Researchers from Osaka University have used a novel combination of short-read and long-read RNA sequencing to identify the different isoforms of genes expressed in the crustacean Daphnia magna. Males and females are genetically identical, but using this technique the team revealed genes that switch the predominant isoform in a sex-dependent manner. This study contributes to our understanding of Daphnia’s sexual dimorphism and helps further advance technologies in crustacean aquaculture.

Amyotrophic Lateral Sclerosis (ALS) and Frontotemporal Dementia (FTD) are neurodegenerative diseases that commonly occur in middle-aged people. FTD is second only to Alzheimer's disease in terms of dementia prevalence. Both ALS and FTD arise from neuronal degeneration through mechanisms that remain unclear. Dr. Yun-Ru (Ruby) Chen's team in the Genomics Research Center (GRC), Academia Sinica recently discovered a new pathological mechanism for neuronal degeneration using synthetic peptides. They also discovered that a disaccharide can increase neuronal survival and reduce degeneration. The result provides therapeutic strategies for future treatment of these neurodegenerative diseases. The study was published in the top international journal "Science Advances" on February 23, 2024.

Risk-averse on/off-target assessment for CRISPR editing without reference genome
15 Sep 2023
Researchers led by Osaka University developed a novel genome editing technique known as NICER, which results in significantly fewer off-target mutations than CRISPR/Cas9 editing. The technique uses a different type of enzyme that makes single-stranded “nicks” in the DNA. Repair of these nicks is more efficient and accurate than repair of double-strand breaks caused by the current CRISPR/Cas9 editing. This technique represents a novel approach for the treatment of genetic diseases caused by heterozygous mutations.

DNA and RNA, the two main types of nucleic acid and the building blocks of life, are susceptible to environmental stimuli, which can cause them to deform, bend or twist. These deformations can significantly affect gene regulation and protein functions, but they are extremely difficult to measure using traditional techniques. Recently, a research team co-led by a physicist from City University of Hong Kong (CityU) accurately measured the change in a nucleic acid induced by salt, temperature change and stretching force. Their findings help reveal the underlying universal deformation mechanisms of DNA and RNA.

Researchers from Osaka University have demonstrated a proof-of-concept for identifying single nucleotides by using quantum computing. Molecular rotation patterns—and the corresponding variations in conductance—within the nanoscale gap between two electrodes enabled the development of a quantum gate for the nucleotide adenosine monophosphate. Developing quantum gates for the other three nucleotides, and incorporating this technology into DNA sequencing workflows, could revolutionize genome analysis.

New technological development has provided further clues about the origins of life on Earth. An international research group invented an innovative X-ray spectroscopy approach that enabled them to recreate the chemical reactions occurring in liquids at the femtosecond level (a quadrillionth part of a second). They used this to examine ureas—an organic compound that underwent ionization to form some of the building blocks of life.

A team led by researchers from Osaka University elucidated a molecular mechanism that is crucial for separating genetic material into daughter cells during cell division. A protein called CENP-C is part of a complex called the kinetochore, which supports the movement of chromosomes. Two portions of CENP-C, the CCAN-binding domain and Cupin domain, are needed for CENP-C to function. The Cupin domain repeats itself through oligomerization, which is essential for proper CENP-C function.
