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.

Study offers promise for therapeutic management of fetal and congenital genetic diseases in utero

A breakthrough study by research teams at Rosalind Franklin University of Medicine and Science and Oregon Health & Science University offers promise for therapeutic management of congenital diseases in utero using designer nucleotide sequences that can simply be injected into the fluid surrounding the developing fetus to potentially treat disabling-to-lethal genetic defects.

Scientists find way to boost efficiency with which CRISPR-Cas9 cuts and disables genes

CRISPR-Cas9 is the go-to technique for knocking out genes in human cell lines to discover what the genes do, but the efficiency with which it disables genes can vary immensely.

Overcoming gene silencing barriers to target neurological conditions: an interview with Dr Errol de Souza

Many gene mutations that cause neurological disorders have been identified. For example, in a rare neurological disorder such as Huntington’s disease, an autosomal dominant mutation through expansion of CAG (cytosine-adenine-guanine) triplet repeats in the gene coding for the Huntingtin protein results in abnormal protein production.

Novel conjugate therapy shows promise in destroying ALL cells with few side effects

Researchers at UC Davis and Ionis Pharmaceuticals have developed a hybrid treatment that harnesses a monoclonal antibody to deliver antisense DNA to acute lymphoblastic leukemia (ALL) cells and that may lead to less toxic treatments for the disease.

Promising new therapeutic target could lead to better prognosis of spinal muscular atrophy

According to studies, approximately one out of every 40 individuals in the United States is a carrier of the gene responsible for spinal muscular atrophy (SMA), a neurodegenerative disease that causes muscles to weaken over time.

Delivering microRNAs in cancer treatment: an interview with Dr Conde and Prof Artzi

microRNAs (miRs) are small endogenous noncoding RNA molecules (20–23 nucleotides) derived from imperfectly paired hairpin RNA structures naturally encoded in the genome that act specifically as triggering molecules to control translational repression or mRNA degradation.

Using Single-Molecule Studies to Understand Cellular Processes: An Interview with Professor W. E. Moerner

Single fluorescent molecules provide a local nanometer-sized probe of complex systems. We can measure the motion of the single molecule, use them to achieve imaging on a scale down to 20 nanometers, or we can infer aspects of the behaviour of the object under study by the details of the light that is emitted.

Study paves way for development of novel cancer therapeutics

A team of scientists, comprising researchers from the Institute of Molecular and Cell Biology, a research institute under the Agency for Science, Technology and Research, Singapore, and the VIB Laboratory of Molecular Cancer Biology, has revealed the mechanism by which tumor cells elevate levels of MDM4, a protein that is highly expressed in cancer cells but not in normal adult tissues.
