Roche's xCELLigence RTCA SP Instrument used for in vitro testing of cells

The C-terminal domain (CTD) of RNA Polymerase II consists of multiple repeats of an evolutionary conserved motif of seven amino acids, forming a repetitive structure of 52 repeats in humans and 26 repeats in yeast. Twenty years after the first description of the RNA polymerase II C-terminal domain, its function is still unclear.

New RNA repair and modification system in bacteria discovered

In new papers appearing this month in Science and the Proceedings of the National Academy of Sciences, University of Illinois biochemistry professor Raven H. Huang and his colleagues describe the first RNA repair system to be discovered in bacteria.

Researchers find SNARE-like protein system to help bacteria avoid cell destruction

Infectious diseases currently cause about one-third of all human deaths worldwide, more than all forms of cancer combined. Advances in cell biology and microbial genetics have greatly enhanced understanding of the cause and mechanisms of infectious diseases.

BIOBASE to integrate its TRANSFAC database with CLC bio's popular workbenches

Today at the Biotechnica / Bio-IT World Europe conference in Hannover, Germany, BIOBASE and CLC bio announced a partnership to integrate BIOBASE's comprehensive TRANSFAC® database with CLC bio's popular workbenches and award-winning server solution.

NCI selects Integral Molecular to map epitopes for monoclonal antibodies

Integral Molecular, Inc. has been selected by the National Cancer Institute (NCI) to map epitopes for monoclonal antibodies directed against cancer biomarkers. Protein targets of interest to the Clinical Cancer Proteomics community will be analyzed using Shotgun Mutagenesis Mapping technology to identify amino acids that are essential for antibody binding, allowing the discovery and characterization of cancer-specific biomarkers.

Research to study how eukaryotic cells help in building proteins

Federal stimulus funding is helping a Kansas State University biologist continue to collaborate with the Harvard Medical School. Their research is creating a clearer picture of a certain cellular process that can play a role in chronic diseases like cancer.

Chk1 and Fbx6 play an important role for the regulation of response to chemotherapy

Cell cycle checkpoints act like molecular tripwires for damaged cells, forcing them to pause and take stock. Leave the tripwire in place for too long, though, and cancer cells will press on regardless, making them resistant to the lethal effects of certain types of chemotherapy, according to researchers at the Salk Institute for Biological Studies.

Surprising new insights into the repair strategies of DNA

A microscopic single-celled organism, adapted to survive in some of the harshest environments on earth, could help scientists gain a better understanding of how cancer cells behave.

Research suggests core nuclear pore elements shared by all eukaryotes

For perhaps 1.8 billion years after life first emerged on Earth, a sort of evolutionary writer's block stalled the development of organisms more complicated than single cells. Then, a burst of experimental creativity about 1.7 billion years ago brought the cell nucleus onto the scene, stashing the cell's genetic material inside a protective inner membrane and setting the stage for the evolution of more sophisticated creatures from yeast, say, to plants and human beings.

Cells use import machinery to export their goods as well

In the bustling economy of the cell, little bubbles called vesicles serve as container ships, ferrying cargo to and from the port - the cell membrane. Some of these vesicles, called post-Golgi vesicles, export cargo made by the cell's protein factory.

Statins may be useful in patients with tamoxifen-resistant breast cancer

Breast cancer cells in the laboratory that don't respond to tamoxifen may be producing high amounts of cholesterol in order to provide a kind of shield against the drug, say researchers at Georgetown University Medical Center (GUMC).

When every photon counts: unusual cell nuclei help nocturnal animals see better

The eyes of nocturnal mammals have very large numbers of highly-sensitive rod photoreceptors (the cell type responsible for night vision).

Gene targeting discovery opens door for vaccines and drugs

In a genetic leap that could help fast track vaccine and drug development to prevent or tame serious global diseases, DMS researchers have discovered how to destroy a key DNA pathway in a wily and widespread human parasite.

New RNA-Seq technique used to profile anthrax genome

Scientists at the Georgia Institute of Technology have used a new approach, known as RNA-Seq, to profile the gene expression of the bacterium that causes anthrax, Bacillus anthracis.

Bioinformatics sheds light on evolutionary origin of Rickettsia virulence genes

Scientists from the Virginia Bioinformatics Institute (VBI) at Virginia Tech, the University of Maryland School of Medicine, and the University of Louisville have revealed that genes for a specific type of molecular secretion system in Rickettsia, a structure that is linked in many cases to virulence, have been conserved over many years of evolution.

Discovery of alga that detoxifies arsenic

Arsenic may be tough, but scientists have found a Yellowstone National Park alga that's tougher.

Exploring the roles of noise in the eukaryotic cell cycle

A single cell - whether a yeast cell or one of your cells - is exquisitely sensitive to its surroundings.

Researchers study Actin - a globular protein

Actin, a globular protein found in all eukaryotic cells, is a workhorse that varies remarkably little from baker's yeast to the human body.

From the works of Shakespeare to the genomes of viruses

What does uncovering the true authorship of plays attributed to Shakespeare have to do with identifying our genetic ancestors or classifying new life forms?

E. coli persists against antibiotics through HipA-induced dormancy

Bacteria hunker down and survive antibiotic attack when a protein flips a chemical switch that throws them into a dormant state until treatment abates, researchers at The University of Texas M. D. Anderson Cancer Center report in the Jan.16 edition of Science.
