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.

A group including Osaka Metropolitan University researchers discovered that the rhodopsin—a protein in the eye that detects light—of whale sharks has changed to efficiently detect blue light, which penetrates deep-sea water easily. The amino acid substitutions–one of which is counterintuitively associated with congenital stationary night blindness in humans—aid in detecting the low levels of light in the deep-sea. Although these changes make the whale shark rhodopsin less thermally stable the deep-sea temperature, allows their rhodopsin to keep working. This suggests that the unique adaptation evolved to function in the low-light low-temperature environment where whale sharks live.
Artificial metalloenzyme created with improved stereoselectivity
28 Mar 2023
A research group at Osaka Metropolitan University has succeeded in simply creating an artificial metalloenzyme with the common metal-binding motif 2-his-1-carboxylate, which is found in natural non-heme metalloenzymes. They created a library of 12 different proteins and screened the library and found that the H52A/H58E variant had the best stereoselectivity. It is expected that this research can be expanded to produce a variety of biocatalysts that work under mild conditions.
Methods developed for measuring reactive polysulfides in vegetables

Osaka Metropolitan University scientists successfully quantified the total reactive polysulfide content of 22 different types of vegetables, including onions and garlic.

Osaka Metropolitan University researchers have used 100 seconds of laser irradiation to generate convection currents that selectively accelerate biochemical reactions—due to the photothermal effect—by concentrating biofunctional molecules at the cell surface. Using this method, useful molecules can be transported into cells at concentrations a hundred to a thousand times lower than with conventional methods. Furthermore, they also succeeded in selectively introducing small molecules into intracellular organelles usually impossible at low concentrations (hundreds of pmol/L) as well as inducing cell death in targeted cells by concentrating anticancer active peptides into them at concentrations so low that they would not be conventionally effective (several tens of nmol/L).

In hepatic steatosis, hepatocytes "die," resulting in liver damage. Severe steatosis increases hepatocellular deaths, thus aggravating liver damage. The mechanism is unclear. Using mice, we show that mild steatosis causes apoptosis whereas severe steatosis predominantly causes necroptosis leading to cell rupture. This induces strong inflammation and new cell death, producing further liver damage. We reveal the transcription factor ATF3 to be involved in this process. Our results are expected to contribute to therapeutic method development.

Osaka Metropolitan University scientists discovered the principle of light-induced acceleration of antigen–antibody reaction, allowing for simple, ultrafast, and highly sensitive detection of proteins. The researchers introduced target proteins and probe particles with modified antibodies selectively binding to the target proteins into a small channel and applied irradiation with infrared laser light. They achieved, for the first time, the rapid measurement of trace amounts of attogram-level target proteins after only 3 minutes of laser irradiation. These findings will potentially contribute to breakthroughs in the development of systems for ultra-early diagnosis of various diseases.

25 Nov 2022
A research group at the Osaka Metropolitan University Graduate School of Science has revealed a new system that allows them to control the behavior of the nematode worm Caenorhabditis elegans, using two different animal opsins, a type of light-sensitive protein. The first opsin was expressed in the worms’ sensory cells responsible for triggering avoidance behavior, making the worms move. This opsin was found to be approximately 7,000 times more sensitive to white light than the commonly used optogenetic protein channelrhodopsin-2. Likewise, a UV-sensitive opsin was expressed in the worms’ motor neurons, causing the worms to stop when exposed to UV light and start moving again when exposed to green light. Both opsins tested can be switched on and off repeatedly without breaking down, making them robust tools for future research, including the field of drug discovery.
