Description
Genetically engineered mice developed spontaneous pancreas cancer (Pdx-Cre;LSL-KRASG12D;P53Mut). Mice were also engineered to develop similar spontaneous pancreas cancer without Twist or Snail (conditional gene knockout). The pancreas tumors were harvested and analysed for gene expression profiles comparisons.

Description
In this study Panc-1 cells and BxPC-3 cells were cultured. The cells were harvested (untreated control 'cont') for RNA extraction, or treated for 3 hours with various exosomes preparations. The exosomes were collected from BJ human foreskin fibroblast culture supernatant without further processing (control exosomes or 'CE'), or engineered to contain scrambled siRNA ('scr') or KRASG12D siRNA ('iExo). Two or three distinct wells of cells were evaluated per treatment condition and assigned a well number (well -1, -2 or 3).

Description
Regulatory T (Treg) cells play an indispensable role in immune homeostasis. The development and function of Tregs are dependent on transcriptional factor Foxp3, but how constant expression of Foxp3 is maintained in Tregs is not clear. Here we show that ablation of the conserved non-coding DNA sequence 2 (CNS2) at the Foxp3 locus in mice led to spontaneous lymphoproliferative disease and exacerbation of experimental autoimmune encephalomyelitis (EAE). CNS2 is required for activated Treg cells to maintain elevated Foxp3 expression, which is critical for their suppressor function and lineage stability. Mechanistically, upon TCR stimulation, NFAT binds to both CNS2 and Foxp3 promoter and mediates the interaction between CNS2 and Foxp3 promoter. Our findings demonstrated an essential role for CNS2 in maintaining the stability and function of activated Treg cells and identified NFAT as a key mediator of its function. Overall design: Gene expression was profiled in T regulatory cells (Treg) in WT and CNS2 knockout mice. CNS2 knockout mice lack a conserved non-coding DNA sequence 2 (CNS2) at the Foxp3 locus. Treg cells were further sorted into Foxp3-high and Foxp3-low populations based on the expression level of Foxp3. mRNA was profiled using RNA-Seq (unstranded, polyA+, SE100) in replicate for each condition

affy_pop_2011_08 - poplar bent study - genes regulated by PtaZFP2 in absence of mechanical stress - genes regulated by PtaZFP2 after one bending.Species: Populus tremula x Populus alba-- The laboratory previously established a poplar transgenic line overexpressing PtaZFP2 under the control of an estradiol-inducible promoter. - the experiment, conducted on 3-month-old hydroponically-grown poplars, consists in the comparison of WT poplars treated with estradiol and the PtaZFP2-overexpressing line treated with estradiol. We also compared unbent and bent PtaZFP2-overexpressing poplars. The applied strain is quantitatively controlled (Coutand & Moulia, 2000, JExpBot; coutand et al., 2009, Plant Physiology) -

Description
Type I low-grade gliomas (LGGs), characterized by 1p/19q co-deletions and IDH1/2 mutations, show superior overall survival compared to other gliomas. Approximately 70% of cases harbour mutations in the Capicua (CIC) gene, whose product is a transcriptional repressor whose transcriptional network has yet to be extensively studied in human cells. To address this, we developed CIC knockout cell lines and used transcriptome analyses to study the consequences of CIC loss. Results were further compared to data for Type I LGGs and stomach adenocarcinomas from The Cancer Genome Atlas (TCGA). We find that CIC appears to regulate the expression of genes involved in cell-cell adhesion and nervous system development. CIC deficiency is also found to be associated with a MEK activation transcriptional signature and to act as an effector of MEK signalling. Loss of CIC may thus present a novel mechanism for the dysregulation of this and other oncogenic pathways.

Comparative transcriptome analysis of isogenic cell line models and primary cancers links capicua (CIC) loss to activation of the MAPK signalling cascade.
