Dissecting the Unique Role of the Retinoblastoma Tumor Suppressor during Cellular Senescence

TLDR
It is demonstrated that RB preferentially associates with E2F target genes involved in DNA replication and is uniquely required to repress these genes during senescence but not other growth states, which leads to RB loss leading to inappropriate DNA synthesis following a senescences trigger and enables extensive proliferation and rampant genomic instability.

Comprehensive molecular portraits of human breast tumours

Daniel C. Koboldt, +355 more
- 04 Oct 2012 - 
TL;DR: The ability to integrate information across platforms provided key insights into previously defined gene expression subtypes and demonstrated the existence of four main breast cancer classes when combining data from five platforms, each of which shows significant molecular heterogeneity.

Senescence-Associated Secretory Phenotypes Reveal Cell-Nonautonomous Functions of Oncogenic RAS and the p53 Tumor Suppressor

TL;DR: Coppe et al. as mentioned in this paper showed that human cells induced to senesce by genotoxic stress secrete myriad factors associated with inflammation and malignancy, including interleukin (IL)-6 and IL-8.
Journal ArticleDOI

The essence of senescence

TL;DR: The various features of cellular senescence are reviewed and their contribution to tumor suppression is discussed and the power and limitations of the biomarkers currently used to identify senescent cells in vitro and in vivo are highlighted.
Journal ArticleDOI

Cellular senescence: from physiology to pathology.

TL;DR: In cancer and during active tissue repair, pro-senescent therapies contribute to minimize the damage by limiting proliferation and fibrosis, respectively, and antisenescent therapies may help to eliminate accumulated senescent cells and to recover tissue function.
Journal ArticleDOI

The clonal and mutational evolution spectrum of primary triple-negative breast cancers

TL;DR: It is shown that understanding the biology and therapeutic responses of patients with TNBC will require the determination of individual tumour clonal genotypes, and for the first time in an epithelial tumour subtype, the relative abundance of clonal frequencies among cases representative of the population is determined.

Cluster analysis and display of genome-wide expression patterns

TL;DR: A system of cluster analysis for genome-wide expression data from DNA microarray hybridization is described that uses standard statistical algorithms to arrange genes according to similarity in pattern of gene expression, finding in the budding yeast Saccharomyces cerevisiae that clustering gene expression data groups together efficiently genes of known similar function.

Model-based Analysis of ChIP-Seq (MACS)

TL;DR: This work presents Model-based Analysis of ChIP-Seq data, MACS, which analyzes data generated by short read sequencers such as Solexa's Genome Analyzer, and uses a dynamic Poisson distribution to effectively capture local biases in the genome, allowing for more robust predictions.

DAVID: Database for Annotation, Visualization, and Integrated Discovery

TL;DR: DAMID is a web-accessible program that integrates functional genomic annotations with intuitive graphical summaries that assists in the interpretation of genome-scale datasets by facilitating the transition from data collection to biological meaning.

Oncogenic ras Provokes Premature Cell Senescence Associated with Accumulation of p53 and p16INK4a

TL;DR: It is shown that expression of oncogenic ras in primary human or rodent cells results in a permanent G1 arrest, and that the onset of cellular senescence does not simply reflect the accumulation of cell divisions, but can be prematurely activated in response to an onCogenic stimulus.

Cellular senescence: when bad things happen to good cells

TL;DR: Understanding the causes and consequences of cellular senescence has provided novel insights into how cells react to stress, especially genotoxic stress, and how this cellular response can affect complex organismal processes such as the development of cancer and ageing.
