Description
The Wnt/beta-catenin signalling pathway plays a central role in mammary stem cell homeostasis and in breast cancer. We employed the CD29hiCD24+ cell surface antigens to identify a subpopulation of mammary CSCs from Apc1572T/+, a mouse model for metaplastic breast adenocarcinoma, a subtype of triple-negative breast cancer in man. The MaCSCs are capable of recapitulating tumorigenesis when transplanted at low multiplicities in vivo, and of forming self-renewing organoids in vitro. Expression profiling of the different subpopulations sorted from normal and neoplastic mammary tissues revealed that the normal stem cell compartment is more similar to tumor cells than to their own differentiated progenies. Accordingly, Wnt signaling was found to be activated in the subpopulation encompassing normal mammary stem cells, though to a lesser degree than in the tumor cells. By comparing normal with cancer mouse mammary compartments, we were able to derive a MaCSC-specific signature composed of human orthologous genes able to predict poor survival, relapse and distant metastasis in human breast cancer. Finally, upon intravenous injection, only MaCSCs among the different tumor cell subpopulations are able to form metastatic lesions in a broad spectrum of anatomical sites. Overall, our data indicate that constitutive Wnt signaling activation interferes with mammary stem cell homeostasis leading to metaplasia and basal-like adenocarcinomas.

Description
The purpose of this study is to understand the effects of adrenergic signaling on the transcriptome of cell line models postulated to be the cells of origin of epithelial ovarian cancers using RNA-Seq. Here we explored the effects of the stress-related hormone, norepinephrine, on normal human ovarian and fallopian tube surface epithelial cellss. We investigated the early transcriptional response to norepinephrine in normal immortalized ovarian surface epithelial cells and fallopian tube secretory cells. RNA-Seq data of treated and untreated cells were analyzed to identify genes with differential expression. Overall design: RNA-seq data from ovarian surface epithelial cells and fallopian tube epithelial cells after treatment with 1µM norepinephrine for 1 hour (or mock-treatment). Three independent replicates were performed for each condition and cell line.

Description
The goal of this study is to perform RNAseq in different sub-types of the zebrafish embryonic dorsal aorta (DA) at 28-30 hpf using TgBAC(runx1P2:Citrine);Tg(kdrl:mCherry) double-transgenic zebrafish embryos. A min. of 3000 cells per population were collected via FACS. RNA was isolated with the RNeasy Plus Micro Kit (QIAGEN, Cat No. 74034). High quality RNA (RIN > 8.0) was sent for RNAseq to the Wellcome Trust Centre for Human Genetics (WTCHG). 2.2 ng of total RNA was used to generate SMARTer libraries for low-input RNA. Sequencing was performed on an Illumina HiSeq4000 machine with a 75 bp paired end protocol. Sequenced reads were checked for base qualities, trimmed where 20% of the bases were below quality score 20, and filtered to exclude adapters using Trimmomatic (Version 0.32). Sequences were aligned to the Zebrafish Genome Zv10 with STAR with default parameters. Aligned read features were counted using Subread tool: featureCounts method (version 1.4.5-p1). To determine number of mapped reads we used the trimmed data. The alignment has been performed using STAR with default parameters. The number of mapped reads (QC-passed reads count) has been obtain using Samtools mapping statistics (flagstat tool). Overall design: Analysis of 5 different cell types; DN (double negative), SP-kdrl (single positive), DP-R1lo (double positive runx1 low expression), DP-R1med (runx1 medium expressionand) and DP-R1hi (runx1 high expression) in non-injected (Wt) TgBAC(runx1P2:Citrine);Tg(kdrl:mCherry) double-transgenic zebrafish embryos. Analysis was also done of the DN and DP-R1hi populations in runx1-morpholino (MO) injected embryos.

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.

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.
