Ribonucleic acid (RNA) is a biologically important type of molecule that consists of a long chain of nucleotide units. Each nucleotide consists of a nitrogenous base, a ribose sugar, and a phosphate.

Study identifies 190 proteins crucial to the functions of key immune sensors

In a healthy immune system, invading pathogens trigger a cascade of alerts and responses to fight off the infection. Sensors called toll-like receptors, or TLRs, act as one of the first lines of defense. Two of these sensors, known as TLR7 and TLR9, specifically recognize and respond to microbial RNA and DNA, respectively. But what determines how these TLRs get where they need to be and sound the alarm for pathogen infection?

New work describes communities of active bacteria harbored by honey bee colonies

A novel study of honey bee genetic diversity co-authored by an Indiana University biologist has for the first time found that greater diversity in worker bees leads to colonies with fewer pathogens and more abundant helpful bacteria like probiotic species.

Researchers identify genetic signature for eosinophilic esophagitis

Researchers have identified a genetic signature for a severe, often painful food allergy – eosinophilic esophagitis – that could lead to improved diagnosis and treatment for children unable to eat a wide variety of foods.

Researchers determine structure of concentrative nucleoside transporter

A team of researchers at Duke University has determined the structure of a key molecule that can carry chemotherapy and anti-viral drugs into cells, which could help to create more effective drugs with fewer effects to healthy tissue.

Researchers produce extensive catalog of genes expressed in human islets

A new JDRF-funded study shows that many of the genes known to play a role in type 1 diabetes (T1D) are expressed in pancreatic beta cells, suggesting that the cell responsible for producing insulin may be playing a part in its own destruction to lead to T1D.

GenMark Diagnostics fourth quarter revenues increase to $2.0M

GenMark Diagnostics, Inc. today reported preliminary financial results for the fourth quarter and fiscal year ended December 31, 2011. The Company will release its full financial statements and related disclosures along with its Form 10-K filing for the period ending December 31, 2011 upon completion of its independent audit, which includes the Company's first Sarbanes-Oxley audit of internal controls, by March 15, 2012.

HDAC inhibitors flush latent HIV infection from hiding

A team of researchers at the University of North Carolina at Chapel Hill have successfully flushed latent HIV infection from hiding, with a drug used to treat certain types of lymphoma.

Illumina launches new highly multiplexed cancer panel

Illumina today introduced the TruSeq Amplicon - Cancer Panel, a highly multiplexed panel that will allow researchers to accurately sequence hundreds of the most relevant cancer loci, even in difficult samples such as formalin-fixed, paraffin embedded (FFPE) tumor samples.

Altogen launches new pancreas-targeted in vivo RNAi transfection system

Altogen Biosystems announced the launch of its new pancreas-targeted in vivo RNAi transfection system in the company's popular in vivo delivery product line for use in laboratories and research facilities for development of new medicines and testing in cells and animals.

New, freely available Web-based program helps predict effect of mutations on mRNA splicing

In a brief paper in the journal Bioinformatics, Brown University researchers describe a new, freely available Web-based program called Spliceman for predicting whether genetic mutations are likely to disrupt the splicing of messenger RNA, potentially leading to disease.

Arrowhead, Axolabs enter into RNAi therapeutics strategic agreement

Arrowhead Research Corporation, a nanomedicine company with development programs in RNAi therapeutics and obesity, and Axolabs GmbH, a custom research organization offering preclinical solutions and consultancy in the field of oligonucleotide therapeutics, today announced that they have entered into a Strategic Alliance and Master Services Agreement.

R-loop formation may drive under-methylation and autoimmunity

Researchers at the University of California, Davis, have figured out how the human body keeps essential genes switched "on" and silences the vast stretches of genetic repeats and "junk" DNA.

Bacteria may be talking to each other with a contact-dependent language

What if bacteria could talk to each other? What if they had a sense of touch? A new study by researchers at UC Santa Barbara suggests both, and theorizes that such cells may, in fact, need to communicate in order to perform certain functions. The findings appear today in the journal Genes & Development.

New link between polyamine regulation and ESC biology

A*STAR scientists have for the first time, identified that precise regulation of polyamine levels is critical for embryonic stem cell (ESC) self-renewal - the ability of ESCs to divide indefinitely - and directed differentiation.

Alternative subunits generate different functional subtypes of RNA polymerases

Indiana University biologists have found that specific types of RNA polymerase enzymes, the molecular machines that convert DNA into RNA, can differ in function based on variation in the parts -- in this case protein subunits -- used to assemble those machines.

Study examines mRNA transcripts in the sperm of fruitflies and humans

It had long been assumed that the human sperm cell's mission in life ended once it had transferred its freight of parental DNA to the egg. More recently however, other components of sperm have been implicated in fertilization, and perhaps even in subsequent embryonic development.

HDAC2 enzyme could be a potential target for new Alzheimer's drugs

MIT neuroscientists have shown that an enzyme overproduced in the brains of Alzheimer's patients creates a blockade that shuts off genes necessary to form new memories. Furthermore, by inhibiting that enzyme in mice, the researchers were able to reverse Alzheimer's symptoms.

Ultrasound-based TE more accurate in detecting hepatic fibrosis

Researchers from the Mayo Clinic confirm that ultrasound-based transient elastography (TE) provides excellent diagnostic accuracy for detecting cirrhosis due to recurrent infection with hepatitis C virus (HCV) infection following liver transplantation.
