(Submitter supplied) Aberrant cell proliferation, a hallmark of most cancers, requires the escape from intrinsic antitumour barriers. Primary among these is the DNA damage response (DDR). In both cell culture-models and in early stages of tumorigenesis in vivo, activated oncogenes induce DNA replication stress and DNA double-strand breaks (DSBs), leading to DDR activation and p53-dependent apoptosis and/or senescence. The means by which tumour initiating cells, also termed cancer stem cells (CSCs), circumvent this oncosuppressive response is unknown. more...

(Submitter supplied) 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 vivo that transcription factors inducing epithelial-mesenchymal transition can drive the development of claudin-low tumors from differentiated mammary epithelial cells, by playing a dual role in cell transformation and dedifferentiation.

(Submitter supplied) MaSC, Luminal progenitor enriched subpopulations were isolated from virgin and pregnant mice based on using both surface marker or internal reporter transgene (GFP) expression. (Tiede BJ et al., 2009, PLoS ONE 4(11): e8035. doi:10.1371/journal.pone.0008035), and the transcirptome profiles were determined and compared.

(Submitter supplied) Using an in vitro model for malignant transformation of human bronchial epithelial cells (HBECs) we have found epithelial-to-mesenchymal transition (EMT) and expression of the EMT-transcription factor ZEB1 are early and critical events. Specifically, we found preexisting oncogenic mutations in TP53 and KRAS were required for HBECs to engage EMT machinery in response to microenvironmental (serum/TGFβ) or specific oncogenetic (MYC) EMT-inducing factors, which induce EMT through distinct TGFβ-dependent and vitamin D receptor (VDR)-dependent pathways, respectively, with both requiring ZEB1. more...

(Submitter supplied) This study used tumour and paired normal samples from 28 Sézary Syndrome (SS) patients to define recurrent regions of chromosomal aberrations. Our data identified recurrent losses of 17p13.2-p11.2 and 10p12.1-q26.3 occurring in 71 and 68% of cases respectively; common gains were detected for 17p11.2-q25.3 (64%) and chromosome 8/8q (50%). Moreover, we identified novel genomic lesions recurring in more than 30% of tumours: loss of 9q13-q21.33 and gain of 10p15.3-10p12.2. more...

(Submitter supplied) This SuperSeries is composed of the SubSeries listed below. Zinc finger E-box binding protein 1 (ZEB1) and ZEB2 induce epithelial-mesenchymal transition (EMT) and cancer progression. However, little is known about global picture of transcriptional regulation by ZEB1 and ZEB2. Here we identified an inflammatory phenotype regulated by ZEB1 using chromatin immunoprecipitation-sequencing (ChIP-seq) and RNA-sequencing (RNA-seq) in basal type breast cancer cells, followed by gene set enrichment analysis (GSEA) of ZEB1-bound genes.

(Submitter supplied) MicroRNAs are likely to play pivotal roles in both stem cells and cancer, and are further promising candidates for future therapeutic purposes. To understand the role of miR206 in mammary cell differentiation, we profiled the transcription of mamary stem-like cells, comparing control HC11 cells (unspecific miRNA mimic treated) with HC11 cells transfected with miRNA-206 mimic.
