Researchers investigate aberrant expression of nuclear matrix proteins in gastric cancer cells

Gastric cancer is the most common malignant gastrointestinal cancer and accounts for 25% of cancer deaths. Nuclear matrix, a filamentous protein framework for eukaryotic cellular chromatin, closely relates to DNA duplication and transcription. Research on nuclear matrix proteins will provide insight into how tumors developed.

The emerging science of epigenetics

Human embryonic stem cells (hESCs) possess remarkable properties of self-renewal and pluripotency, the ability to become almost any kind of cell within the body. And yet they share the same genome or set of genes with lineage-committed cells, cells fated to be or do one thing.

NIH awards CSU biochemists $7.8M grant to study gene regulation within cells

A team of top biochemists at Colorado State University will investigate how chromosomes untangle to expose genes that dictate cell behavior - a unique project that could have a significant impact on understanding human health.

Deficiency of frataxin protein causes Friedreich's ataxia

The defective gene responsible for Friedreich's ataxia was identified over 20 years ago, but so far our ideas of how this gene causes the disease have been merely speculative. It was assumed that, as a result of the mutation, the gene could no longer be transcribed because this stretch of DNA was inaccessible. FMI Group Leader Marc Bühler and his team have now carried out experiments demonstrating that this is not the case and revealing what actually happens in Friedreich's ataxia.

Genomic component playing key role in promoting breast cancer progression discovered

Life Technologies Corporation today announced that its scientists have teamed with researchers from Stanford University School of Medicine, and other institutions to discover a genomic component that plays a key role in promoting breast cancer progression. A study published today in the journal Nature details how levels of a specific kind of non-coding RNA molecule in primary breast tumors regulate metastasis and tumor invasiveness and may be an important target for cancer diagnosis and therapy.

New methodology helps investigate unfolding of DNA

NYU Langone Medical Center researchers have developed a powerful new method to investigate the discrete steps necessary to turn on individual genes and examine how the process goes wrong in cancer and other diseases. The finding, based on seven years of research and described in the April 9 issue of Molecular Cell, allows scientists to investigate the unfolding of DNA, a process required for gene activation.

Study promises new combination cancer therapy for drug resistance

Results reported in the April 2nd issue of the journal Cell, a Cell Press publication, reveal a new source for the drug resistance that crops up all too often and quickly in the tumors of cancer patients undergoing therapy.

Chromatin expands operations to 5,000 square foot facility in University of Illinois' Research Park

The University of Illinois today announces that Chromatin, Inc., a biotechnology company that has occupied space in the University's Research Park since 2005 as part of the EnterpriseWorks incubator, is expanding operations and graduating to a 5,000 square foot facility in the Research Park. The expansion marks the company's continued significant progress in commercializing its proprietary technology, including mini-chromosomes which were originally developed at the University of Chicago by company co-founder and CEO Daphne Preuss.

Working of master regulator protein phosphatase 1

Protein phosphorylation is a process by which proteins are flipped from one activation state to another. It is a crucial function for most living beings, since phosphorylation controls nearly every cellular process, including metabolism, gene transcription, cell-cycle progression, cytoskeletal rearrangement and cell movement.

MLL cancer cells rely on normal protein to proliferate

Researchers have found that one particularly aggressive type of blood cancer, mixed lineage leukemia (MLL), has an unusual way to keep the molecular motors running. The cancer cells rely on the normal version of an associated protein to stay alive.

Mutations in MeCP2 cause autism spectrum disorder Rett Syndrome

A paper published online today in Molecular Cell proposes that Methyl CpG binding protein 2 (MeCP2) impacts the entire genome in neurons, rather than acting as a regulator of specific genes. Mutations in MeCP2 cause the autism spectrum disorder Rett Syndrome as well as some cases of neuropsychiatric problems including autism, schizophrenia and learning disabilities.

Helicos BioSciences to demonstrate single molecule sequencing using Helicos Genetic Analysis System

Helicos BioSciences and it’s collaborators will deliver presentations featured at the Advances in Genome Biology and Technology (AGBT) meeting in Marco Island, Florida, from February 24-27, 2010.

ES cells-functions: Condensins promote mitotic progression and maintain interphase chromatin compaction

Regulatory proteins common to all eukaryotic cells can have additional, unique functions in embryonic stem (ES) cells, according to a study in the February 22 issue of the Journal of Cell Biology (www.jcb.org). If cancer progenitor cells-which function similarly to stem cells-are shown to rely on these regulatory proteins in the same way, it may be possible to target them therapeutically without harming healthy neighboring cells.

Gene expression in prostate cancer cell more complex than ever imagined

Scientists from Sydney's Garvan Institute of Medical Research have published a paper, online today in Nature Cell Biology, describing gene expression in a prostate cancer cell: more sweeping, more targeted and more complex than we could ever have imagined, even five years ago.

Emerging concepts from gene regulation studies in immune cells

The seventh meeting in the “Emergence and Convergence” series jointly organized by La Fondation IPSEN and Nature brings together today in San Antonio (Texas, USA) leading experts to discuss concepts emerging from gene regulation studies in immune cells that have led to insights into the initiation and maintenance of epigenetic chromatin marks necessary for proper differentiation and function of these cells in the immune system.

Diagenode launches SX-8G IP-Star system for epigenetics

Diagenode, an innovative leader providing products and technologies for epigenetics, genomics and diagnostics, and the only provider of complete epigenetics solutions, announced today the launch of its innovative platform for automated epigenetics assays, the SX-8G IP-Star™ system ("IP-Star™).

Study: Common underlying mechanism causes complex defects in brain development and function

A new study reveals that a common underlying mechanism is shared by a group of previously unrelated disorders which all cause complex defects in brain development and function. Rett syndrome (RTT), Cornelia de Lange syndrome (CdLS) and Alpha-Thalassemia mental Retardation, X-linked syndrome (ATR-X) have each been linked with distinct abnormalities in chromatin, the spools of proteins and DNA that make up chromosomes and control how genetic information is read in a cell.

Study sheds new light on cancer metastasis

Some cells are natural rule-breakers. Neural crest cells for example, not only migrate throughout the body during development (most cells are more selective in their wandering), they are also more developmentally flexible than their predecessors (a no-no for nearly all cell types).
