TranscriptomicsDynamics of MBD2 deposition across methylated DNA regions during malignant transformation of human mammary epithelial cells (3)
DNA methylation is thought to induce a transcriptional silencing through the combination of two mechanisms: the repulsion of transcriptional activators that do not recognize their binding sites when methylated, and the recruitment of transcriptional repressors that specifically bind methylated DNA. ...

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...

TranscriptomicsAntagonistic regulation of EMT by TIF1γ and Smad4 in mammary epithelial cells
TGFβ is known to be a potent inducer of EMT, a process involved in tumor invasion. TIF1γ has been reported to participate to TGFβ signaling. In order to understand the role of TIF1γ in TGFβ signaling and its requirement for EMT, we analyzed the TGFβ1 response of human mammary epithelial cell lines. ...

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...

TranscriptomicsGene expression profiles of p53 depleted human mammary epithelial cells with their Ras-infected epithelial and mesenchymal derivatives
The epithelial-mesenchymal transition (EMT) is an embryonic transdiffrentiation program which consists of the conversion of polarized epithelial cells into a motile mesenchymal phenotype. EMT is aberrantly reactivated during tumor progression, promoting metastatic dissemination. Herein, we demonstra...

ProteomicsPrimary myeloid cell proteomics and transcriptomics: importance of β-tubulin isotypes for osteoclast function
Among hematopoietic cells, osteoclasts (Oc) and immature dendritic cells (Dc) are closely related myeloid cells with distinct functions; Oc participate skeleton maintenance while Dc sample the environment for foreign antigens. Such specificities rely on profound modifications of gene and protein exp...
