Description
The goal of this study is to analyse the transcriptome of WT and Myc-overexpressing ESCs in iMOS T1-Myc mosaic cultures. Overall design: Homozygous iMOS T1-Myc ESC cultures (Claveria et al., 2013) were treated with 20µM 4-hydroxytamoxifen for 24 hours to generate a mosaic of cell populations containing two, one or no extra Myc and EYFP copies. 24 hours after tamoxifen removal, cells were sorted according to their EYFP expression levels and populations with two extra Myc and EYFP copies and with no extra Myc and EYFP copies were collected. Uninduced homozygous iMOS T1-Myc ESC cultures were also sorted and collected as a control. Three biological replicas were included for each condition.

Description
Purpose: The goal of this study is to determine whether ectopic expression of the GLI2 transcription factor in the human pancreatic cancer cell line, YAPC is sufficient to cause gene expression changes associated with a EMT switch. Methods: RNA was isolated from YAPC cells engineered to express a doxycycline inducible cassette for ectopic expression of GLI2 following treatment with 1ug/ml of Dox for 6 days. Control YAPC cells expressing an "empty vector" dox inducible cassette were similarly treated for 6 days with 1ug/u Dox and RNA was collected. Three biologically destinct replicates were submitted for library preparation and RNA-sequencing on an Illumina hiseq 2000. The sequence reads that passed quality filters were analyzed at the transcript level using TopHat followed by Cufflinks. qRT–PCR validation was performed using SYBR Green assays Results: RNA-seq data confirmed stable over-expression of GLI2 in the YAPC-rtta-GLI2 cells and not in the EV control cells treated with Dox. Target genes of interest were validated by qRT–PCR. RNA-seq data had a linear relationship with qRT–PCR for all target genes tested. Gene set enrichment analysis of differentially expressed genes showed enrichment of EMT associated pathways which was further validated using functional assays. In addition a statistically significant alteration in SPP1 transcript was discovered in GLI2 overexpressing cells which formed the basis of ongoing experiments in the study. Conclusions: Our data support a role for GLI2 in regulation of genes associated with basal-like subtype switching including SPP1 Overall design: mRNA profiles from human pancreatic cancer cell lines YAPC-rtta-GLI2 and YAPC-rtta-EV treatment with doxycyline for 6 days were compared, in triplicate.

Description
Several studies demonstrated IgVH mutation status and ZAP-70 expression as the most relevant prognostic markers in CLL, suggesting the separation of two patient subgroups: with good (MTZAP-70-) and poor prognosis (UMZAP-70+). We determined gene expression of B cells in 112 CLL patients divided into three classes: the first with IgVHMT and ZAP-70-, the second with IgVHUM and ZAP-70+, and the third included both IgVHUM ZAP-70- and IgVHMT ZAP-70+. We found LPL, AGPAT2, MBOAT1, CHPT1, AGPAT4, PLD1 genes encoding enzymes involved in lipid (glycerolipid/glycerophospholipid) metabolism overexpressed in UMZAP-70+. In addition, this study demonstrates the role of ARSD, a gene belonging to the sphingolipid metabolism, as a new gene significantly overexpressed in UMZAP-70+ in respect to MTZAP-70-. ARSD protein was found at significantly higher concentrations in UMZAP-70+ compared to MTZAP-70- CLL B cells and B cells from healthy individuals by Western blotting. Statistical analysis identified a strong correlation between ARSD and IgVH mutation status; ARSD protein level was associated with the requirement of therapy for CLL patients and for this purpose it is as good as IgVH mutational status. Our study highlights ARSD as a promising new prognostic factor in CLL and sphingolipid metabolism as a putative new biological mechanism in CLL.

Gene expression profiling identifies ARSD as a new marker of disease progression and the sphingolipid metabolism as a potential novel metabolism in chronic lymphocytic leukemia.

Description
TCERG1 is a highly conserved human protein implicated in interactions with the transcriptional and splicing machinery. To investigate TCERG1 function, we survey genome-wide changes in transcript and exon levels upon TCERG1 knockdown in HEK293T cells. Our data revealed that TCERG1 regulates different types of alternative spliced events, indicating a broad role in the regulation of alternative splicing.
