Researchers use computers to capture chemical signal structure that triggers metastatic cancer

In cancer and other pathological diseases, researchers are discovering that packaging is important: specifically, how DNA - about two meters long when unwound and stretched - coils up and compacts neatly inside the nucleus of a cell.

Scientists discover fundamental mechanism behind toxic protein aggregation in neurodegenerative diseases

Protein aggregation underlies several neurodegenerative diseases such as Alzheimer's, Huntington's chorea or Parkinson's. Scientists at the Max Planck Institute of Biochemistry (MPIB) in Martinsried near Munich, Germany, now discovered a fundamental mechanism which explains how toxic protein aggregation occurs and why it leads to a widespread impairment of essential cellular functions.

Researchers identify PBRM1 gene mutation in one in three patients with common form of renal cancer

In a collaborative project involving scientists from three continents, researchers have identified a gene that is mutated in one in three patients with the most common form of renal cancer.

Catalogs of fruit fly and roundworm's functional genomic elements

Scientists today published catalogs of the fruit fly and roundworm's functional genomic elements: DNA sequences in the genome that carry the instructions and determine which genes are turned on and off at various times in different cells.

EpiTherapeutics, Abbott to develop new anti-cancer drugs

EpiTherapeutics and Abbott today announced a collaboration agreement to develop new anti-cancer drugs by making small-molecule inhibitors against selected epigenetic oncology targets.

'Histone code' needs to be used with caution

The function of histones -- the proteins that enable yards of DNA to be crammed into a single cell -- depends on a number of chemical tags adorning their exterior. This sophisticated chemical syntax for packaging DNA into tight little coils or unraveling it again -- called the "histone code" -- is the latest frontier for researchers bent on understanding how genetics encodes life.

New findings says TRIM24 protein plays active role in breast cancer formation

The recently identified TRIM24 protein plays an active role in pushing normal breast cells into rapid cell proliferation and, potentially, into breast cancer.

HDAC inhibitors may be used to fight against skin cancers

In a study published in the journal Developmental Cell, Sarah Millar PhD, professor of Dermatology and Cell & Developmental Biology at the University of Pennsylvania School of Medicine, and colleagues demonstrate that a pair of enzymes called HDACs are critical to the proper formation of mammalian skin.

Multinational team identifies novel retinal disease gene

A multinational team effort of Regensburg's Institute of Human Genetics, Washington University in St. Louis, other partners and Genomatix elucidated a transcriptional network in photoreceptors and thereby identified a novel retinal disease gene

Elevated levels of MCP-1 found in urine of patients with acute kidney injury

The presence of certain markers in the urine might be a red flag for acute kidney injury (AKI), according to a study appearing in an upcoming issue of the Journal of the American Society Nephrology (JASN). The results suggest that a simple urine test could help prevent cases of kidney failure.

Study reveals two enzymes help immune cells deploy pathogen-killing traps

A new study reveals that two enzymes help immune cells deploy pathogen-killing traps by unraveling and using the chromatin (DNA and its associated proteins) contained in the cells' nuclei to form defensive webs. The study appears online on October 25 in The Journal of Cell Biology.

New review outlines Bionovo's platform of estrogen receptor modulators for menopausal conditions

Bionovo, Inc. today announced the publication of a review of results from studies discussing new classes of estrogen receptor modulating drugs with distinct mechanism for pharmacological effect. The review is published in the most recent edition of Current Opinion in Pharmacology.

Scientists identify root cause of chromosomal errors and gene diversity

A team led by a scientist at the University of Pittsburgh School of Medicine has discovered a regulatory protein that influences where genetic material gets swapped between maternal and paternal chromosomes during the process of creating eggs and sperm. The findings, which shed light on the roots of chromosomal errors and gene diversity, appear in tomorrow's issue of Nature.

Gene Biodesign joins Roche NimbleGen Certified Service Provider Program

Roche NimbleGen announced today that Taipei-based genomic services provider Gene Biodesign Enterprises Co. has officially joined the Roche NimbleGen Certified Service Provider (CSP) Program.

Researchers develop new method to identify chemical histone modifications

Test system on Drosophila should provide the key to histone function. The genetic inherited material DNA was long viewed as the sole bearer of hereditary information. The function of its packaging proteins, the histones, was believed to be exclusively structural. Additional genetic information can be stored, however, and passed on to subsequent generations through chemical changes in the DNA or histones. Scientists from the Max Planck Institute for Biophysical Chemistry in Göttingen have succeeded in creating an experimental system for testing the function of such chemical histone modifications and their influence on the organism.

IRSF awards $1.5M in research grants for Rett syndrome treatment

The International Rett Syndrome Foundation (IRSF) announced today that it will award an additional $1.5M in research grants, bringing the 2010 total to $2.15 million for innovative basic and translational research that moves treatments for Rett syndrome a step closer to the clinic.

Cell aging is associated with reduced histone level

Like cats, human cells have a finite number of lives-once they divide a certain number of times they change shape, slow their pace, and eventually stop dividing, a phenomenon called cellular senescence.

Researchers discover new factors that regulate fat formation

By creating a "map" of histone modifications in fat cells, investigators have discovered two new factors that regulate fat formation, a key step on the road to better understanding obesity, diabetes and other metabolic disorders.

Covaris enters co-marketing partnership with Illumina for DNA shearing technologies

Covaris Inc. today announced that it has signed a co-marketing agreement with Illumina, Inc. making Covaris DNA shearing technologies the recommended method of shearing with Illumina next-generation sequencing product lines, including HiSeq, HiScanSQ, and Genome Analyzer.

Researchers synthesize molecule to block abnormal protein in cancer cells

In the quest to arrest the growth and spread of tumors, there have been many attempts to get cancer genes to ignore their internal instruction manual. In a new study, a team led by Dana-Farber Cancer Institute scientists has created the first molecule able to prevent cancer genes from "hearing" those instructions, stifling the cancer process at its root.
