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.

The Nobel prize winning physicist Niels Bohr once said, “An expert is a (person) that has made all the mistakes that can be made in a narrow field.” This idea that to master a skill we must learn from our mistakes and avoid making them in future has long been recognized; however, the brain mechanisms and pathways that control this ability have been poorly understood. We revealed a specific brain pathway that allows us to identify and learn from our mistakes to guide better decision-making in future. Our work is an important step towards understanding how the brain controls our daily choices and behavior. The identification of these cells as ‘mistake signalers’ may also help to guide new treatments for mental health conditions associated with impaired decision-making ability.

Researchers led by Osaka University used cryogenic electron microscopy to analyze the atomic structure of the centromeric region of the chromosome, essential for cell division. A protein called CENP-A marks the centromere; the researchers showed that during interphase, CENP-A is bound by a protein called KNL2 to maintain the location of the centromere. During mitosis, KNL2 is replaced by CENP-C, allowing correct formation of the kinetochore complex for cell division.

Researchers from Osaka University have identified a protein, FER1L5, that is essential for sperm to acquire fertilizing ability. Sperm from mice lacking this protein were unable to undergo the “acrosome reaction”, which releases molecules that facilitate fertilization, resulting in impaired male fertility. As FER1L5 is also present in human sperm, this work may lead to new diagnostic methods and treatments for male infertility in humans.

Aspergillus aculeatus
10 Jan 2023
An Osaka Metropolitan University research team analyzed the regulatory mechanisms of carbohydrate-hydrolyzing enzyme production in Aspergillus aculeatus, a filamentous fungus that produces enzymes with an excellent ability to degrade plant biomass. The team found that UDP-glucose 4-epimerase (Uge5), an enzyme known for its involvement in galactose metabolism, also regulates the expression of degrading enzyme genes in A. aculeatus. This is the very first report of Uge5’s roles in selective gene expression in response to different types of inducing sugars in filamentous fungi.

Researchers from Osaka University have developed a culture system using pluripotent cells from southern and northern white rhinos, which was refined to produce primordial germ cell-like cells (PGCLCs). These cells are the equivalent of primordial germ cells, the origin of eggs and sperm. The study marks an important first step in the potential production of northern white rhino gametes, which could be used in breeding programs, and is the first to induce PGCLCs in a wild animal.

Research led by Hong Kong Baptist University (HKBU) involving the use of a pioneering female sterility technique has led to a breakthrough in the production of hybrid rice seeds. Compared to the commonly used “three-line” male sterility technique in hybrid rice seeds production, the novel approach enhances the efficiency of hybrid rice production by eliminating rice seeds that have been produced due to the self-pollination of the “restorer line”. The novel technique enables fully automatic harvesting of hybrid seeds by machines, which can substantially reduce harvesting costs.
