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.

microRNA protects red blood cells from oxidant stress: Study

Pediatric researchers have discovered a new biological pathway in which small segments of RNA, called microRNA, help protect red blood cells from injury caused by chemicals called free radicals. The microRNA seems to have only a modest role when red blood cells experience normal conditions, but steps into action when the cells are threatened by oxidant stress.

Researchers create artificial RNA inhibitor to block excess blood cells formation

Researchers at UT Southwestern Medical Center have uncovered a key step in the creation of new red blood cells in an animal study.They found that a tiny fragment of ribonucleic acid (RNA), a chemical cousin of DNA, prompts stem cells to mature into red blood cells. The researchers also created an artificial RNA inhibitor to block this process.

Self assembly approaches to improve DNA sequencing

In an innovation critical to improved DNA sequencing, a markedly slower transmission of DNA through nanopores has been achieved by a team led by Sandia National Laboratories researchers.Solid-state nanopores sculpted from silicon dioxide are generally straight, tiny tunnels more than a thousand times smaller than the diameter of a human hair. They are used as sensors to detect and characterize DNA, RNA and proteins. But these materials shoot through such holes so rapidly that sequencing the DNA passing through them, for example, is a problem.

Scientists identify enzyme to prevent beta-amyloids formation in Alzheimer patients

The brains of Alzheimer patients have high accumulations of the material beta-amyloid, which appear in the form of plaques. The precursors of these plaques are believed to be the underlying cause of the nerve cell loss that leads to the disruptions in memory that characterize Alzheimer's disease. The main aim of many Alzheimer therapies is therefore to inhibit the formation of beta-amyloid. Since beta-amyloid is cleaved from the so-called amyloid precursor protein (APP), scientists have focused on stopping the two enzymes that attack the precursor protein. These act like molecular scissors and cut out the beta-amyloid fragment. Blocking these scissors precludes the formation of beta-amyloid.

Helicos' single-molecule sequencing technology for detection, quantification of novel small RNA

Helicos BioSciences Corporation today announced a publication demonstrating the detection and quantification of novel small RNA molecules using Helicos' single-molecule sequencing technology. These data confirm a long-held, unproven hypothesis that mammalian cells are capable of synthesizing RNA by copying RNA molecules directly.

Researchers discover three disease-causing genes in Salmonella

Researchers have discovered a novel mechanism in Salmonella that affects its virulence and its susceptibility to antibiotics by changing its production of proteins in a previously unheard of manner. This allows Salmonella to selectively change its levels of certain proteins to respond to inhospitable conditions.

Loss of key nerve cells cause Parkinson's disease: Research

Scientists at the Stanford University School of Medicine have identified a molecular pathway responsible for the death of key nerve cells whose loss causes Parkinson's disease. This discovery not only may explain how a genetic mutation linked to Parkinson's causes the cells' death, but could also open the door to new therapeutic approaches for the malady.

Scientists develop laser activated carbon nanoparticles for drug, gene delivery

Using chemical "nanoblasts" that punch tiny holes in the protective membranes of cells, researchers have demonstrated a new technique for getting therapeutic small molecules, proteins and DNA directly into living cells.Carbon nanoparticles activated by bursts of laser light trigger the tiny blasts, which open holes in cell membranes just long enough to admit therapeutic agents contained in the surrounding fluid. By adjusting laser exposure, the researchers administered a small-molecule marker compound to 90 percent of targeted cells - while keeping more than 90 percent of the cells alive.
