Cells protect themselves against viruses and bacteria with novel non-genetic mechanism

When cells are confronted with an invading virus or bacteria or exposed to an irritating chemical, they protect themselves by going off their DNA recipe and inserting the wrong amino acid into new proteins to defend them against damage, scientists have discovered.

Studies examine interaction of ribosome with molecular partners

Two new studies reveal in unprecedented detail how the ribosome interacts with other molecules to assemble new proteins and guide them toward their destination in biological cells. The studies used molecular dynamics flexible fitting (MDFF) to examine the interaction of the ribosome with two prominent molecular partners.

Some combination drug therapies are counter-productive

Combination drug therapy has become a staple for treating many infections. For instance, doctors treat extensively drug resistant forms of tuberculosis with one drug that breaks down the pathogen's protective barriers and opens the door for another to deliver the deathblow.

Novexel commences comparative study of NXL103 to oral linezolid

Novexel, a speciality pharmaceutical company focused on the discovery and development of novel antibiotics designed to overcome the significant global problem of microbial resistance, announces today that its most advanced oral antibacterial NXL103 (flopristin/linopristin), has started a Phase II clinical trial in adults with acute bacterial skin and skin structure infections (ABSSSI). The trial is designed to assess the safety and efficacy of NXL103 in comparison to oral linezolid.

Viral protein could be a major player in SARS virulence

Ever since the previously unknown SARS virus emerged from southern China in 2003, University of Texas Medical Branch at Galveston virologists have focused on finding the source of the pathogen's virulence - its ability to cause disease. In the 2003 epidemic, for example, between 5 and 10 percent of those who fell sick from the SARS virus died, adding up to more than 900 fatalities worldwide.

Study reveals microRNAs affect tumor progression

UCSF researchers have identified collections of tiny molecules known as microRNAs that affect distinct processes critical for the progression of cancer. The findings, they say, expand researchers' understanding of the important regulatory function of microRNAs in tumor biology and point to new directions for future study and potential treatments.

One secret to how tuberculosis resists the host immune system

Mycobacterium tuberculosis is arguably the world's most successful infectious agent because it knows how to avoid elimination by slowing its own growth to a crawl. Now, a report in the July 10 issue of the journal Cell, a Cell Press publication, offers new insight into the bugs' talent for meager living.
