying TCRV repertoire in 70% of patients with Waldenstroms Macroglobulinaemia (WM) (n=20). Previous nucleoside analogue (NA) therapy, associated with an increased incidence of transformation to aggressive lymphoma, significantly influenced the presence of TCRV expansions (X2=11.6; P<0.001) as 83% of patients without (n=6) and only 7% with TCRV expansions (n=14) had received NA. Clonality of CD3+CD8+CD57+TCRV+ restricted CTLs were confirmed by TCRV CDR3 size analysis and direct sequencing. To characterize CTL clones, samples of CD3+CD8+CD57+TCRV+ cells were profiled using DNA microarrays and the results were validated on both gene and protein level. By gene set enrichment analysis, CTL clones not only expressed genes (GZMB, PRF1, FGFBP2) from cytotoxic pathways but also genes which suppress apoptosis, inhibit proliferation, arrest cell cycle G1/S transition and activate T cells (RAS, CSK and TOB pathways). Proliferation tracking confirmed their anergic state. Our studies demonstrate the incidence, NA sensitivity and anergic nature of clonal T cells in a B cell tumor.
Publication Title
Clonal expansions of cytotoxic T cells exist in the blood of patients with Waldenstrom macroglobulinemia but exhibit anergic properties and are eliminated by nucleoside analogue therapy.

Description
In humans, the most common sex chromosomal disorder is Klinefelter syndrome (KS), caused by the presence of one or more extra X-chromosomes. The KS patients display a diverse adult phenotype with increased height, gynaecomastia, and hypergonadotropic hypogonadism as the most common symptoms. Men with KS are almost always infertile due to testicular degeneration, which accelerates during puberty. Very few studies investigated the global gene expression analysis of adult KS testes and, more importantly, which cell types the differentially expressed transcripts originate from. Transcriptome analysis by RNA sequencing of fixed and paraffin embedded testes originating from 3 adult KS samples and 3 adult cellularity-matched controls revealed 236 differentially expressed transcripts in the adult KS testis. To examine the cellular origin of the differentially expressed transcripts, transcriptome profiling was also carried out on 4 testes with Sertoli Cell-Only and 4 testes with full spermatogenesis. Also, pre-pubertal KS and controls were RNA-sequenced. Overall design: Includes a total of 22 testis samples. 3 adult Klinefelter, 3 Klinefelter-like, 4 Sertoli Cell-Only, 4 with full spermatogenesi, 4 pre-pubertal Klinefelter and 4 pre-pubertal controls
