TranscriptomicsImpact of ectopic expression of SNAIL2, ZEB2, ZEB1 or TWIST1 on BRAF-target genes in the murine melanocytic melan-a cell line
We have demonstrated that the oncogenic activation of B-RAF (using a truncated delta-BRAF-ER version inducible with tamoxifen) in the melan-a melanocyte cell line triggers the activation of Zeb1 and Twist1 at the expanse of Zeb2 and Snail2. Enforced maintenance of Zeb2 or Snail2 expression reduces t...

TranscriptomicsMicroarray gene expression profiling in central neurocytomas
Microarray gene expression profiling of central neurocytomas (CNs). Comparison between neurocytoma, pineocytoma (PC) and pineoblastoma (PB) relative to normal brain. Gene expression analysis was performed on tumor samples. Tumor tissues of 5 CNs, 2 PCs (low-grade pineal parenchymal tumors (PPTs)) an...

TranscriptomicsMolecular Characterization of Laser Microdissected Circumventricular Organs and Third Ventricle Ependyma in the Adult Rat by Microarray Analysis.
We used LCM and microarrays to analyze the transcriptomes of three CVOs, the SCO, the subfornical organ (SFO), and the PG, and the third ventricle ependyma in the adult rat in order to better characterize these organs at the molecular level. Gene expression was performed on laser microdissection of...

TranscriptomicsGenomic alterations of chromosome 11 induce transcriptomic dysregulation in aggressive and malignant prolactin tumours
Pituitary tumors are generally considered as benign. However, many are invasive (45 to 55%) and some are described as aggressive with a high proliferation rate and short post-operative time to recurrence and 0.2% metastasize. The molecular events associated to the progression of the pituitary tumor ...

TranscriptomicsA stemness-related ZEB1-MSRB3 axis governs cellular pliancy and cancer genome stability.
Genomic instability is a prominent driver of tumorigenesis. However, a significant fraction of human cancers display few genomic aberrations, suggesting alternative roads towards malignancy. Here, we show that the differentiation status of normal human mammary epithelial cells influences the early r...

TranscriptomicsEMT inducers catalyze malignant transformation of mammary epithelial cells and drive tumorigenesis towards claudin-low tumors [mouse]
The newly identified claudin-low subtype of cancer is believed to represent the most primitive breast malignancies, having arisen from transformation of an early epithelial precursor with inherent stemness properties and metaplastic features. Challenging this hypothesis, we show both in vitro and in...

TranscriptomicsTranscriptomic dysregulation in aggressive and malignant prolactin tumours
Pituitary tumours are generally benign. However, many are invasive and some of these are aggressive with high proliferation and recurrence rates. Only metastatic tumours are considered malignant and are rare (0.2%). To identify molecular events associated with the aggressive and malignant phenotypes...

Transcriptomicsgene expression profiling in CD69 positive blood cells selected from Healthy blood Donors and HTLV-1-infected patients
The goal of the study was to identify difference in gene expression between activated /CD69+ blood cells selected from HTLV-1-infected patient displaying HAM-TSP disease (HTLV-1-associated myelopathy/tropical spastic paraparesis), compared to healthy blood donor /HD (biological sample providers: Dr....
