Antisense oligonucleotides (ASO) hold great promise for pharmacotherapy. Now, researchers at Tokyo Medical and Dental University (TMDU) and Ionis Pharmaceuticals, advancing their earlier work on a ...

Researchers from Tokyo Medical and Dental University (TMDU) and Ionis Pharmaceuticals, USA, report a modification wherein replacing the RNA strand of a heteroduplex oligonucleotide with DNA may ...

Antisense oligonucleotides (ASOs) are small, single-stranded molecules that can suppress the expression of targeted genes and thereby achieve therapeutic effects. However, many ASO-based drug ...

Getting therapeutic drugs past the blood-brain barrier has long been a major challenge in treating brain diseases. Now, researchers have explored how cholesterol-modified heteroduplex oligonucleotides ...

Even those who doubt the RNA World hypothesis may be hard-pressed to argue against it. Consider the predicament faced by a team of scientists at Scripps Research. They suspected that RNA was a poor ...

Scientists have unveiled QT45, a 45-nucleotide RNA enzyme that can copy itself and its complementary strand in icy, salty conditions resembling those on early Earth. Its small size makes spontaneous ...

RNA, or ribonucleic acid, is a essential biological molecule that plays a crucial role in various cellular processes. It is a polymeric molecule composed of nucleotides, each containing a ribose sugar ...

Scientists have created QT45, a 45-nucleotide RNA enzyme that can copy itself and its complementary strand in icy, salty conditions thought to resemble early Earth. The finding narrows a long-standing ...

Nucleic acids are complex biological molecules that store and transmit genetic information in all living organisms. They are essential for the survival and reproduction of life on Earth. The two main ...

Researchers have devised a molecular structural modification that boosts the efficacy of antisense oligonucleotide-based drugs by replacing the RNA strand of a heteroduplex oligonucleotide with DNA.
