DNA ejection from single phage particles

Studying phage, a primitive class of virus that infects bacteria by injecting its genomic DNA into host cells, researchers have gained insight into the driving force behind this poorly understood injection process, which has been proposed in the past to occur through the release of pressure accumulated within the viral particle itself.

New primate-specific gene family that spans about 10% of human chromosome 2

A team of scientists led by Peer Bork, Ph.D., Senior Bioinformatics Scientist at the European Molecular Biology Laboratory, report today in the journal Genome Research that they have identified a new primate-specific gene family that spans about 10% of human chromosome 2.

Researchers have uncovered evidence of sexual reproduction in a single-celled organism long thought to reproduce asexually

The finding by John M. Logsdon, Jr., assistant professor in the UI College of Liberal Arts and Sciences Department of Biological Sciences and the Roy J. Carver Center for Comparative Genomics, and colleagues from the UI and Roanoke College (Virginia), provides the first clear evidence that meiosis arose very early in eukaryotic evolution, bringing science one step closer to understanding the mystery of sexual evolution.

Genomics tools provide clues to what causes 400 million cases of gastrointestinal disease each year

In a study that could benefit medical and food-safety research, scientists have used comparative genomics tools to find clues about why some strains of the bacterium Campylobacter – which each year cause more than 400 million cases of gastrointestinal disease – are more virulent than others.

Possible treatment for the fatal lung disease idiopathic pulmonary fibrosis

They found that the anti-cancer drug imatinib mesylate — commercially known as Gleevec and produced by Novartis Pharmaceuticals — can target a gene critical to controlling the disease process. Previously, there had been no treatment and patients usually did not survive beyond three years of diagnosis. Now the treatment is undergoing clinical trials at Mayo Clinic.

Isis Pharmaceuticals licenses second anti-cancer drug candidate to Lilly

Isis Pharmaceuticals announced today that Eli Lilly and Company licensed LY2275796, a second-generation antisense anti-cancer drug candidate for clinical development.

Potential of genomics in disease research yet to be realized

Over the past decade genomics has revolutionized our understanding of how microorganisms cause disease. However, genomic studies need to be extended to a more diverse array of microorganisms and research tools improved to gain additional insights into pathogenesis, according to a new report released by the American Academy of Microbiology.

Genome decoded of distant relative of human pathogens

The Sanger Institute has completed the sequence and analysis of Erwinia carotovora subsp. atroseptica strain SCRI1043 (ATCC BAA-672).

Three-dimensional cryo-electron microscope may help guide the design of new antibiotics

Understanding the last step of protein synthesis – the basic process of translating DNA into its final protein product – just became more clear both literally and figuratively.

Molecular biologists find chink in the armor of Candida, the most common human fungal pathogen

Molecular biologists at Rice University have discovered a key defense mechanism that the yeast Candida albicans uses against attack by the human immune system.

Comparative genomics to cast new light on other spirochete microbes

Three centuries after a pioneering Dutch microbiologist first observed the spiral-shaped oral pathogen Treponema denticola, scientists have deciphered the bacterium’s entire DNA sequence and used comparative genomics to cast new light on other spirochete microbes.

A debate over the origins of what is sometimes called "junk" DNA has been settled

A debate over the origins of what is sometimes called "junk" DNA has been settled by research involving scientists at the Center for Advanced Research in Biotechnology (CARB) and a collaborator, who developed rigorous proof that these mysterious sections were added to DNA "late" in the evolution of life on earth, after the formation of modern-sized genes, which contain instructions for making proteins.
