Oligonucleotides News and Research

RSS

Oligonucleotides are short sequences of nucleotides (RNA or DNA), typically with twenty or fewer bases. Automated synthesizers allow the synthesis of oligonucleotides up to 160 to 200 bases.

Profoundly important discovery of differences in heart's precursor cells

Scientists have long thought that the cells that ultimately give rise to the heart all respond to the same cue before turning into the muscle tissue of this vital organ.

New potential approach to treat spinal muscular atrophy

In the neuromuscular disease called spinal muscular atrophy, or SMA, a protein deficiency caused by a single gene mutation leads to serious damage in growing nerve cells and the muscles they control.

Deadly genetic disease prevented before birth in zebrafish with genetic patch

By injecting a customized "genetic patch" into early stage fish embryos, researchers at Washington University School of Medicine in St. Louis were able to correct a genetic mutation so the embryos developed normally.

Potential method for repairing misspelling in DNA code that causes spinal muscular atrophy

Researchers at the University of Delaware have discovered a novel technique - that acts like a "spell-checker" for correcting a misspelling in the DNA code - to repair the defective gene that causes spinal muscular atrophy (SMA).

ClC-1 helps mice get a move on

In addition to the progressive muscle weakness and degeneration common to all forms of muscular dystrophy, patients with the most common form of muscular dystrophy affecting adults, myotonic dystrophy type 1 (DM1), also experience an inability to voluntarily relax the muscles (a problem known as myotonia).

New target for Hepatocellular carcinoma therapy

Hepatocellular carcinoma (HCC) is a major health problem worldwide. Currently, the only chance for obtaining a cure in patients with HCC is by either a surgical resection or liver transplantation.

eIF4E-specific anti-sense oligonucleotides knock down cancer

A new study by Jeremy Graff and colleagues from Eli Lilly and Company has demonstrated the anti-cancer effect of a new therapeutic in a mouse model of human tumors and has spawned clinical trials to test the ability of this therapeutic to treat human cancers.

Scientists test technique for identifying newly recognized DNA variations that may influence disease risk

Rather than focus on errors and alterations in DNA sequence, the new technique highlights variations in the number of copies of a particular gene.

Nanoparticles yield delivery tools for therapeutic nucleic acids

Cancer researchers hold great hope that nucleic acid-based therapeutics, such as anticancer genes, antisense oligonucleotides, and small interfering RNA (siRNA) molecules, will prove to be powerful antitumor agents.

Nanotechnology continues to advance anticancer gene therapy

Given that cancer is a disease in which genetic errors play a major role, it should come as no surprise that many experts envision a time when gene therapy will play an equally important role in the treatment of cancer.

Co-delivery of drugs and DNA from cationic core-shell nanoparticles self-assembled from a biodegradable copolymer

Efforts to treat cancer using genes and other oligonucleotides, such as short interfering RNA (siRNA), that turn off the biochemical processes that trigger malignancies have been hindered by difficulties in delivering nucleic acids to tumors.
